Re: [MW:32774] PWHT and Hydrotest

Dear sahil ,

As per ASME UW -42 (Surface weld build up) , 

1. You should have qualified procedure for Butt Joint.

2. If you performed Buttering than you should go for NDT (Either MPT or LPE Test) on buttering area .

For Hydro Test ,

As per UG - 99 ,Hydro Test shall be performed after completion of all the fabrication work & NDT work .

You again need to perform Hydro Test to comply code requirement.

For PWHT ,

Please provide Material Grade for further detail.
