A significant feature of titanium plate is its strong corrosion resistance, which is due to its strong affinity for oxygen and the ability to form a dense oxide film on its surface, which can protect titanium from medium corrosion. It has good stability in acidic, alkaline, neutral saline solutions and oxidizing media, and has better corrosion resistance than existing stainless steel and other commonly used non-ferrous metals.

The quality of titanium plates largely depends on the smelting process of the titanium plate manufacturer, including the chemical composition of titanium, the cleanliness of titanium water (gases, harmful elements, inclusions), and the quality of the casting billet (component segregation, decarburization, and surface condition). These are the key control points of the smelting operation.

In addition, industrial titanium plates also require sufficient hardenability to ensure uniform microstructure and mechanical properties of the entire spring cross-section. The main cause of fatigue cracks is oxide inclusions in titanium, and the harm of D-type inclusions to fatigue life is greater than that of B-type inclusions. Therefore, foreign titanium and automobile factories have put forward higher requirements for oxide inclusions in industrial titanium plates, such as the Swedish SKF standard requiring oxygen content in titanium to be less than 15 × 10-6, D type inclusions are lower than B type inclusions. Especially Al2O3 and TiN inclusions pose a great threat to the fatigue life of titanium springs. In order to produce high-quality industrial titanium plates, special smelting methods such as electric furnace Electro-slag remelting or vacuum arc remelting were usually used in the past.

Due to the unique physical and chemical properties of titanium plates, their welding process differs greatly from other metals. Titanium welding is a TiG welding process that effectively protects the welding area using inert argon gas. Before using argon gas, the factory certificate on the bottle body is checked to verify the purity index of the argon gas, and then the bottle valve is checked for any leakage or malfunction.

When welding titanium plates, it is necessary to ensure that:

The metal in the welding zone is not polluted by the active gas N0H and harmful impurity element CFeMn when the temperature is above 250 ℃. The purity shall not be less than 99.98%, and the water content shall be less than 50Mg/m32. Argon: industrial grade pure argon.

Unable to form coarse grain structure. The welding process must follow the predetermined construction sequence and cannot generate significant welding residual stress and deformation. Therefore, strictly following the quality management standards of the process, implementing quality control throughout the entire process, ensuring that all factors such as personnel, machinery, materials, and methods are in a good controlled state, thereby ensuring their quality within a reasonable construction period.
