An occupational qualification standard is a document which describes the set of skills, knowledge and attitudes, i.e. competence requirements, needed to successfully accomplish duties. Occupational qualification standards are used for compiling curricula and awarding qualifications.
A welder usually works in an enterprise that produces metal products and constructions and performs construction, installation, maintenance and repair work.
Their main job is preparing welding work, constructing structures according to technical drawings, making and performing the post-processing o...f welded joints and checking the results. Their job requires an ability to read technical drawings and knowledge of processing technology and the properties of materials.
This occupational qualification standard describes the vocational competences of Welder, Level 3.
A welder at this level can construct and weld simpler welded products, parts and building structures. They need supervising for more difficult works (requiring inspection).
Welder, Level 3 uses the following welding methods in their work: manual metal arc welding (MMA 111); and semi-automatic welding (MAG 135).
The occupational qualification standard of Welder, Level 3 includes two partial professional qualifications:
