METHOD OF SPOT ARC WELDING OF A HIGHLY CORROSION RESISTANT COATED SHEET TO A METALLIC SUPPORTING BODY

摘要

The invention relates to the spot fixing of a highly corrosion-resistant overlay plate to a less corrision-resistant workpiece and provides for the highly corrosion-resistant overlay plate to be provided with holes and to be connected at the same time to the steel workpiece by a first build-up weld in the holes. The first weld run is then covered by a second build-up weld. The build-up welding is carried out by means of inert-gas metal-arc welding with wire electrode. ……
