This time I would speak the score of the pieces, which can be a trick though, is itself a technical working for some interesting and others just a technical learned and daily routine. Tapping:
Before welding itself, you must prepare the two sheets to be joined if they are to overlap, and create a root cord must separate approximately half the thickness of electrode with which it is soft soldering also vary according to the thickness of the pieces. In this case we are talking about no more than between 3 and 6 mm as if it is thicker, the preparation will vary.
initial
One trick is to place a rod tails between the two parts together thereby creating a gap for the cord that crosses root.
join the two pieces spot welding points that separated later. Put small enough points in the center and then at the ends of the board to melt, then the cord. If not punteáramos, going soldering and current tensions are opening parts in advanced and we could not keep the measure of union.
