Ok Thank for the advice i though that steel wont held on SS , but i will try it , as it is a muffler pipe i dont mind about the lokk as long as the welding held the parts

Hello

I have a mig, i wonder if it is possible to weld Stainless steel with it using Stailess steel flux only ,
cause i dont have argon,

I have to weld exhaust pipe

Thank you
