Welding stainless
 

So Im using my dads wire feed mig. Its a 75/25 mix, and i think that it has .030 wire, but I dont know for sure. . So the other day, I was wondering if I could weld some Aluminized Steel pipe to it? So I said ---- it ill give it a try. If I ---- it up oh well I just buy a new wastegate flange. I was told that this mig was set up for welding steel. So cleaned them bolth up real well on the wire wheel and I gave it a shot and it it turned out good. Im just wondering if now once I hook everthing up if its gona fall apart. Im new to this whole welding thing but I can get some half way descent beads.

As long as there is good penetration it'll probably be fine. Be aware though that wastegates put a lot of stress on a single pipe and need a decent amount of metal layed down.


Put some gussets on it if you worried.

stainless is kinda funny though.....your not really supposed to even use filler rod when welding stainless with a tig welder...your supposed to kinda let it combine itself and then use the filler where you burn through.....so i dont know about mig welding it....doesnt sound like the best idea .......i would imagine it would work fine though...probably wouldnt want to build something to support myself with that though..not that you are

Re: Welding stainless
 

prime example of internet misinformation. antogenous welding should never be done with stainless if you want a strong weld. adding filler material when using the gas tungsten arc welding process on stainless steel is nescassary to create a strong weld.

i hope you aren't a certified welder.

Re: Welding stainless
 

i am not a certified welder.....ill look into that....

Re: Welding stainless
 

Weir,

What about orbital welding, where the there is no gap, etc, etc. How do those welds stack up? Are they the same thickness as the material being welded?

Re: Welding stainless
 

I'm Certified by AWS and WABO for TIG and Fluxcore. You're retarded, you need filler metal. You have a stong weld by penitration and weld throat. Concaved beads lack the strength of a convex bead. The only welding you dont use filler metal is Electrobeam Welding.

im not being a jerk but i dont believe you.....my veteran nuclear something or other welder for the navy teacher told me this and showed me how to do it on a manifold....so you little patches or whatever you have...dont mean ---- to me...im gonna trust my genius welding teacher

Re: Welding stainless
 

i trust bigwheeze

Re: Welding stainless
 

I trust my welds. If it falls off I will let you know. Little experiment. HF Cast Iron manifold to Aluminized Steel pipe to stainless steel wastegate flange. Going to heat the ---- out of the manifold with Acetylene Oxygen then atempt to weld to it. O0

Re: Welding stainless
 

it will work thats how me and my brother did his external on a 2g mani for a dsm that was cast

Re: Welding stainless
 

I just stick welded the mother fucker
steel flange ont a cut cast mani

Re: Welding stainless
 

god damn your a ------- idiot.

Re: Welding stainless
 

Where does the filler metal come from when welding a pipe 1/4" wall V groove? Magic? Tell Mr. Vetran Nucular Reactor Welder to find a new carrer something he doesnt suck at. Ask him for is AWS ( www.aws.org ) certification rated up to G6R. At the most if he is certified hes only rated to G4 which limits him to plate 1/8" - 3/4" thickness FHVO Groove and fillet welds. On mild steel using ER70S- filler metals. Don't care if you've welded 1 year or 50 years, wrong is wrong.

Re: Welding stainless
 

when your butt welding stainless pipes together.....i assure you your wrong

Re: Welding stainless
 

ARE YOU TALKING ABOUT PULSE WELDING? "Certified welder" is a term that gets thrown around a lot. You usually get certified per job and it expires when you're done with that job.

ps i don't want this to piss off anyone who knows what the hell they're talking about.

Re: Welding stainless
 

Its a ------- wastegate tube not a rocket ship. Just ------- weld it.

Re: Welding stainless
 

well said

Re: Welding stainless
 

Hey, that is the most important weld on a manifold. ;)

Re: Welding stainless
 

agreed. bottom line is if it works and doesn't crack or break, then it who cares?

Re: Welding stainless
 

Yeah pretty much you're either a french canadian or just a stupid ass mother fucker. Didn't I just say I was AWS and WABO certified. Reading owns you.
Heres the proof. "Pulse welding" is a pulsed current. "Certified Welder" maybe thrown around where they breed retards like you.

Re: Welding stainless
 

so you went through the trouble of removing your last name up top but left it on the bottom? :P

Re: Welding stainless
 

It had more than my last name. But I left my last on the AWS because if you ever remember a thread awhile ago ScottSI said my last name. Just one more thing proving they are mine.

Re: Welding stainless
 

My .02 as a current tig student is you defintly need filler for plate and such. thin wal exaust tubing if its stainless i think u can just fuse them with out filler but thats just a guess from what i learned so far. i can tell u that if u used regular mig wire on stainless pipe the weld bead will rust and the rust will kida ------ out a few inches down the tube from the weld. it should hold i think just dont expect it to last for ever.

Re: Welding stainless
 

No strength what so ever without filler metal. Go ahead and try dont bitch when it falls apart.
