TIG Welding

The Tungsten Inert Gas (TIG) process, uses the heat generated by an electric arc struck between a non-consumable tungsten electrode and the workpiece to fuse metal in the joint area and produce a molten weld pool. The arc area is shrouded in an inert or reducing gas shield to protect the weld pool and the non-consumable electrode. The process may be operated autogenously (without filler), or filler may be added by feeding a consumable wire or rod into the established weld pool.

  • The addition of filler is optional
  • Only inert or reducing gases can be used as the shielding gas
  • TIG welding is a high-quality, versatile and commonly-used process
  • TIG is suitable for welding ferrous and non-ferrous materials
  • The TIG process can be run on DC-, DC+, or AC

The TIG process is capable of producing very high-quality welds in a wide range of materials and in thicknesses up to about 8 or 10mm. It is particularly suited to welding of sheet material and for putting in the root run of pipe butt welds.

The process tends to be very clean, producing little particulate fume, although it is capable of generating ozone in appreciable amounts and is not regarded as a high-productivity process.
