USING A TI G
THE two pieces can be fitted flush; the tighter the better. With both sides clean, a few tack welds are placed to hold the metal in position. The join can now be fuse-welded from one end to the other. A consistent metal pool that can be ‘pushed’ along the join is required here. If you flip the piece and can still see the edges of the join, there wasn’t enough heat. Welding in one run will cause distortion, but that’s okay; a common misconception is that the heat has buckled the surrounding metal, but actually the weld is pulling everything in around it, causing it to warp. Using a hammer and dolly (or similar) along the weld, the tension can be released, letting the surrounding metal return to its original position while flattening out the piece.
