ELEMENTARY COMPETENCY 3

2. Purpose Of Inspection Coran :
Looks after grade, quality and the good of product coran must be guaranteed by way of dissociating failing product
Emphasis of expense of given the in advance defect product
Engineering retouching, according to data gotten from inspection and experiment, so that quality and perfectible making engineering

4. A. Inspection of External Defect
s invalidism is not at part of core of metal.
Often happened at steel that has passed heat treatment process where happened strain in a real height or the happening of orthogonal transformation process of uneven sewer structures ( non qilibrium)

6. External Inspection With Die Penetrant
Inspection of external defect with die penetrant is way of inspection of easiest defect and quickly, although still require visual accuracy to determine its(the position and invalidism

7. Element of Material die penetrant
Cleaner
Developer
Penetrant
Teknologi dan Rekayasa

8. Cleaner is functioning cleaner fluid to clean impurity from equiamplitude surface of work substance
Penetrant namely element of fluid having smooth crystal so that if it is sprayed equiamplitude surface of pervasive work substance into car aperture
Developer that is forcing fluid releases fluid penetran from within equiamplitude surface car aperture of work substance

9. Step Of Inspection Die Penetrant
Arranges in layers equiamplitude surface of work substance with fluid penetran, lets it is a few moments that the penetran layer soaks into car aperture. After drought rest of penetran is cleaned with cloth

10. Step Of Inspection Die Penetrant
Lets it is a few moments. with lighting of ultraviolet [light/ray]
Secretory penetran from car aperture would seems to be equiamplitude surface of like shown to drawing 3

12. Sinar X X-ray called as also [light/ray] rontgen,
Inspection carefully so can show form and position of defect in is including invalidism outside backside or under equiamplitude surface.

13. Spectro Magnetic
In principle usage of this method in defect inspection in is flow force magnetic to get through work substance. This obtainable magnetic Force from metal that is in permanent has magnetic force or magnet which is made with electrical source of power depended form of substance which will be investigated
Teknologi dan Rekayasa

14. Mode Of Action Spectro Magnetic
Magnetic field orbit will flow through work substance from direction of pole which at the oposite
The magnetic force would always is concentration of in each its(the pole, where is tip of magnetic metal

15. Happened defect or car in cutting magnet dislocation stress field line would be pole magnetic which is new
So if it is spread particle from metal magnetic, hence the particle will gather at division where there is car

16. Ultrasonic
Defect inspection in with Ultra Sonic is processing defect inspection in which more accurate and safe, need to be paid attention that defect inspection with X-ray has dangerous influence causing its(the process is must be done in room isolates to avoid danger of radiation

17. Inspection Basis Principle In With Utrasonic
Transmits high frequency noise into work substance with director so-called probe
This noise will come into work substance ( test piece) so piercing equiamplitude surface wall of work substance is backside [by]

18. Result will be presented in the form of curve at tube catode
Speed difference of noise from source of noise because pursued by equiamplitude surface of substance worked hence will generate transitter sound wave so-called Transmiter-echo
Result will be presented in the form of curve at tube catode

19. Metallography ialah suatu cara pemeriksaan pada
microstructur dari bahan logam untuk mengetahui keadaan struktur
bahan tersebut dalam hubungannya dengan sifat bahan tersebut
sebelum atau sesudah proses perlakuan panas

20. Inspection Steps of Metallography
Draws up specimen from material type which will be investigated its(the Struktur, material enabling cut of the size more or less Ø 20 x 15 mm smoothed down and refined to be finite free of incision ex- chopping
Process hereinafter is etching namely abrasion by using chemical solubility as according to material type which will be investigated
