不同板厚对接焊

edwin

不同板厚对接焊如果板后差超过3mm，要开削斜过度。板后差正好3mm的要开过度吗？那个规范里可以找到相关的规定？

削     规范上是da于等于3把?

规范中材料部分有规定，板厚差大于或等于3mm时，削斜过渡，按照1：4的比例。

LS正解！

又可以颓废

也有的标准中的比例是1：3
好像日标就是1：3
其他标准大多是1：4

以前我们做的时候好像CSQS上说是1：4但是后来公司质量部又发了份说是1:3，真有点难为人啊，不过感觉问题都不是太大。

如果没记错的话LR规范上应该是大于3,削斜1:3.但是国内很多厂把等于3也做了削斜过渡,而且削斜1:4.不过最终都要现场验船师满意

4.4.2Abrupt change of section is to be avoided where plates of different thicknesses are to be butt welded. Where the difference in thickness exceeds 3 mm, the thicker plate to be welded is to be prepared with a taper not exceeding one in three or with a bevelled edge to form a welded joint proportioned correspondingly. Where the difference in thickness is less than 3 mm the transition may be achieved within the width of the weld. Difference in thickness greater than 3 mm may be accepted provided it can be proven by the Builder, through procedure tests, that the Rule transition shape can be achieved and that the weld profile is such that structural continuity is maintained to the Surveyor’s satisfaction.

见过很多是1:4，也有3的
