Welding code for mechanical components of PWR nuclear islands
Procedure qualification of repair welding for weld defects
1 Subject content and application scope
This standard specifies the requirements for procedure qualification of repair welding process in the design, manufacture and installation of nuclear island mechanical equipment of pressurized water reactor (PWR) power plants.
This standard is applicable to the procedure qualification of repair welding for welds of carbon steel or low alloy steel, austenitic stainless steel, austenitic stainless steel build-up welding layer on carbon steel or low alloy steel and nickel-based alloy surfacing layers.
