HUANG Yachun, GAO Jungen, LIU Kaili. Analysis and improvement application of welding quality problem in electric heater parts of nuclear power pressurizer[J]. 2021,51(11):110-113. DOI： 10.7512/j.issn.1001-2303.2021.11.20.
The quality problems occur many times in the welding of electric heater parts of nuclear power pressurizer in a certain project, such as incomplete penetration of root and pits dimensions out of tolerance. In this paper, the welding quality problems of electric heater parts in pressurizer are analyzed and studied to find out the causes of defects, so as to improve the welding process or control measures, solve and avoid the recurrence of similar quality problems and ensure product quality.
