In the laser gas shielded Cast Iron Welding Electrode techniques, as the laser beam is emitted at the same time there are two beams of gas shielded arc welding arc acting on the molten bath, three welding nozzle integrated in an automatic welding of the welding head, the additional welding arc of the laser gas protection welding technology with traditional laser hybrid welding technology with the essence of the difference.

Laser welding and arc welding technology has a fierce competition on the one hand, the other hand, the combination between the two and innovative. In the so-called laser gas shielded welding techniques, the combination of the two having a higher welding efficiency, but also the cost savings. , Fronius welding and cutting during the professional exhibitions in 2001 for the first time shows the the practical economics laser protection gas welding equipment. Since then, a total of 65 sets of welding equipment into the automobile industry's mass production of industrial application. In car manufacturing, these laser protective gas welding equipment for welding of aluminum alloy and steel axles, doors and roof frame structure, the largest welding sheet thickness up to 4mm.

R & D of new laser gas shielded arc welding

Fronius company plans in 2009, the laser and two shielded welding electrode welding, cutting equipment market. This series of equipment used in the laser gas shielded welding technology combines the advantages of the two welding laser welding and gas-shielded welding technology. The diversity of applications and the specific advantages from the laser and gas metal arcTungsten Welding Electrodestip of living in an automatic welding head, laser welding beam and two gas shielded welding arc interaction in the bath of the weldment.

The first laser welding and gas metal arc welding fusion welding test can be traced back to the 1980s. However, the past 20 years, this technology has been hovering in the lab, never taken to the door of the laboratory. In this composite welding technology, laser beam and the the protective arc welding simultaneously at the weld of the welding member. Laser beam at very high energy deep melting the weldment internal; continuous conveyor the MSG gas shielded welding system issued by the welding arc welding consumables, to form a wide flat surface weld. This hybrid welding technology combines the advantages of laser welding (welding speed, weld heat affected zone, weld depth) and gas shielded arc welding advantages (good weld connection ability, high weld strength and can use of welding consumables, ability of the destination to improve weld quality).

Based on the laser gas shielded arc welding application experience, users hope the laser gas shielded arc welding equipment is more powerful, the focus is to solve the welding of thick steel plate, there is a better way of melting and faster welding speed. Process analysis and use of evaluation based on the Fronius technical personnel, that the laser plus two protective composite welding electrode welding technology is the best solution. In this scenario, the most important question is: will the laser tip with two gas shielded arc welding tip as small as possible automated welding head should be as small as possible, the spacing between the laser welding beam and arc integrated . In addition to the factors of the welding technique, the size and movement of the welding head performance, accessibility performance is the need to solve the technical problems.
