关于ASME动力锅炉敲打焊工钢印的问题

minminsaid

最近正在修订ASME程序文件，关于ASME动力锅炉敲打焊工钢印有个疑惑，敲打的位置肯定实在焊缝附近，可是对于间隔有规定吗？原来公司原规定不大于1000mm，我参考其他公司最新版本要求的是不大于900mm，我想知道这些数据的出处，请大家指导下！！！
已在PW-28.4.1找到数据支撑，谢谢

公制是 1000mm, 英制 3ft。

出处在 PW-28.4.1 The Manufacturer shall also establish a
procedure whereby all welded joints, except as permitted
in PW-28.4.2 and PW-28.4.3, can be identified as to the
welder or welding operator who made them. This
procedure shall use one or more of the following methods
and be acceptable to the Authorized Inspector. The welder
or welding operator may stamp his identification mark on
or adjacent to all welded joints made by him, or he may
stamp on or adjacent to a continuous weld or a series of
similar joints made by him at intervals of not greater
than 3 ft (1 m), or, in lieu of stamping, the Manufacturer
may keep a record of welded joints and the welders or
welding operators used in making the joints.

900mm 是 3ft 换算过来的，但应该用 1000mm。

要求是小于3ft，但实际操作一般控制在100mm以内
