This automatic welding equipment is used to weld titanium and titanium alloy sponge material blocks into electrodes. Sponge titanium is pressed into small blocks weighing 200-300kg using a hydraulic press. Subsequently, it must be welded into electrodes weighing 3000-15000kg before smelting. Electrode welding is an essential process step in sponge titanium smelting.
Vacuum plasma automatic welding equipment plays an essential role in the titanium industry’s smelting process. Fully automatic vacuum plasma welding equipment is easy to operate and features a one-touch start function that automatically completes the welding process.

Vacuum creep leveling furnace is used to correct the shape of titanium thin and thick plates and eliminate the hardness. In aviation and aerospace , titanium plates must meet the flatness requirements and completely eliminate the internal hardness of the material.
No other method for leveling or eliminating stiffness in titanium plates can guarantee complete elimination of stiffness. Therefore, only the vacuum creep process can achieve these goals. my country’s aerospace and aviation industries are currently developing, and so are titanium plate leveling equipment for aerospace applications. Dingsheng Company is currently the leading manufacturer of titanium plate leveling equipment in the domestic market.
