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 tip, 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.
