Regarding welding repairs
Thread Content
I would like to ask if there are any standards for welding repairs?
There are no specific standards for welding repairs; rather, relevant requirements for welding repairs are included in various standards.
What is usually seen on-site is local grinding followed by rewelding.
In other words, there is no explicitly defined standard; it’s only mentioned in standards such as 150/151/47012?
I really can’t figure it out. . . . Why would there be specific standards for this? Is it impossible to proceed, or do you not know what needs to be revised? Still don’t know how to repair it?
I am translating a Korean repair standard, so I’m asking if there is any similar one in China
There are quality standards to be met after repair, but no standards specific to the repair process itself
There are standard ones; they come in different materials and for various uses – check the relevant standards
No, most of the regulations regarding renovations are contained within the standard manufacturing sections. The relevant information is scattered everywhere; it would be convenient to have a single overall manufacturing standard.
150.4 Manufacturing section, item 7.4 was mentioned
