Abstract

A method of and apparatus for welding sheet steel panels by submerged arc welding is described. By providing one or, depending on the thickness of the sheet steel panels, more than one pair of closely spaced wire electrodes in the weld gap with the simultaneous introduction of additional filler metal carrying no current, preferably in the form of a metal powder, disadvantages associated with known methods may be avoided.
