In the laser gas shielded welding technology, as the laser beam is emitted, two beams of gas shielded arc are also applied to the molten pool. The three tips are simultaneously integrated into an automatic welding head, and the additional welding arc The laser gas protection welding technology is essentially different from the traditional laser hybrid welding technology. There is fierce competition between laser welding technology and arc welding technology, and on the other hand, the combination of the two has innovative effects. In the so-called laser gas shielded welding technology, the combination of the two has higher welding efficiency and also saves costs. During the 2001 welding and cutting professional exhibition, Fronius demonstrated for the first time the practical and economical laser protection gas welding equipment. Since then, a total of 65 such welding equipment have been put into industrial applications for mass production in the automotive industry. In the manufacture of automobiles, these laser-shielded gas welding equipment are used for the welding of axles, doors and roof frames of aluminum alloys and steels. The maximum thickness of welded plates is up to 4 mm. Development of new laser gas shielded welding Fronius plans to put the laser and two welding electrode welding and cutting equipment on the market in 2009. The laser gas-shielded welding technology used in this series of equipment combines the advantages of laser welding and gas-shielded welding technology. The diversity and specific advantages of its application stem from the fact that the laser and gas shielded welding tips coexist in an automatic welding head, while the laser welding beam and the arc of the two gas shielded weldings act together in the weld pool of the weldment. The first welding test that combined laser welding and gas shielded welding dates back to the 1980s. But for 20 years, this technology has been in the laboratory, and has never taken the door of the laboratory. In this hybrid welding process, the laser beam and the protective arc are simultaneously applied to the weld of the weldment. The laser beam is deeply melted into the weldment with very high energy; the MSG gas shielded welding system continuously transports the weld material while emitting a welding arc to form a wide flat surface weld. This hybrid welding technology combines the advantages of laser welding (high welding speed, small weld heat affected area, deep weld seam) and gas shielded welding (very good weld joint capability, high weld strength and passability) The use of welding consumables, the ability to purposefully improve the quality of the weld). According to the application experience of laser gas shielded welding, users hope that the laser gas shielded welding equipment is more powerful, and the key point is to solve the welding of thick steel plates with better melting mode and faster welding speed. According to the process analysis and evaluation of the Fronius technicians, it is considered that the laser and the two-weld welding electrode are the best solution. In this solution, the most important problem is to integrate the laser tip and the two gas shielded welding tips into one of the smallest possible automated welding heads. The spacing between the laser welding beam and the arc should be as small as possible. (Figure 1). In addition to the welding technology factors, the size and kinetic performance of the welding head and the accessibility are all technical problems to be solved.
