摘要： In a method of treating a nitrided/nitrocarburized workpiece, at least a portion of the workpiece is subjected to a first step in which at least one laser beam is moved in at least one pass over the portion, until the surface layer of the portion is transformed in part or in full, and until the distribution of the nitrogen concentration in the diffusion zone is modified. In a second step at least one laser beam is moved in at least one pass over said portion so as to enable the nitrogen concentration in the underlying diffusion layer to be reduced.

摘要： Welding systems including welding torch assemblies are provided. The welding torch assembly may include a welding torch adapted to be utilized in a welding operation to establish a welding arc between the welding torch and a workpiece. Shielding gas may be supplied to the welding torch for establishment of a gas shielding area around a weld pool. The welding torch assembly may also include a temperature sensing system having a non-contact temperature sensor coupled to the welding torch and adapted to sense a temperature of the workpiece at a location outside of the molten weld pool.

摘要： This TIG welding device has: a unit-type device main body (10) having a DC-type welding power supply circuit, a control circuit, and a variety of drive circuits, etc., housed therein; and a welding head (12) that performs TIG welding using a touch-start method, on a section to be welded in a base material upon an electrical component supporting body (S) under the supply and control of force from this device main body (10). In the welding head (12), a linear drive member (34) is joined via a raising/lowering support shaft (32) to a raising/lowering drive unit for a raising/lowering tower (30). A torch (22) and a clamp electrode (24) are vertically attached to this linear drive member (34) so as to be integrally movable and to be separable. As a result, high quality arc welding whereby two members (base materials) are held by a clamp and welded can stably and reliably occur

摘要： The invention relates to a process for cladding at least one portion of a metal part, the process implementing a non-consumable electrode, a consumable metal filler wire, and an electric arc drawn between the electrode and the part so as to produce a molten metal puddle, the end of the metal filler wire being melted by the electric arc so as to achieve a transfer of molten metal from the filler wire to the molten metal puddle and to coat at least one portion of the part with a metal deposit. According to the invention, the process uses a shielding gas to shield the electrode, the filler wire and the puddle, with a gas mixture containing 20 to 70% helium, and argon for the rest (% by volume).
