Laser-assisted GMAW (MAG/MIG/TIG)
During laser-guided and stabilized arc welding, the working point of the arc is stabilized by the laser beam. Hence, the welding seams are both robust and of high quality, even at high welding speeds. The arc can be guided precisely and flexibly by the laser beam.

For laser-guided and stabilized arc welding, the arc welding process (MAG/MIG/WIG) is stabilized by a laser beam with a low average output power of <400 W. Since the electrical arc can be guided using the laser beam, the energy can easily be focused into the parts to be joined. Using this process, it is possible to join difficult seam geometries, for example fillet seams.
The group “Machines and Controls” offers feasibility studies to examine whether customer-specific processes can be optimized using laser-assisted arc welding. This laser-based process can increase the welding speed, minimize the workpiece distortion and improve the process safety.
At the LZH, metallographic studies can be used to examine the quality of the process. Also, the group can integrate the welding process at the project partner’s premises.
