Use of the Laser-TIG hybrid method in the automotive industry

High demands are placed on the joining of body parts in terms of strength and consistent quality. Simultaneously, production time minimizing is required. In addition to the most common spot resistance welding, laser welding is often used. This provides high welding speed as well as good strength. Of course, there is a general desire to increase the overall strength of the body-in-white while reducing production costs, which are conflicting requirements. The only way forward is to use modern steel materials (HSLA steels, DP steels, etc.) and to use new, more advanced joining technologies. The paper presents possibilities of hybrid Laser-TIG welding technology
