What is TIG Welding?

TIG welding stands for Tungsten Inert Gas Welding. It is an arc welding process that uses a non-consumable tungsten electrode to create a weld. As the name implies, this method uses inert gas, typically argon or helium. You may wonder about the necessity of inert gases in the welding method. It technically shields the weld area from atmospheric contamination. TIG welding is mainly famous for its ability to produce high-quality welds.

The working principle of TIG welding is simple. The process establishes a stable arc between the tungsten electrode and the workpiece. The intense heat generated melts the base metal to reinforce the weld joint. At this stage, the tungsten remains intact, and the inert gas shield ensures a clean and controlled environment for welding.

The application of TIG welding can be observed in many industry fields. The method’s versatility makes it well-suited for various applications across these fields. We can find the most common applications in the aerospace, automotive, and electronics industries. Compared to laser welding, TIG welding offers the most cost-effective solution. They are also flexible and efficient for many applications.

One of the significant advantages of using this method is their ability to work with thicker materials.

TIG vs Laser Welding: Precision & Accuracy

Both Laser welding and TIG welding offer greater precision & accuracy. Laser welding is more precise than other methods because of the focused laser beam. The concentrated laser with minimal heat-affected zone ensures minimal distortion. This level of accuracy made laser welding ideal in electronics and medical device fabrication.

On the other hand, TIG welding offers less precision than laser welding. You know this method involves manual manipulation and filler rod usage. As a result, skilled welders can only achieve a certain level of precision. Therefore, for TIG welding, skill mastery is essential for quality welds.

Laser Weld vs TIG: Head-affected Zone

The heat-affected zone (HAZ) is the region surrounding the welding during welding. This zone is where the primary material undergoes heat changes without completely melting. HAZ is a critical aspect of welding. You know it influences the material’s properties.

Laser welding typically minimizes this heat-affected zone by concentrating laser beam energy precisely. As a result, it also reduces thermal diffusion. Consequently, you can get less material distortion and preserve the base material’s properties. On the other hand, TIG welding generates a larger heat-affected zone compared to laser welding. It happens due to the broader heat dispersion associated with the welding arc. Consequently, this increased heat exposure may lead to significant changes in material properties.

Laser Welding vs TIG Welding: Versatility

Both laser welding and TIG welding are versatile on various types of metals. But when we talk about the suitability, we can find the differences. Laser welding is popular for welding stainless steel, aluminum, titanium, copper, and brass. On the other hand, TIG welding prefers carbon steel, stainless steel, aluminum and its alloys, copper & brass, and nickel alloys.

Technically, TIG welding is more suitable for reflective surfaces. Some laser welders from Hanten CNC are ideal for welding these metals. Therefore, while choosing a laser welding machine, you must consider some technical terms.
