Abstract

The invention discloses a double-wire electrogas welding machine. The double-wire electrogas welding machine comprises two welding power supplies, two wire feeders, a double-wire water-cooled welding gun, a welding tractor, a water cooling system, a carbon dioxide supply system and a welding operation box which is electrically connected with the other components. One welding power supply is connected with one wire feeder. The wire feeders, the water cooling system and the carbon dioxide supply system are connected with the double-wire water-cooled welding gun. The double-wire water-cooled welding gun is arranged on the welding tractor. By the adoption of two welding systems composed of the two welding power supplies and by the adoption of the double wire feeders, the double-wire electrogas welding machine is especially suitable for welding thick steel plates and can achieve thermal input needed for weld joint fusion when the thick plates are welded. In addition, the filling quantity of welding wires for vertical welding of the thick plates is much larger than that of welding wires for vertical welding of thin plates, a single wire feeder cannot meet the requirement for welding wire filling, but the filling speed and total quantity of welding wires can be increased manyfold by the adoption of double wire feeding, and thus welding efficiency can be increased manyfold.

Description

technical field [0001] The application belongs to the field of welding technology, and in particular relates to a twin-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, although 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. One step, pre-welding preparation: add a variety of iron alloy elements to the tube coating formula to obtain powder; mix the powder ev...
