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

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.

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

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?

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

i trust bigwheeze

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.
