Amathiphu ayisithupha okukhetha ubucwebe begolide

Bayanda abantu abaqala ukuthenga ubucwebe begolide, kungakhathaliseki ukuthi bemindeni yabo, abadala, abangani, noma ukuzigqoka kuhle. Inencazelo enhle nokubukeka okuhloniphekile. Ngakho-ke ingabe uyazi ukuthi ungakhetha kanjani ubucwebe begolide? Inemithetho ecacile kulogo kanye nethegi emihlobiso yegolide. Ngokuvamile, kufanele kube negama lekhodi, igama lempahla, uphawu lokuqukethwe, njll. womkhiqizi. Ubucwebe begolide ngaphandle kwalolu lwazi kungumkhiqizo ongafanelekile! Ungathengi lokho okushiwo umdayisi. Lapho uthenga imihlobiso yegolide, into ebaluleke kakhulu okufanele uyikhathalele "umbala" wayo, okuwukuqukethwe kwegolide emihlobiso yegolide.1. Bheka uphawu lwamaphuzuUkuhlonza i-score okuqukethwe kwegolide kubucwebe begolide obuvezwa njengephesenti kanye nenkulungwane. Isibonelo, uma i-G990 noma i-Au990 imakwe, kusho ukuthi okuqukethwe kwegolide kulobu bucwebe begolide kungu-99%; uma i-G586 noma i-Au586 imakwe, kusho ukuthi okuqukethwe kwayo kwegolide kungu-58.6%. Okwangaphambili kunokuqukethwe kwegolide okuphezulu nombala ongcono, ngokuqinisekile kuyabiza kakhulu. Lapho ukhetha, vele ubheke ukuhlonza amaphuzu futhi uzokwazi okuqukethwe kwegolide.2. Bheka uphawu lombhaloNgaphezu kophawu lwamaphuzu, eminye imikhiqizo yegolide izoba nophawu lombhalo, olulula futhi olucace kakhudlwana. Kunamagama ama-2 kuphela - igolide elimsulwa (igolide elinegolide elingekho ngaphansi kwama-99.0%). Ngaphezu kwalokho, kukhona namamaki afana ne-Inlaid Metal, Izinkulungwane zegolide elihlanzekile, elibhekisela emihlobiso yegolide enegolide elingekho ngaphansi kuka-99.9% noma u-99.99%. Kodwa-ke, izwe lethu selikuhoxile kakade ukuqanjwa kwensimbi enamathiselwe kanye nezinkulungwane zegolide elihlanzekile, futhi lezi zimpawu ezimbili ngeke zisavela emihlobiso yegolide. . Igolide esandleni linomuzwa wokuwa futhi ithusi esandleni liyasinda kodwa ngaphandle nomuzwa wokuwa. Ukuhlanzeka kwegolide elihlanzekile nobucwebe begolide obuqinile kuphakeme kakhulu, kuzinzile kakhulu. Umsindo womgexo wangokwezifiso wobucwebe uwa noma ushayisana wodwa uzonyakaziswa futhi uzinze, unomsindo wokushaywa, futhi ngeke unyakaze lapho uwa; izinga eliphansi, ukuhlanzeka okuphansi ngisho nokufika kwegolide mbumbulu noma ukungqubuzana komunye nomunye, izokhipha umsindo wensimbi "we-dangdang", ngezinye izikhathi izoshaya umsindo, futhi izoshaya ngemva kokufika. Kodwa ungayiqhubi ngamandla. Qaphela i-deformation.Bheka umbala nokucwebezela. Ubucwebe begolide obunombala obomvu nophuzi bungcono kakhulu, kodwa futhi qaphela ukugcina umbala wokubukeka komkhiqizo, imibala emibi i-cyan emnyama. Eminye imihlobiso ifiphele kakhulu ngombala njengombala kapende ofuthwe ngaphandle.Qinisekisa ukuthi uwuthinta ngesandla ukuze ubone ukuthi uphawu luhle yini, uma kukhona ama-welds axegayo, uma kukhona ukuphuka, uma kubi, noma uma inkinobho kulula ukuwa, zonke lezi zidinga ukuhlola ngokucophelela. Ngasikhathi sinye, ubucwebe begolide obuhlanzekile obungokwezifiso bulula ukuwulimaza, futhi kufanele kubonakale ukuthi ukwakheka okuphelele kukhubazekile noma cha. Ukuthungwa kobuso bobucwebe begolide akunakunakwa. Kudingekile ukukhetha ubucwebe ngobucwebe obucacile, ukukhanya okuhle ngisho nokuthungwa. Ngesikhathi sokuthenga, kufanele futhi unake ukuthi imiphetho yobucwebe ibushelelezi yini, ubucwebe obuhle benziwe ngendlela exakile.Ubucwebe begolide bulula ukugoba, igolide lihlanzekile, lithambile. Ubucwebe begolide obuqinile buqinile obungu-2.5, obucishe bufane nozipho lomuntu, ngakho izinzipho zingasetshenziswa ukudweba amamaki amahle. Uma kuqhathaniswa nezinye izinsimbi, kunzima ukugoba (ifanele amagremu amancane emihlobiso yegolide esindayo, njengamagremu amakhulu ezinsimbi zegolide azikwazi ukugoqwa).igama langokwezifiso umgexo
