Assembling sedentary part useful for anchoring wheel of vehicle, comprises solidarizing first and second sheets, while inducing selected zones of local matter fusions in shape of narrow cords by laser welding at distance from offsite faces

摘要

The method comprises placing one of inner faces (FI1-FI2) of a first sheet (T1) and a second sheet (T2) of a sedentary part (PS) in front of the other inner faces, and solidarizing the first and second sheets while inducing selected zones of local matter fusions in a shape of narrow cords by laser welding at a distance from offsite faces (FE1, FE2). One of the inner faces is provided with a protection coating. The placing step is performed by spacing the inner faces at a distance chosen on a level of the selected zones. The method comprises placing one of inner faces (FI1-FI2) of a first sheet (T1) and a second sheet (T2) of a sedentary part (PS) in front of the other inner faces, and solidarizing the first and second sheets while inducing selected zones of local matter fusions in a shape of narrow cords by laser welding at a distance from offsite faces (FE1, FE2). One of the inner faces is provided with a protection coating. The placing step is performed by spacing the inner faces at a distance chosen on a level of the selected zones. The distance between the inner faces on the level of the selected zones is 0.1-0.6 mm. The shape of the narrow cords comprises a straight line, a C-shape and a line presenting an undulation. The cords have an average width of 1 mm. The laser welding is carried out at a distance of 50-70 cm from the offsite faces. The solidarizing step utilizes a power laser of neodymium-doped yttrium aluminum garnet type to carry out the laser welding.
