The ultra-thin plate (thickness <0.1 mm) is widely used as the raster plate in the high-precision collimator, but the welding induced distortion is the main problem restricting its application. In this study, the effect of laser power on the welding deformation of an ultra-thin steel plate during pulsed laser welding was studied by means of both numerical simulation and experiment. A three dimensional thermal-elastic-plastic FE analysis was conducted to predict the temperature field and distortion of the ultra-thin steel plate. The thermal and mechanical material properties used in this simulation all followed the non-linear relations as a function of temperatures. Meanwhile, a pulsed laser welding experiment was carried out, the temperature field was measured by a pyrometer, and the distortion was measured by a laser displacement sensor. The results showed that the model prediction was consistent with the experimental measurements results.
