Welding is an incredibly important metal fabrication process that joins two components together using high heat. As you look into building and repairing equipment, understanding the different processes and techniques is a must to ensure strength and durability. Here’s a rundown on some welding techniques and their uses, so you know what to ask for at the metal shop.

Understanding Welding Techniques & Uses

Arc

Arc welding, or stick welding, is a method that uses a rod, called an electrode, that melts alongside the metal component to create a weld pool, which eventually cools into a sturdy joint connection. This versatile and common weld technique can be used with iron, aluminum, copper, nickel, and steel. The process is popular because the tasks can be performed both indoors and outdoors, in a range of weather conditions, making it ideal for mobile or construction needs. 

MIG

MIG, or metal inert gas welding, uses a spool gun and a spooled wire electrode to create a weld. At the same time, gas is released to create a shield for the area being worked on. This technique requires a controlled indoor environment since welders work with gas that can be temperamental. MIG welding is often necessary for projects with intricate designs that use stainless and carbon steel.

The final weld will look a bit neater and smoother in comparison to the arc process. However, the slightest breeze or bit of rust present can negatively impact the final product’s strength and bonding success. 

TIG Welding

Instead of a metal electrode, TIG or tungsten inert gas welding uses a non-consumable tungsten option and a filler wire that’s dipped into the weld pool to create the bond. TIG welding can be performed on nearly all metals, including steel, stainless steel, aluminum, nickel alloys, copper, and even gold. You’re most likely to see this process in intricate projects where visual appeal is a priority such as door handles, car fenders, and bike frames.
