摘要: One of the drawbacks laser welding is distortion welded bodies that closely linked with generation and redistribution residual stresses in vicinity weld. In this contribution, mapping surface macroscopic grain sizes was performed for several welds created beam various speeds. Larger distortions are exhibited by samples manufactured higher speed, which also exhibit substantial compressive perpendicularly to axis.
