You asked for them... I know the welds suck, but that's not the point Originally Posted by SignWave

Maybe I just need to speed up my welds?

Ok, I have no idea what is causing the black soot now. I just went out and welded a bead quicker than I was before and it just gave me lots of the black soot and pin holes

its the mil scale. trust me. grind it off so there is none closer than 1/2" to your weld. it should come out looking nicer and no black soot.

Really? I sand blasted it about 1" from the edge of each piece. I'll clean it better and try again... Thanks for the suggestion Originally Posted by Canada

Theres your problem. Don't sand blast it. Blasting inbeds oxides and blasting media into the metal contaminating the welds. Since there arn't realy any scavenging agents alloyed into most Tig rods there can't be any contaminanints in the weld zone. We had the same problem at the last company I worked at. I kept telling them to stop blasting everything but they never listened. 45% of production time was spent making repairs

I think this happens in all places of business, where the less informed or less educated fail to listen to somebody more knowledgable. My favorite saying at work for this is " Never enough time or money to do it right but always enough time and money to do it over " Originally Posted by Anti-GMAW

Good to know! So the only way I should prep the surface is with acetone and a stainless wire brush? Or grinder? Thanks again, sorry for the newbie questions Originally Posted by Anti-GMAW
