Argon shield welding device for titanium cup

Abstract

The invention discloses an argon shield welding device for a titanium cup. The argon shield welding device comprises a welding assembly and a rack, and further comprises an argon transmission assemblyand a rotary locating assembly. The rotary locating assembly is arranged on the rack. The welding assembly cooperates with the rotary locating assembly, and the argon transmission assembly is connected with the rotary locating assembly. In the welding process, air is discharged through the argon transmission assembly, the inner side and the outer side of a weld joint of the titanium cup are fullyisolated from air, and the possibility that titanium is prone to being in contact with oxide, hydrogen, nitrogen and the like in the air to generate oxidization or other reactions in the high-temperature molten state is avoided; and the problem that the welding defects of air holes, oxidization and the like are prone to being generated on the surface of the weld joint in the existing process is effectively solved, the quality of a finally-formed product is improved, and titanium plasticity is improved, and the requirement of modern titanium cup production is quite met.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to an argon shielded welding device for a titanium cup. Background technique [0002] Titanium is a transition metal with good corrosion resistance, and its corrosion resistance is far superior to stainless steel in media such as acidic, neutral, alkaline, and high electrolyte solutions. Due to the good corrosion resistance and mechanical properties of titanium materials, it is more and more used in the production and preparation of the cup and pot industry. [0003] However, industrial pure titanium is relatively active in the molten state, and due to the large amount of heat generated during the welding process, in the high-temperature molten state, titanium is easy to contact with oxygen, hydrogen, nitrogen, etc. in the air to cause oxidation or other reactions. Welding defects such as pores and oxidation on the weld surface will cause great harm to product quality, an...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims at the fact that the existing industrial pure titanium is relatively active in the molten state, and because a large amount of heat is generated during the welding process, in the high-temperature molten state, titanium is easy to contact with oxygen, hydrogen, nitrogen, etc. in the air to cause oxidation or other The reaction will not only cause welding defects such as pores and oxidation on the surface of the weld, which will cause great harm to the product quality, but also reduce the plasticity of the oxidized titanium, and the hydrogen in the air will easily make the titanium brittle, thereby further affecting the welding quality. Influence and other defects, a new titanium cup with argon shielded welding device is provided
