Process of TIG welding with a a robotic TIG welding torch having a nozzle/wire guide assembly

摘要

The assembly has a nozzle (11) for delivering gas and a wire-guide system (13) for guiding a fusible wire. A front end (20) of the system opens inside the nozzle. A peripheral side of the nozzle has a groove (10) crossed by the system. The system is connected to the nozzle and has a part parallel to an axis of the nozzle followed by a curved part. The parallel and curved parts are located outside the nozzle. Independent claims are also included for the following: (a) a tungsten inert gas (TIG) welding torch having a nozzle/wire-guide (b) an automatic welding installation having a TIG welding torch.
