If any sample weld is deficient, all welds shall be checked.

若任一取样焊缝有缺陷, 需检查所有焊缝.

If you have been careful when marking out and cutting the parts outlined on page one these parts should all line up accurately ready to weld.

如果你一直小心划出和削减第一页上的这些部分都应该准确地排队准备焊接概述的部分。

Hardness measurement on welding thermal simulated specimens and cross weld specimens showed that no softening occurred in the HAZ. All the cross weld tensile specimens ruptured in the base metal.

无论是焊接热模拟试件还是焊接接头硬度测试均表明HAZ不存在软化问题，接头拉伸试验断在远离热影响区的母材上。
