VW Experts believe the company's materials: Compared with the pure laser Welding Electrode, laser hybrid welding of sheet metal parts can be greatly improved connectivity gap. So that the VW company can more fully utilize high-speed laser welding arc welding process stability. Another application example is the BMW 5 Series BMW aluminum partitions using this laser hybrid welding technology and high-pressure deformation processing of aluminum alloy frame welded together.
With a variety of laser welding technology alone compared to the laser hybrid welding technology has significant advantages. For the laser mixture, the advantage is mainly reflected in: a greater penetration / large gap welding capabilities; weld toughness better, by adding supplementary materials can be organized to exert influence on weld lattice; no burn-through when the weld on the back sagging phenomenon; applies more broadly; the help of laser technology investment less replacement. Inert gas to the laser MIG hybrid welding, the advantage is mainly reflected in: the higher the welding speed; fusion great depth; generate less heat welding; weld strength; weld width is small; weld protruding small. Making the production process of the whole system stability, availability of good equipment; weld seam welded for processing workload and the workload is small; welding and shorter, low cost, high efficiency; has good optical properties of device configuration .
However, laser hybrid welding in the power equipment investment costs are relatively high. With the further expansion of the market, the price of power supply will decline, and the laser hybrid welding technology in more applied areas. At least the laser hybrid welding technology in welding of aluminum alloy is a very suitable welding process, a longer period of time will become a major welding tools.
