Welding arrangement used for resistance welding processes comprises welding units connected to a supply unit for welding on welding points of a workpiece

摘要

Welding arrangement comprises welding units (14.1-14.n) connected to a supply unit (16) for welding on welding points (P1-Pn) of a workpiece (12). Each welding unit is assigned to the welding points. Each welding unit is controlled by power switches (T1-Tn). An Independent claim is also included for a welding process using the above welding arrangement. Preferred Features: The power switches are connected to a control unit (40). The welding units each have one electrode (44.1, 48.1) connected via lines to the outlets (42.1-42.n) of the supply unit The supply unit has an inverter (18), transformer (26) and/or rectifier (32).
