TIG Welding

Eigen Steel also offers TIG welding services:

Tungsten Inert Gas (TIG) welding, also known as Gas Tungsten Arc Welding (GTAW), is a welding process that uses a non-consumable tungsten electrode to produce the weld. It is a versatile and high-quality welding method that is commonly used for welding thin sections of stainless steel, aluminium, and other non-ferrous metals.

Here's an introduction to TIG welding:

Basic Process

Equipment:

  • TIG welding machine: Provides the necessary power for welding.
  • Tungsten electrode: Non-consumable electrode that produces the arc.
  • Inert gas (usually argon or helium): Shields the weld area from atmospheric contaminants.

Setup:

  • The workpiece and the tungsten electrode are connected to the welding machine.
  • A foot pedal or hand control is often used to regulate the heat input during welding.

Arc Formation:

  • The tungsten electrode is brought close to the workpiece without making contact.
  • The inert gas is used to create a protective atmosphere, preventing oxidation of the molten metal.

Welding Process:

  • The welder guides the electrode along the joint, melting the base metal.
  • Filler metal can be added manually to create a stronger joint (if needed).

Advantages:

  • Produces high-quality, precise welds.
  • Suitable for thin materials and intricate welds.
  • Provides excellent control over the heat input.

Applications:

  • Commonly used for welding stainless steel, aluminium, and other non-ferrous metals.
  • Aerospace, automotive, and precision fabrication industries often employ TIG welding.

Key Features:

  • Non-consumable Electrode:
  • Unlike other welding processes, the tungsten electrode does not melt during welding.

Inert Gas Shielding:

  • The inert gas protects the weld area, preventing oxidation and contamination.

Controlled Heat Input:

  • Welders can precisely control the heat, reducing the risk of distortion or burn-through, especially on thin materials.

Clean Welds:

  • TIG welding produces clean, high-quality welds with minimal spatter.

Versatility:

  • Suitable for various materials and thicknesses, making it a versatile welding process.

TIG welding is favoured in applications where precision and quality are critical. It is widely used in industries where the appearance and integrity of the weld are paramount.

Crafting the future of steel with precision and care.
