Abstract:
The invention relates to a method for joining of at least two materials, non-weldable directly to each other with thermal joining processes in a lap joint configuration, where a two step sequence is used consisting of a first step to apply a thermomechanical or mechanical surface protection layer on the surface of a (stainless) steel substrate (1) and a second step where, a thermal joining process is used to weld the sprayed layer (2) with an applied aluminum sheet (3) without having brittle intermetallic phases in the whole material configuration.
Abstract:
본 발명은 프로젝션 용접 장치에 관한 것으로, 레이저를 이용한 거리센서 및 그와 연동하는 릴레이 연결 구조로 인해 하부 전극부의 작업 환경이 정상인 경우에만 너트 피더의 너트 공급부와 상부 홀더의 실린더 구동부를 구동하도록 구현됨으로써, 하부 전극부에 이물질(특히, 작업자의 손)이 있거나 또한 너트(nut)의 안착 자세가 불량한 상태에서 장치가 구동되지 않은 효과가 있다.
Abstract:
An apparatus and method for fastening layers of non-ferrous alloys, like aluminum, magnesium and copper utilizes a steel fastener and a spot welding machine. The fastener and metals are stacked and the heat from the welder's electric current softens the lower melting point aluminum allowing the fastener to penetrate the aluminum. A weld zone between the fastener and the various layers creates an internal weld. The fastener has a rough shaft that is coated by the molten weld zone and is hard to withdraw on solidification. Layers of non-conductive materials like plastics and ceramics may also be affixed to a conductive layer using a fastener made from a compatible material that extends through a pilot hole and welds to or penetrates a conductive layer. The fastener may have projections that initially reduce contact area with the stack.
