Pure tungsten electrodes, as one of the earliest electrodes used in argon arc welding, have consistently played a significant role in the welding industry. This type of electrode, characterized by its high melting point, high density, corrosion resistance, and excellent electrical and thermal conductivity, has become an indispensable key material under specific welding conditions.

Tungsten disulfide nanosheet (WS₂ nanosheet) is a typical transition metal tungsten compound. There are many different preparation methods, each of which has its own unique principles, operation procedures, advantages and disadvantages.

The types of tungsten electrodes are mainly classified according to the different rare earth oxides or alloy elements doped in them. Here are the common types of tungsten electrodes and their characteristics:

Tungsten disulfide nanosheet (WS₂ nanosheet) is a typical two-dimensional nanomaterial with a large specific surface area, a low friction coefficient, good electrochemical performance, and optical properties. It has great potential in the fields of nanoelectronics, optoelectronic devices, flexible electronics, lubricating materials, and chemical catalysis. So, what are the factors that affect tungsten disulfide nanosheet performance?
