Nedestruktivní zkoušení vnějšího návaru na hřídeli

Abstract

The thesis focuses on non-destructive testing in heavy engineering using the method of magnetic particle and ultrasonic inspection. These methods are used to test a shaft with welded deposit for a hydraulic power plant according to standards ČSN EN 11666[11], ČSN EN 10 228-1 [13], and ČSN EN 10 228-3 [20]. Martensitic welding and subsequent non-destructive testing of the weld deposit on part of the body of the shaft diameter are carried out. In this case, we will use arc welding under welding flux and for the non-destructive testing then a magnetic field of alternating current and impulse reflection method with a double probe.
