Welding is the process of joining metal together using a combination of heat and pressure until both elements become molten. Yankee sheet metal makes use of TIG and MIG welding, two electrical arc welding processes.

TIG + MIG: what’s the difference?

While both TIG and MIG welding generate heat through the use of large quantities of electrical energy, what differentiates the two is the type of gas shield they use  Each respective gas shield ensures that unwanted interaction is prevented, meaning your weld is left uncontaminated.

TIG Welding: The Basics

TIG = tungsten inert gas AKA gas tungsten arc welding (GTAW)

The TIG process uses an electric torch and filler rod that is hand fed into the molten puddle.” A foot-operated control allows the welder to slowly increase and decrease the heat during the welding process, preventing brittle metal that results from temperature shock.

MIG Welding: The Basics

MIG = metal inert gas AKA gas metal arc welding (GMAW)

The MIG process involves a metallic wire being fed into the welder. This process offers a level of flexibility through the use of manual heat settings that allows you to get the proper amount of power suitable to your project. This type of electrical arc welding is often preferred because – with adequate preparation – is relatively simple to learn.
