Efficient water-cooling argon arc welding gun

Abstract

The invention provides an efficient water-cooling argon arc welding gun. The efficient water-cooling argon arc welding gun is composed of a handle, a gun head body, a gun head body protecting sleeve, a rear cap, a tungsten electrode rod, a tungsten electrode clamp, an inner heat insulation sleeve, an outer heat insulation sleeve, an outer connection sleeve, a spray nozzle connection ring and a ceramic spray nozzle, wherein the middle of the handle is provided with a gas inlet pipe, a water inlet pipe and a water outlet pipe; the right end of the handle is connected with a machine head body outer sleeve covering the exterior of the gun head body; the lower end of the gas inlet pipe is connected with a gas inlet hole in the side face of the upper end of the gun head body; the gas inlet hole communicates with a vertical through hole in the center of the gun head body; the tungsten electrode clamp is arranged in the middle of the vertical through hole; the tungsten electrode rod penetrates a middle hole of the tungsten electrode clamp; an annular groove is machined in the middle of the outer circle of the gun head body; the exterior of the annular groove is closely sleeved with the inner circle of the inner heat insulation sleeve, and the annular groove is closed into a water-cooling sleeve; the water inlet pipe and the water outlet pipe communicate with the water-cooling sleeve; the outer heat insulation sleeve is arranged outside the inner heat insulation sleeve; the exterior of the outer heat insulation sleeve and the inner circle at the upper end of the ceramic spray nozzle are connected together in a sleeving manner; the outer connection sleeve is arranged at the lower end of the gun head body protecting sleeve; the spray nozzle connection ring is connected to the lower end of the outer connection sleeve and connected with the outer circle at the upper end of the ceramic spray nozzle in a thread screwing manner; and the rear cap is arranged at the top end of the gun head body.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a high-efficiency water-cooled argon arc welding torch. Background technique [0002] Argon tungsten arc welding is a kind of gas shielded welding that uses inert gas as a shield. It is a process of welding by heating the base metal and filler material with the help of the high-temperature heat of the arc generated between the tungsten electrode and the weldment. It is arc welding equipment composed of welding machine, welding torch, control box, water and electricity, ground wire and other ground wire clamps, and tungsten auxiliary device. The traditional way of connecting the positive and negative poles of the power supply of the welding torch and the workpiece depends on the different materials to be welded. Usually, the gas is used as the shielding gas, and the tungsten electrode is used as the non-melting electrode. The base metal is heated and melted to achieve welding. It...

AI Technical Summary

Problems solved by technology

Due to the small working current and low welding temperature of ordinary welding guns, the welding effect is poor. When used in special welding, it will cause welding difficulties and affect welding efficiency. There are problems such as slow speed, non-concentrated temperature, high equipment investment cost, and large consumption of shielding gas. defect

The air flow is difficult to control, the heat dissipation of the welding torch is poor, the tungsten electrode is severely ablated, the arc cannot be accurately controlled, and the operation is also troublesome
