Description

Technical Field

[0001] The utility model relates to the technical field of titanium alloy welding, in particular to a titanium alloy butt welding protection device. Background Art

[0002] Titanium and its alloys have strong gas absorption capacity. Pure titanium starts to absorb hydrogen at about 250°C, oxygen at 400°C, and nitrogen at 600°C. After titanium and its alloys absorb a small amount of these gases, the gas atoms will be dissolved in the lattice in the form of interstitial or substitution, changing the original lattice arrangement of the material and reducing the performance of titanium and its alloys. Therefore, vacuum welding and inert gas welding are usually used when titanium alloys are welded.

[0003] The cost of vacuum welding is too high. Under normal circumstances, factories usually use inert gas welding, so a welding protection device is needed. The sealing performance of the existing welding protection device is difficult to control, which makes it easy for outside air to enter the welding protection device, and it is difficult to dissipate the high temperature generated by welding, which causes the roller mold to be heated and reduce its life. Therefore, we propose a titanium alloy butt welding protection device to solve the above problems. Utility Model Content
