Metalworking production line sub-assemblies move through a series of beam welding heads operated sequentially by the same power supply unit

摘要

Claimed is a manufacturing process and manufacturing system for the production of a sub-assemblies consisting of several parts (1-3) at several production stations (32, 33). The sub assemblies advance through two or more beam welding stations powered in sequence by the same power supply unit. At the first production station (32) components (1-3b) are presented to a first beam welding station with a first welding head (121), where the components are clamped (111) together and welded. These components then advance (45) from which the welded group (122) is then transferred to a second production station (33), where it is brought together with a further group (1-3b) and advanced to a second beam welding head (146a). The two groups are clamped together and welded. The resulting component group (147) advances through a second transfer zone (129). The beam welding heads (121, 146a) are alternately powered from a single energy source (34).
