DUAL HEAT SOURCE HYBRID WELDING TORCH AND WELDING METHOD

WIPO Patent Application WO/2018/145543

A1

A dual heat source hybrid welding torch (3), comprising a consumable electrode and a non-consumable electrode; the axes of the two electrodes form an acute angle of smaller than 60 degrees; the consumable electrode and the non-consumable electrode respectively establish an electric arc with a workpiece, and a common molten pool is formed; the distance between the electric arc impact points of the two electric arcs on the plane of the workpiece is D; and the electric arcs are stabilized by means of an adjusting device for adjusting the distance between the two electrodes and a magnetic shielding piece for applying a transverse magnetic field between the two electrodes. Further disclosed are a manner for achieving a hybrid welding by using dual heat sources, a dual heat source hybrid welding system comprising the dual heat source hybrid welding torch, and a method for welding by using the dual heat source hybrid welding system. The use of the hybrid welding system comprising the dual heat source hybrid welding torch can, according to parameter conditions of the welding operation, reduce the affects of electromagnetic force on the electric arcs by means of the described adjusting device and reduce the affects of MIG electronic arcs on plasma electric arcs.
