Abstract

F91 steel, a high-performance alloy, is prevalently utilized in fabricating valve bodies for operations in elevated temperature and pressure environments. Submerged arc welding (SAW), acclaimed for its efficiency and superior quality outputs, is predominantly employed in welding F91 steel. Nevertheless, the welding efficacy of F91 steel is subject to various influencing factors. This manuscript delineates an experimental investigation into the principal factors affecting the welding performance of F91 steel utilizing SAW, encompassing welding process parameters, welding materials, preheating, post-weld heat treatment procedures, and the environmental conditions during welding. Through a comprehensive analysis of these elements, this research offers insightful guidelines and reference points for enhancing production practices, thereby augmenting the quality and reliability of welding in F91 steel valve bodies.
