Abstract

In a method for automatic multi-layer welding of a joint formed by two joint surfaces according to which method the contour of the joint in a number of cross-sections is established by means of a sensor emitting signals representative of the contour of the current cross-section of the joint. After evaluation, said signals control the deposition of the weld beads by means of a continuously fed electrode which is directed towards a welding zone in the joint.
