How can galvanized sheet be welded with copper plate spot welding machine?
The second section with larger current welding on the base metal, the cylinder pressure is larger than the pressure to the same specifications of the soldering iron, if appropriate parameters can be welded joint strength is high, and the service life of the electrode is also good.
Specifically, the first paragraph uses a small current soft standard way to melt and extrude the zinc coating on the plate surface to reveal the parent material inside
Galvanized sheet plating on the surface of a layer of zinc, so the general use of welding in the two part of the way to discharge welding
