The invention relates to a laser beam welding method with fusible welding wire and shielding gas, in which said wire is melted by said laser beam so as to produce a solder joint on at least one piece of steel. soldering, preferably the piece or parts are made of ferritic steel, characterized in that said solder joint contains from 30 to 1000 ppm by weight of titanium, at least 0.7% by weight of manganese, from 50 to 1000 ppm by weight of oxygen and less than 10% nickel. Welding wire that can be used with this process. |
