Durable welds without compromise TIG welding

TIG (Tungsten Inert Gas) welding is one of the most popular and advanced welding techniques used in industry. This method uses a tungsten electrode, which is a non-fusible material, and protective gases such as argon or a mixture of helium and argon are used to protect the weld. It is worth familiarising yourself with this technique because of its versatility, allowing you to weld a variety of materials, including aluminium and stainless steel. This article will provide a detailed explanation of the method, as well as helping to understand the key aspects of the process and the advantages that contribute to its popularity in the industry.

TIG welding is a versatile technique that can be used to weld many different materials. The most commonly welded materials are aluminium, stainless steel, black steel and various aluminium alloys. Each of these materials requires the right choice of welding parameters to produce strong and durable welds.

Depending on the material and type of welding, two types of TIG welding can be used: TIG AC and TIG DC. TIG AC (alternating current) welding is mainly used when welding aluminium, as the alternating current allows oxides to melt more easily on the aluminium surface. DC (direct current) TIG welding is more versatile and can be used to weld a variety of materials, including stainless steel and black steel.

TIG welding can be performed manually by a qualified welder or by robots. Manual welding provides greater control over the process and is ideal for welding complex shapes. Robotic welding, on the other hand, is faster and more efficient for repetitive tasks, but requires proper robot configuration and programming.

Some problems may occur during TIG welding, such as weld pool, cracks, excessive spatter or a non-uniform weld. To avoid these problems, the welder must adjust the welding parameters accordingly, keep the material clean, and use appropriate welding techniques such as current pulsing or orbital motion.
