    What is a coded welder?

    A coded welder is a welder who has passed practical examinations in a specific welding configuration, enabling them to hold a certificate that proves their ability to undertake welding to industry standards. The examination is known as the Welding Approval Test.

    How long does coded welding last?

    A coded welding certification must generally be signed every six months by a qualified person as validation the coded welder is keeping to standards. A coded welder must also retake an exam every two to three years.

    What are the main types of welding?

    Some of the most common methods of welding include: 


    • MIG - also known as gas metal arc welding, MIG welding uses a continuously-fed electrode and shielding gas to weld
    • TIG - commonly known as gas tungsten arc welding, TIG is a similar process to MIG, however uses a much stronger tungsten electrode
    • Stick - shielded metal arc welding, or stick welding, uses a stick which melts as an electric arc is passed through
    • Flux-cored arc welding - flux-cored uses a continuous electrode filled with flux to join metals
