Newbies asking for advice: Regarding the problem of reinforcing the opening of the nozzle that is not fully penetrated by ASME

When welding the nozzle and the flat cover, it is impossible to achieve a full penetration structure due to structural reasons. Do we need to include the nozzle reinforcement A2 in the opening reinforcement calculation, A1+A2+A41>A or A1++A41>A?

If it is calculated according to ASME, your diagram is wrong. There is a calculation method in ASME-Ⅷ.

Could you please tell me which chapter the calculation method is in?

Take a look at UG-16, and the 2007 version has calculation examples. You can follow it to learn calculations. ASME's weld strength is required to be calculated, which is different from GB/T150. GB/T150 requires that the welding joint type be selected according to the standard and does not need to be calculated.
