Description

Technical Field

[0001] The utility model relates to the technical field of titanium tube welding, and more specifically to a titanium tube welding auxiliary device. Background Art

[0002] Titanium tubes require special protection during welding due to their material properties. Under high temperatures during welding, the weld seam, when exposed to air, will oxidize, affecting weld quality and failing to meet quality requirements. Therefore, the completed weld seam must be immediately protected during welding to prevent oxidation. This is why titanium tube welding shields are developed. By injecting inert gas into the shield, the high-temperature weld seam can be protected during welding.

[0003] However, the protective cover used for titanium tube welding protection in the existing technology is mostly separated from the welding gun. In the process of moving the welding gun, the protective cover needs to be continuously moved to cover the weld part that has just been welded. There are many inconveniences in actual operation, which is not conducive to efficient welding. The problem of reduced inert gas protection effect often occurs due to untimely or inadequate movement of the protective cover, which affects the quality of titanium tube welding. In view of this, we propose a titanium tube welding auxiliary device. Utility Model Content
