Arc welding system, and arc welding method using such a system

Abstract

An arc welding system (1) for welding two parts (P) together has at least one base (2) movable relative to the surface of one of the parts (P) to be welded in a direction of travel (D). A torch support (6) is arranged to receive an arc welding torch (T) being of the type employing a wire electrode (F). A first actuator (10) and a second actuator (11) are provided for moving the support (6) relative to the base (2) in a plane (Pt) substantially transverse to the direction of travel (D) of the base (2) relative to the parts (P) and in two different directions, each non-parallel to the longitudinal axis (L) of the torch. A control unit (20) is configured to control the first and second actuators (10, 11) in a coordinated manner as a function of the trajectory to be imparted to an end (30) of the wire electrode (F).
