small stainless weld help

admin

What am I doing wrong on this weld.  Stainless with 98/2co2, yes it is on wood because I use that to prevent contamination.  I do all my wire brushing on plywood on the table.  Tried pulsed spray for the first time on this and looks like I don't have it dialed in all the way yet.  


Reply:I see a rod welded to a washer in the picture.  Is that not what you were trying to do?   If that is what you were trying to do, what is wrong that you see with those welds, or what?   Not exactly sure why you're asking what you're doing wrong.

1st on WeldingWeb to have a scrolling sig!

Reply:Judging from the BBs I reckon This is Mig??It does have a strange look to it, but it looks like good penetration.  Is that silver spray paint or just the picture?What exactly are you Making or repairing?
Reply:Trimix wasn't used which would account for the discoloration

Reply:I agree 👍 Something are just easier with TIG. Dave

Reply:They are tack welds and look to be pretty hot so you're going to get a bigger crater. The finish on the washer may be contributing to the odd looking craters.
