Abstract

Abstract: The situation and tasks of the welding quality control during the installation process in the ultra supercritical and supercritical unit were introduced. The relationship between welding quality, construction duration and safety was analyzed. And based on the analysis and summary of lots of practical problems in the welding engineering, a set of feasible management mode was proposed. In order to ensure the quality of welding construction, the method of issuing the "welding group certificate" was recommended.

Key words: ultra-supercritical, welding engineering, quality management, welding group certificate
