FAQ

A MIG welding machine, also known as a gas metal arc welding (GMAW) machine, is a type of welding equipment used to join metal parts together using an electric arc and a wire electrode. The machine works by feeding a spool of welding wire through a gun connected to the machine. The welding wire is made of a metal core surrounded by a shielding gas that protects the weld from atmospheric contaminants. As the operator pulls the trigger on the gun, the welding wire is fed through the gun and simultaneously energized by the welding machine, creating an electric arc between the wire and the metal being welded. The heat generated by the arc melts the wire and the metal being welded, fusing them together. The operator controls the welding process by adjusting the wire feed speed and voltage settings on the welding machine. The machine also regulates the flow of the shielding gas to protect the weld from contamination. MIG welding machines are widely used in various industries, including automotive manufacturing, metal fabrication, and repair work. They are known for their versatility, ease of use, and ability to produce high-quality welds quickly and efficiently.

A TIG welding machine, also known as a gas tungsten arc welding (GTAW) machine, is a type of welding equipment used to join metal parts together using an electric arc and a tungsten electrode. The machine works by creating an electric arc between the tungsten electrode and the metal being welded. The operator uses a foot pedal or hand controller to control the welding process and manually feed a filler rod into the weld pool as needed. The tungsten electrode does not melt during the welding process, but instead creates a stable arc that generates intense heat, melting the metal being welded. The operator uses a shielding gas, typically argon, to protect the weld from atmospheric contamination. TIG welding machines are known for their precision and ability to produce high-quality welds on a variety of metals, including aluminum, stainless steel, and copper alloys. They are commonly used in industries such as aerospace, automotive manufacturing, and precision metal fabrication. TIG welding requires more skill and experience than other welding processes, but it is valued for its ability to produce clean, precise welds with minimal distortion and high aesthetic appeal.

The broad purpose of the occupation is to manually weld tubes and pipes to high standards of quality and integrity using a minimum of two manual arc welding processes from Tungsten Inert Gas (TIG), Plasma Arc Welding (PAW), Manual Metal Arc (MMA), Metal Inert Gas (MIG)/Metal Active Gas (MAG) and Flux Cored Arc Welding.

The three most common welding types are – Arc, MIG and TIG welding.
