无损检测模拟试块的制作与管理

On Making and Managing Non-Destructive Testing Stimulation Samples

无损检测模拟试块的制作要综合考虑检测方法的适应性、焊接缺陷的代表性、试块重复使用要求及制作成本等因素,针对不同的检测方法专门制作。材料选择以常用易得为原则,尺寸确定以适应相关检测方法操作为好,不宜过大。试块形状和制作方法应参照被检测设备的设计生产要求确定,试块制作完成后应编号分类存放,并进行必要的防腐处理,防止其锈蚀失效。

Making non-destructive testing stimulation samples requires overall considering adaptability of testing method,representativeness of weld defect,requirement for repeating operation and making cost,and specially making them aiming at different test methods.The materials should be easy to get and making size subject to the operation of correlation testing method.Samples shape and making method should be in accordance with the demand for tested devices in design and production.The completed samples should be arranged by categories according to their numbers and treated with anti-corrosion.
