Webthe cross weld Charpy test (CWCT) was devised (Fig. 2B). The CWCT uses a conventional Charpy-V notch spec imen except that the weld plane is perpendicular to the fracture plane to force the fracture to pass through all zones of the weld. The fracture appearance of the various weld zones as measured with a binocular micro Web6 inch, schedule 40 pipe. (168.3mm outside diameter x 7.11mm wall thickness) Standard test temperature. (for Grade 6) -45°C. Charpy V-notch width: 5mm. (max. size that can be taken) Table 6 of ASTM A333 specifies a test temperature reduction of 4°C below the specified test temperature for Grade 6 because the material thickness is nominally 7mm.
