Ubulukhuni endaweni ezungeze i-Weld bungasiza ukuhlola ubucwebe be-weld, ngaleyo ndlela kukusize unqume ukuthi ngabe iWeld inamandla adingekayo yini, ngakho-ke indlela yokuhlola kanzima ye-Weld Hardness kuyindlela esiza ukuhlola ikhwalithi ye-weld.
UShandong Shancai / Laizhou Laihuing Instructure Cound Perceners Hardness Hurness Hurneness Hurneness Hurneness Hardness Conser angenza ukuhlolwa kanzima ezingxenyeni ezinama-welded noma ezindaweni zokufafaza. Lapho uvivinya ubulukhuni bendawo ye-welding, izilinganiso zamaphoyinti amaningi zizokwenziwa ngebanga elithile ukusuka emaphethelweni wesampula noma ngaphezulu kwephuzu le-welding. Ngemuva kokuthola i-induction yamaphoyinti amaningi, inani le-Hardness Liven lingalinganiswa ngokulinganisa okuqhubekayo kanye negrafu yejika ingatholakala.
Lapho usebenzisa umhloli we-hervers we-Vickers Hardness ukuze ahlole izingxenye ezinama-welded, izimo zokuhlola ezilandelayo kufanele ziphawulwe:
1
2
I-3. Ukukhetha amabutho ahlukene wokuhlola kuzoholela emiphumeleni ehlukile, ngakho-ke kufanele sikhethe amandla okuhlola afanele ngaphambi kokuhlolwa.
Umhloli weMicrohardnessnessness unezidingo zokuqedwa komhlaba wesampula elihlolwe, elidinga ukulungiswa ngokucophelela ngokuya ngesampula ye-metallographic.
Umgomo wokuhlola we-Microhardness endleleni yokuhlola i-Microhardness ufana ncamashi nolukhuni lwabaviki, kepha umthwalo osetshenzisiwe mncane kuno-1000g, ngakho-ke ukufundwa okumbalwa kunama-microns ambalwa ama-microns amabili, ngakho-ke i-MicroHardness Test inikeza izindlela ezilula zokufunda izici zesendlalelo se-mistroable. Kusetshenziswa kabanzi ukunquma ubulukhuni besigaba ngasinye ebusweni nakwisendlalelo se-permeating.
Uphawu lwe-microharness luvame ukuvezwa yi-HV, kanye nemigomo yalo yokuzimisela kanye nendlela kufana nendlela yokuqina kanzima ye-Vickers Hardeness. Uhlelo Lokulayisha, uhlelo lokulinganisa kanye nokunemba kwe-indenter of MicroHardness Tenter kufunwa kakhulu kunaleso sombukisi wezinkulungwane zomthwalo ophansi. Njengamanje, umhloli we-microhardness usetshenziswa kabanzi emisebenzini emincane, futhi ngoba ukukhuliswa kungafinyelela izikhathi ezingama-400, kuvame ukusetshenziswa njenge-microscope elula ye-metallographic.
Enqubweni yokusebenzisa, ukunakwa kufanele kukhokhwe emthwalweni, i-micrometer kanye ne-indenter of the umhloli we-microhardness tester, okufanele ihlolwe ngaphambi kokusetshenziswa, futhi i-hardness block isetshenziselwa ukukhonjwa okuphelele kwenani layo elibonisa.
Umhloli we-Microhardness ufaka umthwalo ekusebenzeni kokuhlolwa njengebushelelezi futhi umfaniswano ngangokunokwenzeka, ngaphandle komthelela kanye nokudlidliza. Ukuze uqinisekise ukunemba kwemiphumela yokuhlola, kuvame ukudingekile ukukala amahlandla ambalwa ezingxenyeni ezihlukene, bese uthola inani eliphakathi ukumela ubulukhuni besendlalelo sokuhlolwa kwe-permeabilility noma isigaba se-alloy. Ngesendlalelo sokungena ngaphakathi esisetshenziswa ekushiseni okuphezulu, ubulukhuni baso bungalinganiswa ngokusebenzisa i-high s izingalo lokushisa eliphakeme micronardness tester.
