摘　　要：对厚0.3mm镍合金薄板拼焊进行精确定位、对位和夹紧,针对合金薄板在激光拼焊接过程中易变形及发生错位的特点,设计了特殊的夹具,获得平整的焊缝外观。并且通过在夹具内部设置气槽,使得在焊接过程中对焊缝的背面及正面同时进行气体保护,获得美观的焊缝。Because the 0.3 mm thick nickel alloy sheet is easy to deform and appear dislocation during the process of laser welding,a special loading fixture is designed to make sure its accurate positioning,counterpoint and clamp,and the design can prevent dislocation and efficiently reduce the influence of the joint gap so that a flat appearance can be achieved.Setting a gas tank in the fixture can protect air both in the weld＇s front and back,which can form good-looking welding seam.
