I-electrode ilucingo olugqunyiweyo lwentsimbi kwaye kufuneka yenziwe ngokubanzi kwizinto ezifanayo kwiipropathi kunye nokwakheka kwintsimbi edityanisiweyo, kwaye kukho izinto ezininzi eziya ekukhetheni i-electrode efanelekileyo kwiprojekthi yakho ethile.
Ngelixa i-arc yentsimbi ekhuselweyo (i-SMAW) okanye i-electrode "yentonga" isetyenziswa kwaye ibe yinxalenye ye-weld, ezinye i-electrodes (ezifana nezo zisetyenziselwa i-TIG welding) azinakutyiwa, oku kuthetha ukuba azinyibiliki kwaye zibe yinxalenye ye-weld. umthungo. Ukwahlula komthungo, kwezi meko, ukusetyenziswa kwe-electrode kuyadingeka.
Thina e-Eng-weld siyazi ukuba ukukhetha i-electrode efanelekileyo kubalulekile kumandla we-weld, umgangatho we-weld, ukunciphisa i-spatter kunye nokucoca.
Ii-electrode ze-cellulose zi-electrode zokuwelda ezigqunywe ngesingxobo esinezinto eziphilayo. Ngokuqhelekileyo malunga ne-30% ngobunzima bengubo yi-cellulose, kodwa kwezinye iindawo zehlabathi i-cellulose kunye nomgubo weplanga unokongezwa kwi-coating ukunciphisa umxholo we-cellulose ococekileyo.
Iintlobo ezahlukeneyo ze-organic compounds kwi-electrodes ziya kubola kwi-arc ukwenza i-carbon dioxide, i-carbon monoxide kunye ne-hydrogen, yonke into eyandisa i-voltage ngaphakathi kwe-arc, okubangelwa i-arc eqinile kwaye inzima. Ngaloo ndlela, i-electrodes ye-cellulose inokungena ukuya kwi-70% enzulu kune-electrodes ehambelanayo kunye nokulinganisa kwangoku.
Ngokuqhelekileyo yenziwe ngengubo encinci okanye ephakathi, nangona oku kuvelisa i-slag enokususwa emva kokuba inkqubo ye-welding igqityiwe, oku kunokubangela ukulahlekelwa okukhulu kwe-spatter. Nangona kunjalo, isakhono se-welding esithe nkqo kunye nokukwazi ukungena kule electrode kuhle kakhulu ngenxa yokuzaliswa kwesithuba kwi-coating.
I-electrode ye-hydrogen ephantsi ngokuyimfuneko i-gas shielded arc welding (SMAW) esetyenziswayo kunye nomxholo wamanzi ongaphantsi kwe-0.6% xa kuthelekiswa nomthamo wamanzi we-4-6% we-cellulosic electrode.
Ngokuqhelekileyo, i-electrode ye-hydrogen ephantsi njenge-E7018 i-electrode ye-rod inika abasebenzisi i-spatter ephantsi kunye ne-arc egudileyo, ezinzileyo kunye neyokuthula. Ezi zakhiwo zenza ezi electrode zibe lukhetho oluhle kakhulu kubo bobabini abanamava kunye nabaqalayo. Iipropati zala ma-electrodes ensimbi yokuzalisa zibonelela nge-welder ngokulawula kakuhle kwe-arc kunye nokunciphisa imfuno yokucoca emva kwe-weld.
Ngokungafaniyo nezinye i-electrodes ezifana ne-E6010 okanye i-E6011, i-electrode ephantsi ye-hydrogen ibonelela nge-deposition ephezulu kunye namazinga okungena, okuvumela i-welder ukuba yongeze isinyithi kwi-joint nanini na, ukuphucula amandla e-weld kunye nokuphepha iziphene ze-welding ezifana nokungabikho kokungena.
Ngokubanzi, ii-electrode zentsimbi ezithambileyo zibonelela nge-arc ezolileyo nezizinzileyo enokungena okuphantsi, zizenze zilungele ukuvala umsantsa obanzi kunye nokusetyenziswa kwamaphepha amancinci. Nangona kunjalo, kukho iindidi ezahlukeneyo zee-electrode zentsimbi ezithambileyo, nganye ineempawu ezahlukileyo kwaye ke ifaneleka ngcono kwizicelo ezahlukeneyo.
Ngokomzekelo, i-grade 6013 yinjongo eqhelekileyo ye-electrode yensimbi ethambileyo enika ukungena okunzulu ngelixa igcina i-arc egudileyo kwaye izinzile. I-arc kulula ukuyihlaziya, i-welding seam ihle, i-spatter incinci, i-slag ilula ukuyilawula, ifanelekile kwi-vertical down welding.
I-7018 arc electrode, ngakolunye uhlangothi, i-electrode yensimbi epholileyo eyenzelwe ukuwelda i-carbon carbon steel materials. Le electrode isoloko isetyenziselwa ukuwelda kwesakhiwo ngenxa yokumelana nokuqhekeka kwe-weld. Kodwa oku kudala i-slag eninzi, engafanelekanga kwi-welding ephantsi.
I-electrode yokugqibela yentsimbi ethambileyo esiza kuyibona yi-6011. Le electrode yokungena enzulu eguquguqukayo ibonelela nge-arc egudileyo kwaye izinzile xa udibanisa intsimbi epholileyo kunye nezinye iintsimbi ezisezantsi. Ukugquma kwayo kudala i-arc enamandla yokungena okunzulu, kwaye i-slag layer incinci kwaye kulula ukuyisusa.
Njengezinye i-electrode esizibonile ngasentla, i-electrode yentsimbi engenastainless ivela kwiindidi ezahlukahlukeneyo, nganye yazo yahluke kancinane kuneyangaphambili.
Apha sijonga amabakala ama-3 ahlukeneyo e-electrode yensimbi engenasici, i-308, i-309 kunye ne-316, kunye nexesha lokuyisebenzisa.
Ukuba usebenzisa amabakala 301, 302, 304, 305 kunye ne-alloys yokuphosa i-CF-3 kunye ne-CF8, ngoko sincoma ukuba usebenzise i-308L, kuquka i-ER308LSi electrode. Ezi electrode zensimbi ezingenasici zifanelekile kwiintsimbi ze-austenitic stainless, kodwa kwizicelo ezifana nokuveliswa kwamandla, sincoma i-electrode ye-308H njengoko le electrode ephezulu yekhabhoni inika ukuxhathisa okungcono kwe-creep kumaqondo obushushu aphezulu.
Xa udibanisa intsimbi epholileyo okanye i-alloys yensimbi epholileyo kwintsimbi engenasici, sebenzisa i-309L, kuquka i-ER309LSi. Kukwasebenza okufanayo ekujoyineni iintsimbi ezahlukeneyo ezingenasici ezifana ne-409 okanye i-304L yensimbi engenasici. Ukongeza koku, kufuneka zisetyenziselwe ukubophelela iintsimbi ezisisiseko ezingama-309.
Xa usebenzisa isiseko sesinyithi se-316L kunye ne-316 kunye ne-cast elinganayo CF-8m kunye ne-CF-3M, kuphela i-316L kufuneka isetyenziswe njengesinyithi sokuzalisa, kuquka i-ER317LSi.
Ezinye izicelo ze-308L zinokuthatha indawo ye-309L njengentsimbi yokuzalisa njengoko ayifuni i-molybdenum ngokungafaniyo ne-316 okanye i-316L izicelo ezifuna i-molybdenum ngoko awukwazi indawo ye-309 nge-316.
Njengoko sibonile ngasentla, kukho iintlobo ngeentlobo zee-electrode ezikhoyo. Ngamnye kubo uneepropati ezahlukileyo kwaye ke ngoko zahluke kancinane kunye neempawu ezizodwa. Xa uqhuba nawuphi na umsebenzi wokulungisa kunye nokugcinwa, kufuneka kuthathelwe ingqalelo ukuze kuqinisekiswe ukuba i-electrode esetyenzisiweyo ineempawu ezifunekayo.
Okokuqala, qaphela ukuba luhlobo luni lwesinyithi oza kululungisa okanye ulusebenzise. Emva koko kufuneka wenze isigqibo sokuba ufuna i-electrode yenjongo jikelele okanye i-electrode eneempawu ezikhethekileyo. Nje ukuba unayo yonke le ngcaciso ungaqala ukuthengisa, ukuba awukwenzi kwaye usebenzise i-electrode engalunganga i-solder yakho iya kusilela okanye unokutshisa nje ngentsimbi osebenza nayo.
