Abstract

The geometry and microstructure of the seam can be influenced by changing technological parameters such as laser power, welding speed, focus distance and shielding gas. In this research we examine the effect of laser power and focus distance on the quality of the breaking torque value while the welding speed and the shielding gas is unchanged. From the test results, we found that changing the defocus has no effect; a change in laser power affects ~15 %, while a change in welding position significantly affects the breaking torque.
