I recently purchased a 3-gallon Challenger VI keg that has a hairline crack near the lid. It has created a small leak. I talked to a friend who welds stainless and he said the metal was too thin to weld by hand. I suspect he simply doesn't have the skill since he mostly worked on heavy stainless for the oilfields. Would I be best off using lead-free solder to try to fix the leak or does it really need to be welded? I wouldn't worry about it for a 5-gallon, but the 3-gallons cost a fortune and I am really pissed about the crap deal I got on ebay. No returns!
I'd like to save this keg if I can.
