Re: [MW:10137] Minimum length for RT examination for PQR & WPS? ASME Sec 9?

Dear Mr. Srinivas,
 
PQR qualification is for material properties,electrical parameters ets..... and hence the material required as per the standard ex: 02 tinsel,04 bends,01 macro,impact,which is clearly mentioned in all most of all the codes related to welding with figures,
 
Welders performance qualification is totally deferent, which is based up on approved PQR/WPS, minimum weld length must be 150 mm, maximum depends up on the requirement, so do not mix up the PQP and WQT.
 
Regards
