QW 462 test specimens
The purpose of the QW-462 figures is to give the organization guidance in dimensioning test specimens for tests required for procedure and performance qualifications. Unless a minimum, maximum, or tolerance is given in the figures (or as QW-150, QW-160, or QW-180 requires), the dimensions are to be considered approximate. All welding processes and filler material to be qualified must be included in the test specimen.
规范中已经说明,对尺寸的要求至少一个guidance, 并不是强制要求,所以 你可以不按照19mm做。 |
