  • Single-pass laser welding method of a T assembly of metallic parts
    Patent number: 7071445
    Abstract: The method is used to attach the various parts of a “T” assembly using a single laser welding pass from the outside of the “T” assembly. Welding is done with a bifocal welding head (20) the two axes (21) of which are parallel to a surface of the part forming the “T” stem (10), the weld being made along the entire length of the assembly. To be used when manufacturing vanes for a turbo jet fan duct.

  • Welding tool
    Publication number: 20060081562
    Abstract: A welding tool in particular for TIG arc welding or plasma welding or laser welding includes means for feeding an inert gas to the head of the tool, and means for confining the protective gas around the welding head, the confinement means comprising a skirt prefabricated out of semirigid refractory material and means for releasably fastening the skirt on the welding head.
