Presentation theme Nondestructive testing of career and construction

Presentation theme: Non-destructive testing of career and construction technique Hitachi Construction Machinery.

Non-destructive testing – is the insertion of an object reliability, and it’s different elements of structure, by methods that non destroy integrity and non decrease operation properties of an objects. There are nine basic types of non-destructive testing methods that bases on different physical phenomenon’s: • - radio wave method; • - electrical; • - ultrasonic testing method; • - eddy current method; • - magnetic-powder method • - thermal; • - x-ray method; • - dye penetrant inspection method; • - visual inspection method.

Types of non-destructive method that Eurasian Machinery uses. Eurasian Machinery company, as official dealer of construction and career technique manufacture Hitachi, for non-destructive testing use several method, shown below: • Visual inspection method. • Dye penetrant inspection method. • Ultrasonic testing method.

Visual inspection. We haveinspection original regulatory technical for each Visual – is one and of the opticaldocumentation type non-destructive type of technique. testing methods. It based on getting information of a testing object during visual inspection or with using support optical devices and measure tools. Eurasian Machinery company do visual inspection of a technique regular, during technician support period, during assembly process, operation maintenance and overhauls. Visual inspection act according to product factory’s regulatory and technical documentation and many years of technician support and overhauls experience career and construction technique Hitachi.

Dye penetrant inspection – non-destructive testing method, based on penetration of specific liquid substances into object’s surface defects under the action of capillary pressure, as the result defect area surface becomes color contrast to other inspecting surface. Dye penetrant inspection process including 5 stages : 1 – pre cleaning surface. 2 – penetrants applying. 3 – penetrants surplus removing. 4 – developer applying. 5 – inspection.

Dye penetrants inspection in Eurasian Machinery technicians doing dye penetrant inspection of technique’s parts and units during overhauls and maintenance process. Inspection doing with using high-sensitivity Chemetall kits that has international standards approve: DIN EN ISO 3452 -2 II sensitivity class, AMS 2644 и ASME. Detection of defects with minimum disclosure width is 1 – 10 micron.

Ultrasonic testing. We have scheme Ultrasonic Principal original testingof - regulatory method, factory’swhich recommended and use technical high frequency ultrasonic documentation sonic testingwave for method. each beams type goes of through material for inner and surface defects detection. Sonic waves goes technique. through material with some energy loses (damping) and reflect form surfaces. Reflected beam (flaw echo) gets and analysis, for measure defect existence and position. UT is effective in detecting gas pores, chemically composition difference (slag impregnation in metal) and detecting the presence of non-metallic elements. Eurasian Machinery company use product factory’s recommended ultrasonic testing methods.
