Fronius company in 2009, and two laser Welding Electrode welding, cutting equipment market. The equipment used in gas laser welding technology combines laser welding and gas welding two kinds of welding technology advantages. Diversity and its application-specific benefits from the laser and arc welding nozzle were living in an automatic welding head, the same laser beam welding and gas welding of two arc welding parts together in the pool.

The first laser welding and gas welding together of the welding test can be traced back to the 1980s. But 20 years, this technology has been hovering in the laboratory, the laboratory has not taken the door. In the hybrid welding process technology, the laser beam and arc welding arc while welding pieces of acting on the welds. High energy laser beam to melt the solder pieces deep inside; MSG welding gas arc welding system is given, while in the continuous transmission welding, forming a wide flat surface of the weld. This compound combines laser welding welding technology advantages (high-speed welding, heat affected zone is small, the weld depth) with the advantages of gas welding (weld good connectivity, high weld strength and can be the use of welding, weld quality have improved the ability of the destination).

Application of the laser gas welding experience, users want to laser gas welding equipment and more powerful, the focus is to address the thick steel plate welding, better and faster way of melting the welding speed. According to Fronius's technical staff to use process analysis and evaluation, that the laser welding together two composite welding electrode is the best solution. In this scenario, the main problem is: the laser nozzle and two gas welding nozzle as small as possible in a single automated welding head, the laser beam and arc welding should be as small as possible distance between (Figure 1). In addition to factors of Copper Welding Electrode technology, welding head size and movement performance, close to the performance are needed to solve technical problems.
