NACE MR0175 rules are given for the qualification of a PQR for hardness requirements. Different hardness survey profiles are given for the qualification of groove and fillet welds. In ASME IX a PQR for a groove qualifies fillets for the purposes of welding code. Do hardness profiles on grooves and fillets need to be performed separately for the purposes of NACE? Do different size grooves and fillets also need to be qualified separately? My questions relate mostly to the scope of 316L material.
