Tailor welded plate in the automotive manufacturing industry has been widely used. Tailored welding is the welding of steel plates of different thickness, material and surface conditions using laser welding equipment, stamping and manufacturing into parts to meet the different requirements of material properties and thickness. The application, advantages and manufacturing process of laser welding plate welding technology are introduced. The application of laser welding welding plate technology realizes the purpose of reducing body mass, increasing body rigidity, reducing the number of body parts assembly, improving assembly precision and reducing vehicle manufacturing cost.
Automotive manufacturing is currently the largest use of laser welding technology industry,from auto parts production to the body manufacturing,laser welding has become one of the important welding methods in the automotive manufacturing.Tailored welding is the different surface coating,material and thickness of two or more plates by laser welding spliced together into rough parts .and then stamping in the automotive manufacturing parts. Due to its freedom of combination, different seeel plates can be spliced together as the main application of laser welding in automobile body manufacturing, which can reduce the body quality, increase the rigidity of bodywork, reduce the number of body parts assembly, improve assembly precision and reduce the number of cars The purpose of manufacturing costs.

Application advantages of laser welding plate
1.The application of laser tailor-welded blanket in automotive products effectively improves the performance of the vehicle and has significant advantages in reducing the manufacturing cost. The use of laser welding tailgating board and traditional components compared to the manufacturing process, its advantages.
2.To verify the structural performance of the product, a crash test was performed on a laser tailor welded plate stamped into U-shaped beams by three steel plates of different strengths. Requires collision at both ends of the collapse of energy absorption, the middle to maintain the original shape. It can be seen that after the collision, both sides of the collision are crushed to absorb the impact energy according to the design requirements, with no deformation in the middle.
