Resumen

Small and medium size stocked components intended for boiler and pressure vessel are often manufactured and welded with reference to ASME section III and IX. This paper mainly focuses on rules for welding qualification, monitoring welding activities during manufacturing and the extent of supervision by independent inspection body required by the quality system. In this work comparison required for welder procedure qualification as well as welder qualification accordance with procedure qualification record is carried out. Finally, range of qualified will decide the welder qualification based on WPQ and PQR.Cite this Article Shah Sagar I, Shah Jinesh B.
