Regarding weld flaw detection

Thread Content

How are the dimensions for photos taken in radiographic inspection specified, and which standard can provide this information?
Reply #22009-03-31
It seems that the specifications for the radiographic films used in weld inspection are divided into two types: one is a large sheet with a length of 300 mm, and the other is a small sheet with a length of 150 mm. It’s not clear which standard governs these specifications; I’m sorry about that:lol

From JB/T4730-2005 \"Non-destructive testing of pressure equipment\"; this refers only to the film, with its effective length determined according to the relevant standards, and it is also related to the photographic method and specific conditions

It is specified in detail in JB/T4730-2005
