Mobile or stationary welding system

Abstract

The invention relates to a mobile or stationary welding system (1) for welding a first metal part (R1) with a second metal part (R2) by butt flash welding, said welding system (1) comprising at least two electrical flash contact blocks (17, 19) configured to allow the passage of a single-phase alternating current; a direct current electrical power generation system (30) configured to supply a direct current;and an electrical power conversion system (40) comprising an inverter (41), said inverter (41) being disposed between the electrical power generation system (30) and said at least two sparking electrical contact blocks (17, 19) and being configured to convert the direct current supplied by the electrical power generation system (30) into a single-phase alternating current, said single-phase alternating current directly or indirectly supplying said at least two sparking electrical contact blocks (17, 19).
