In comparison with arc welding the laser welds differ e.g. in the intensity and distribution of residual stresses. Therefore the problems of these stresses, fatigue strength and operational reliability will be studied. Specifically the use of 3,5 kW power laser with fiber optics for welding sheets made from steel and high strength materials with or without additional material at a robotized workplace."@en . . . .
