Key Features:

• Different Types of Shielding Gases: Inert (e.g., Argon, Helium): these gases do not react with the weld pool and are suitable in most cases for TIG (GTAW) and MIG (GMAW) processes.
• Improved Properties: Covering the weld from atmospheric gases like oxygen and nitrogen preventing oxidation and outside contamination. Stabilizing, that is, improving arc stability for better controlled and consistent welding.  Improves the weld appearance surface finish by controlling spatter and porosity. 
• Wide Applications: MIG Welding (GMAW): Smooth Strong welds achieved by using pure argon or gas mixture with CO₂. TIG (GTAW): Pure argon or helium gas is preferred in this form of welding for precision welding works on aluminum, stainless steel, and many exotic metals. 

Gas shielding ensures quality assurance, consistency with respect to weld, and defect-free weld condition in all sectors from automotive to aerospace, shipbuilding, and construction. The improvement in new gas shielding techniques and gas mixtures improves weld, weld efficiency, and cost-effectiveness for modern welding applications.
