Re: [MW:18565] PWHT range for WPS

1. You need to mention what type of material and P. No. it belongs to.

2. Whether Impact test is specified or not as per design conditions.

Subject: [MW:18561] PWHT range for WPS

Dear Experts

Can anybody explain me following about WPS & PQR as per ASME sex IX.

If my PQR qualifed with soaking temperature 630 deg. C to 650 deg. C and soaking time 2 hrs 30 minutes maximum, so my question is can WPS qualify for temperature range 600-620 deg.c or above 650 deg.c and soaking time 3 hrs or 2hrs.

My question for which temperature range or soaking time range I can use for WPS if my PQR qualified as per above mentioned PQR range ?.

Thanks in advance

Thanks

Ram
