Understanding EN ISO 9606-4:2021

EN ISO 9606-4:2021 is a welding standard issued by the European Committee for Standardization (CEN) and the International Organization for Standardization (ISO). This technical article aims to provide an easy-to-understand explanation of this important standard in the field of welding.

The Purpose of EN ISO 9606-4:2021

The main purpose of EN ISO 9606-4:2021 is to provide guidelines for the qualification of welders involved in the production of welded structures. It specifies the requirements for testing and certification of welders, ensuring that they possess the necessary skills and knowledge to produce safe and reliable welds.

Qualification Testing Process

The qualification testing process defined by EN ISO 9606-4:2021 consists of several essential steps. First, the welder must submit their application for qualification testing, which includes providing documents that demonstrate their training, work experience, and any previous qualifications. Next, the welder undergoes a practical examination, where they are assessed on their ability to perform various welding tasks according to specified procedures. The examination is conducted by certified examiners who evaluate the welder's technique, skill, and adherence to safety standards. If the welder successfully passes the examination, they receive a certificate of qualification valid for a certain period of time.

Renewal and Maintaining Qualification

It is important to note that the qualification obtained under EN ISO 9606-4:2021 has an expiration date. Welders are required to undergo renewal testing before their certificate expires to ensure their skills and knowledge are up to date. Renewal testing follows a similar process as the initial qualification, but may involve additional requirements such as documentation of recent work experience or participation in relevant training courses. Maintaining a valid qualification is crucial for welders to demonstrate their ongoing competency and adherence to industry standards.
