Description

Welding gas protection drags cover

Technical Field

The utility model relates to the technical field of welding gas protection, in particular to a welding gas protection drag cover.

Background

Because titanium and titanium alloys have a strong affinity for gases such as oxygen, nitrogen, hydrogen, etc. in the air, good protective measures must be taken in the weld zone to ensure that the weld puddle and the front and back sides of the heat affected zone at temperatures exceeding 350 ℃ are isolated from the air. Unprotected titanium absorbs hydrogen at 300 ℃ or above, absorbs oxygen at 600 ℃ or above, absorbs nitrogen at 700 ℃ or above, and causes embrittlement of joints after the gases are absorbed by titanium. Factors such as air suction caused by poor protection, metastable structure caused by rapid cooling of welding lines and heat affected zones, alloy types and the like affect the welding performance of titanium and titanium alloys. Titanium and titanium alloy welding generally use gas protection to drag the cover and protect the weld seam, and current protection drags the cover to constitute by guard shield, intake pipe generally, but it is inseparable with the laminating between the welding work piece, and the protection drags cover and work piece surface to have the clearance for the shielding gas loss is fast, leads to the protection effect not good.

To this end, the present utility model provides a welding gas shielded mop cover.
