根据 QW-451.1:
Thickness T of Test Coupon, Welded (mm): 1.5 to 10 incl.
Range of T ...
因为要冲击,适用QW-403.6.
QW-403.6 The minimum base metal thickness qualified is the thickness of the test coupon T or 5⁄8 in. (16 mm),whichever is less. However, where T is less than 1⁄4 in.(6 mm), the minimum thickness qualified is 1⁄2T. This variable does not apply when a WPS is qualified with a PWHT
above the upper transformation temperature or when an austenitic or P-No. 10H material is solution annealed after
welding. |
