What Is Arc Welding? Definition and Uses

Categories: Welding Technology

The welding industry can seem overwhelming to newcomers, but with some effort, it can become a fulfilling and comprehensible field. If you’re new to welding, you may wonder about the meaning and purpose of arc welding. The following explanation and applications will provide you with a clear understanding of this technique and its widespread popularity.

Arc welding is a welding process that uses an electric arc to melt and join metals. The electric arc is created between an electrode (which can be consumable or non-consumable) and the workpiece. The heat generated by the arc melts the metal, which then cools and solidifies to form a strong joint.

Arc welding is commonly used in the construction, manufacturing, and repair industries to join metals such as steel, aluminum, and copper. It is also used in the automotive industry to repair and fabricate parts.

There are several types of arc welding, including:

  1. Shielded Metal Arc Welding (SMAW): Also known as stick welding, this is the most common type of arc welding. It uses a consumable electrode coated in flux to create the arc.
  2. Gas Metal Arc Welding (GMAW): Also known as MIG welding, this process uses a wire electrode that is fed through a welding gun. A shielding gas is also used to protect the weld from contamination.
  3. Flux-Cored Arc Welding (FCAW): This process is similar to GMAW, but uses a tubular electrode filled with flux instead of a solid wire.
  4. Gas Tungsten Arc Welding (GTAW): Also known as TIG welding, this process uses a non-consumable tungsten electrode and a shielding gas to create the arc.

Arc welding is a versatile and widely used welding process that can produce high-quality welds on a variety of metals.
