Abstract

The martensitic steel X10CrMoVNb9‑1 is widely used in high temperature components in power plants where strict welding and post weld heat treatment (PWHT) requirements are important to ensure long term safe operation. International standards and technical regulations define different qualification criteria for welded joints and PWHT parameters. This paper presents a comparative analysis of the requirements specified in ISO 15614-1 and VGB-S-013 guidelines for the qualification of welded joints in X10CrMoVNb9-1 steel. The analysis focuses on PWHT temperature ranges, holding times, acceptance criteria for mechanical properties and overall welding procedures specifications. The paper highlights how varying normative approaches can influence the qualification of welded joints in power plant components and provides practical insight involved in welding procedure selection and approval. The presented study provides a foundation for further investigation of the metallurgical and mechanical properties resulting from the standard that defines welding procedure specifications and technical regulations requirements.
