Lasers in industrial processes has been maturing, the entire large processing technology is still groping. Laser applications in various industries to change the conventional technology. In particular, fiber laser technology applications in the automotive sector will promote the development of the automotive industry and beyond. If you want to buy a 14-20 seat has a large commercial vehicles, users should be what is most important? Stylish appearance, or luxurious interiors? For a large-scale high-end commercial vehicles, these are just icing on the cake, the only really important one, that is safe, "35 meters of laser welding, weaving the most solid body." The only luxury brand in the large commercial vehicle segment, Mercedes-Benz Sprinter, in terms of safety and created a number of models in the same level of the first, called the "safest in the history" of large commercial vehicles.

35m laser welding, weaving the most solid body

Speaking of laser welding technology, I believe you no stranger to fans. To improve the safety performance of vehicles, the laser welding is a revolutionary technology. Compared to conventional resistance welding, laser welding can be achieved on the one hand continuous welding, on the other hand does not change because of high stability and strength of the metal being welded. May look simple analogy, traditional resistance spot welding is like buttons, although the clothes can also be linked together, but its point of attachment is discontinuous separation of relatively sparse, and laser welding is like a sewing machine to sew fabric together, close the connection point will be very strong.

Benz Sprinter is not only the same level models only models using laser welding, laser welding and reached a total cumulative length of 35 meters. Linear laser welding mainly in the underbody, side panels and roof joints, not only can increase the body's fatigue resistance, impact resistance and corrosion resistance, but also the sealing body has greatly improved, Linear makes the whole body becomes seamless. In addition to providing security guarantees, the laser welding also enables Sprinter appearance more beautiful, smooth and soft welds greatly enhance the visual effect of a streamlined vehicle.

This means that the "history of the most secure" large commercial vehicles Mercedes Sprinter even encounter violent impact, this monster can keep the body intact, reducing distortion from the impact. When the unexpected inevitably occur, Linear able to reduce losses to a minimum.

Summary

Laser welding is the use of high energy density of the laser beam as an efficient method for precision welding heat source. Laser welding is one of the important aspects of laser material processing technology applications. 1970 is mainly used for welding of thin-walled material and low-speed welding, welding process is hot conduction type, that laser radiation heating the surface, the surface of the heat through the heat transfer based internal diffusion, by controlling the laser pulse width, energy, peak power and repetition rate and other parameters, so that the workpiece to melt to form a specific pool. Because of its unique advantages, it has been successfully applied to micro, small parts precision welding.
