H. Wang, Changchun Railway Vehicles Co. Ltd, China
Abstract:
With so many advantages, such as lightweight, antirust, low cost of maintenance and simple manufacturing process, the production of high-level stainless steel railway vehicles has become the development strategy of European, American and other developed nations. High-quality surface state and structure strength can be achieved by the partial penetration lap laser welding of the side panel structure. Laser welding will be the new technology for the manufacture of railway vehicles. The laser welding process, influence of laser welding parameters on the surface and strength, the heat source model of lap laser welding, methods ...
