Four Popular Types of Welding Procedures
The four main types of welding are: Gas Metal Arc Welding (GMAW/MIG), Gas Tungsten Arc Welding (GTAW/TIG), Shielded Metal Arc Welding (SMAW), and Flux Cored Arc Welding (FCAW) Gas Metal Arc Welding (GMAW/MIG) Also known as Metal Inert Gas or MIG welding, this process uses a thin wire as an electrode. The wire heats up as it is fed through the welding instrument and towards the welding site. Shielding gas must be used to protect the weld from contaminants in the air. Typically, this comes in the form of carbon dioxide, oxygen, argon or helium. This method is often used to work on metals such as stainless steel, copper, nickel, carbon steel, aluminum, and more. Of all the welding processes, this one is most popular across the construction and automotive industries. Gas metal arc welding is believed to be one of the easier welding techniques to learn, which makes it a great area of focus for beginning welders. It also calls for minimal cleanup, offers high welding speeds and better contro
