During the guidance process the candidate prepares a portfolio, which a committee then assesses, validating catalogue content in part or in full. If the committee is unable to validate all contents of the catalogue, it assigns tasks to the candidate for verification.
Candidates demonstrate their proficiency in manual arc welding of the TIG type in accordance with the SIST EN ISO 9606 standard (Qualification testing of welders – Fusion welding) or equivalent. The welder chooses the type of weld in agreement with the committee (butt or angle on sheet or pipe, base material group, welding position and other details regarding execution that are covered by the standard used. Practical verification lasts a maximum of 150 minutes. Verification of theoretical knowledge is done in writing and/or orally and lasts a maximum of 30 minutes. It includes verification of familiarity with the process and method of work, materials and equipment, occupational safety and health, fire safety and quality in accordance with the occupational standard for TIG welders.
Candidates demonstrate attainment of the knowledge, skills and competences defined in the catalogue of standards of vocational knowledge and skills.
Providers of procedures for identifying and validating NVQs are entered in a register of providers maintained in the collection of the national information centre for vocational qualifications. These are: vocational schools, businesses, B2B training centres, adult education centres and chambers of commerce.
Candidates may propose in their personal portfolio, as a test sample in connection with the practical assignment for verification, the type of weld (butt or angle), sheet or pipe, base material group, welding position and other details regarding the welding of the test sample, which the committee will then take into account when determining the practical assignment in the event that the candidate has to undergo verification.
