<p>A hybrid welding method uses a laser beam in combination with an electric arc with a fusible filler wire and a protective gas. The filler wire is melted by the laser beam and/or the electric arc in a manner to produce a weld joint on at least one steel component to be welded. The weld joint contains (by wt) 30 to 1000 ppm of titanium, at least 0.7% of manganese, 50 to 1000 ppm of oxygen and less than 10% of nickel. An independent claim is also included for the welding wire used in the welding method.</p> |
