    摘要: The invention concerns a method of welding two metal parts together. The first part and the second part are made of metal or metal alloys and the reflectivity of the first part is lower than or equal to the reflectivity of the second part. Typically the first part is made of brass and the second part is made of copper. In the common welding zone, the less reflective part covers the most reflective part, so the laser beam is directed only against the less reflective part. The advantage of this is that the laser beam is not directly in contact with the high reflective part so less energy is reflected away from the welding zone.
