Introduction to CO2 Welding
CO2 welding, also known as Gas Metal Arc Welding (GMAW), is a welding process that utilizes a continuous solid wire electrode and a shielding gas. It is widely known for its versatility and ability to weld various types of metals, making it a preferred choice for both small-scale workshops and large manufacturing units.
How CO2 Welding Machines Work
CO2 welding machines work by creating an electrical circuit between the welding gun and the workpiece. An arc is generated, and as the wire electrode is continuously fed, it melts and fuses with the base metal. The shielding gas, typically carbon dioxide, protects the weld pool from atmospheric contamination, ensuring a clean and strong weld.
