A WPS specifies a minimum preheat temperature of 300°F. During production welding the inspector measures the base metal temperature at 275°F. What action should the inspector take?
-
A
Allow welding to proceed since the difference is within 10% tolerance
-
B

-
C

-
D
Accept the weld if final NDE passes
