Stainless restaurant prep sink. Can't find any specs. Looks to be 16ga 304. When fabbed, they tacked a few times from the bottom, welded tight on top, THEN, they ground WAY too much material and it is separating. Thinking backer plate and fill the separation. Opinions? Advise?

The best thing would be to close the gap. If you can't you could lay some 1/16" filler in there and walk over the top of it to fuse it all together . You can end up with a big joint but can be build up and shaped afterwards. It is what it is.

i'm guessing your showing the bottom of the sink

i'd tap the seam back and tack then weld it up from the inside

Run about 65-70 amps. Use 1/16 or dab at it with 3/32

if you can get behind the seam i would use a chill block then from the front tack it up nice along the entire seam then weld

ID close the seam up, speed tack it every 1/2"-3/4" and weld across the entire seam, pulse if you can and use some small diameter filler. 2.5pps, 50amps, 75% peak, 25% background, .030-.035" filler. The backing block will help you but at those setting you should be able to weld without blowing through.

Lots of good here. Solution I am picturing now is a combo of replies: close, chill, tack, build, shape.

My concern would be warping. I'd just tack every few inches from the back side after its been pulled together and then take some 2000g sandpaper or steel wool and "rebrush" the finish.

being a restaurant prep sink ,it's probably already warped or soon will be
