Embodiment Construction

[0023] The present invention will be further described below with reference to the drawings and embodiments.

[0024] The main purpose of the concept of the present invention is: during the butt welding operation of vertical plates using a vertical gas-electric automatic welding device (such as a vertical gas-electric welding trolley), the welding wire deposition rate can be increased while the welding heat input to the molten pool can be reduced. Therefore, the welding efficiency and the mechanical properties of the formed weld are greatly improved, and the barrier of the previous gas-electric vertical welding to meet the performance requirements of the weld by improving the performance of the welding material is solved.

[0025] Refer to Figure 1-2 As shown, the present invention provides a double-wire high-efficiency vertical gas-electric water-cooled welding gun. The double-wire high-efficiency vertical gas-electric water-cooled welding gun includes an integrated first welding...

Abstract

The invention relates to a double-wire efficient perpendicular water-cooling electrogas welding gun which is good in radiating effect in a welding process and is high in quality of weld joints. The double-wire efficient perpendicular water-cooling electrogas welding gun comprises a first welding gun and a second welding gun which are integrated, and a cooling circuit is arranged on the double-wire efficient perpendicular water-cooling electrogas welding gun. The double-wire efficient perpendicular water-cooling electrogas welding gun is provided with the cooling circuit, and the cooling circuit, an external water-cooling slider and a water tank can form a welding circulating water cooling system, so that the service life of the double-wire efficient perpendicular water-cooling electrogas welding gun is longer. In addition, owing to the integral structural design, a gun body is thin and is compact in structure, welding efficiency is improved, economical benefit is greatly increased, and mechanical properties of the molded weld joint are high.

Description

Technical field [0001] The invention relates to a welding gun with a double gun structure, in particular to a double-wire high-efficiency vertical gas-electric water-cooled welding gun with easy heat dissipation, high deposition rate and low heat output. Background technique [0002] Nowadays, as vertical gas-electric automatic welding devices are widely used in heavy industry, the application of double-wire welding guns is becoming more and more popular. In the prior art, two welding torches have been fixed and assembled in vertical gas-electric automatic welding devices. The oscillating device adopts split double gun welding. There is no water cooling structure design in this welding gun, and both welding wires in the two welding guns are connected to the positive electrode. [0003] However, the existing double gun structure generally has certain defects. On the one hand, considering its internal considerations, due to long-term high temperature and overheating, and limited by i...
