TIG Welding

While it may be the most difficult welding discipline to master, TIG Welding is a highly precise, efficient process which produces excellent results.

TIG Welding is commonly used for architectural & automotive work and is an ideal process for thin materials and jobs which require a high degree of cleanliness.

Importantly, there are two modes of TIG Welding processes – DC and AC – and these determine which types of materials are able to be welded.

Direct Current (DC) Welding is used for all metals except aluminium and magnesium alloys while Alternating Current (AC) Welding can only be used on aluminium and magnesium alloys.

Should you need a machine capable of welding Aluminum then you will require a TIG Welder which has AC/DC capability.

Most modern AC Welding Machines are inverter types which also have DC Capacity.

TIG Welding Summary

  • Produces precise, high-quality welds
  • Best method for use on thin materials
  • Most difficult welding process to master
  • Commonly used on architectural and automotive work
  • Produces no slag so is the preferred process for jobs which require high levels of cleanliness
  • High-end TIG machines with pulse capability allows for fine welds with low heat effected zones.
  • Can be used on all metals. However, AC Output is required for use on aluminium and magnesium alloys.
  • Aesthetic-driven weld beads achieves seamless look
  • Allows heat input adjustment with a foot control
