We were asked to demonstrate how to stick weld thin gauge square tubing with the stick welding process. First, if at all possible, SMAW is not the ideal process for welding thin square tubing. MIG or TIG would (in most cases) be a much better option.
However, since the viewer only has access to a stick welder, we are going to show you how it's done.

On the really thin stuff, I like to start my weld in the middle of the sides and run to one end. Then go to the far end and weld back to the middle. By starting in the middle, you’re welding the area that’s most likely to blow out first, before it can heat up. When you run from the far end back to the middle, the fragile area is already fused together which helps dissipate the heat. Just an old fart trick I’ve used for 40+ years.
I'm gonnuh have to try this "old fart" trick. Thanks for the tip. Happy Welding
💪💪
I love bob, exactly the kind of guy you want teaching you.
Fucken Oath. Cheers to Bob
i disagree. you should be banned from doing tutorials like these if you're left handed............... everything you do just looks wrong !!
I like that you blew a hole and kept the video going. It seems like a lot of other weld channels don't keep things real.
Ben Lee I blow up stuff! Like to keep it real man.
Exactly. Here in LatAm : Industrial tubo" is 14 ga or worse. I set my machines to blow and back them down until they blow less. Thats why I mentioned the Arc Pig. You can arc at 40 amps.....HF cheater is all it is but it works. Puddle ? What puddle ? There isn't enough metal to puddle. You're caulking with sheet metal and I prefer O/A but who has time for 50 feet of that....other than Kent,Lazze or someone else getting hundreds of murkin pesoz/hr
Ben Lee he is a welder instructer or teacher either. He blew a hole on purpose to show a point on what can happen or it was an accident he still sealed the hole, he did a good video
Well now I do not feel bad blowing holes LOL
Part of life welding. Specially thinner materials
Holy Cow!!! This helps me so much and is exactly what I needed. I am brand new and have been practicing on the same square tubing. I have been blowing through it and having a hard time starting the arc. It makes me feel better to see you having to "restart" several times to get the arc going and the fact that you blew through was comforting as well. Thank you so much for the tips on how to handle these issues as I plan to build a shop chair with square tubing for my first ever project.
Thanks for doing a stick video, for those of us who are still using Lincoln "tombstones". Every video Does help!
I bought the ac/dc version on purpose as my first welder. Excellent machine!
Damn good video. Extremely applicable to daily life, like you said. Its the weekend, you're on the farm or at home, need to do a repair and just have normal size rods. You run what you brung and adapt. Great video, Bob. Thanks!
This video is a huge help. I recently went through hell trying to stick weld thin tube - the only rods we really get here are 6013, so I did what I could with 2.5mm rods, blew holes all over the place. But after watching this it looks like the reason I struggled so much was running too slow and too cold (55 Amps, to compensate for the heat). That meant I really struggled maintaining an arc, since it was also an out of position weld. Next time I'll try to crank up the Amps and travel faster.
If you run 6013 use it with 70 amps and on straight polarity.
6010 and 6011 are deep penetrating rods. I wouldnt use these for any tubing. Id go 7014 unless its something critical id do 7018 with lower amperage.
I was having this problem too, i upped my amps and was able to maintain an arc and not punch giant holes.
Make sure you always confirm that the welder is actually running a negative polarity on the ground clamp. You have to use a volt meter and check the leads on the welder. You cannot just blindly trust the welder markings because the leads could be backwards inside the welder. Some Chinese welders have reversed polarity and the positive lead is actually negative on a volt meter. This is a major problem on some really popular Amazon arc welders. A positive ground clamp will make your weld at least 3 times more penetration and impossible to run a bead. Try reversing polarity if you don't have a volt meter handy.
Where you from? Because here the only variation of rods i get for mild is 6013 and 7018
Most of "welders" here in my country use a buzzbox wiith fixed @75A AC and 3/32 on everything. Even though they're not professional welders, they make windows, grids for balcony, doors, stairs, etc... and even autobody repairs! Most of welds aren't pretty and most of welds are just tacks but none the less, the work is done. Of course structural and critical welds are for professional welders which I still have not meet one. Some of my friends that weld for a living or have weld on minor things or hobby did not even knew what MIG/MAG or TIG where until I showed them my little hobby setup.
They call it stick welding for a reason, it sticks!!! I am a professional at filling holes. Still working on not making them!!
I thought htey called it that because of the tendency to "stick" the rod to the piece (so annoying!).
Who doesn’t love a nice hole on anything? Builds character to the peace
I'll never forget what I did when makin a stainless grill with tig. Accidently pushed the button and melted off 3cm of one of the rods. I just finished and didnt want to and couldnt replace it since there was no stock. It took me like an hour to stack up welds and half an hour more to grind it into a decent shape. Ended up looking pretty decent
You learn till you die
Thank you Bob for featuring 6013 on thin wall tubing as it is a common problem for us here in Australia as the most commonly available rod at hardware stores and welding supply stores is 6013 and about the only difference in the rods you can get is with how easily the slag is to remove. Cheaper rods = tougher slag, Dearer rods = easier slag.
I love an easy Slag.
@@enlightenednews5265 With a few mates ;-)
Thanks a bunch! You've shown me just what I needed to overcome my habit of blowing holes into thin metal. I'm a newbie and don't weld too often; just once a while when I need to for my own home purposes. What I've learned from your video was the speed technique. This is very important. I also liked the way you photographed the welding process. Thnx again, and keep it up!
I think quite a few pros blow holes too.
I love that you show your mistakes and use them as lessons 💯
I’ve found that holding the electrode like a pen down about 5 inches from the end is a good way to tack things up
You help make feel so much better about being a novice my friend. I'm 44, and just starting to learn. Thanks again!!
im 43 years old and getting ready to go to weld school 2019 live watching channels to learn keeps me positive when i see people starting new careers at my age any advice
Man, I'm 65 and got me a stick welder one month ago, and I'm really excited at making holes (and sometimes a regular joint) on every piece of iron that comes my way. Best regards.
Cool!! Never stop learning!! Sometimes the best way to learn is just jump in there, do it and expect to mess up
Same here, 49, on the waiting list for the next class.
Always wanted to give it a try all the way back to when I was a kid watching my grandfather.
No one is too old to stop learning or taking on anything you'd like to do.
No problem starting at any age...... im also 43 and soon will be changing trades... from industrial commissioning & start up to TIG fabrication and services for brewing companies in my area of the world. Good luck in welding school !
@@henryrollins9177 yhank you you too buddy
new to welding and got a project to do next weekend on square tubing, found this video and it is just what I needed. accidentally in our small town you only get to buy 6013, nothing else, so my joy was great on stumbling across this video. Thanks alot.
As always your video is very educational and full of great information. I would like to applaud your camera person. Great shots every time of your work that helps us to see and understand.
Also the only channel I've found with the split screen showing the "shaded" closeup of the weld as it happens. Awesome.
I got to stick weld for the first time last week. I grabbed some 3/32 plate from the bin because I wasn't listening... This video helped me understand the results I got, thanks!
Love these videos! My weld game has gotten way better since watching your videos Bob! Thank you! Keep up the good work!
Great video thanks not many videos on stick welding thin wall tubing, which is what most DIYers normally weld on for projects at home over the weekend. 👍
Can you show us some more fit ups?
How about T-joints where the one side of the joint is the rounded/bevelled edge of the tube.
Also welding thin wall tube to heavy gauge materials.
And how to weld the inside of a 45 degree corner on thin gauge angle iron.
As many guys commented, here in South Africa it is very difficult to find anything other then 6013 rods so that is what we normally work with.
This would have been super helpful two weeks ago when I had this exact same scenario. 1" square tube, 14ga, building a fence gate frame. Blowin' through like crazy. This vid makes it obvious that my speed was way too slow, and my arc too long. Got the job done with my flux-cored after giving up on the stick. Great video!
New subscriber / new welder here... thank you so much for these vids. Your style both of welding and explaining what is going on and how you go about it is of huge help.
I'm glad to see you popped a hole in the tube. It doesn't make me feel so bad when I blow holes in them as a novice . Clearly , tube stick weld takes quite some skill so if I can get it done it's not a bad learning environment .thanks for sharing
Thanks. The intro to welding class I took fall semester dealt with 1/8” 7018 and mostly 3/8” plate, elements union welders would encounter. But for stick welding I am more interested in joining square tubing to replace the fence around the family cemetery. When I get to TIG, it will be with an eye toward replacing rusty areas on project cars, Rusty and Rustier.
Oh man you couldn't of threw this up at a better time. You just helped my weekend tenfold! Great videos, as always. Bob is the main teacher I've learned welding from. Such a great teacher, thank you for taking the time to do these.
I welded on some of this stuff today. Built a staircase for a mobile home. It’s high speed chicken feed! As soon as arc is struck gotta get to moving.
Bob, ya blow me away. So much you demonstrate and ways to correct mistakes have seriously upped my game. Don’t panic. You and the Hitchhikers Guide. Great job, man.
Sir. I have learned so much watching all your welding videos. Thank you.
Found Bob a couple weeks ago and subscribed. Great videos, very educational. MORE OUTTAKES
For a green house structure using galvanized square 1 1/2 14 gauge tubing I did not not wanted to paint, that's a lot of money and time. So grinding and brushing heavily the welds was not an option. I used stainless steel 312 3/32 sticks with my old Italian inverter 100A.The glass popped out alone, the welds were flat and nice. Almost no haze.
The 420 assemblies (so 420*4= 1680 welds, at the end I was trained) were done like a breeze. No rust in the welds. The SS312 sticks were worth the price.
Twelve years later the structure is like new. I use always SS312 sticks for all my small projects as these sticks are so easy to use and weld any steel alloy and iron.
Grinder and Paint make me the welder I ain't !
Zorn101 AvE & I have been known to say that...
hahaha so true :-)
Like it never even happened lol
@@billythebake AvE! Love that guy also! Constantly makes me laugh!
If you grind to make a weld look good, you are a Grindr
Nicely done with the thinner walled tube. Great technique. Learned a lot in this one video. Heading home at lunchtime to finish a project!!!
When you got serious skills, you can improvise and adapt like a BOSS!
Once again, another excellent video!
I've only just finished welding up some 14g square tube (2mm here in Australia) with 6013. Except I had 2mm 6013s in my welding box (I think that's 1/16). I'm much the same in the way of never reaching for 6013s as a first option. In fact I've grown to hate them over the years, but I knew 2mm electrodes would be the only sensible option. Ran them at 70amps and as much as I don't like 6013s, they actually did really well! As for 3/32, which I think is the 2.6mm equivalent here in Australia. I've done it. But it was really difficult! 😂
Don't ever stop creating great content! I'm always on the lookout for more wealth of knowledge from you! Much respect from down under! 🙏
Seeing you blow a hole, made me feel a bit better. I am too critical and figured I was the only one making mistakes and repairing them the same way as you did. Thank you
Thin wall gal tube and farmers sticks has been my thing for 25yrs of on/off farm welding and so I looked this up to see what the norms have been...well I'm glad you included a mistake or two, that's realistic
I welded exhaust pipe with eighth inch 7018 once. Travel speed is definitely the deciding factor.
On my farm the material i have been working on is 11 gauge 2" galvanized sq tubing. 6010 @77amps on a Miller trailblazer all day long. Not easy at first but doable
I am willing to learn to do that can u help I don't know how to
A drag/stall technique works very well for 6013 on the face of the square tubing, great vid by the by
Nice video, I found similar outcomes using 6013 on 2mm 50 x 50 box section. I had to just weld quickly with a tight arc, it worked but a lot less control of the heat than TIG. I'm just a home user building garden furniture and I use 2mm all the time. Love the videos (from the UK)
Great video man! Thanks. I love the working with whatcha had and then keeping keeping on after you had a blow through.
When you talk you remind me of my dad and my grandpa :) I subscribed. I very much enjoy your videos. You explain things very nicely, the videos are good and thanks. - Ivory
Second time watching this video, and, still, I learned something critical today 👌🏽
I know this is an older video, but my welding instructor taught us with nothing but 1/8th E6011. He said if you could weld different thickness of metal with that rod you could do it with any kind of rod. I have also added 7014 and the 7018 rods for better slag removal.
I'm in Ecuador making a gate out of thin gauge square tube. This was really helpful.
dang! the lighting and just bob is a welder atmosphere. Good job to the video dudes.
I have made several projects out of 14 gauge. I don't weld the outside corner, I feel that if you weld top bottom and inside corner it will be strong enough unless you are building a bridge. All my projects are solid and are carrying a fair amount of weight. Paint it and the outside corner is sharp and looks great. I'm not a pro at all and I welcome any critisism. Thanks for making these videos Bob, you are the best
thanks for that. good to see im not the only one blowing holes in box tubing.
When you finally talk to your crush but you don’t know what to say 1:29
Thank you very much for sharing these tricks. I use stick welding very frequently and I also have found problems such a hole in the middle of the bead. Greeting from México. Arturo Núñez
This is a great video. I'm just at the beginning of the beginning of learning to weld. Stuff like this really helps. Thanks!
Very helpful video. I was always running too slow on square tube with a stick welder. Since moved on to mig for square tube but this is a great video to know what i was doing wrong :)
Thanks!
1/16 6013 seems to be working for me at 35-40 amps. It can still burn through though.
I tried welding for the first time. It was a project creating a frame the basis of it was 1" 16ga square tubing in a square. The joins were 45 degree cuts. I had to order minimum 20' stock so I made lots of cutoffs for practice. Since this is thin stock I used 1/16 6011 at 40-45A. When I practiced beads and did the sides of the join and outside corner it came out well. However, the inside fillet weld always came out ugly. It seemed like it would always want to bead on one surface but not the other. Tried sticking in the corner more, a bit more of a weave pattern between the surfaces, adjusted amps, and tried 3/32. Still same result.
Thankyou Bob , I always learn and enjoy your videos 😎 👍👍 welding happy face here!!!
I find it easier to use electrode positive with thin material and 6013 rods helps to keep the heat out of the parent metal.
This was very useful for a beginner like myself. And I use 6013 3/32", so bonus!
Yeeey! Finally the square tubing welds. Been begging for these for a long time.
This is something I would attempt. Thanks for the video Bob. Always learn from you.
I was just doing something like this. I found switching my buzz box to AC was actually better to keep from burning though. I was glade to here you comment on that.
I only use 7018 for my stick welding needs and I only use it for repairing rusty crap I use my mig welder for all my fabricating and thin metal
You sure know how to stick weld...awesome!
He knows how but I think he needs a lot more experience
This August, I’m taking an arc welding class at my community college. I have zero knowledge or experience so I’ve been watching these videos. What would be a good book to dive into before the class starts to get a head start?
I started welding with 1/2" x 1/2" 1/16" thick square tubing end against solid steel alloy bearing.
After watching this and never welding before, I feel pretty good about my skills.
I used 3/16" 6013.....with $100 portable stick welder.
Perfect real tutorial nice 1 👍🙋♂️🤘
Hi Bob and Crew. Great video! I am learning so much from these. One thing that I have struggled with and had a hard time finding video content for is cleaning and preparation and how to do it fast and efficiently for the different processes and material types like hot roll vs cold roll, dealing with oil/grease etc. Can you cover this topic please. I suspect, like many things, good weld are WAY easier with proper preparation.
Craig Spakowski grinding wheel and acetone.
The quick and dirty fix for oily area. If you can, hit it with solvent, a wire brush, then ether. If you can't: wire brush the chunks off; lay a hot, penetrating bead of thin diameter 6011/6010. The oily area will now be dry carbon powder, that'll clean off with a wire brush. Then lay a bead with thicker stick/ higher amps.
Or heat the area with a pass of a torch to cook the oil, then brush off the carbon. It's a cheat, and not a proper production method.
Hey Bob, nice vid. Real clear instructional video with in-depth knowledge.
I have several holes blown through the project I just completed yesterday. It was...character building to say the least.
thanks a lot for this mind opening video, ive been questioning myself how i should go normal speed and produce pretty coin stacks without blowing a hole, most welding basics tutorials always say too slow or too fast as not good weld.
I feel goood!!!!I always thought it was me or my machine.Now i can sleep with a great smile on my face. Thank's for this great vid.
Indeed an excellent and real vid
Wire size please ?
@@lightrail2823 3/32 stick welding with AWS 6018.
I use 5/64 Blue Demon 7014's for stuff like this.
55 amps or less e+ travel fast.
Can get down to .062 if you're paying attention.
There ya go !
I just started learning to stick weld this week. Already had a chance to fix our mule's engine mount that cracked, was able to slide a 1 5/8 pipe snug into the existing cross member and welded the ends and the seam where it broke. was using 6011 1/16th on my co-worker's cheap little ark welder. Seamed to do the trick on high. Convince my boss to buy a 240v ark welder for me to start learning on so we can fix stuff around the farm
I’ve got a decent entry level AC stick. I made some custom shelf brackets with angle iron and definitely had the amps too high, but would be good to see some of your work with 6013 AC on thin stock.
Very impressive demo Bob! Can I nominate you as a temporary Australian just as long as you continue to produce these helpful videos?
At work we have to stick weld thin stuff from time to time. First let me say I'm not a certified welder I am an ok welder never been to a welding class, and I watch your channel for tips and info along with others. What I do sometimes is beat the flux off another rod and use it like a filler and that cuts down on holes especially when using the wrong type rod like you have mentioned.
Thanks for that tip!
I weld a fair bit of small box section. Thanks for your advice Bob. It helps that you do it for real man.
Here, we usually use 6013 rods even for thin wall tubing. It's only a matter of practice to get use to it.
Always preferred 6011 for light steel, the fast freeze action is what makes it work. Not pretty but effective.
Thanks Sir, this was a great informative video, you have cleared up lots of my problems, now I know I have to invest in a MIG welder.
Thanks
Great job.I have welded lots of this with stick.I have 7018 and 6010.Lots of square and rectangle frames.I welded all but the outaide corner with 7018 and then downhill 1/16 6010 on the outside corner 3/32 7018 rod .The 6010 welds this corner pretty nice
I’m an engineer starting to weld as a hobby. Greatly appreciate your videos. Where’s the best place to look for gas equipment? For mig and tig steel and aluminum
I know it sounds backwards but i found pushing the rod so the weld puddle leads by about 5 deg and weld fast works for me .
As a welder, I have noticed that you don't very often show the puddle, especially on the aluminum video. Can you start showing the puddle view with the shaded lens for the camera so as that the welders may see the puddle characteristics of the weld? Welders know what the front of travel looks like, but, the puddle is were the action is. Thank you.
...The puddle.....yeah, this guy, and Jody at welding tricks .....keep your eye on the puddle...! Bob here is probably looking at the puddle, but the camera may not show that...
I played with stick welding many years back and I never even knew there was a puddle. I learned so much from Jody's videos and what to look for. What model everlast welder is that in the background?
You can.t realy see the puddle of 6013 that is why welding propperly with 6013 takes some practice You have to develope a fel for IT
What is the puddle? Thanks.
Thanks alot for the usefull information.. I wonder why not use the 6018 stick and what are the drawbacks of these?
You do a nice job keeping it real and teaching
great video, I only have a stick at home and this is pretty representative of how my welding of box section goes. I had never tried the flattening of the outer corner, looks like I have a new trick. very informative
Sometimes it helps to start in the middle of the butt weld sides and weld to one end. Then go to the far end of the joint and weld back to the middle. The heat seems to dissipate a little better in the middle that way. Welding tubing thinner than 11ga. (1/8”) is a pain in ass with any process!
I enjoy learning from you and weldtube. Thanks for the videos.
That's what helps me actually learn when welding, even pros make mistakes.
Stop start technique works well for thin material
Good to see real world stuff that the average guy does.
thanks for your time to help us mere mortals
We need a lot more of Bob!!!
Good video as always Bob !. How about using 1/16" & 5/64" 6013 on the same or thinner square tubing. Might be a neat comparison. Also you could use reverse polarity on various rod sizes I.e. 3/32 " etc.
Hey Bob. Just watched this vid. I find it interesting that you would prefer 6010 or 6011 over 6013 for this application. I keep plenty of 6013 around for just this type of thing; I have ESAB 1/8" and Lincoln 5/64". I'm guessing you would have liked the 5/64" rod, as it's about perfect size for that thickness of material. In any case, it seems the shallower-penetrating and less aggressive 6013 is more ideal for this thinner material. I was just curious why you like the 6010 or 6011 better?
@Dennis Young Perhaps, but Bob is very familiar with 6013. He teaches new students to stick weld with 6013 due to it's easy strike and restrike and forgiving characteristics. I do fine with 6010 on thicker (1/8"+) material, but Bob definitely kicks me in the pants using 6010 on thin stuff :-)
Great video man,always pleasure to watch your videos.
Had to figure this out for myself making tool and materials racks! I tried 1/8 and 3/32 7018, 6011, 6013; Also tried 1/16 blue demon and 1/16 lincoln 6011 i think. But for me...as soon as I used 3/32 7014 an BAM..smooth as butter and amazing. Those same racks got modified with .030 flux mig and tig which worked ok but had to break out the 7014 again to get the mod jobs done. Now 7014 is my go too with square tubing! Good luck, btw all of that with old habor freight machines
How does 1/8" 7018 work for you?
A real world test warts and all. Use what you have. Your warts though are pretty good!
Thanks you answered all my questions in the video
GREAT JOB...GREAT EFFORT...YOUR WORK IS MASSIVE
Lovely video. Thank you for the tips and demonstration.
