I thought I would have known an obvious answer to this, ie 'welded'; but I've just obtained an old spare tank for my MW which is full of crud. To make it servicable I was considering cutting the end off, getting the inside bead blasted and then welding the end back on. Pretty straightforward I thought. However upon looking at the end, which is recessed in slightly, it does not appear to be an obvious weld joining the pieces together. Not gas, not electric nor some version of spot welding I'm not familiar with. Just a damn good fit. Removing the paint on a section hasn't made it any more obvious. Anyone know if these are soldered together, as this seems the only obvious method which wouldnt leave a trace of 'heated' metal? I would have thought brazing would have introduced too much heat and deformed the parts too much. So before I start cutting, anyone know if this might this unsolder?
