The tungsten needle for argon arc welding is a tungsten product with a slender structure and made of pure tungsten or tungsten alloy. It is mainly used as an electrode material in argon arc welding technology. Tungsten needles have the advantages of high temperature resistance and good electrical conductivity. They usually come in two forms: round rod shape and pointed tip. During the argon arc welding process, a tungsten needle acts as an electrode and generates a high-temperature arc to melt the welding metal and form a joint.
