摘要
In order to keep constant the welding rate of the welding rate change which occurs particularly in claddings and multi-layer all-around welds a height path-measuring measured value converter (34) is assigned to the torch height control device (33), whose output signal is passed to the travelling mechanism control (35) for the travelling speed correction. In the preferred use in orbital welders with a rotating travelling mechanism (13), a simple and inexpensive maintenance of a constant welding speed in all-around weld seams whose length changes during welding is made possible by the arrangement of a height path-measuring measured value converter (34).
