Process for welding a metal layer to a metal object involves using a laser to heat the bonding zone, and controlling the welding temperature by using a pyrometer

摘要

To weld a metal layer (16) to a metal object (12), a laser (14) applies heat to the bonding zone (18) through the side of the object away from the metal layer and towards it. A pyrometer (20) monitors the metal layer temperature to control the welding action.
