Titanium is a metal material commonly used in the processing of precision automotive stamping parts. Titanium alloy is an alloy material composed of titanium as the basic element and mixed with other metal elements. It has the advantages of low density, high strength, good corrosion resistance, high heat resistance, easy welding and good process performance. It can be processed into various titanium alloy products, which are widely used in the following industries.

In the application of aviation and shipbuilding industry, the specific strength of titanium alloy is higher than that of other light metals, steel and nickel alloys, and this advantage can be maintained to about 500C. Therefore, some titanium alloys are suitable for stamping into gas turbine parts. About 80% of the titanium output is used in aviation and aerospace industry. In the structural materials of aircraft body, titanium alloy is mainly used to manufacture fuselage, wing, skin and load-bearing components, accounting for a high proportion.

A large number of cold stamping processes are used in the production of automotive stamping parts, which is suitable for the needs of mass production of A106B seamless pipes with multiple varieties in the automotive stamping industry. In medium and heavy-duty vehicles, most of the covering parts such as body outer plate, and some load-bearing and supporting parts such as frame, carriage and other auto parts are auto stamping parts.

The steel used for cold stamping is mainly steel plate and steel strip, accounting for 72.6% of the steel consumption of the whole vehicle. Cold stamping materials are closely related to the production of automobile stamping parts. The quality of materials not only determines the performance of products, but also directly affects the process design of automobile stamping parts, and affects the quality, cost, service life and production organization of products. Therefore, the rational selection of materials is an important and complex work.

After all grinding construction is completed, the repaired surface and its surroundings shall be cleaned again, and the adjacent parts shall be pasted with self-adhesive tape for protection as required; If necessary, brush the bare metal surface with two-component metal surface conditioner. Then spray primer, putty and intermediate coating, and polish appropriately if necessary; Spray sealing primer; Apply a suitable finish.
