Dear Prashant ,

 

Need to Qualify the PQR as per AWS D 1:1 in 6GR position for the TKY joint and to confirm it covers your max. and min Dihedral direction plus the mock up pieces .

 

You ned to conduct the Mock up pieces which will cover your Dihedral angle as covered in 4.12.4 section of AWs D 1:1 .

 

Let me know if any more details are required ,

 

Regards,
