How often must a welder perform one weld in the same procedure to maintain certification?

To maintain certification, a welder must perform at least one weld using the same procedure every six months. This requirement ensures that the welder remains proficient in the technique and adheres to the quality standards set forth in the industry. Regular practice not only helps retain skills but also keeps the welder familiar with the specific parameters and challenges associated with that welding procedure.

By performing a weld within this timeframe, the welder can demonstrate their ability to produce sound welds and continue to meet the criteria necessary for certification. This practice is important in high-pressure piping applications, where the quality and reliability of welds are critical to safety and structural integrity.
