The hardness at the location around the weld can help evaluate the brittleness of the weld, thereby helping you determine whether the weld has the required strength, so the weld Vickers hardness testing method is a method that helps evaluate the quality of the weld.
Shandong Shannai / laizhou Laihua testis instrumentum turma scriptor Vickers duritia tius praestare duritia temptationis in partibus aut welding areas. Cum probatio duritiam a puncto Welding, multi-punctum mensuras superiores et factum est ad certum procul ex ore de sample vel summo de welding punctum. Post obtinendae multi-punctum incisum, duritiem valorem potest metiri continua mensurae et curva lacinia potest adeptus.
Cum usura a Vickers duritia testem ad test soluta partes, sequenti test condiciones notandum:
I. Platness de sample: ante testis, ut timere ad scampiam ut sit probata ad eius superficiem lenis, liberum de Oxide layer, rimas et aliis defectibus.
II. De centro linea de weld, ut a puncto in curvam superficiem omnis C mm pro temptationis.
III. Eligens alia test viribus et consequuntur in diversis results, sic oportet nos eligere oportet test vim ante tentant.
Et microchless testes est requisita ad superficiem metam de probata sample, quod indiget diligenter paratus secundum metallographic sample.
The microhardness test principle in the microhardness test method is exactly the same as the Vickers hardness, but the load used is smaller than the low-load Vickers hardness, usually less than 1000g, and the resulting indentation is only a few microns to a few two microns, so the microhardness test provides a very convenient means for studying the microstructure properties of the permeable layer. Est late solebat determinare duritiam cuiusque tempus super superficiem et in permeating layer.
Symbolum microbalum solet per HV et determinatio principium et modum similes Vickers duritia modum. Et loading ratio, mensuræ system et indenter praecisione microbortunness testes sunt magis postulantes quam humilis onus Vickers duritia. In praesens, microcholness tester est late in tenuis workpieces, et quia magnificatio pervenire CD temporibus, quod saepe usus est simplex metallographic microscopium.
In processus usus, operam debet solvit ad onus, micrometer et indenter micrometer micrometer micrometer micrometer micrometer, quod in conspectu usus, et duritia est usus ad comprehensive idem de sua significans valorem.
Et microchless tester applicat ad onus in test operationem ut lenis et uniformis quam maxime sine ictum et vibration. Ut ad accurate test results, solet necessaria ad metiretur aliquoties in diversis partibus et invenire mediocris valorem repraesentare duritiam valorem de permeability test layer aut stomachum tempus. Nam infiltration layer usus est summus temperatus, eius duritia potest metiri per usura altum temperatus microcholness testem.
