Robotic welding torch used in the motorcar industry

摘要

The robotic welding torch incorporates a single or double cooling water circuit, a sleeve nut for securing the hose assembly, and a plug-and-screw gas nozzle with expansion slits. The torch is characterised by the following features: a) an inner tube (1) is arranged centrally over the burner tube (9) and the cover tube (7); b) the burner tube is hermetically joined to the cover tube; c) the inner tube (1) is made of a non-ferromagnetic stiff material; d) an outer tube (2) is arranged centrally over the burner tube as far as the seating (8) for the gas nozzle; e) the outer tube also is made of a non-ferromagnetic stiff material.
