What happens if a welder's qualification is not maintained after a specified period?

When a welder's qualification is not maintained after a specified period, the welder must undergo the requalification process. This requirement is in place to ensure that welders maintain the necessary skills and knowledge to perform welding tasks safely and effectively. The requalification process typically involves demonstrating the ability to perform welding operations to the standards established in the initial qualification. This is important for maintaining the integrity and safety of welded joints, especially in critical applications such as pipeline construction and maintenance. Regular qualification and requalification help ensure that welders are up to date with current techniques, materials, and safety practices, which is essential in the welding industry.
