Method and device for combined laser-arc welding with control of laser unit according to welding torch

摘要

A method for combined laser-arc welding and a device for combined laser-arc welding uses a device for controlling a laser unit for producing a laser beam according to a welding torch for producing an arc in order to optimize the energy balance and to adapt the combined laser-arc welding process to the respective conditions. The device for controlling the laser unit is connected with a detector that detects the arc voltage or the arc current. The laser output is adapted to the arc output and is controlled by a closed control circuit.
