"HYBRID WELDING PROCESS USING A LASER BEAM COMBINED WITH AN ELECTRIC ARC AND SOLID SOLDER WIRE OR SOUL THAT CAN BE USED IN THIS PROCESS". Hybrid welding process using a laser beam combined with an electric arc, with a supply of consumable welding wire and shielding gas, in which the wire is fused by the laser beam and / or electric arc to produce a weld. on at least one piece of steel to be welded, characterized in that the weld contains 30 to 1,000 ppm titanium by weight, at least 0.7% manganese by weight, 50 to 1,000 ppm oxygen by weight and less than 10% nickel by weight. Solder wire that can be used in this process.
