A question regarding the welder qualification requirements for tube sheet corner joints
Thread Content
Hello everyone. I have been studying for the *welder certification exam recently. For codes like SMAW-FeII-6FG(K)-12/57-Fef3J, the value 12/57, according to the examination rules, refers to a weld metal thickness of 12 and an outer diameter of 57 for the pipe. So the question is: how is the weld metal thickness calculated for pipe sheet corner joints? If our factory is preparing the base material, what should be the thickness of the pipes? What is the thickness of the board? I hope everyone can give me some advice. Thank you!
Dear experts, please help me out of this dilemma. Thank you!
In my opinion, the thickness of the steel plate used should be 12 mm; for the tubes, it’s sufficient to ensure an outer diameter of 57 mm, with no mandatory requirement regarding the wall thickness of the tubes.
