Tungsten Electrode TIG Welding Rods
Applications:
Tungsten needle is an elongated structure made of pure tungsten or tungsten alloy of tungsten products obtained. Welding techniques may be used in the electrode material, the instrument can also be used as probes. There are high temperature, electrical conductivity and good.
| Material | tungsten or tungsten alloy |
| Specification | Tungsten needle selection of different sizes, depending on usage. Length of 20mm-150mm diameter 0.5mm-10mm. |
| Applications | Mainly used for engraving metal tungsten needle surface, cutting operation and a single particle in collodion particles. Since these pins are very fragile, so it is often bent or broken. Upon completion of the cutting particles require manual operation. These particles are tungsten needles used not only for cutting, but also for blown crystal and glass blanks. |
Classification:
Tungsten needle can be divided according to the shape of a round rod with a pointed tungsten tungsten needle and needle.
Dimensions:
Tungsten needle selection of different sizes, depending on usage. Length of 20mm-150mm diameter 0.5mm-10mm.
There are two main tungsten needle production process: a metal injection molding process, two drawing molding process.
The basic process is the metal injection molding process, first a uniform solid powder kneaded with an organic binder, after granulation in a plasticized state under heating, using an injection molding machine into the mold cavity solidifying-forming. Then use chemical or thermal decomposition method blanks in the shape of the binder removal, the final densification tungsten needle to get the final product.
