Scope: This part specifies basic requirements such as welding documents, pre-verification, assessment and acceptance, welding data package and welding process specifications, and material weldability of nuclear is and mechanical equipment in pressurized water reactor nuclear power plants. Heat treatment during the welding process, welding joint testing, specimens and Evaluates general requirements for the preservation of joint and product welding witness documents, qualifications of welders and welding operators, and provides prescriptive requirements for mechanical property testing of welded joints, classification of metal fusion welding defects and branch pipe forms - welded joints recommended for pipelines . This section is applicable to the welding and surfacing of carbon steel, low alloy steel, austenitic stainless steel or austenitic-ferritic stainless steel, and nickel-based alloys during the manufacturing process of nuclear is and machinery and equipment in pressurized water reactor nuclear power plants.
