What is the stainless steel mesh frame of chopsticks?

Stainless steel grid for chopsticks is high frequency argon arc welding. Argon arc welding uses inert gas to protect solder joints from oxidation during welding, while high-frequency solid-state welding machine uses high-frequency instantaneous heating characteristics to realize rapid welding of welding body, which can also achieve anti-oxidation effect. The latter is mostly used for deep welding of large parts, but argon arc welding is difficult to do this.

Advantages of high frequency argon arc welding

Argon protection can isolate the adverse effects of oxygen, nitrogen and hydrogen in the air on the arc and molten pool, reduce the burning loss of alloy elements, and obtain dense, splash-free and high-quality welded joints.

The biggest feature is that there is no splash. Argon arc welding has the advantages of stable arc combustion, concentrated heat, high arc column temperature, high welding production efficiency, narrow heat affected zone and small tendency of stress, deformation and crack of welded workpiece. To sum up, the biggest feature is small deformation. Argon arc welding is open arc welding, which is convenient for operation and observation.

The electrode loss is small, the arc length is easy to maintain, there is no flux and coating during welding, and it is easy to realize mechanization and automation. Argon arc welding can weld almost all metals, especially some refractory and oxidizable metals, such as magnesium, titanium, molybdenum, zirconium, aluminum and their alloys.
