At the same time, to optimize the steel and aluminum by pre cut laser module consumption, thereby reducing the cost. However, the most important advantage of tailor welded plate according to local specific requirements for components selection of high strength steel or metal plates with different thickness, so as to achieve the purpose of weight loss. Due to weight loss and reduce the consumption of materials complement each other. The vehicle safety and efficiency also improved.
When the production of TWBs, laser module laser welding mainly used butt weld, which can achieve optimal power transfer and forming characteristics of the ideal. Therefore, the use of laser diode is required in this process, the solid laser or CO2 laser.
Select a new type of laser module is the first step of renewal and development. In the solid state laser, diode pumped thin disk laser and fiber laser are also considered that the two kinds of laser welding in the field of application has been approved, and has the efficiency of 30%.
First of all, laser module is the most favored choice is mainly based on their experience early. But then decided not to use fiber laser has been tested, but in favor of the fiber coupled diode laser.
