Embodiment Construction

[0012] The technical solutions of the present invention will be further described below in conjunction with specific embodiments.

[0013] as attached figure 1 As shown, a titanium tube welding gas shield for fixing a welding torch is composed of an arc-shaped shell 1, a gas introduction pipe 2, a welding operation hole 4, a welding torch fixing device 3, an internal air screen layer 5 and a side groove 6, wherein The gas inlet pipe, welding operation hole and welding torch fixing device are fixed on the upper surface of the arc-shaped shell. The arc-shaped shell and the internal air screen layer are connected into one body by welding, and the two sides of the arc-shaped shell are provided with side grooves. When welding, the device covers the part to be welded, and the welding torch is bound to the welding torch fixing device with a metal hoop, and then the inert gas is introduced into the protective cover through the gas inlet tube, and the argon flow is evenly distributed b...

Abstract

The invention discloses a titanium tube welding gas protection cover of a fixed welding gun. The titanium tube welding gas protection cover comprises an arc-shaped aluminum housing, an argon lead-in tube, an internal gas sifter, a welding gun fixing device and a side surface rubber groove. During the welding process, the protection cover covers a part needed to be welded, and the welding gun is bound to the welding gun fixing device by using a ferrule, then gas is led into the protection cover through the argon lead-in tube, and then argon flow is uniformly distributed to the surface of a welding part through the gas sifter, and finally the side surface rubber groove is filled with rubber so as to enhance argon shield. As the welding gun is fixed to the gas protection cover through the ferrule, a welder fills a welding wire into a welding operation hole by one hand and rotates the gas protection cover by another hand so as to finish the welding operation. The titanium tube welding gas protection cover of the fixed welding gun is simple in structure and convenient to operate, and has a remarkable gas protection effect.

Description

technical field [0001] The invention belongs to the field of welding technology, and more specifically relates to a protective device for performing gas protection on titanium tubes during manual tungsten argon arc welding of titanium tubes. Background technique [0002] Titanium and titanium alloys have good corrosion resistance, high specific strength, good heat resistance and processability, so they are widely used in various fields such as aviation, aerospace, chemical industry and metallurgy. Welding is an indispensable process in the production process of titanium alloy pipe products. In the process of welding titanium and titanium alloys, titanium will absorb hydrogen, oxygen and nitrogen in the atmosphere, which seriously affects the welding quality. Therefore, when manual TIG welding is used to weld titanium alloy pipes, a gas shield must be used to fully protect the welding area with argon gas. Traditional gas shielding devices require two welders to operate, one...
