Ko nga taputapu tito waea weld a Flux e anga mai ana
Ko te GEH-547Mo he hiko-a-ringa e rite ana ki te GB / T984 EDCr-A2-15 o te paerewa a-motu Hainamana, e whakamahia ana ki nga momo papaa me te whakarewa mata whakarewa.Ko te nuinga o te waa e whakamahia ana mo te papa o te mata o te hiri hiri he iti ake te pāmahana mahi i te 510 ℃.Te aratau mahi fehokotaki'anga o DC hononga whakamuri e taea te tango.Ko te konganuku mo te mata he 12Cr13(1Cr13) te rino chromium ahua-ferritic.Na roto i te mana o te kounga o te tuku rauemi mata, hangarau hanga matatau me te tino tirotiro i te kounga o te hua, ko tenei hiko hiko e tika ana mo te 510 ℃ i raro i te taiao mahi e whakaaetia ana i te maakete, he pai te painga o te urupare o te maakete.
Taupānga me te Paerewa
Ko te nama nama GEH-507Mo tenei papaa-a-ringa-a-ringa e whakamahia ana i roto i nga kakahu whakarewa me te kohu wai, te waikawa ngoikore, te cavitation me etahi atu waahanga, penei i te mata hiri (te taiao mahi i raro i te 550 ℃), te rakau, te penupenu whakaranu, te mata o te mata kaikawe kaikawe.Mena ka whakamahia me te D577 electrode, ka taea e ia te whiwhi i te aukati abrasion pai.Na he ngawari te tukanga o te papa, kaore he whakamahana i mua i te whakapiri, kaore he maimoatanga wera i muri i te whakapiri, ma te whakamahi i te hononga whakamuri DC.
Ngā āhuatanga
Ko te GEH-507Mo he momo iti konutai hauwai momo teitei chromium maitai hardfacing Unuhia, mahi pai, iti pōrutu, ngāwari tango para, ahua ataahua, ngāwari ki te kawe i roto i te tukatuka mīhini;Ko te paparanga paparanga he ahuatanga o te tiini hau, te pakeke o te reo-nui, te pai o te waiariki me te aukati waikura.Ko tenei momo hiko-a-ringa me aro ki te maha o nga mea i mua i te whakapiri, kia kore ai e puta he hapa koretake ki te mahi whakapiri.Ko te waahi tuatahi: me whakamaroke ki te 300-350 ℃ mo te 1 haora i mua i te whakapiri.Wāhanga tuarua: te makuku mata rauemi turanga, waikura stains, hinu ki te kia tino tangohia.Ko te tuatoru o nga waahi: kia tupato ki te huarahi o te arc me te arc, arc i muri i te ahi o muri o te ahi, remelting arc point, arc ki te whakakii i te rua arc.
