Abstract
A method of welding at least two metal sheets protected by a zinc coating that has a low vaporizing temperature. The metal sheets are placed on top of each other in such a manner that at least one metal sheet has a curved section beginning at the weld area. The weld is performed partly on the metal sheets in contact and partly at the separation between the metal sheets in order to allow gases generated by vaporization of the protective material to escape from the weld area.
