UCS-68b(2)的轻质载荷以及角焊缝如何理解

emperor620

(2) fillet welds having leg dimensions not exceeding
3/8 in. (10 mm) attaching lightly loaded attachments, provided
the attachment material and the attachment weld
meet requirements of UCS-66 and UCS-67. “Lightly loaded
attachment,” for this application, is defined as an attachment
for which the stress in the attachment weld does
not exceed 25% of the allowable stress. All such welds
shall be examined by magnetic particle or liquid penetrant
examination in accordance with Mandatory Appendix 6 or
Mandatory Appendix 8
如上所述，在UCS-68b（2）中，轻质载荷的满足UCS-66和UCS-67的角焊缝需要进行磁粉或者PT，这个该如何理解呢，什么是满足UCS-66和UCS-67的角焊缝，什么又是轻质载荷？是不是如吊耳之类的？

连接轻载附件的焊脚高度不超过10mm,且这些焊缝需要满足UCS66&67的低温冲击要求。轻载连接的定义为焊接处应力不超过其许用应力的25%，且需要PT OR MT.

中文字面意思是这样的，不明白的是什么叫轻载附件，如何才能确定是角焊缝满足UCS66&67？

看UCS66和67吧，这样你才能理解啊

lightly loaded attachments又该怎样理解呢，哪些情况下又是 lightly loaded attachments？

lightly loaded attachments 说的很明白，这个load 引起的应力不超过许用应力的25%，
