2. What are the different types of arc welding?

Shielded metal arc welding (SMAW)

  • Also known as stick welding, SMAW is a manual arc welding process that uses a consumable electrode.
  • The electrode is coated with a flux that shields the weld from the atmosphere and produces a slag that protects the weld from oxidation.

Gas metal arc welding (GMAW)

  • Also known as MIG welding, GMAW is a semi-automatic or automatic arc welding process that uses a continuous solid wire electrode.
  • The electrode is fed through a welding gun and a shielding gas is used to protect the weld from the atmosphere.

Gas tungsten arc welding (GTAW)

  • Also known as TIG welding, GTAW is a manual arc welding process that uses a non-consumable tungsten electrode.
  • The electrode is held in a welding torch and a shielding gas is used to protect the weld from the atmosphere.

3. What are the different types of gas welding?

  • Oxy-acetylene welding (OAW) is a gas welding process that uses oxygen and acetylene gases to produce a flame.
  • OAW is used to weld a wide variety of metals, including steel, stainless steel, and aluminum.
  • Other gas welding processes include oxy-hydrogen welding (OHW), oxy-propane welding (OPW), and air-acetylene welding (AAW).
