Abstract

The invention provides a high-efficiency water-cooled argon arc welding torch, which is composed of a handle, a torch head body, a torch head body sheath, a rear cap, a tungsten pole rod, a tungsten pole clamp, an inner heat insulation sleeve, an outer heat insulation sleeve, an outer connection sleeve, The nozzle connection ring is composed of ceramic nozzles, in which the middle of the handle is provided with an air inlet pipe, an inlet pipe and an outlet pipe, the right end of the handle is connected with the outer casing of the gun head body, and the lower end of the air inlet pipe is connected with the upper end of the gun head body The air intake hole on the side is connected, and the air intake hole is connected with the vertical through hole in the center of the gun head body. A tungsten pole clip is set in the middle of the vertical through hole. The ring groove, the inner circle of the inner heat insulation sleeve is tightly fitted on the outside of the ring groove to seal the ring groove into a water cooling jacket, the water inlet pipe and the water outlet pipe are connected with the water cooling jacket, and an outer insulation Heat sleeve, the outer heat insulation sleeve is connected with the inner circle of the upper end of the ceramic nozzle, the lower end of the gun head body sheath is provided with an outer connecting sleeve, the lower end of the outer connecting sleeve is connected to the nozzle connecting ring, and the connecting ring and the outer circle of the upper end of the ceramic nozzle pass through the thread Screwed together, the rear cap is set on the top 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
