Maerekitirodhi eNickel Baseinomiririra chikamu chakakosha chezvinoshandiswa pakuwedera chakagadzirirwa kubatanidza ma alloys anoshanda zvakanyanya nesimbi dzakasiyana. Iyo Ni327-3 (AWS A5.11 ENiCrMo-3) ine hydrogen sodium coating yakaderera uye inoshanda paDCEP (Direct Current Electrode Positive) polarity. Iyi electrode inogadzira simbi yakachengetwa ine plasticity yakanyanya, kuomarara, uye kuramba kutsemuka, ichichengetedza simba rakawanda uye kuramba ngura kwepamusoro pese patembiricha yemumba neyakakwira. Kuumbwa kwayo kwemakemikari kunovimbisa kushanda kwakavimbika munzvimbo dzinoda maerekitironi akajairwa.
Hunhu hwesimbi hwemaerekitirodhi aya hunoita kuti anyatsokodzera kusanganisa nickel-chromium-molybdenum alloys. Simbi yakachengetwa inowanzo kuve ne 55% nickel, 20-23% chromium, uye 8-10% molybdenum, zvichigadzira microstructure yakasimba inodzivirira mhando dzakasiyana dzengura dzinosanganisira kupwanya makomba uye stress corrosion. Hunhu hwemakanika hunosanganisira simba rekudhonza rinodarika 760 MPa uye mwero wekureba uri pamusoro pe27%, zvichiita kuti pave nesimba uye kuchinjika kwejoini rakasungirirwa.
Zvikumbiro zvemaindasitiri zveMaerekitirodhi eNickel BaseAnosanganisira zvikamu zvakasiyana-siyana zvinosanganisira kugadzirisa makemikari, kugadzira magetsi, uye uinjiniya wegungwa. Anoshandiswa zvakanyanya mukusunga zvinhu zvakakosha zvakaita sema reactors, heat exchangers, uye mapaipi anoshanda pasi pekupisa kwakanyanya uye mamiriro ekuora. Ma electrodes anoratidza kushanda kwakakosha mukubatanidza simbi dzakasiyana uye pakusunga pamusoro pesimbi yekabhoni, zvichipa zvese zvakanakira zvehupfumi uye zvehunyanzvi mukugadzira nekugadzirisa michina.
Mabatirwo nemazvo uye nzira dzekusonwa kwakakodzera zvakakosha kuti maerekitirodhi aya ashande zvakanaka. Kuomesa usati watanga pa300°C kwemaminitsi makumi matanhatu inokurudzirwa kubvisa hunyoro uye kudzivirira matambudziko ane chekuita nehydrogen. Vashandi vanofanira kuchengetedza kureba kwearc pfupi uye kupisa kuri pakati nepakati kuchengetedza hunhu hwesimbi yakachengetwa. Tembiricha dzepakati pemasendimita dzinofanira kudzorwa pasi pe150°C, uye kuchenesa kwakanyatsonaka pakati pemapasi kwakakosha kuti pave nechokwadi chekuti ma welds haana zvikanganiso uye anodzivirira ngura zvakanyanya.
Maerekitirodhi eNickel Baseinopa mhinduro dzakakosha pakushandisa kwakaoma kwewelding mumaindasitiri akasiyana-siyana. Iyo Ni327-3 variant, inosangana neAWS ENiCrMo-3 specifications, inopa mashandiro akavimbika kuburikidza nekusanganiswa kwayo kwakaringana kwehunhu hwemakanika uye kuramba ngura. Aya maelectrode anoramba achishanda sezvikamu zvakakosha mukuchengetedza nekuvaka michina yeindasitiri inoshanda mumamiriro ezvinhu akaomarara ezvakatipoteredza.
