Double focus laser welding technology Dr. Eva Schwinghammer, Chief Representative of Shanghai Representative Office of Trumpf Huajia Co., Ltd., introduced TRUMPF's HL 4006D The so-called standardization can only achieve standardization of the laser cable interface. The prerequisite for this step is the warranty and warranty, the three-package responsibility and the three-pack process are explained and approved. On the other hand, the spokesperson also agreed that the development trend of laser performance is constantly improving in various fields of laser application technology. This trend can increase the power of the laser and improve the beam quality of the laser. With the help of new laser generation solutions and new laser equipment designs, as well as new laser technology applications, this trend can be realized in the near future.

According to experts from BMW, BMW used double-focus laser welding technology when welding separators. Because this technology has good performance in the welding process of aluminum alloy materials, it is widely used in the mass production process of BMW.
In laser welding, the bifocal laser welding technique can form two focusing points with small spacing on the material to be welded, which can realize beam splitting and superposition of the laser beam. The superposition of two laser sources forms a laser beam that greatly increases laser power, production stability, product quality and production flexibility. On the one hand, the improvement of laser welding power can improve the depth of laser welding welds; on the other hand, it can improve the welding speed of laser welding; at the same time, it can avoid welding defects such as melting holes and burn-through which are common in aluminum alloy welding.
Standardization laser welding technique
From the perspective of the user of laser welding technology, a problem that has not been completely solved is the standardization of laser welding technology. This problem is concentrated in the connection interface of the equipment and the different welding equipment components. Experts at BMW pointed out that standardization will simplify the production and manufacture of laser optical equipment and components worldwide. VW's experts are similar to BMW's experts and believe that standardization can also increase the effectiveness of laser equipment.
Conversely, a spokesperson for Trumpf Gesch ftsbereichs Lasertechnik believes that there are new advances in laser technology every year. Therefore, there is a very strong competition among the manufacturers of laser equipment, which naturally hinders the development of products for the development and development of different laser technology equipment. 
Advanced lasers and welding systems (output power 350W~4000W) have been used in the manufacture of Chinese automobiles and parts.
