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

The hardness requirement was regulated on NACE MR0175 for weld overlay to check on base metal, HAZ, and clad metal.
In general, hardness measurement act as assurance & simple verification either PWHT process after overlay has been done correctly,
prior to be machine into final dimension. CMIIW.
