TIG Welding

TIG(Tungsten Inert Gas) welding, also called GTAW, is an arc welding process that uses a nonconsumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by a shielding gas (usually an inert gas such as argon), and a filler metal is normally used. A constant-current welding power supply produces energy which is conducted across the arc through a column of highly ionized gas and metal vapors known as a plasma.

TIG Welding Benefits:

  • Superior quality welds
  • Welds can be made with or without filler metal
  • Precise control of welding variables (heat)
  • Free of spatter
  • Low distortion

Resistance Welding

Resistance Welding includes Resistance Spot Welding (RSW), Resistance Seam Welding (RSEW), and Projection Welding (PW). Resistance welding uses the application of electric current and mechanical pressure to create a weld between two pieces of metal. Weld electrodes conduct the electric current to the two pieces of metal as they are forged together。《、平》

  • High speed welding
  • Easily automated
  • Suitable for high rate production
  • Economical
