What Are the Uses of Thoriated Tungsten Needles?

Thoriated tungsten needles have a wide range of applications due to their special physical properties. The following are the main uses of thoriated tungsten needles:

  1. Welding field: Thoriated tungsten tungsten needles have important applications in the welding field, especially for the welding of carbon steel, stainless steel, silicon steel, copper, bronze, titanium and other materials. It is the main electrode material for non-melting argon arc welding, such as manual argon arc welding machine, automatic argon arc welding machine, automatic pipe welding machine, automatic tube sheet welding machine, hot wire TIG welding machine, etc. It will be used. This is because thoriated tungsten needles are easier to arc, the arc is more stable, have a higher current carrying capacity, and have a long service life.
  2. Electronic testing field: Thorium tungsten tungsten needles are also used in electronic probe components, such as digital four-probe testers, four-probe resistivity square resistance probes, silicon material composite testers, semiconductor conductive model identifiers, etc.
  3. Other fields: In addition to the above two fields, thoriated tungsten tungsten needles are also used in the manufacture of cathode discharge needles, such as ion blowers, ion blowers, ion blowers, ion blowers, electrostatic rods and other equipment.

Please note that although thoriated tungsten needles have the above wide range of applications, because they contain radioactive elements, special attention must be paid to safety issues when using them. When using them, please consult the professional technicians of CTIA GROUP LTD.
