TIG welding

TIG (Tungsten Inert Gas) welding is a welding method used to create high-quality welds on a variety of materials. The technology is known for its precision and purity, making it ideal for applications that require close control of welding parameters.

Silent welding

Technology and process

Welding torch:

A handheld torch is used to create an electric arc between a non-melting tungsten electrode and the workpiece. The tungsten electrode does not melt during the welding process, which distinguishes TIG welding from other methods such as MIG welding.

Inert gas:

An inert gas, usually argon or helium, flows through the torch to protect the weld area from contamination by the oxygen and nitrogen of the air. This prevents oxidation and other chemical reactions that can affect weld quality.

Filling material:

If necessary, a separate welding rod can be used as filler material. The filler material is manually fed into the melt bath to create a strong joint.

Power source:

A current source (DC or AC) is used to maintain the electric arc. The choice between direct current (DC) and alternating current (AC) depends on the material being welded. For example, AC is commonly used for aluminum welding.

Advantages of TIG welding

Precision:

TIG welding enables very fine control over welding parameters such as amperage and heat intensity, resulting in high-quality welds.

Purity:

The inert gas atmosphere used in TIG welding prevents contamination and oxidation, resulting in clean and strong welds.

Flexibility:

Can be used on a wide range of materials including steel, stainless steel, aluminium, titanium and magnesium.

Aesthetics:

Produces welds with excellent visual quality, which is important for applications where the appearance of the weld is critical, such as in art and decorative metalwork.

Control:

Enables welding in all positions (horizontal, vertical, overhead).

Areas of use

Aviation industry:

Used to weld parts that require high precision and structural integrity.

Automotive industry:

Welding of high-quality and aesthetic parts, including exhaust systems and engine blocks.

The food industry:

Welding of stainless steel equipment that must be free from contamination.

Medical equipment:

Welding of surgical instruments and medical equipment that require high sterility and precision.

Arts and Crafts:

Creation of decorative and artistic metalwork.

Important factors to consider

Experience:

TIG welding requires a high degree of skill and experience. The operator must have good hand-eye coordination and a deep understanding of the material's properties.

Equipment:

High-quality equipment is necessary to achieve optimal results. This includes a reliable power source, suitable electrodes and high quality inert gas.

Environment:

The welding area must be clean and free of drafts that could affect the gas flow and weld quality.
