The change from arc shape to crescent shape at the bottom of cross section of dissimilar metal K418 and 42CrMo is observed with the proportion of laser irradiation on K418 to 42CrMo altered from 1/3 to 2/3, which is due to difference of theirs physical and chemical properties.
由于K418和42CrMo热物性参数的差异,K418与42CrMo异种金属激光焊接随激光覆盖K418侧的光斑面积比例从1/3增加到2/3,大钉头小钉身的焊缝横截面尾部从圆弧形逐步过渡到月牙形。
