Emkhakheni wokulungiswa kwezimboni kanye nokulungiswa kwemishini,Induku Yokushisela Engaphezuluimele ukusetshenziswa okubalulekile kokwandisa impilo yenkonzo yezingxenye zemishini. Ngokungafani nezinduku zokushisela ezijwayelekile ezenzelwe ukuhlanganisa izinto, lolu hlobo lwe-electrode lwenzelwe ngqo ukufaka ungqimba lwe-alloy engagugi noma engagqwali ebusweni bensimbi eyisisekelo. Le nqubo, eyaziwa ngokuthi i-surfacing noma i-hardfacing, ibalulekile ekwakheni kabusha izingxenye ezigugile nokuvikela izingxenye ezintsha ekuhlulekeni kwangaphambi kwesikhathi.
I-D256 (B-80) iyisibonelo esihle se-Surfacing Welding Rod ekhethekile. Iyi-electrode eyisisekelo eyenzelwe ukufaka insimbi ye-austenitic manganese steel weld. Le alloy ethile yaziwa ngenhlanganisela yayo eyingqayizivele yokuqina okuphezulu kanye nekhono elimangalisayo lokuqinisa umsebenzi. Esimweni sayo sokuqala, insimbi efakiwe ithambile futhi ithambile, kodwa iqina ngokushesha lapho kubanda, okwenzeka ngaphansi kokushaywa noma ingcindezi, okwenza imelane kakhulu nokuguguleka okuqhubekayo.
Isicelo esiyinhloko salokhuInduku Yokushisela Engaphezuluisesimweni sokuvuselelwa nokuvikelwa kwezingxenye ezithinteke kakhulu ezihambisana namazinga aphakathi okuhuzuka. Ifaneleka kahle kakhulu ukushisela ezingxenyeni ezenziwe ngensimbi efanayo ye-austenitic manganese, into evame ukusetshenziswa ezimbonini ezicindezela kakhulu. Izingxenye ezijwayelekile ezilungiswa ngale nduku zifaka phakathi izindawo zokuwela isitimela, imihlathi yokuqhekeza, namazinyo efosholo ezimayini nasemishinini yokwakha.
Ukusetshenziswa kahle kwale Ndodo Yokushisela Engaphezulu kudinga ukunamathela ezinqubweni ezithile zokushisela ukuze kutholakale imiphumela emihle kakhulu. Ngenxa yokumbozwa kwayo okuyisisekelo, ngokuvamile isebenza emthonjeni wamandla we-Direct Current (DC) one-electrode exhunywe ku-positive pole (DCEP). Ukushisa insimbi eyisisekelo ngokuvamile akukhuthazwa ngezinsimbi ze-manganese, futhi ukulawula izinga lokushisa le-interpass kubalulekile ukuvimbela ukufakwa kokushisa okweqile, okungalimaza ukuqina kwensimbi efakiwe kanye nezinto eziyisisekelo.
Ukusetshenziswa okunesu kwe-specializedInduku Yokushisela Engaphezulunjenge-D256 (B-80) kuwumkhuba oyisisekelo ekuphathweni kwempahla yezimboni. Ngokukhetha i-electrode efanele yohlobo oluthile lokuguguleka—kulokhu, umthelela omkhulu—Amaqembu okulungisa angakha kabusha ngempumelelo izingxenye ezibalulekile, anciphise isikhathi sokungasebenzi, futhi anciphise izindleko zokusebenza zesikhathi eside. Le Surfacing Welding Rod inikeza ikhambi elithembekile nelisebenzayo lokuthuthukisa ukuqina kwemishini esebenza ngaphansi kwezimo ezidinga kakhulu.
