What are S and T classifications used for?

The S and T classifications specifically relate to the categorization of welders based on their proficiency and the positions they can effectively work in. The designation helps in identifying the capabilities and skill levels of welders, which is crucial in determining whether they meet specific industry standards for given tasks or projects.

This classification system is important for ensuring that welders are matched with the appropriate welding techniques and positions that align with their abilities, ultimately impacting the quality and safety of the welding work. This framework allows employers and certifying bodies to assess whether a welder is qualified for a particular role or job function based on standardized criteria, thereby promoting high standards in welding practices.
