The invention discloses a welding wire feeding gun for argon arc welding TIG welding. The welding wire feeding gun includes a gun-shaped body, a porcelain nozzle, a first wire feeding guide pipe, a wire feeding mechanism, a damping check device and a second wire feeding guide pipe; the gun-shaped body includes a shell, a rotating shaft and a trigger; the porcelain nozzle is arranged at the muzzleend of the front end of the shell; the first wire feeding guide pipe is arranged in the rear end of the shell; the wire feeding mechanism is arranged at the position, at the tail end of the first wirefeeding guide pipe, of the inner part of the shell; and the second wire feeding guide pipe is arranged at the position, between the trigger and the damping check device, of the inner part of the shell. The welding wire feeding gun for argon arc welding TIG welding is simple in structure, simple to operate and convenient to carry; the wire feeding length can be effectively controlled, and the wirefeeding angle is controlled conveniently, and the wire feeding can be realized by pulling the trigger, and the operation difficulty of operators is reduced; and the adjustable setting of the dampingcheck device can meet the wire feeding of welding wires of various specifications, the scope of application is increased, and the utilization rate is high.
Description
technical field [0001] The invention belongs to the technical field of welding tools, in particular to a welding wire feeding gun for argon arc welding and TIG welding. Background technique [0002] TIG welding, argon arc welding, non-melting electrode argon arc welding manual welding. It can weld stainless steel, high temperature alloy, titanium alloy, aluminum alloy and other materials, and is widely used in the welding of pressure vessels and pipelines. It has flexible operation and high weld seam quality, and can obtain high-quality welding quality and appearance. Argon arc welding priming process, after non-destructive testing, radiographic flaw detection, the weld grade is above grade II. During manual TIG welding, it is necessary to continuously fill the welding arc molten pool with welding wire, the length of the welding wire is about 1000mm, and the diameter is Φ1 mm to Φ4mm. Due to the limitations of various working conditions, during welding, the welder uses hi...
