Application Summary AI generated
This standard specifies the qualification requirements for overlaying-welding procedures used to deposit hardfacing materials on valve sealing faces. It is applied in the manufacturing and quality control of industrial valves, particularly for ensuring the durability and leak-tightness of sealing surfaces in fluid handling systems such as oil, gas, and chemical pipelines. The standard provides a testing framework to validate welding parameters, material compatibility, and mechanical properties before production.
