What welding techniques are related to inert gas shielding?

The chosen answer focuses on welding techniques that specifically utilize inert gas shielding to protect the weld area from contamination during the welding process. Gas Tungsten Arc Welding (GTAW), Gas Metal Arc Welding (GMAW), and Tungsten Inert Gas (TIG) welding are all methods where inert gases, such as argon or helium, are employed to create a shielding atmosphere around the weld. This prevents oxidation and other forms of contamination, allowing for cleaner welds and better material integrity.

GTAW, also known as TIG welding, is particularly known for its ability to produce high-quality welds on a variety of metals, thanks to the inert gas protection that minimizes atmospheric interference. GMAW is widely used for its speed and efficiency, utilizing a continuously fed electrode wire and also leveraging inert gas shielding to enhance the quality of the weld pool.

While other techniques like Shielded Metal Arc Welding (SMAW) and Resistance Spot Welding (RSW) do not rely on inert gas for shielding their welds, the methods mentioned in the correct answer specifically highlight the relationship with inert gas shielding, making it the appropriate choice for this question.
