This fast welding method is well-suited for both thin and thick materials, making it a popular choice for a wide range of applications.
“MIG welding is a game-changer for industries that require speed and versatility in their welding processes. The combination of efficiency and material compatibility makes it an invaluable tool for modern fabrication.”
What is TIG Welding?
TIG (Tungsten Inert Gas) welding is a precise and versatile welding technique that produces high-quality welds. Unlike other welding methods, TIG welding utilizes a non-consumable tungsten electrode and a separate filler material, allowing for exceptional control and precision during the welding process.
How TIG Welding Works
In TIG welding, an electric arc is struck between the tungsten electrode and the workpiece, creating intense heat. This heat melts the base metal, and the welder manually adds a filler material to the joint, forming a strong, high-quality weld. The process is further enhanced by the use of an inert gas, such as argon or helium, which shields the weld from atmospheric contamination, ensuring optimal weld integrity.
