EEMUA publishes second edition of tube end welding recommendations

Engineering Equipment and Materials Users Association (EEMUA) has published edition 2 of EEMUA 143 recommendations for tube end welding. It takes ISO 15614-8:2016, Specification and qualification of welding procedures for metallic materials – Welding procedure test – Part 8: Welding of tubes to tube-plate joints as the primary source, with additions where the standard requires further clarification or does not address the topic sufficiently.

These include the constrictions of use of each joint type; requirements and practicalities for testing procedures and qualification of welders; recommendations for the preparation of tubes and tube plates; guidance on maximum preheat and interpass temperatures; and additional controls on welding parameters and on the Inspection and Test Plan.

The recommendations help identify the appropriate techniques for and limitations of tube end welding. They typically are used by procurement engineers, specifiers, designers, and materials engineers.
