Difference Between MIG Weld & TIG Weld


Modern welding was developed in the late nineteenth century and was often used by the military. There are many types of welding nowadays and it is used in many fields, including the automotive industry. Each type of welding has its own benefits and purpose. MIG welding and TIG welding are two types of welding that utilize gas to block gases that may harm the welding pool.


Metal inert gas (MIG) welding, also known as gas metal arc (GMAW) welding, was developed during World War II as a way to produce weapons and equipment more quickly. MIG welding uses an arc of electricity that creates a short circuit amidst a constant anode and a cathode. The short circuit produces heat and a non-reactive gas. This melts metal, enabling it to be mixed together. After the heat is removed, the metal cools down and then solidifies, creating a new fused metal. This type of welding can be done either semi-automatically or automatically. Automatic MIG welding can be done with a robotic arm, while a person is needed to guide the gun during semi-automatic welding.
