摘要： The invention concerns a hybrid arc-laser method for welding metal parts, such as a tube or tailored blanks by producing at least a weld joint between edges to be welded and by using a laser beam and an electric arc combined with each other so as to melt and subsequently solidify the metal along said edges to be welded. Said method consists in: (a) striking at least a pilot arc between an electrode and a hybrid welding head nozzle, said electrode being powered with electric current and being contacted with a first gas input in said hybrid welding head, said first gas having a gas composition capable of promoting sparking of the pilot arc; (b) transferring the thus sparked pilot arc to the edges of the part(s) to be welded; and (c) feeding said hybrid welding head with a second gas so as to obtain a protective gaseous atmosphere consisting of a mixture of the first gas and the second gas, said protective gaseous atmosphere being evacuated towards the welding zone by said hybrid welding head and protecting at least part of the welding zone during welding of the weld joint by combining the laser beam and the electric arc, the volume flow rate of the first gas (Q1) and the volume flow rate of the second gas (Q2) being adjusted such that: 0
