ThyssenKrupp Tailored Blanks Ltd. Since 1985, production welded blanks, laser welding technology makes the car manufacturing emerged from the vehicle manufacturers to transfer material suppliers. Currently, laser Welding Electrode plate mainly used in automobile manufacturing. In laser welding, the material is docking rather than overlapping, which will bring the following weld characteristics:

(1) reduce the volume of the weld area, for example, welding width of not more than 0.5 ~ 1mm;
(2) does not increase the height of the weld;
(3) little effect on the performance of metal forming;
(4) attached to zinc in the weld, may maintain its cathodic protection;
(5) welding process, the heat affected zone is small.

After completion of welding, welding on the static and dynamic strength is a very important indicator, therefore, need to weld area sampling, the destructive tensile strength test (cupping test) to test the weld zone of the stretch forming performance. In general, the tensile strength of the weld strength than the base metal is higher.

Tailored blanks lap spot welding process and the traditional craft has many advantages compared to the product: not only reduces the cost of vehicle manufacturing, logistics costs, vehicle weight, assembly tolerance, rate of fuel consumption and waste, and reduce the external reinforcement the number of steps and simplified assembly process, while the collision the vehicle capacity enhancement, and the corrosion rate of metal forming ability increased. In addition, avoid the use of sealants, but also for environmental benefits.
