Kwicandelo lokugcinwa kwemizi-mveliso kunye nokulungiswa kwezixhobo,Intonga yokuWelda ephezu komhlabaimele into esetyenziswa kakhulu ekwandiseni ubomi benkonzo yezixhobo zoomatshini. Ngokungafaniyo neentonga zokuwelda ezisemgangathweni ezenzelwe ukudibanisa izinto, olu hlobo lwe-electrode lwenzelwe ngokukodwa ukufaka umaleko we-alloy engagugiyo okanye engagugiyo kumphezulu wesinyithi osisiseko. Le nkqubo, eyaziwa ngokuba yi-surfacing okanye i-hardfacing, ibalulekile ekwakheni kwakhona iindawo ezigugileyo kunye nokukhusela izixhobo ezintsha ekusileleni kwangethuba.
I-D256 (B-80) ngumzekelo obalaseleyo wentonga yokuwelda ekhethekileyo. Yi-electrode esisiseko eyenzelwe ukufaka isinyithi se-austenitic manganese steel weld. Le alloy ikhethekileyo yaziwa ngokudityaniswa kwayo okukhethekileyo kokuqina okuphezulu kunye nokukwazi kwayo ukuqinisa umsebenzi ngendlela engaqhelekanga. Kwimeko yayo yokuqala, isinyithi esifakwe kuyo sithambile kwaye sithambile, kodwa siqina ngokukhawuleza xa sitshintsha ukubanda, okwenzeka phantsi kwempembelelo okanye uxinzelelo, nto leyo eyenza ukuba singabi nakumelana nokuguguleka okungakumbi.
Isicelo esiphambili sale ntoIntonga yokuWelda ephezu komhlabaikwimeko yokulungiswa nokukhuselwa kwezinto ezichaphazeleka kakhulu kunye namanqanaba aphakathi okukrazula. Ifanelekile kakhulu ukuwelda kwiindawo ezenziwe ngentsimbi ye-austenitic manganese efanayo, into esetyenziswa kakhulu kumashishini anoxinzelelo olukhulu. Izinto eziqhelekileyo ezilungiswa ngale ntonga ziquka iindlela zokunqumla umzila kaloliwe, imihlathi yokuqhekeza, kunye namazinyo efosholo kwizixhobo zemigodi nezokwakha.
Ukusetyenziswa ngokufanelekileyo kwale Surfacing Welding Rod kufuna ukuthotyelwa kwiinkqubo ezithile zokuwelda ukuze kufumaneke iziphumo ezilungileyo. Ngenxa yokwambatha kwayo okusisiseko, isebenza kumthombo wamandla weDirect Current (DC) kunye ne-electrode eqhagamshelwe kwi-positive pole (DCEP). Ukufudumeza isinyithi esisisiseko akukhuthazwa ngokubanzi kwiintsimbi ze-manganese, kwaye ukulawula ubushushu be-interpass kubalulekile ukuthintela ukufakelwa kobushushu obugqithisileyo, okunokubeka emngciphekweni ukuqina kwesinyithi esigciniweyo kunye nezinto ezisisiseko.
Ukusetyenziswa ngobuchule kwesixhobo esikhethekileyoIntonga yokuWelda ephezu komhlabanjenge-D256 (B-80) yindlela esisiseko yolawulo lweeasethi zoshishino. Ngokukhetha i-electrode efanelekileyo yohlobo oluthile lokuguguleka—kule meko, impembelelo enzima—Amaqela okulungisa anokwakha kwakhona ngempumelelo izinto ezibalulekileyo, anciphise ixesha lokungasebenzi, kwaye anciphise iindleko zokusebenza zexesha elide. Le Surfacing Welding Rod ibonelela ngesisombululo esithembekileyo nesisebenzayo sokuphucula ukuqina koomatshini abasebenza phantsi kweemeko ezinzima kakhulu.
