Tungsten electrode argon arc welding transparent welding gun nozzle used for special angle

Abstract

A transparent torch nozzle for the tungsten-argon arc welding in order to weld by a special angle is made of the refractory transparent Al2O3 (or MgO) ceramic. It can improve the weld qualility when the dead angle is welded.

Description

Technical field: [0001] The invention relates to the improvement of the nozzle of the TIG tungsten argon arc welding torch, in particular to a transparent TIG tungsten argon arc welding torch nozzle which is made of a high-temperature-resistant transparent ceramic material and is used at a special angle. Background technique: [0002] In the welding process, TIG tungsten argon arc welding is favored for its stable arc, good visibility of molten pool, easy control, beautiful appearance and high-quality welds, and is widely used in precision welding and non-ferrous metals of welding. The nozzles of traditional TIG tungsten argon arc welding torches (including air-cooled and water-cooled) are made of ordinary ceramic materials, and the arc and molten pool can only be observed from limited angles and directions during the welding process; In the welding environment, due to the constraints of the controller and other factors, it is easy to have dead angles (the welding is blocke...
