Abstract

Abstract: Take welding and heat treatment of the P92 steel of main steam pipe in Huaneng Yuhuan Power Plant as the example, the solutions of technical problems in novel material welding were introduced. Aiming at the problems existing in welding and heat treatment field in China, some effective measures were employed to control the installation quality. It is expected that the measures mentioned in this paper can be used as reference for welding quality control in construction of other ultra-supercritical units.

Key words: Ultra-supercritical unit, novel heat-resisting steel, heat treatment, filler metal, welding process, performance requirement, quality control
