Problems solved by technology

[0004] The purpose of the present invention is to provide a method that can effectively prevent the atmosphere from entering the protected area, and the weld seam is not easy to weld in order to solve the problem that the defects of titanium alloy components can only be welded in the vacuum container and the weld metal is easy to oxidize and nitride during the titanium alloy welding process in the above-mentioned prior art. Oxidation or nitriding, concentrated arc temperature, small heat input, fast speed, small heat-affected area, can eliminate arc drift phenomenon, easy to operate, especially a cold-air argon arc welding torch that can weld titanium alloy components in a natural environment

Embodiment Construction

[0013] Fig. 1 has described the gun body that has nozzle and the handle that connects gun body, tungsten electrode nut and electrode chuck form a best embodiment of cold gas type argon arc welding torch. It consists of handle 1, button 2, sealing gasket 3, electrode nut 4, gun body 5, electrode chuck 6, tungsten electrode 7, nozzle 8 and gas lens 9, as well as control lines, argon arc pipes, cables, etc. composition. The handle 1 that button 2 is housed is electrically connected with the control line in the form of the prior art, and its pipeline is the passage that enters argon. An electrode nut 4 and a nozzle 8 are fixedly connected to the upper and lower ends of the gun body 5 integrally connected by brazing with a copper tube. The electrode nut 4 is sealed and connected to the gun body 5 through the gasket 3 . A tapered reflective wall 12 is formed on the upper end of the nozzle 8 made of ceramics or high-temperature-resistant non-metallic insulating material. In the ca...

Abstract

The invention relates to the argon cold air arc welding machine. It has top and down air chamber through the screen current and connected to the nozzle, and separated by rigid air lens with intersected through holes. The air lens is divided into top and down air chambers, forming effective isolation air multi layer post screening the current. It forms multi layer protective layer current. It has concentrated electric arc temperature, small thermal input, quick speed, and less thermal influence. It solves existing technical issues, avoids the location limitation of vacuum argon filling welding equipment. It realizes welding under natural conditions.

Description

technical field [0001] The invention relates to a DC tungsten which is suitable for carbon steel, alloy steel, stainless steel, refractory metal aluminum and aluminum-magnesium alloy, copper and copper alloy, titanium and titanium alloy, and ultra-thin plates of 0.3 mm, and can be welded in all directions at the same time. TIG gas-cooled torch. A cold gas argon arc welding torch mainly used for welding titanium alloy components. Background technique [0002] Manual argon tungsten arc welding in the known technology is a kind of gas-shielded welding using inert gas as shield, and belongs to non-melting pole. It uses the high-temperature heat of the arc generated between the tungsten electrode and the weldment to heat the base metal and filler material to achieve welding. It consists of welding machine, welding torch, control box, water and electricity, ground wire and other ground wire clamps, and tungsten auxiliary device to form argon arc welding equipment. The positive ...
