We have to perfrom a qualification for this connection.
What are the required sizes for tickness of the plate and tubes.
How much tubes must be welded

The HEX is ASME VIII, Div.I

Who can help me. Thanks in advance

It's Qualification fr welder ? or Joint strength ?
I belive you will have to go back to your drawing or actual job requirement and fulfil same datas to your Mok up piece.
And yes ASME SEC VIII DIV -I ,Appendix -A can help you out for rest...
