How difficult is Stainless to weld?
I have a small crack in the forward face under the in-flange of a magnaflo. And was thinking about picking up a small stainless rod to try and close it up..
cast?
old timers trick of welding cast (i learned) is use stainless rod ( high nickel) and weld. Then peen till cool.
