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 ...
