Overview Welding Processes

  • MIG – Gas Metal Arc Welding (GMAW): MAG (Metal Active Gas) or MIG (Metal Inert Gas) welding is an arc welding process that uses continuous wire feed. It uses a shielding gas such as argon or CO2 to protect the workpiece and heat affected zone from oxygen and other airborne components. It is a commonly used process for joining metallic materials such as steel, aluminium and stainless steel. It is particularly suitable for joining thicker sheets and tubes. It is also versatile and is suitable for joining steel pipes as well as aluminium parts in the aerospace industry. It is a fast and efficient method that produces a clean and accurate weld.
  • Stick – Shielded Metal Arc Welding (SMAW): Manual arc welding, also known as manual electrode welding, is a type of electric arc welding that uses a manual electrode to weld the material. It requires the welder to manually guide the electrode to create the arc and weld. It is an older and widely used process, mainly for joining steel and other low alloyed metals. It is easy to learn, has a low initial cost and requires little equipment.
  • TIG (Tungsten Inert Gas) welding is an electronic arc welding process using a non-melting tungsten electrode rod. The arc is generated between the electrode and the workpiece to weld the material. A shielding gas such as argon or helium is used to protect the arc zone from oxygen and other air components.
  • Flux-cored arc welding (FCAW): is an arc welding process that uses a flux-filled wire. The wire, which is a hollow tube of steel or stainless steel, contains a flux that acts as a shielding gas and to clean the metal during welding. There are two types of FCAW: self-shielded (FCAW-S) and gas-shielded (FCAW-G).
  • Submerged Arc Welding (SAW)
