To the folks questioning using 309 filler on stainless, I have a little anecdote. Some years ago, I had prepped for a cross country motorcycle camping trip, only to discover a cracked weld on the exhaust header (commercially welded 304 stainless, not my weld, O2 sensor bung was lifting off). I had picked up some 309 mig wire for another project which changed direction and the 309 was never opened. I'd never welded stainless. I'd never welded anything this thin. I only had standard argon/CO2 at hand. Watched a couple TH-cam videos on how to do it and let 'er rip. The exhaust weld has held up for many thousands of miles since, even more miles than it had when it cracked.
@@imaouima I believe it was 98/2% Ar/CO2. The bottle was "Stargon" but no specific blend labeled on it (i.e. not identified as Stargon VS, Stargon CS, or Stargon SS).
98% ar/co2 mix works also. alot of splatter with short-circuit mig so it's a no-go. Mig work great on thicker stainless steel but with spray arc or also for production work with pulse mig.
Kevin, I'm using a miller access 450, v groove rollers, 308 ss wire from a barrel, 98%A 2%CO2, and I believe standard contact tips. I only get about 3 minutes of welding before I get a unstable arc and the tip is shot. My rollers are pretty clean and the wire is feeding pretty good. Why are my tips burning out so fast?
I feel your second side is more consistent, your first side where you "whipped" has a wavy edge like an ocean. For those asking about the shielding gas, well Helium adds heat to the low heat input characteristics of GMAW-S. Someone else commented about using 309 filler on stainless to stainless, and I will too, what are you teaching us here? Either way, thanks for giving it a try and helping out the welding community.
I'm welding 8000 sf coal bunker all stainless and some carbon were running 309l .45 wire I can not get rid of cold roll on the sides and tall and cold roll tryed push pull chaing stick out angles up in volts down up in wore speed and down my welds have the lease cold roll to others and when I tie in 3 bead stringers you cant tell but how do I get rid of it I'm running mostly vertical and horizontal I'm running 25.5 to 26.5 volts and 325 to 380 ipm
Now without the "greying" as you mentioned, would this be safe for food contact? Im looking to weld up a evaporator pan for boiling maple sap and before i take the plunge to invest in a tank i just want to know its realistically achievable with a mig. Thanks bud
bob was there a reason for choosing 309 for stainless to stainless ? is the trimix necessary or just better than argon? sure is a nice looking weld. thanks for your very informative videos.
larry sperling I have the same question. The 309 I used was no good on my last project. I also used Argon and not tri-mix. I kinda think that was my mistake. I am looking for more on this subject.
I’m new to stainless steel mig welding. I’m overlaying a36 with 309 using 98/2 o2 spray transfer. Is it normal to be gray and have a little black scale on the surface before cleaning the weld? Is that silica? Any tips are appreciated. Thanks
tnx for your informative video, what mig settings should be set on our welder machine for 5mm flat Y-butt (3mm gap) weld of stainless steel in order to achieve spray arc transfer mode?
You 'can', but the high carbon contents will eliminate the materials' stainless properties and rust much more likely. With MIG/GMAW, use either tri-gas or Argon+o2 (99/1 DCRP or 95/5 DCSP) to preserve the stainless properties. Use c15/25 for your own projects, but not for customer projects.
Thanks for showing, #s too!! Was says reverse current but says pulsating arc transfer... that’s can’t be... for a 316si... pulse wouldn’t work... not familiar with rmd but that wouldn’t fly.... mig setting 21 area was good sputtering wire so I’ll go from 230-250 to 310-340?
@1:35 *finishes A+ stitch* - turns to camera with meaningful eye contact Someone needs to edit in the thuglife glasses at this point yes im being a goof.. seriously great video.. as a newbie to mig i was paying close attention .. sub'd!
Hello I want to be able to weld thin 304 stainless and also Aluminum. I have a mig welder and even on the lowest setting it blows holes through it. Do I need a TIG welder or is it the different gas i need I just have a nitrogen tank.
Good video. I like how you explain the reason for the sound. Are you looking for or seeing anything different with the puddle vs. ER70-S6 in carbon. Love to see you do a video with dual shielded flux core on stainless.
It will not rust as long as you do not touch it with carbon steel. Use stainless brushes. Stainless WILL rust if anything carbon makes contact with it. You can actually scratch it with a nail, and that scratch will rust. Its harder than iron, so the iron will actually deposit itself onto the stainless, and oxidize.
I went to a weld class for 2yrs.we used a tensile tester. what you did there both times would have been passed without a dought.i believe a stitch well would have been stronger.ya get more weld in the deep part of the joint
Not easily, but the filler's job is to retain the properties of the base materials. However, a weakness of 309l filler is water/marine applications, as it contains no molybdenum (while 316 does).
Just curious, I am welding RA 330 and I am having a hard time getting the weld parameters correct. We are using .035 RA 330 wire and 100% Argon welding on 3/8" material. Any thoughts?
When you're doing welds on actual pieces in stainless, do you run gas to the back side as well? I've always thought this was necessary to keep it clean.
What material is this wire. I got some flux core but never known what material this would be. I've seen a guy weld regular carbon steel, mild and a plate of stainless all together
Man short circuit stainless is night and day to pulse stainless. Used to be able to pulse stainless all positions and struggling to do so with short circuit which is so ass backwards haha
I wish you would have explained the inductance feature a little. I had my all the way up and would doing terrible. Of course I was running strait argon and was welding with 309 instead of er308 so, I don’t know. Also, it was with a Lincoln 210 muti-process that was in awful shape. I just could not get a stable arc. I was all over the dial trying to find the sweet spot and just couldn’t. That almost never happens to me after 9 years in the field. So, I would really like some feedback if possible. At least on the advantages of adjustable inductance. I’ll be looking for more vids. Always liked watching your vids Sir.
I always have used c10 90 10 mix short arc thin materials spray transfer on thicker material. Built many oil tanks and such with it. Many ways to skin a cat would love to try the tri mix but dont do much stainless work anymore.
Can i weld 22 gauge stainless steel without distortion on the pans I want to make? I would like to make a raised flue pans for maple syrup and I can run a not never a tig. Also splatter seams to be a problem. Tig vs mig. I like the mig and speed of it. but tig much slower but less clean up. Love your videos thank you for posting. I learn so much from you.id buy you a beer if you were here cheers..
i thank you for your time and effort to help noobs like me , but i am certified because of my skill honed due to the confidence you gave me , that extra match under my rump if you will but im certified under AWS GMAW MIG D9.1 1/8'' A36, 1F fillet weld certification
Hey Bob, I always appreciate watching your videos.. I have a question : At work, I keep getting black suit on the work material (316L).. what causes this and how do I fix this? I'm welding with a HeArCo2 mix on 5/16 - 1/8 fillet... downhill running a 0.035 wire at 28V@400ipm wire speed.... can't tell you travel speed... this setting causes excessive spatter and black suit... I have tried everything from angle to terminal distance.. have not played with inductance or gas flow though... also tried different wire speeds.. best result I got was with spray transfer but was not practical holding that flat position.. (10' diameter reservoir on rotating positioner) Thanks again for these instructive videos..
What is with the high peak in the center of the weld? that isnt normal to me along with all the spatter. I've always been taught that was bad and the weld isnt correct?
335 wfs I believe is the issue, I did a lot if mig welding ss for a while, the amperage he had the machine set to was about right, but the wfs I typically set around 215-245 depending upon circumstances. Side note, most of the material I welded was the same thickness as his in the video
Ahh💡, your stitching routine acts as a metronome to gauge speed. I wonder if you actually used a metronome if it could help train consistency in your pace, stitch, etc. yup trying this lol
I used c25, 308l wire on 304SS, 16 gauge 3" tubing and had a very hard time getting nice looking welds. I can't purchase tri mix here, just rent at a huge cost.
I like the push and pull way but I would do more push and pulling to get the pattern finer but may deposit more heat but yeah idk lower amps and go slower and more push and pulling and may get around dumping less heat into it... trail and error
because I work for distillery product manufacturer in Boise Idaho ( Corson Distillery Systems ) companies making plenty of money but we have a long turn out right from from my point of view because of only tig process is being used and not modern technology attachments at this point
Yeah that's what i was reading on 309 wire on the Lincoln electric website. But people use different wire and different gas so it seem to depend on who you ask...
Helium makes you talk like a duck, so I guess it's not that strange that it makes your weld sound funny, too. So what about 316 stainless? Any differences?
Haha this guy is one of the best welders on TH-cam. Welding stainless the penetration is higher than normal steel you have to be careful traveling to slow as SS will warp easily when cooling due to overheating.
I was given an old MIG welder and trying to make sense of the thing. Your method of instruction is excellent Bob. I feel smarter already. Thank you!

Up until I bought a Tig machine about 4 years ago, I would stainless Mig weld everything... Very handy for some applications.
He's so modest, great welds.
Helium changes my sound too. And that’s ok. It’s what I want. 😂 love the video 👍🏻
This is great, thank you for being so thorough.
Is that weld water tight?
Does 100% argon works too?

David Finch if you stock 309 for dissimilar metal welding or cladding then it may be easier to use that then to purchase separate 308 filler
Love your vids man!
Can you use 75-25 mix
What's the material thickness?
So, CAN you weld the stainless steel with normal 75% mig gas?
Where can I find 4F stainless mig?

Other than adjustable inductance does your machine have to have any special features to weld stainless?
That is a professional welder .

309l

Love to see you do a video with dual shielded flux core on stainless.
It's work on thin gauge sheet?
20 gauge or 18 gauge
very nice job and well explained, I wish I could weld like you
Beautiful and stable weld
I do an "E" motion when making a mig weld joint like that better consistency and always gets great pentration and wont fold on a breal test.
is this the same method one would use to repair a reefer refrigerated trailer?
can this be done with 100% Argon?
Stick to knitting 😀
If you switch to a TIG-machine, then yes ;)
Do you have to paint over the weld or it doesn't corrode?
It will not rust as long as you do not touch it with carbon steel. Use stainless brushes. Stainless WILL rust if anything carbon makes contact with it. You can actually scratch it with a nail, and that scratch will rust. Its harder than iron, so the iron will actually deposit itself onto the stainless, and oxidize.

I've never really seen a T-joint in a Tensile tester....
David Finch no i haven't either but a fill weld is a fill weld the technic that he showed was on point.
Um wondering the best type for welding [ AISI type 304 ]MIG or TIG ?????
SO if I have stainless still headers for a vehicle and want to do a repair on a crack; would this be the correct way
TIG would be ideal
we hundred percent sure though??
I was just asking, after reading some articles, mig was also said ok
You could hammer a finishing nail with a 16lb sledge hammmer if you really wanted to...and that would be OK too.
@@RK-kn1ud yes, of course.
Will a 309l weld rust at all?
Not easily, but the filler's job is to retain the properties of the base materials. However, a weakness of 309l filler is water/marine applications, as it contains no molybdenum (while 316 does).

Peter Petruzzi it’s your gas
I don't weld much and haven't tried on stainless, does it work well just with argon?
When you're doing welds on actual pieces in stainless, do you run gas to the back side as well? I've always thought this was necessary to keep it clean.
all depends on he thickness of the material.....the thicker material does not usually need purging..Paul from weld.com
The erratic/unstable arc sound is what has been bothering me, good to know that is normal.
It sou ded dirty and contaminated. Al.ost sounded like the flow meter froze up
What material is this wire. I got some flux core but never known what material this would be. I've seen a guy weld regular carbon steel, mild and a plate of stainless all together
Do you have to use a tri-mix,is there a alternative?
Tri-mix is the best, however there are alternatives. You can use 98% Argon / 2% CO2 or 98% Argon / 2% Oxygen as well.
thanks much!

What ESAB MIG Welder is this?
Rebel 235
What is that, about 3/4" in. stickout?
is stainless wire available with flux ? I got an entry level Lincoln (120VAC) mig with no gas connections.
Yes, but you'd be better off with dual shield flux core and that means gas.

Do you have to use the helium tri mix in this process or is argon/co2 mix sufficient? Very nice video. Thank you
Don Zon - try 2.5%co2 balance argon with pulse mig is best for this thickness.. Perfection!
How can you cut the splatter down? On carbon steel I get none but stainless I get some and it's annoying
You need a different gas for stainless
+Een Rookworst I use the tri mix for stainless
+Eddie Barbee maybe try a shorter stickout, to much wire speed, or torch angle

Shouldn't his mix be 90% argon 7.5% helium and 2.5% CO2
Jay Mac All depending on where you live in the country.Gas suppliers change there mix up a little bit to save money.
FOCUS!
is this a sanitary process?
so you can weld stainless with a MIG, that's intresting

I think the wire speed is a little fast . In my opinion. Just a hair
Respectfully I don’t think this guy ever run stainless wire before.
Shouldn't you use 308? Isn't 309 for carbon to stainless?
Yeah that's what i was reading on 309 wire on the Lincoln electric website. But people use different wire and different gas so it seem to depend on who you ask...
Runs better if you run n.o.s
You guys, this is not how you weld stainless, if you have any splatter it's bad, stainless is ment to be welded hot
This guys an instructor?,, stitch and oscillation is not the same technique🤔👨🏭
I wouldn't call either weld acceptable tbh
Here comes the internet pro
Helium makes you talk like a duck, so I guess it's not that strange that it makes your weld sound funny, too.
So what about 316 stainless? Any differences?
Welded both sides to fast will have Por penetration
Haha this guy is one of the best welders on TH-cam. Welding stainless the penetration is higher than normal steel you have to be careful traveling to slow as SS will warp easily when cooling due to overheating.
