Single wire electrogas welding machine

Abstract

The invention discloses a single wire electrogas welding machine. The single wire electrogas welding machine comprises a welding power supply, a wire feeding machine, a single wire water cooling welding gun, a welding tractor, a set of water cooling system, a set of carbon dioxide gas supply system, and a welding operation box electrically connected with the parts, wherein the welding power supply is connected with the wire feeding machine; the water cooling system and the carbon dioxide gas supply system are connected to the single wire water cooling welding gun; and the single wire water cooling welding gun is arranged on the welding tractor. The single wire electrogas welding machine is suitable for welding a thick steel plate, in particular a thick steel plate with a thickness within 60 mm, and is stable in process, convenient for operation and excellent in welding line quality; and the production efficiency of the single wire electrogas welding machine is higher than that of manual arc welding by more than 10 times.

Description

technical field [0001] The application belongs to the field of welding technology, in particular to a single-wire gas-electric vertical welding machine. Background technique [0002] With the rapid development of my country's economic construction, thick steel plate steel structure welding has appeared in large numbers in metallurgy, shipbuilding, petrochemical, water conservancy and other industries. For the vertical seam welding of steel plates with a thickness of 60-100 mm (or even thicker), there is no high-quality and efficient welding method and related equipment. It is difficult to solve this problem with electrode arc welding, but electroslag welding can solve this problem. For example, the application number is 201010180014.8, and the invention name is the patent of the welding method of the thick plate butt joint. The first step, preparation before welding: add various ferroalloy elements to the tube coating formula to obtain powder; add adhesive to the powder aft...
