Some Seam Weld Photos
#82
Wire wheel seams, scrape out what sealant you can with a carpet knife then heat up the seam with a hand held torch and wire brush whatever burnt crap escapes. Once the sealant you can't see has burned, when the mig wire hits it doesn't booger much if any at all.
Left most weld was the first which I didn't "burn" with the torch, heated the rest up and wire brushed the ensuing soot and got much better results

This is a scrap piece of the car, I'm still new so any advice is appreciated.
I see growths, I imagine I need to get it cleaner? How would I clean between the seams?
Update: Sounds like burn the area with a torch is the solution to cleaning between the pinched seams?

That's why I used the word stitch. One Bead, wait for orange to cool, then another. Repeat as necessary. It starts to go pretty fast. Not ideal for structural steel building, but fine for a seam on a car. Wire size can have a pretty big effect too, but . 030 sounds fine.
Edit: maybe stitch wasn't the best wording for what I was meaning.

Stumbled on this thread while looking at other people's seam welding. Hope to have pics of my subframe rails and seam welding in the next coming weeks, Chassis is stripped but still removing seam sealer, one panel at a time.
So far, all I've done is subframes and control arms, and other various parts. I had them sand blasted and that saved me prep time. On the Chassis parts I have done, I've used paint stripper (muratic acid) and scotch-lock buffing pads to clean the areas. So far, so good!

Not a pro over here. I fully realize I may be doing it all wrong. I would love suggestions on how to do it better.
Less heat was fat beads with less penetration.
I have a bit of vintage Mazda miata sheet I've cut off to run beads on. I will run and take a photo of any combo setting on this wire and gas.
