Hybrid electric arc0 / laser welding process, especially for welding tubes or motor vehicle components

摘要

"HYBRID WELDING PROCESS WITH ELECTRIC ARC / LASER, ESPECIALLY FOR WELDING TUBES OR MOTOR VEHICLE COMPONENTS". Hybrid welding process and unit for welding metal parts, such as custom-made blanks, using a laser beam and an electric arc, preferably a plasma arc, in which process, after a welded joint has been produced, the laser beam is sent and / or deflected into the radiation absorption device, such as an absorption cavity, allowing the beam radiation to be absorbed. the beam continues to deflect during the welding shutdown phase after producing a welded joint and before starting to weld a second welded joint. The process and unit of the invention are particularly suitable for the mass production of parts for the motor vehicle industry, such as bespoke blanks that can be used to manufacture, for example, motor vehicle body components, or for mass production of tubes.
