Title: Understanding EN ISO 17638: 2016: A Technical Standard for Visual Testing of Fusion-Welded Joints

Welding is a vital process in various industries, including manufacturing, construction, and transportation. Ensuring the quality and integrity of welded joints is critical for ensuring the safety and functionality of the systems or products they serve. To achieve this, various industries have developed technical standards to provide guidelines for visual testing of welded joints. EN ISO 17638: 2016 is one such standard that provides a comprehensive framework for conducting visual inspections of welded joints.

EN ISO 17638: 2016 is a technical standard that defines the requirements and methods of visual testing of fusion-welded joints. It provides guidance on the performance, safety, and durability of these joints, ensuring their effectiveness in providing support and comfort for wheelchair users. The standard establishes specific criteria and acceptance levels for assessing the imperfections based on their type, size, and location.

Key Elements of EN ISO 17638: 2016

EN ISO 17638: 2016 provides a framework for visual testing of welded joints by establishing specific criteria and acceptance levels for assessing the imperfections. The standard defines four key elements:

Visual inspection

Visual inspection is the method of testing welded joints by visually inspecting their surface for imperfections. The standard provides guidelines for the type of visual inspection, the equipment used, and the acceptance criteria for assessing the results.

Assessment of surface imperfections

The standard defines the criteria for assessing the surface imperfections, such as cracks, porosities, and discontinuities, based on their type, size, and location. It also provides guidance on the interpretation of the results and the communication of the findings.

Acceptance criteria

The standard establishes specific criteria and acceptance levels for assessing the surface imperfections based on their type, size, and location. It also provides guidance on the testing process, the equipment used, and the documentation of the results.

Test methods

The standard provides guidelines for the testing methods used to assess the surface imperfections, including the equipment, the testing conditions, and the testing procedures. It also defines the criteria for the test results and the acceptance of the results.

Conclusion

EN ISO 17638: 2016 is an essential standard for visual testing of fusion-welded joints. It provides a comprehensive framework for assessing the quality and integrity of welded joints, ensuring their effectiveness in providing support and comfort for wheelchair users. By following the guidelines and criteria provided in EN ISO 17638: 2016, manufacturers can ensure that their welded joints meet the required standards for safety and functionality
