Issues regarding test pieces for the evaluation of tube sheet welding processes
Thread Content
Welding procedure qualification for φ10x1.25 pipes welded to 20-mm-thick plates as tube sheets: According to the standards, two pipes along a diagonal should be selected and cut open to inspect 8 cross-sections. May I ask how exactly a tube sheet specimen with 10 tubes should be cut? It would be best to include diagrams. Thank you
