Most Common Types of Welding

Different welding techniques incorporate varying gases and equipment. Each technique may also be defined by the characteristics of the bond it forms. The three most common welding methods include:

  • Tungsten Inert Gas (TIG) Welding. Also known as Gas Tungsten Arc Welding (GTAW), TIG welding is a versatile welding method that requires the welder to feed a tungsten rod while simultaneously operating the TIG torch. The electrode on the torch heats the metal of the workpieces, creating weld beads that cool and create a bond between the two pieces. TIG/GTAW welding requires a higher degree of technical skill than other welding methods.
  • Metal Inert Gas (MIG) Welding. MIG welding, sometimes called Gas Metal Arc Welding (GMAW), is one of the simplest and most commonly used welding techniques. This method creates extremely strong bonds while producing only a small amount of waste. With this technique, an electrode is fed through the welding gun to create an electric arc between the electrode and the base metal. The arc heats the material to its melting point to create precise welds between the two workpieces.
  • Shielded Metal Arc welding (SMAW). More commonly known as Stick Welding, this traditional welding method still sees frequent use in many modern applications. Stick welding equipment is affordable and portable and may also be used with rusted metal and other difficult materials that MIG and TIG welding can’t accommodate. Stick welding also uses a consumable electrode melted by an electric arc, though it doesn’t require a shielding gas to protect the weld puddle as it forms. Stick welding produces a layer of slag that requires removal after the process is complete but is otherwise a relatively simple welding process.
