Title: Understanding EN ISO 15614-4:2016 - The Ultimate Guide for Arc Welding of Tube-to-Tube Plate Joists

Introduction

EN ISO 15614-4:2016 is an essential international standard that outlines the guidelines for the qualification of welding procedures. More specifically, it focuses on arc welding of tube-to-tube plate joints in metallic materials. This standard has gained significant importance in various industries, including oil and gas, construction, automotive, and manufacturing, as it ensures the quality and reliability of welded connections. In this article, we will delve into the key requirements of EN ISO 15614-4:2016 and its significance for tube-to-tube plate welding.

What is EN ISO 15614-4:2016?

EN ISO 15614-4:2016 is an international standard that outlines the criteria for the qualification of welding procedures. It is specifically designed to address the needs of the aerospace, oil and gas, and construction industries, which require high-quality and reliable welded connections.

EN ISO 15614-4:2016 is divided into several sections, each of which covers a different aspect of welding procedures. The standard covers various welding processes, including gas metal arc welding (GMAW), shielded metal arc welding (SMAW), and submerged arc welding (SAW). It also provides guidelines for welding procedures design, welding equipment selection, and inspection and verification.

Key Requirements of EN ISO 15614-4:2016

EN ISO 15614-4:2016 has several key requirements that are essential for ensuring the quality and reliability of welded connections. These requirements include:

1. Arc welding procedures must be designed to ensure proper cooling of the weld pool and prevent distortion or distortion-induced cracking of the weld joint.

2. The welding process must be selected based on the specific requirements of the material being welded and the welding joint geometry.

3. The welding equipment must be appropriate for the specific welding process and ensure the necessary safety precautions.

4. The welding process must be visually monitored to ensure that the weld joint is within the specified tolerances.

5. The weld joint must be visually inspected for any defects or distortion, and the weld must be removed if any defects or distortions are found.

6. The welding process must be documented, including the welding equipment, welding procedures, and welding results.

Conclusion

EN ISO 15614-4:2016 is an essential international standard that outlines the guidelines for the qualification of welding procedures. It specifically focuses on arc welding of tube-to-tube plate joints in metallic materials and has gained significant importance in various industries, including oil and gas, construction, automotive, and manufacturing. By adhering to the key requirements of EN ISO 15614-4:2016, manufacturers can ensure the quality and reliability of welded connections and achieve the desired welding results..
