缺陷试板制作

dwy000

需要制作RT、UT、MT、PT缺陷试块，经典缺陷，如裂纹、未融合、未焊透，ASME演示用，有经验的指点下，谢谢！

这个非常不容易做，好像有专业做的，自己做的话成功率太低了

没错，这个国外有标准射影片给人家作训练用，很贵。但dwy000坛友有这个想法就给他鼓历一下。

当然知道有卖的，济宁模磨具厂就能做，就是贵啊，公司舍不得，才想自己做了

The method to be used for the production of defect plate may be slightly tricky. Hope, following steps may provide a defect plate.

•        Select relatively thick steel plate
•        Root opening should be too narrow in some places and too wide in some places.
•        Select an inexperienced welder or an experienced welder who knows to make mistakes deliberately.
•        Use damp higher carbon ferritic electrode (high strength) with bit sulphur content.
•        Do not preheat before welding
•        Welding position may be overhead or vertical up
