MIG Welding Stainless Steel

[@JeffKreska]

Did this weld right the first time? How did you know to turn down the inductance? I would love to see some of your trial and error videos.

[@bobmoffatt4133]

Jeff Kreska As I explained at the first of the video, helium causes a hotter arc. Needed to counter that to have the weld freeze fast enough.

[@robertschmitt9160]

Ask ESAB about their metal core stainless wire that you can run with straight argon. That's what I use at work.

[@damianarana2919]

Hey Bob, love the calmness you do your very great and helpful videos. I do need some guidance, I am currently welding 316 to 316 and am using .035 316, would that be the right wire for the base metals?

[@mjbop1]

Could you do pipe welding with only a MIG machine? What wire and settings would be appropriate? root, hot pass and cap?

[@tone1myth2ad]

We use to use that tri blend mix at the company i work for, it was the best gas to run with stainless steel. Our material thickness were a lot less though, 14 and 12ga . We're currently using Stain Lite as our shielding gas when mig welding, I'm told its a tri mix as well but it doesnt have the percentages written on on the cylinders and i am almost certain it doesn't have helium. Helium was the reason they switched saying it was to expensive and a shortage of the gas blah blah blah, The Stainlite is good but i still think that Tri Mix was better, it gave a better color to the weld and the weld puddle , puddled better

[@mrgreenswelding2853]

How do i set inductance for aluminium spray arc pulse mig? Pretty pretty please???

[@madderoftime]

I'd like to see a cut and etch on that part. What can be done to get rid of the peak in the horizontal fillet with this wire and gas running that hot?

[@Equiluxe1]

It's better to use an Argon Helium O2 or Argon O2 mix on stainless as the carbon in CO2 causes staining and also can form Chromium carbides.

[@piksna18]

Hi Bob! I really enjoy watching your videos and advice but it leaves me often wondering about the penetration. Would it be possible to include that in the videos?

[@Welddotcom]

Certainly.

[@longevitywelding]

Nice video Bob! Love your explanations.

[@cubul32]

The weld itself fuses the metal only where the bead touches it? Where the two pieces of stainless touch each other (the narrow face/edge of the vertical sitting on the flat face of the horizontal) there is no fusion there, is it? Trying to understand better the welding process. If I were to grind that weld to 90 degree corners, the two pieces would come apart, right?

[@vapido]

any chance you could give tips on thicker stainless? I have to weld an 8" OD 3/8" wall pipe to a 5/8" flange (a pole mounted to ground essentially, with gusseting to edge of flange) . All stainless. I do a lot of art (large scale sculpture) welding from stainless using .035 wire and 98%arg/2%c02 with great results, but this would be a multi pass. I have machines capable of spray and have bottles of tri mix, but was looking for some techniques for doing multi pass or spray on thicker stainless. I just worry about how to handle the heat since it gets so concentrated. really appreciate your channel. its been a great resource and has definitely helped me improve my mig techniques and my understanding of what is going on.

[@RameshKumar-nk7ik]

Which gas use for steel welding in MIG welding machine

[@georgeowen2083]

Damn that’s speed welding.

[@reedsfab3828]

Thanks for the video Bob

[@tryscience]

Beautiful weld

[@roberthoovan4130]

Can u run co2 as ur gas for welding ss

[@dwiltd]

Can you use C25 for this?

[@justinorman8608]

Nice video Bob. I've got a project I'm working doing some outside corner joints on some 20g 304#4. Would you have any advice for me. I've been using the tig process but mig is also available to me. Thank you

[@bobmoffatt4133]

Justin Orman .023 wire if you can. Man that's thin. Be careful.

[@justinorman8608]

Thank you

[@StreuB1]

Nice video Bob!

[@claytonparks9469]

What does the inductance setting do?

[@planeswalking]

"The inductance setting on a mig welder controls the rate of current rise following the short-circuit state. That is during the time when the wire is short circuiting into the weld puddle. This setting affects the arc time too. That is the amount of time the short circuit cycle spends arcing and providing heat to the puddle." --weldingtipsandtricks basically, you increase inductance if your puddle needs to be wetter, and you put it down if you think it will get too wet. in this case the helium will make the arc run hotter with deeper pen, so the puddle is more likely to flow off on you, so he dialed it down a bit to compensate. not a mig welder per se, but it's similar to how i set my pulses on tig. inductance is like a fine tune after you found your wire speed and voltage setting.

[@Welddotcom]

More inductance = "wetter", more fluid puddle.

[@troygreiner652]

I run any were from 28-30 to 900-1000 on thick stainless

[@donaldinnewmexico]

Bob, Man you were moving fast. How about slowing down the wire speed some for the horizontal fillet? Could that eliminate the peakedness? Thanks, Donald

[@clevelandmortician3887]

Donald in New Mexico would make it worse. Ive been welding stainless mig for some time now and still have that problem. More heat and less wire speed helps only a little

[@clevelandmortician3887]

Donald in New Mexico sorry. I misread your comment. I thought you meant travel speed. So yes, less wire speed helps. Sorry sir

[@donaldinnewmexico]

Thanks for your answer CM. Donald

[@robertavery8897]

Did you try flux core.

[@nathanmooney3592]

Do you know why I'm getting dark grey scale on top of my welds? Could it be wrong shielding gas?(100% argon is what I'm using)

[@snakeeyes7751]

And how u set up the conductance ?...plz help me out..idk how i use the conductance for stainless i mean...im new in mig welding

[@speedster1fast1]

My local gas supplier no longer sells tri gas, I can't get helium. All they will sell is some " star .... Something" What other gas is good for stainless mig?

[@tone1myth2ad]

Stainlite

[@torcher78]

speedster1fast1 c10

[@speedster1fast1]

Thank you, I'll ask about that.

[@JCassidy3383]

Did I miss the word for the week....? Didn't see it pop up.

[@Welddotcom]

1:33

[@speedster1fast1]

JCassidy3383 I seen it.

[@JCassidy3383]

Weld.com wow, how did I miss that!? Thank you!

[@pauljohnson-yk5dq]

I've done some repairs on exhaust pipes using my mig welder. One thing I've consistently noticed is that rust occurs mainly on the weld joints, and not so much on the aluminized steel pipes themselves. Is it possible to use stainless steel mig wires with tri-mixed gas to weld these pipes and create weld joints that don't rust?

[@blw5005]

That is exactly what you have to do. Using 75/25 gas introduces carbon into the weld and allows it to rust. You could also use flux core wire and not run gas but the welds aren't are pretty.

[@blw5005]

Oops, 3 year old comment...

[@TheBeladog]

Thanks. Good vid

[@MrMonnster]

160 amps? we are using like 260-300 amps for 6mm material

[@fhsrgadfasdf]

MAG welding?

[@EricWithTheBass]

TRI-MIX - 90% Helium - 7.5% Argon - 2.5% Co2 2.5% MAG welding :D but ur right tho :P

[@danititus6150]

Anything involving co2 or o2 in argon is considered MAG welding,as these 2 gases play a key role in the profile,penetration,aspect,mechanical proprieties.MIG=metal inert gas, MAG = metal active gas

[@jjtmmjjmm2113]

Stainless separates the men from the boys

[@tryscience]

So do the police

[@dougankrum3328]

Looks about right for stainless....gas? usually something like this...90% helium, 8% Argon, 2% C02....

[@heavymetalworks6375]

Looks a little hot to me. but that my 2 cents

[@ffgfvggxcvhbfcvvcdcc845]

surely if your using 1/4 “ stainless plate you would use 304? 309 is dissimilar for welding mild carbon steel to stainless!

[@easymoneyism]

That wire runs so fast

[@Apeattacksurvivor]

Yes it does lol stainless loves wire

[@just_rest4208]

I do

[@just_rest4208]

You had no color

[@alexlacroix8435]

That weld is terrible, is this guy really an instructor?

[@melgross]

Are you really a welder?

[@Coreykishbaugh]

Please take the chuck key out of the chuck on your positioner. It is a terrible habit.

[@bobmoffatt4133]

corey kishbaugh Thanks for noticing. Power is off and I need it in there when I put pipe coupons in by myself. It's always removed when power is on.

[@user-sc6lp1om9y]

RIP ear drums! holy cow, who ever is doing your editing please use some sort of sound leveling, my heart and ear drums will thank you!

[@nickpowell3330]

Do a t joint 18 gauge stainless GTAW

[@GigaDonk]

Does esab email you if you win or is it only on facebook on sundays? i don't see who won.

[@GigaDonk]

nevermind i'm just not used to facebook.
