Analysis of air compressor journal fracture

Abstract

Abstract:

Abstract:Based on the accident of fracture of a power plant’s air compressor journal,the author carried out macroscopic test,mechanics performance test and metallographic structure exam,and indicated that the main reason of fracture is cold crack caused by improper welding technique.The author also claimed that the poor mechanical properties accelerated the extension of the crack,and suggested that to enhance pre installed inspection andavoid repair welding if possible.
