There are two main shapes of tungsten needles, one is a round rod-shaped tungsten needle, and the other is a pointed tungsten needle.
The round rod-shaped tungsten needle has a relatively slender structure and a metallic surface, and is often used as an electrode for argon arc welding. This tungsten needle generates an arc during welding, and the filler metal is fed in from one side. Under the action of arc heat, the filler metal and the workpiece melt together to form a weld.
Tungsten needles with pointed tips are mainly used for instrument probes, such as digital four-probe testers. This tungsten needle has a sharp tip for precise measurements and testing.
In addition, tungsten needles also have other shapes, such as flat, triangular, etc. These shapes of tungsten needles are mainly designed according to application scenarios and needs.
