Background
At present, in the post-treatment construction and installation engineering of spent fuel, a large number of titanium alloy process pipelines need to be welded, the titanium alloy process pipelines have various specifications and sizes, and because titanium is a metal with strong activity, the titanium alloy has great affinity to oxygen, hydrogen, nitrogen and other gases along with the rise of temperature in the pipeline welding process. Titanium begins to absorb hydrogen when heated to more than 300 ℃, and when the temperature is higher than 500 ℃ and 700 ℃, hydrogen and nitrogen in air are easily absorbed during welding, so that the welding quality is seriously influenced. In order to ensure the welding quality, the molten pool and the heat affected zone must be fully protected by gas.
In the prior welding process, the welding of titanium or titanium alloy needs to be carried out by utilizing a vacuum box or a common support cover, the vacuum box usually needs a large space position for welding environment, the actual welding environment on site is narrow, and the welding process is not suitable for the welding operation of the vacuum box. The common support cover has the defects of over-fast flow of the protective gas and uneven flow of the protective gas, so that the welding seam is not formed well, the welding quality is influenced, and partial welding seams need to be repaired, thereby reducing the production efficiency.

Detailed Description
Referring to fig. 1 and 2, the gas protection device for welding the titanium alloy pipeline comprises a gas protection device body 1, a gas pipe connector 2, a fixing buckle 3 and a high-temperature resistant sealing strip 5, wherein the gas protection device body 1 is made of a copper plate and is 1mm thick; the welding process has the advantages of better heat dissipation, better stability and longer service life. The whole gas protection device body 1 is of a circular arc-shaped structure, so that the gas protection device body 1 can be tightly attached to the outer wall of the titanium alloy pipeline and can be suitable for the construction environment with multiple and complicated pipelines.
One end of the air pipe connecting port 2 is welded with the gas protection device body 1.
One end of the fixed buckle 3 is welded with the gas protection device body 1, the fixed buckle is of a semi-closed structure, and the positioning bolt 3-1 is arranged on the fixed buckle and can be used for adjusting the size of the fixed buckle, so that the gas protection device is suitable for welding gun nozzles of different specifications.
