Abstract

The invention relates to a method for controlling and/or adjusting a welding process, using a melting welding wire (13), wherein after ignition of an electric arc, a welding process is carried out , said welding process being adjusted on the basis of several different welding parameters and being controlled or adjusted by a control device and/or a welding current source. In order to determine the position or distance between the end of the welding wire (13) and the workpiece (16), which is to be processed, in a manner which is as accurate as possible, at least one mechanical adjustment process (41) is carried out during the welding process, enabling the position of said welding wire (13) to be determined, said welding wire (13) being used as a sensor.

Description

technical field [0001] The invention relates to a method for controlling a welding process, wherein after ignition of the arc, a welding process is carried out which is adjusted on the basis of several different welding parameters and controlled by a control device and / or a welding power source. Background technique [0002] Patent Publication EP0774317B1 discloses a pulsed arc welding method for alternately supplying a pulse current and a base current through a consumable electrode and a base metal, respectively. In this method, the length of the arc is controlled in such a way that the average or cumulative value over time corresponds to a set value. The base current decreases with a higher time-averaged or accumulated value and increases with a smaller value. In addition, the supply time of the pulse and base currents can be decreased or increased according to the measured length of the arc. Typically, the length of the arc and thus the distance between the wire end and...
