The outside of the bent portion shall be free from any cracks. Where there is no provisio
28、n for bending in the standard of the cladding metal, the surface bend test may be omitted. Further, where there is no provisions for bend- ing in the standard of the base metal, the root bend test may be omitted. In any case, if requested by the purchaser, a bending test shall be executed with the i
29、nside radius of bend generally 2 times or over the overall thickness. There shall not be any cracks 3 mrn or over in length on the outside of the bent por- tion. The side bend test may substitute for the surface bend test. In the side bend test, there shall not be any cracks 1.6 mm or over in length
30、 on the outside of the bent portion. This property shall be applied to the clad steels of 6 mm or over in overall thickness and 1.5 mm or over in thickness of cladding metal. 7 Bonding condition Clad steels shall be tested in accordance with clause 14 and the bonding condition by ultrasonic testing
31、shall be as follows: a) The bonding condition of the clad steels by ultrasonic testing shall be as given in table 3. Range of flaw detection Length and area of non-bonded part Table 3 Bonding condition Grade F Overall surface detection The length of one non-bonded part shall be 50 mm or under and th
32、e area of one non-bonded part shall be 20 cm2 or under, and the total area of non- bonded parts shall be 1.5 % or under of the overall area of the clad steel. s Detection shall be conducted on the longitudinal and lateral lines of 200 mm pitch, and within 50 mm from or within 25 mm (to both directio
33、ns) from the prearranged grooving line as centre. The length of one non-bonded part shall be 75 mm or under and the area of one non-bonded part shall be 45 cm2 or under, and further the total area of non-bonded parts shall be 5 % or under of the overall area of the clad steel. b) The grades of bondi
34、ng condition by the ultrasonic testing shall generally be F for class 1 and S for class 2. However, the combination of S for class 1 and F for class 2 may also be designated, as specifically agreed on between the pur- chaser and supplier. The bonding condition of the buildup welded clad steels by th
