Bob is the perfect example of when people say: "We never stop learning"...even with all his experience he can still recognize when he learns something from a younger person...respect for that Bob!
Aww heck yeah! Said it before, I'll say it again. I like this kid and absolutely love that you guys keep bringing him back! He obviously knows his stuff, yet still humble. Perfect combination for a teacher!
This guy did a great job tig weld the pipe. And he's very respectful to elders as well. Now bob is learning from the young dude. That show you old dog can learn new tricks. Now that I'm pretty pleased.😊😊😊😊
Best way I learned to check for adequate purge was with a lighter, if you have one. If there’s still oxygen in the pipe the flame will stay lit, if the purge is full it will blow argon on to the flame and extinguish the flame
Any breeze will extinguish a flame. He has his purge vents correct in they are on top. Your best bet, start your argon, slow, or you’ll just create a vortex of oxygen and get sugaring, go make your next fit up. What I was taught, and I’m only sharing because you have numbers in your handle and they keep calling one another “brother”,
I have been welding since 68 and still learning, a lot harder doing field welds in a chemical plant, specially confined places, very restricted places , lot of fun, keep on practicing, try walking the cup from bottom up is even more fun, thank you for sharing, by the way I still welding and have a regular job at 70 👍
Hjalmar, I love watching your videos because you always stop to explain what your going to do, and particularly what you don’t want to and why. You make a terrific instructor.
Great video, I only weld as a hobby here and there, but your channels are my primary reference when I need a tutorial. The collaborations are great and show folks that there are different perspectives and ways to do the job correctly.
that was one cool mix weldtube and weld , 2 of my favorites professors . I learned a few new things that are priceless to add to my skill set thanks a ton . you guys rock. I graduate 12/21/18 from combination welding tech . and cant wait to burn learn and earn through out my career
I really enjoyed seeing these two fellas together. More than any other welding duo. The dynamics, humor, respect. I was actually saddened when he left weldtube lol I mean, Abraham is awesome but something about these two guys personalities, they just meshed well
20 years ago, i remember welding lots of sanitary tri-clamp fittings on a manual turntable with a purge hole in the bottom, and tape with a pinhole over the top. probably something like 2mm wall pipe. i would fuse weld the seam all the way around with a purge flow of 15 cfh and about 80 amps. done at the right speed and the inside was almost flush and required little grinding to be almost invisible.
I’m doing something similar with .5” od 316L tubes with a .06” wall, but using filler wire. Getting the turn table rpms correct while backing off the amps about 2/3’s of the way around was the hardest thing about it. I haven’t been able to find many videos using a turntable & tig in conjunction.
Just a tip of advice. If you are welding something big that requires you to purge for 10 mins + do not grind out the bridge tacks when you get to them. Instead stop before them and start a little after the tack and when you have welded everything you can without grinding then you can take all the bridge tacks away at once. The reason behind this is when you grind you push air into the pipe. This doesn't matter all that much on a smaller pipe as you can see in the video but on bigger stuff it can mess up your purge completely. I know this from first hand experience. I had an oxygen meter when doing this particular weld and when I grinded out the tack I had to wait 15 minutes again to start welding
Procedure we use where i work, is a 3/32 to 5/32 gap (obviously bigger gap for the likes of 8" and above, smaller gap for 1/2" pipe) use 1/16 filler, 85- 90 amps and move fast, moving side to side to break down the featherd edge and dipping fast on one side, pulling the metal across to the other. Works well for me. Nice smooth well profiled root, lovely and clean. Silver with a very slight gold band either side. Then again, yanks do love their heavy filler rods and low amps. The carbon procedures we work to all use 115-135 amp root with 3/32 rod, a 1/8 to 5/32 gap and a tiny root face, literally the burr from prepping it wiped off with a file.
I'm so glad helmet tech has gotten allot better my cousins grandpa lost sight in both his eyes and he was the type of person who didnt like help from anyone he liked doing things himself first time I ever seen him cry was when he lost sight watching this video made me think of him.
Awesome respect from young to older and vice versa . Awesome tutorial ,I'm just getting into tig welding and hoping to learn from the likes of this . Thanks
Yea you’re definitely a tube welder that’s why he so good a the dip back feed methods. I’m into pipe world right now and my techniques are unheard of for the most part
i can only listen to someone say "yes sir" so many times. it's obviously him being respectful, but i feel like i'm in the military watching a youtube video!
Nice welding! I also do this using stick with open root. Stickweld it all the way. Ever tried that? Got it on my channel. Seems like alot of time tig is to sensitive. Then we use the stick. Fast and simple process.
when are you going to post more videos? I've been subbed for a while and i'm waiting! I've only done one stick root on stainless. i want to watch more!
I use the key hole method as well. Usually when my gap is too tight on the wire. So I have to feed from outside, the key hole is how I know I'm getting root penetration and it's fusing both sides of the bevel landing.
Recently was taught a rather extreme but effect way to weld your root without a gap Basically sch10 SS factory end butt to butt weld or prepped with barely a 1/16" land, argon at 90+ cfh (this is in a big Fab Shop) 3/4" purge hole, and the you Vibrate more than walk your cup along the seam, your puddle is like 3/8" wide, there's undercut at the front of your puddle that you want to look for, but be careful because too much undercut is the telltale sign that you're about to blow through, you want a more circular puddle rather than a teardrop shape, it's crazy but when down right you can fuse some of those really offset inner diameters
Hi Bob, Great videos! What are those cool ass black gloves you've been using? They look a lot more comfortable than the run of the mill white and brown.
Muy buen video. Pero sería genial si hubiera traducción, ya que somos muchos los de latinoamerica que seguimos sus videos. Les saluda atte Rodrigo de Calama Norte de Chile.
Have you seen those old doors that use skeleton keys? =● when your heat gets out of control, or when your travel speed gets slow, a wide hole opens up, digging a wider opening to both sides of the bevel, hence the word keyhole. Your puddle then becomes hard to control. Jody from Welding Tips and tricks has a video's explaining this with great footage.
Here lays down some nice, uniform work on small bore stainless. Does she like a huge keyhole? That really freaks me out to see that stuck welding, but from what I've seen he does it there too. I also noticed that Frankenstein hood is a prop for his hand as well.
Once I get my new everlast tig welder I really want to learn how to weld stainless. There's a lot of work out there for stainless fabrication and repair in my area.
If this method was used for backfeeding the bottom of monel or hastealloy and sometimes inconel there would be cold wire throughout that root. Should not have to jam wire into the puddle and wait for it to consume. With the right torch angle and heat the filler wire should just “fall off” into the puddle
Fuckk yess boyss!! mannn thats funnn yall make this vid,i was just fuckinn around with a bunch of 4in sch.40 cupins and we could not get the purge down right, but now i know whyy, we were at like15cfh.... sheatttttt and mann ive been lovinnn the keyhole dab technique on carbonn, bestt way to ensuree nice pen

That's how you know good old people
@@nicholaslandolinahuh
Been pipe welding for 8 years now and i still watch these videos just to touch back on basic and see how other ppl do things. Good stuff!
Same here about 15 years now, but always curious to see other peoples methods. Might always pick up an idea that might get you out of a bind one day👍
Aww heck yeah! Said it before, I'll say it again. I like this kid and absolutely love that you guys keep bringing him back! He obviously knows his stuff, yet still humble. Perfect combination for a teacher!
hahaha.....yeeeeeeah
It's pretty cool to see different channels get together.
It's like a crossover episode
Honestly the only thing they are missing is the canned laughter
Fr both my favorite channels honestly
This guy did a great job tig weld the pipe. And he's very respectful to elders as well. Now bob is learning from the young dude. That show you old dog can learn new tricks. Now that I'm pretty pleased.😊😊😊😊
Bob knows it all, just playing the role of the instructor and instructee.
Spoken like a true young dude... Age is irrelevant.
You call that a great job? He destroyed that stainless.
@@jamesbond2472 age is irrelevant, but experience definitely isn't
@@e.collins2768 Usually experience comes with age. Something young people have forgotten
I’ve been welding 20yrs as a career and learn something valuable every time I watch one of your videos. Thank you
Best way I learned to check for adequate purge was with a lighter, if you have one. If there’s still oxygen in the pipe the flame will stay lit, if the purge is full it will blow argon on to the flame and extinguish the flame
Very true if you can but on refineries and Industrial jobs, they're not allowed.
Any breeze will extinguish a flame. He has his purge vents correct in they are on top.

Ixxu zzz zzilzuzuzZzUzkz
j rey shut up, Kim.
Who doesn't weld with a container of butane in their pocket?
The world can learn from this, note the respect both gentlemen display to each other regardless of the age difference.
That's how us welders do.
Great to see the master learning from a younger master! 👍
humility...

These 2 need to come back , always enjoyed the tutorials and content they were able to share
Hjalmar, I love watching your videos because you always stop to explain what your going to do, and particularly what you don’t want to and why. You make a terrific instructor.
Second time I've seen Hjalmar on this channel. Super sharp guy and presents well.
This back feed technique is changing my life
Great video, I only weld as a hobby here and there, but your channels are my primary reference when I need a tutorial. The collaborations are great and show folks that there are different perspectives and ways to do the job correctly.

I’m glad you guys have been showing the back feed technique. Been trying to learn how to forever, great to see what I’m looking for
The student becomes the teacher! That was a good technique, with the filler rod coming from the inside of the tube.
You and Hjalmar make a great team! Mad skills!
how refreshing seeing both generations learning and teaching eachother with the upmost respect.
Its utmost
Mutual respect and consideration opens up a whole new dimension of learning and experience. True professionals here.
Pretty smooth welding and great job on the lesson young dude..I'm 54 , I watched it and picked up a couple good tips, thanks brother
Dynamic duo.
Love you guys!!! Getting an education with every video!!! Thank You!
hahahaha
Bro this is the best video I’ve ever seen the view of root was insane!

Nice to see an old man with a young man
I wish bob and hjalmar could be my neighboors....i could spend afternoons and weekends hanging out with them welding and grillin.😁😁😁
I love these videos where the "ole dog" learns new tricks. Great Video Bob.

The welds look awesome on the stainless
Yea you’re definitely a tube welder that’s why he so good a the dip back feed methods. I’m into pipe world right now and my techniques are unheard of for the most part
wow just gets better and better.... learned a lot man thanks a tonne!!!!
Nice video guys! I can’t even get into that position anymore, never mind welding in it.
Nice trick with the licking the knuckle I always put my face down at the vent and listen.
i can only listen to someone say "yes sir" so many times. it's obviously him being respectful, but i feel like i'm in the military watching a youtube video!
Thanks for the awesome lesson guys.
very nice , good lesson, very talented young man there,,, thanks for the video.
Burn, learn, and earn. Thank you for the motivation
WeldTube videos are awesome, so are Weld.com
Cool video!
Comment no 10
Its rare to see an older welder learn and listen to a younger welder
Man yall make it look easy.
bob just acting bob will run up that 2 inch like notting
Excellent video. Good camera work.
Excellent series.
Both of you very good experience 👏
Looks good! Any chance you guys could do some stainless SMAW?
Yeah that would be nice.
Didn't you put a video up in the 6g position doing just this?
Nice welding! I also do this using stick with open root. Stickweld it all the way. Ever tried that? Got it on my channel. Seems like alot of time tig is to sensitive. Then we use the stick. Fast and simple process.

@@atkinssgaming2179 I promise to upload more before Christmas at least. Got a couple things coming up.😉
wicked man I'm looking forward to it!! Always trying to learn more. Been a pressure welding for 4 years now. I love stainless tig.
Fast and simple but difficult to master. You make it look easy, tight is easier to control for me
I would like to thank you both of you ..iam always see your vedeo. Welding procedure vary wide.
This man is the man
Very beautiful working together 🔥
Does this method apply to welding a turbo exhaust manifold made with sch40 pipe?
Your both hand stable and steady..
just curious why you were using the foot pedal? I know most places that require a test generally will not have foot pedals, refinery,powerplants etc.
Bumped into Bob the other day at the welding supply
Great video..! Thanks for sharing.!!
I use the key hole method as well. Usually when my gap is too tight on the wire. So I have to feed from outside, the key hole is how I know I'm getting root penetration and it's fusing both sides of the bevel landing.
Both guys are awesome
Pardon my welding, but did you use a cutting disc for grinding?
A little moment of that has injured, seriously many people...
Thanks for the video !!!! 😎💯👍
Nice job, and yes this old dog did learn from you and Bob on technique in this vid, keep the vids coming everyone can learn new things. Thanks

Dang bro ur balancing ur hand in the air as u feed 👌🏽
Another great video Bob and I like the kid. Very knowledgeable and respectful. Would be very valuable in the UA program.... ;-)
Hi Bob,
Great videos! What are those cool ass black gloves you've been using? They look a lot more comfortable than the run of the mill white and brown.
Coolest channel about weld !
Muy buen video. Pero sería genial si hubiera traducción, ya que somos muchos los de latinoamerica que seguimos sus videos. Les saluda atte Rodrigo de Calama Norte de Chile.
Rodrigo Balcázar English ? I don't know what your saying. thanx
Hiii amigosss congradulation 😄
Great information Thanks to you both
Use a zip disc when cutting bridge tacks. It will be a lot cleaner than using that big 1/8" and won't need to take a burr out.
weld . com. thanx Bob !!!
Thanks again good welder brothers👀
Great jobs guys! Always interesting to learn from a different perspective. Well done!
do we get to see the cap passes ?
As a beginner could you do a detailed video on what a key hole is?
Have you seen those old doors that use skeleton keys? =● when your heat gets out of control, or when your travel speed gets slow, a wide hole opens up, digging a wider opening to both sides of the bevel, hence the word keyhole.

Im welding 4,5 inch 2mm thick stainless steel pipes. Got any videos on something similar? All videos are on some extreme thick pipes.
I love Wielding 🥰
i use that on iron but whit stanless i dont work with the rod inside only for iron, keep the good work, soldadores portugueses estao no top 5

great video thanks you guys....thanks from Portugal...
Great video. Very infrormative. Thank both of you. Dan
Any chance there could be a demo video on a rollout weld on some 304 stainless tig all the way out?
how do you keep your tape from not melting and creating smoke?
Fuckk yess boyss!! mannn thats funnn yall make this vid,i was just fuckinn around with a bunch of 4in sch.40 cupins and we could not get the purge down right, but now i know whyy, we were at like15cfh.... sheatttttt and mann ive been lovinnn the keyhole dab technique on carbonn, bestt way to ensuree nice pen
Hi guys just love your vids.Could you please do a box type boiler tube test?
Hey can yall show some stuff on 10inch shd 80 on stainless steel
Does this work for carbon pipe too or just stainless
Gracias bob x tus consejos
