[MW:10929] SOCKET WELDS

Dear experts,
 
                  We have contractor who is suppose to carryout some repair welding for 1/2" piping schedule 160 and the material is  A106 Gr B. Due to unavailability of material they wanted to have socket welds but the existing welds is butt welds. can we allow them to have socket welds? if yes, will socket welds have the strength as butt welds? I have to give ITP also. What should I give in the ITP?
 
Kindly I need your valuable inputs.
 
Regards
Ilangkumaran
