When welder need to requalify for gtaw and smaw?

Welders need to requalify for Gas Tungsten Arc Welding (GTAW) and Shielded Metal Arc Welding (SMAW) when they have been away from welding for an extended period, typically six months to a year, depending on the employer or governing body requirements. Additionally, requalification may be necessary if there are changes in the welding procedure, the welder's skill level is in question, or if new materials or equipment are introduced. Regular assessments and requalification ensure that welders maintain the necessary skills and adhere to safety and quality standards.
