Thanks for your support.
Regarding PWHT of 3 cycles.
Below I have mentioned my PQR ranges for PWHT.
POST WELD HEAT TREATMENT( QW-407)
TEMPERATURE RANGE 630 ±10° C
SOAKING PERIOD 190Min
HEATING RATE 190°C/Hours Max
COOLING RATE 190°C/Hours Max.
As per the above range, it's qualified 3 cycles, but how? and for 3 Cycles PWHT where I required test coupons? how many coupons tests shall I have conduct?
Please clarify my above query in detail with code.
Thanks once again.
Kiran
