An Overview of TIG Welder

TIG welder, also known as Gas Tungsten Arc Welding (GTAW), is a highly precise and versatile welding process that is widely used in various industries for its ability to produce high-quality, clean, and aesthetically pleasing welds. This method is particularly effective for delicate seams, thin materials, and a range of metals including non-ferrous ones like copper, aluminium, and brass.

How TIG Welder Works

TIG welding utilizes a non-consumable tungsten electrode to produce an arc that generates heat for welding. The process involves holding the TIG torch in one hand while feeding a filler material with the other. A foot pedal or hand control is used to regulate the welding current. The tungsten electrode is shielded by an inert gas (usually argon), which protects the weld area from atmospheric contamination. This results in a clean weld with minimal spatter.

Components of a TIG Welding System

  • Power Source: Supplies electrical energy for the welding process.
  • TIG Torch: Holds the tungsten electrode and controls the shielding gas flow.
  • Tungsten Electrode: Creates the welding arc and withstands high temperatures.
  • Shielding Gas: Typically argon, it protects the weld from contamination.
  • Filler Metal: Optional material added to reinforce the weld.
  • Gas Cylinder: Stores the shielding gas.
  • Foot Pedal/Hand Control: Adjusts the welding current.

Materials Suitable for TIG Welding

TIG welding is compatible with a variety of materials, including:

  • Aluminum: Optimal choice for precision applications.
  • Stainless Steel: Employ a DC machine with negative electrode polarity.
  • Steel: Suitable for various steel types, including carbon and low-alloy steel.
  • Chromoly: Ideal for motorsports and bicycle manufacturing.
  • Nickel Alloys: Common in power generation, chemical processing, and aerospace.

Advantages and Disadvantages


  • Produces precise, clean, and attractive welds.
  • Versatile for a wide range of metals and thin materials.
  • Strong and reliable welds with minimal spatter and post-weld cleanup.
