摘要： A method for forming a smooth interface between a weld cap and an adjacent base metal utilizing ultrasonic impact treatment. The method improves the geometric profile of a weld while imparting a compressive residual stress layer on the weld metal and base metal thereby alleviating the tensile residual stresses imparted to the metals during welding. The contouring process does not remove material, as in grinding, but plastically deforms the surface being treated producing a densified surface, in turn providing a smooth weld cap and base metal surface finish without the loss of base or weld metal thickness.

摘要翻译： 一种利用超声波冲击处理在焊接帽和相邻的母材之间形成平滑界面的方法。 该方法改善了焊缝的几何形状，同时在焊接金属和母材上施加压缩残余应力层，从而减轻了焊接过程中赋予金属的拉伸残余应力。 轮廓加工过程不像研磨一样去除材料，而是使待处理的表面发生塑性变形，产生致密的表面，从而提供平滑的焊接帽和贱金属表面光洁度，而不会损失基体或焊接金属厚度。
