What is EN ISO 9606-4:2021?

EN ISO 9606-4:2021 is a standard that provides guidelines and requirements for the qualification of welders for thermoplastics. In this article, we will delve into the technical aspects of this standard.

The Importance of Welder Qualification

Welder qualification plays a crucial role in ensuring the quality and integrity of welded thermoplastic products. It verifies that a welder possesses the necessary skills, knowledge, and techniques to consistently produce sound and reliable welds.

EN ISO 9606-4:2021 outlines the process of welder qualification, including specific requirements for various welding positions and joint configurations. By adhering to this standard, companies can ensure that their welders are competent and capable of meeting the specific demands of their applications.

The Qualification Process

The qualification process outlined in EN ISO 9606-4:2021 includes several essential steps. Firstly, the welder must undergo a visual examination to assess their general fitness for welding. This examination includes evaluating their eyesight, color vision, hand-eye coordination, and general physical abilities.

Next, the qualified welder must demonstrate their skills through practical tests. These tests involve welding various joint configurations using specific welding techniques. The welder's performance is then evaluated based on criteria such as weld appearance, strength, and aBS ENce of defects.

Ensuring Compliance with EN ISO 9606-4:2021

To ensure compliance with EN ISO 9606-4:2021, companies must establish effective welding procedures and provide appropriate training and supervision for their welders. Regular requalification is also necessary to account for changes in welding technology or emerging industry standards.

Furthermore, documentation plays a crucial role in demonstrating compliance with the standard. Records of welder qualifications and test results should be maintained and made readily available for inspection.

In conclusion, EN ISO 9606-4:2021 is a vital standard that ensures the competence and proficiency of welders in thermoplastic welding. By following the guidelines outlined in this standard, companies can have confidence in the ability of their welders to produce high-quality, reliable welds. This ultimately leads to safer products and increased customer satisfaction.
