Weld clad hardness 1

[metboss]

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

As per WPS & WPQ you need to test hardness after cladding.It's mandatory in ISO 9001 as well API 6A.

Jayadeep, thansk for your input.

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 ?

Regards

what parts are you talking about? Gate, ring grooves, stem, seat pockets? API-6A has charts for most valve parts.

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!

Refer API 6A 20 TH ED. UNS N06625: 35 HRC - for latest cladding AS PER MY KNOWLEDGE.
*API CLAUSE 5.5.2 Material qualification testing.
