According to the above requirements, in the process of welding process assessment, the following must be able to ensure the purpose of assessment:A must be tested with the ordered steel tubes used in the project.Because although be, X70 steel tube level, in fact, each manufacturer meet grade X70 steel chemical composition and processing in a different way, delivery condition is different, so using someone else's welding procedure qualification, and the engineering use of steel tube test, the test results are difficult to prove the engineering use of welding process meets the quality requirements of this project.
