摘要
Abstract
As the main load-bearing component of railway passenger trains,the bogie frame has put forward quite strict re-quirements for welding quality,and the non-destructive testing technology of its key stress welds has gradually improved.Based on the structural characteristics of railway vehicle frame products,the internal inspection process difficulties of key welds in railway vehicle frames were analyzed and solved.Ultrasonic phased array inspection was carried out on the welds,which was verified in practical testing.Ultrasonic phased array technology can accurately detect various internal defects in this type of weld seam,achieving full coverage inspection of key welds on the motor suspension bracket and brake pad sup-port suspension seat of rail vehicle bogies,realizing early detection and elimination of defective welds,and effectively ensur-ing the safety of rail vehicle operation.关键词
