How often must a welder who works on pressure tanks be requalified?

The requirement for requalifying welders who work on pressure tanks is based on safety and quality assurance standards in the industry. The correct answer, which states that requalification is necessary every year, aligns with the protocols set by regulatory bodies such as the American Welding Society (AWS) and other relevant codes. This annual requalification ensures that welders maintain their skills and are up to date with the latest techniques and safety practices.

Doing so reduces the risk of failures or accidents associated with poorly executed welds in pressure tanks, which can lead to significant safety hazards. It ensures consistent quality in welding practices, which is critical for the integrity of pressure vessels used in various industrial applications. By having a structured requalification schedule, the industry can ensure that all welders continue to meet the necessary standards of competency in their work.
