It is undoubtedly an effective method to solve the problem of improving the safety of the automobile structure and reducing the weight of the vehicle by welding together the plates of different thicknesses and different strengths and punching out the laser-welded plate technology of the whole component at a time.

The automotive industry has been working to reduce the weight of the car without reducing the structural stability of the car. Laser tailor welding technology has become one of the successful new technologies, achieving the goal of improving the safety of the car structure while reducing the weight of the car. At present, laser tailor welding technology has been widely used in structural members such as automobile longitudinal beams, insurance rafts, door panels and floors.

Traditional stamping process

The so-called laser tailor welding technique is a technique in which two or more materials having the same thickness or different thicknesses are joined and reshaped before press forming. The technology originated in the 1980s. At that time, it was mainly to solve the problem that the steel plate width of the rolling mill was insufficient, and the tailoring technology was used to meet the needs of the automotive industry for wide plates. Welding is the main. With the development of the automobile industry, the laser tailor-welded plate is developed in the direction of the poor thick plate, and the steel plates of different thicknesses can be tailor welded. At this time, the purpose of laser welding of the automobile steel plate is truly realized.

Under the traditional process conditions, the manufacture of various parts of the automobile is made by spot welding of various small stamping parts. After adopting the new technology of laser tailor welding, it is changed to first punch and weld the plates of different strengths and thicknesses into a whole blank, and then perform integral stamping.

Microscope Slides

The East-West glass slide is a glass slide or quartz slide that is used to place a glass slide or quartz slide when it is observed under a microscope. During production, a cell or a sample containing a certain tissue is randomly placed on the slide glass, and a cover slip is placed on it for observation a similar material that produces a phase difference.
