It frames the work of the person who performs welding by addressing the occupation’s definition, classification, the tools, materials and equipment used, and the knowledge and skills expected in the role. Welding is a technical joining field in which metal parts are combined through heat and/or pressure, so correct equipment selection and core occupational competence are central to the work.
