激光束焊接方法和设备
摘要：
当彼此重叠的钢板(W1、W2)被保持机构(12)定位和保持时，将第一激光束(L1)施加到钢板(W1)的加热区域(P1)以将钢板(W1)与其他钢板(W2)隔开给定距离，将第二激光束(L2)施加到焊接区域(P2)以焊接钢板(W1、W2)，并且沿焊接方向使第二激光束(L2)与第一激光束(L1)同时移动。将第一激光束(L1)所施加的热量、第一激光束(L1)的移动速度以及第一激光束(L1)的焦斑直径设定为可将所述第一激光束(L1)所照射的板(W1)保持在未熔化的状态并使得所述板(W1)塑性变形。
摘要（英）：

While steel sheets (W1, W2) are positioned and held by a holding mechanism (12), a first laser beam (L1) is applied to a heating region (P1) of the steel sheet (W1) to space the steel sheet (W1) from the other steel sheet (W2) by a predetermined distance. A second laser beam (L2) is applied to a welding region (P2) to weld the steel sheets (W1, W2). An amount of heat applied by the first laser beam (L1), a moving speed of the first laser beam (L1), and a focused spot diameter of the first laser beam (L1) are set to keep the sheet (W1) irradiated with the first laser beam (L1) in an unmelted state and plastically deform the sheet (W1).
