Default Suggestion instead of welding

I was asked if I could weld up a crack in a stainless steel counter top in a house. I went and looked at it, and it is right in front of the sink, which is why the gentleman wants it welded, so water will not get below it to rot out the wood underneath. It looks like it was soldered originally, and the pieces pulled slightly apart, opening up the seam.

I tried a sample weld in my shop with my small welder, and I was having problems with the wood underneath gassing off/ and getting on fire, so I do not want to do this in the customers house. And, I think I would need to drag the bigger heavy welder, so I would have a variable amp pedal, to make it work.

I think my other options would be to try to resolder it, using an electric, or other old school solid iron.

Or does anyone else know of an epoxy that I could use instead, that would look good and stick to the stainless?

I think if I was to stick with the welding, I probably would have problems with the solder there already, unless I was to actually pull the sink and lift the counter up off the wood.

Virtually impossible to fix that in place. For one thing there's a gap between the two sides which would be very tough to fill. Whoever did the initial installation sure didn't do a good job--having a seam right there in front like that is pretty dumb. I think replacement of the whole counter top is the only way to go...

I agree with Keith.

Yup, dumb place for a seam... Weld in place, make some smoke, then squirt water up underneath to put the fire out. THAT water will dry eventually so I wouldn't worry too much about it.

Remove the sink and use a oscillating tool or something of the like to make a slot you can slide a backing strip in place.

I like Zach's suggestion of pulling the sink to get at it to put some kind of backing in. It depends on how much of a project you want.

Maybe you could slide a couple strips of metal backing in there as is. Clean the groove out and edges of countertop ready for welding. Maneuver the strips in there with a pick tool or awl. Cool with a damp rag after each pass although you may get warping and the sink may buckle. On second though, pull the sink...

Take a piece of SS the width of the sink and glue it on top wrap it down the front.
At least you will have two symmetrical lines and no gap.

I think I would try making clearance behind the steel and put a 316 backing
piece behind the crack, and weld the top piece to the backing piece, to create
a double lap weld, likely in 3 passes with plenty of time for cooling to minimize
warping.

Then find the moron who put the seam there in the first place and bitch slap
him.

Thanks for the suggestions fellows. I guess I will need to see how easy it will be to pull the sink.
