Weld clad hardness
Weld clad hardness
(OP)
Hi all,
We are going to manufacture Wellhead equipment with cladded internals(API 6A/Base metal AISI 4130 + Inco 625 cladding).
As per API 6A, hardness testing on cladded surface is required for welding procedure qualification only whereas client is instructing us to carry it on production part cladded surface.
My question is “Does hardness testing is mandatory for cladding after production as per API 6A ?”.
Regards

RE: Weld clad hardness
I am referring to clad hardness requirements on production parts. Could you please give some reference on ISO or API clause which stipulates such requirements ?

RE: Weld clad hardness
You state that the customer is reqiring a certain test, and you ask if this is mandatory. What are your real consideration: do you want to check details on how and where (procedure details), or do you want to check if it has to be done or not as mandatory as a part of a standard?
Comment on the last part: if it is not 'mandatory' but described as a requirement in the original request for a bid, it has to be done anyway.
Please clarify!
