Abstract

A method of locating, by means of a sensor (13), the welding starting point in continuous bead welding operations to produce butt joints (1) in a workpiece (3) by means of the welding head (12) of an arc-welding apparatus, the method comprising moving the sensor towards the joint and lowering the welding head towards the surface (19) of the workpiece from a predetermined initial position externally of the joint, whereupon the welding head is moved towards the joint until the sensor detects the latter, whereupon the sensor determines the centre line of the joint and the welding head is set with respect to the latter to be finally lowered into the welding position.
