Abstract

Welding current is fed, at least for one of the coated sheets, indirectly to the point to be welded by means of the sheet surface in order that an external layer remains intact and a contact established between the surfaces which have been uncovered for welding. Annular or linear edges and depressions are formed at the welding point in the sheet or on the intermediate welding pieces with the aid of stamps and/or cutting. Overcomes drawbacks encountered with conventional prior art welding machines where the outer layers of the welded sheets are destroyed by uncovering or by the fusion caused by the electrodes. Use: welding metal sheeting or elements coated with synthetic material, varnish or some other substance, such as steel, chrome-nickel steel, aluminium (anodised) or other metals.
