Introduction:

TIG, MIG, ARC, and GAS welding are key techniques used in metal fabrication, each offering unique advantages. TIG (Tungsten Inert Gas) welding provides precision for thin metals, MIG (Metal Inert Gas) welding offers speed for thicker metals, ARC (Shielded Metal Arc) welding is versatile for various applications, and GAS (Oxy-Fuel) welding is effective for cutting and joining metals in different environments. This training program covers these four major welding techniques. Through it, participants will gain in-depth knowledge of the principles, applications, safety protocols, and quality control for each welding method, enabling them to master advanced skills for various industrial applications.
