Hybrid laser beam-electric arc welding of aluminium or aluminium alloy components, especially for the fabrication of motor vehicle and aircraft elements

摘要

Aluminium or aluminium alloy components are welded by the combined action of a laser beam and an electric arc generated by a non-fusible electrode. The laser beam and the electric arc are generated, delivered and/or oriented in a manner such that the electric arc may be in front of the laser beam.
