冷弯试验

如图呈V字形，两边各1mm,按照QW163，沿着凸面任何方向开口缺陷不得超3mm，我可以判定这个为合格吗？

QW-163 Acceptance Criteria — Bend Tests
The guided-bend specimens shall have no open discontinuity in the weld or heat-affected zone exceeding 1⁄8 in. (3 mm), measured in any direction on the convex surface of the specimen after bending.
V字形 open discontinuity ，两边各 1mm=2mm， 按照 QW163 ，no open discontinuity in the weld or heat-affected zone exceeding 3 mm 可以判定这个试样弯曲试验为合格。
但是，要试验报告应写上该试样有 2mm 裂口，结果是合格。

还有如果是断在边口的话应该是直接算不合格了吧
