    摘要: A welding mask for ultrasonic welding has a part positioning window that receives a first metallic part that is ultrasonically welded to a second metallic part. The mask is engaged with a top surface of the second part and the first part is then placed in the window with its lower surface engaging an upper surface of the second part. The first part is then engaged by ultrasonic welding apparatus which vibrates it and causes it to be welded to the second part. The internal walls defining the window are comprised of a first portion having parallel surfaces which can contact the edges of the first part. Extending from the first portion to the lower surface of the mask is a slanted or chamfered surface that slants away from the edges of the first part and does not contact the edges of the first part. The purpose of the chamfered surface is to prevent the first part from becoming adhered to the welding mask during ultrasonic welding.
