各种金属材料采用激光焊的可能性
发布时间：2015-11-23
脉冲激光焊主要用于微型件，精密元件和微电子元件的焊接。低功率脉冲激光焊常用于直径0.5mm以下金属丝与丝（或薄膜）之间的点焊，脉冲激光焊已成功地用于焊接不锈钢，铁镍合金，铁镍钻合金，铂、佬、钽、锯、钨，钼，铜及各类饲合金、金、银、铝硅丝等．脉冲激光焊可用于显像管电子抢的组装、按反应堆零件，仪表游丝，混合电路薄膜元件的导线连接等。用脉冲激光封装焊接继电器外壳，锂电池和但电容外壳，集成电路等都是很有效的方法。

由表可见，激光焊接可在许多类异种金属间进行，铜—镍、镍—钛、钛—钼、低碳钢—铜等异种金属在一定条件下均可进行激光焊。
连续激光焊主要用于犀扳谍熔焊，激光焊由于不受电子束焊真空室对零件的局限、无需在真空条件下进行焊接，故其应用前景更为广阔，尤其是激光焊设备常与机器人结合起来组成柔性加工系统，使激光焊的应用范围进一步扩大。
