Problems solved by technology

For more than half a century thereafter, there has been no substantial change in the form of this arc welding torch. The prominent problems in its production and use are: (1) the arc of the welding torch is in a free burning state, and the energy density is difficult to achieve. Further improvement makes it difficult to improve welding production efficiency; (2) The current that can be carried is small, and the engineering applicability to medium-thick workpieces above 4 mm becomes poor

Abstract

The invention provides a high-energy arc torch. The high-energy arc torch comprises a main connecting body, a ball valve, a tungsten electrode, a spraying nozzle and a power source connecting end. The main connecting body is a metal conductor and comprises a water inlet pipe, a water outlet pipe, a protective gas inlet pipe, a water inlet connector, a water outlet connector and a gas inlet connector. The ball valve is connected with the main connecting body, the tungsten electrode is connected with the ball valve, the spraying nozzle is connected with the main connecting body, the spraying nozzle is wrapped outside the tungsten electrode, and the power source connecting end is connected with the main connecting body. The high-energy arc torch has the advantages of directly cooling the tungsten electrode, being high in energy density and high in bearing current.

Description

technical field [0001] The invention provides an arc welding torch, in particular to a high-energy arc welding torch capable of directly cooling a tungsten electrode, with high energy density and large carrying current. Background technique [0002] In the 1940s, the United States invented the tungsten electrode inert gas shielded arc welding torch and its technology, which showed excellent effects on the quality of metal material welding. For more than half a century thereafter, there has been no substantial change in the form of this arc welding torch. The prominent problems in its production and use are: (1) the arc of the welding torch is in a free burning state, and the energy density is difficult to achieve. Further improvement causes welding production efficiency to be difficult to improve; (2) the current that can be carried is small, and the engineering applicability to medium-thick size workpieces above 4 mm becomes poor. Contents of the invention [0003] In or...
