Need a Standard Procedure for NDE of Welds

My company has to submit a standard procedure/protocol for the inspection of welds via VT, MT etc. This is proving very difficult to find. If anyone can point me in the right direction I would very much appreciate it.

Is the work to be done to a known standard or specification. If so, which is it?

Hobart,

It all depends on where is this weld located or part of what! I mean, if the weld is on a pressure vessel, than the ASME Code should be the guiding criteria. Otherwise, you may use AWS D1.1 standard (American Welding Society) and if the weld is on a pressure pipe, I do believe that B31.1 should apply.

You only need to mention the specification in the standard procedure you already have
( i mean if you are an inspection company you should have a procedure for all your inspection when you started your company)
needed for a particular inspection.
If the client/operator does not specify the particular standard you can write down various standards like MIL;API; ASME;AWS D1.1;etc.
(by the way AWS does not give you a procedure on how to carry out Magnetic Particle Testing it will refer you to ASTM)
in a section in your procedure, so that whatever you are inspecting wether its a pipeline or structural weld it will be applicable to both and you dont have to write another one.

There maybe some additional information or changes required for various standards used.

Mr. Hudson,
I'm not sure if this is pertainent to your search, but I believe API (American Petroleum Institute) : API 1104 20th ed. primarily deals with the welding codes and somewhat limited Ultrasonic testing, however I dont recall much in the way of other procedures.

The reason people ask for a procedure up front is to ensure their vendor or service provider is capable of ensuring NDT (or other special processes) will be properly addressed. Throwing together a document without an in depth understanding of what is going on is not a good idea. Perhaps the answer is to not rely on a Forum of well-intended persons. Perhaps it would be best to hire or contract with a local professional to get your NDT affairs in order - it is bigger than just a procedure. You must go all the way back to the purchase documents to understand the subtleties of Code and Standards as well as the implications on performer qualifications, equipment, consumables, procedure qualification, acceptance and reporting. To be blunt, the question belies a fundamental problem - seek professional help.

If you are going to get into the NDT business you probably should hire a Level III to prepare your NDT program and procedures..That is the normal protocol.

Much of the advice you have received is spot on - you need to determine what the object of the exercise is. I see many procedure submissions poorly assembled and obviously constructed with no idea of what we as the end customer are seeking. It very often results in an immediate downrating of a company's perceived abilities.
Get a level III involved , have him look at the contractual requirements, identify the referencing docuemnts and then write a procedure that fits the requirements. Remembe rthe more complex a procedures or addressing things not required for your application can lead to propblems during performance and audit of NDE activities. Follow good QA principles get it right first time.

Im guessing the guy was doing the welding?

Probably best to contact your closest NDT provider as they will probably be doing the testing anyway?
