Amagoda e-Copper aziswa kakhulu ekuxhumekeni kukagesi nasekusetshenzisweni okushisayo ngenxa yokuguquguquka kwawo okukhethekile kanye nokusebenza kwawo. Nokho, abakhiqizi abaningi babhekana nenselelo ekhungathekisayo lapho besebenzisa-i-press welding eshisayo (Crimping/I-Resistance Welding): kungani ithusi elisendaweni yokushisela kanye nezindawo ezizungezile lishintsha lisuka ekubeni yinsimbi ekhanyayo libe "ithusi-elinsundu" elifiphele noma libe mnyama imbala? Lokhu akulimazi nje ubuhle bomkhiqizo; kungenza amakhasimende angabaze-ukuthembeka kwesikhathi eside kwawo wonke umhlangano.
i-copper braided strip cindezela isikwele
Lesi sihloko sisebenza njengomhlahlandlela wakho wobuchwepheshe ukuze uqonde izimbangela ze-copper braid discoloration ngemva kokucindezela okushisayo. Okubaluleke nakakhulu, sizodalula isixazululo esiqinisekisiwe, esiphrofeshinali: inhlanganisela ebalulekile yama-electrode e-tungsten kanye nesistimu yokupholisa{1}}yamanzi eqhubekayo. Okokugcina, sinikeza umhlahlandlela osebenzayo womthengi wokukusiza ukuthi ubone ukucushwa okubalulekile emshinini wokuhlanganisa i-copper braid omisa ukuguquguquka emthonjeni, uqinisekisa ukuthi ulayini wakho wokukhiqiza uletha ngokuqhubekayo imikhiqizo eshiselwe{3}}enhle, futhi esezingeni eliphezulu.
Kungani I-Copper Braids Ishintsha Umbala Ngemva Kokushisa-Cindezela Ukushisela?
Ukuze uxazulule inkinga, kufanele uqale uqonde umsuka wayo. Ukushintsha kombala okubonwa kuma-braids e-copper ngemva kokushisela akubangelwa into eyodwa, kodwa kuwumphumela ohlangene wokushintsha ngokomzimba namakhemikhali ngaphansi kwamazinga okushisa aphezulu.
Imbangela:-I-Oxidation Yezinga Lokushisa Ephezulu
Ngokombono wamakhemikhali, "umdali" obangela ukuguquguquka kombala -ukushisa okuphezulu kwe-oxidation. I-Copper iyinsimbi esebenza kancane. Ezingeni lokushisa lasekamelweni, ifilimu ye-oxide ezacile kakhulu, esobala yakha kancane kancane endaweni yayo, ivikela ingaphakathi ekugqwaleni okwengeziwe. Kodwa-ke, ngesikhathi sokushisela{4}}okushisayo, amazinga okushisa angakhuphuka ngokushesha afike kumakhulu noma izinkulungwane zamadigri Celsius. Ngaphansi kwalezi zimo ezimbi kakhulu, ithusi liphendula ngobudlova nomoya-mpilo osemoyeni, ngokushesha lenze ungqimba olubonakalayo lwe-oxide.
Lesi sendlalelo se-oxide ngokuvamile siyingxube ye-cuprous oxide (Cu₂O, okubomvu okumnyama) ne-copper oxide (CuO, emnyama). Uma izinga lokushisa liphakeme endaweni yokushisela futhi isikhathi eside sichayeka ekushiseni, kulapho ukusabela kwe-oxidation kuba okuphelele. Umbala uyajula usuka obomvu ngokumnyama uye onsundu ngokujulile, ekugcineni ube mnyama. Lokhu kuyimbangela eqondile "yokuguquka kombala" okubonayo.
Ukwakhiwa Kokushisa-Indawo Ethintekile (HAZ) kanye Nemiphumela Ye-Annealing
Ngalé kwendawo yokushisela eseduze, ukushisa kukhipha ngaphandle njengama-ripples echibini, kudala indawo yoshintsho eyaziwa ngokuthi i-Heat-Affected Zone (HAZ). Nakuba ithusi kulesi sifunda lingancibiliki, liba nomjikelezo wokushisisa nokupholisa okusheshayo{2}}okuyinqubo eyaziwa nge-metallurgy ngokuthi "i-annealing."
I-Annealing ishintsha ukwakheka kwekristalu encane yethusi, okubangela ukuthi okusanhlamvu kugwadule futhi kukhishwe izingcindezi zangaphakathi. Lolu shintsho lwesakhiwo luphinde luthinte izici zokubona kwendawo, okuholela ekulahlekelweni kokucwebezela nokwenza umbala ubonakale ufiphele kunethusi lokuqala. Ngakho-ke, ngisho nangaphandle kwe-oxidation eqinile, i-HAZ ebanzi ingenza yonke indawo eshiselwe ibukeke ingakhangi.
Imikhawulo yama-Electrode Endabuko
Imishini eminingi yokushisela yendabuko isebenzisa ama-electrode e-copper{0}based alloy, njenge-Chrome Zirconium Copper (CrZrCu). Nakuba lawa ma-electrode ane-conductivity enhle nezindleko eziphansi, anamaphutha emvelo lapho eshisela ithusi. Iphuzu lazo lokuncibilika (cishe. 1083℃) lisondele kakhulu kumluko wethusi ngokwawo. Ngaphansi komthelela-wokushisa okuphezulu okuphindaphindiwe, i-electrode ayigcini nje ngokukhipha i-oxidize futhi iguge ngokushesha kodwa futhi "inganamathela" kumluko wethusi oncibilikisiwe.
Okubaluleke nakakhulu, lawa ma-electrode anekhono elilinganiselwe lokulawula ukushisa ngokunembile. Lokhu kuvame ukuholela ekubalekeni okushisayo noma ezikhathini zokushisa ngokweqile endaweni yokushisela, "okwengeza uphethiloli emlilweni" ukuze kube ne-oxidation enamandla kanye nokwanda kwe-HAZ, okwenza ukuguquguquka kucishe kungenakugwenywa.
Ukuhlanganisa Okubalulekile Okuthuthukile Ne-Precise Temperature Control
Njengoba sazi ukuthi inkinga isukela "ekushiseni okwedlulele" kanye "nokushisa isikhathi eside," isixazululo kufanele sijikeleze amagama angukhiye amathathu: Ukunemba, Isivinini, kanye Nokupholisa. Isixazululo somkhakha esivuthwe kakhulu nesithembekile ukuhlanganisa izinto ezithuthukisiwe zama-electrode nobuchwepheshe bokupholisa{1}obusebenza kahle kakhulu.
Isixazululo Esiyisisekelo 1: Kungani Kufanele Usebenzise Ama-Tungsten Electrodes
Ukukhetha ithuluzi elifanele kuyingxenye yempi. Emkhakheni wokushisa okunembayo-okushisela ngokucindezela, ama-electrode e-Tungsten asephenduke into engenakushintshwa ngenxa yezakhiwo zawo ezingenakuqhathaniswa:
| Impahla | Inzuzo Ye-Welding |
| I-Ultra{{0}High Melting Point | I-Tungsten inendawo ephakeme kakhulu yokuncibilika kunoma iyiphi insimbi (3422 degree). Ihlala izinzile ngaphansi kokushisa kwe-welding, ivimbela ukugqoka kwe-electrode kanye nokungcoliswa kwe-weld. |
| Excellent Thermal Stability | Igxilisa okwamanje endaweni encane yokushisisa "-okusheshayo", iqedela ukushisela ngama-millisecond ngaphambi kokuthi kwenzeke i-oxidation ebalulekile. |
| Ukunamathela Okuncishisiwe | I-Tungsten inobudlelwane obuphansi kakhulu bethusi, obuvumela ukuthi ikhulule ngokuhlanzekile ekushiseleni. Lokhu kuqinisekisa indawo ebushelelezi, ehlanzekile ngaphandle "kokungcola okwesibili." |
Isixazululo 2: Amanzi Aqhubekayo-Ukupholisa{2}}Ukhiye Wokulawula Okunembile
Uma ama-electrode e-tungsten exazulula inkinga "yokushisa ngokushesha", khona-ke Amanzi Aqhubekayo-Isistimu Yokupholisa iphendula kahle ngokuthi "indlela yokupholisa ngokushesha."
- Ukususa Ukushisa Okusheshayo: Imishini{0}}esebenza kahle kakhulu yokugoqa ihlanganisa amanzi{1}}iziteshi zokupholisa ngokuqondile kumakhanda noma izibambi zama-electrode. Phakathi nesigaba sokupholisa somjikelezo wokushisela, amanzi ajikelezayo asebenza "njengepompo yokushisa" enamandla, esusa ngokushesha inani elikhulu lokushisa okusele ku-electrode kanye nelunga.
- Ukunciphisa i-HAZ: Lokhu kupholisa okuphoqelekile,{0}}okushesha kakhulu kuyisici esibalulekile ekumiseni ukushisa kugobhoze kuyo yonke i-copper braid. Igcina i-HAZ ibe buncane obuncane, ivamise ukuvalelwa ku-weld nugget ngokwayo. Umphumela uba ukushisela okukhanyayo, okuqinile okuzungezwe ithusi eligcina umbala walo wangempela kanye nokuguquguquka.
- Ukungaguquguquki Nokuphila Isikhathi Eside: Ukuze kukhiqizwe ngobuningi, amanzi{0}}okupholisa okuqhubekayo aqinisekisa ukuthi i-electrode iqala yonke i-weld ngezinga lokushisa lesisekelo elingaguquki. Lokhu kuqinisekisa ukuthi yonke i-weld ithola okokufaka kwamandla okufanayo, okuqinisekisa ikhwalithi ephezulu. Kuphinde kubambezele ngokuphawulekayo ukuguga komzimba kwama-electrode e-tungsten, kunwebe ubude bawo bempilo futhi kwehlise{3}}izindleko zesikhathi eside.
Ungawukhetha Kanjani Umshini Ovimbela Ukushintsha Kombala
Uma usulungele ukuthenga izinto zokusebenza, sebenzisa amaphuzu alandelayo njengemibandela yakho eyinhloko yokuhlola nokwenza{0}}izinqumo.

- Isilawuli Samandla:Umshini -wokuhlanganisa ama-tier crimping kufanele ube namandla okushisela athuthukile. Qinisekisa ukuthi isekela ukushaya kwenhliziyo okunembile, okukuvumela ukuthi uhlele izikhathi zokushisela (kuze kufike ku-millisecond) kanye namaleveli amanje ngobumbudumbudu obuhle. Leli zinga lokulawula liyisisekelo senqubo "ye-weld esheshayo, epholile ngokushesha".
Amandla Okucubungula Okuqinisekisa
- Cela Amasampula Abukhoma:"Ukubona ukukholwa." Ngaphambi kokwenza isinqumo sokugcina, letha amasampula akho e-copper braid futhi ugcizelele ukuthi umphakeli enze isivivinyo sokushisela bukhoma.
- Hlola Ikhwalithi Ye-Weld:Hlola eduze amasampula. Sebenzisa le mibuzo njengemibandela yokwamukela kwakho: Ingabe kukhona ukushintsha kombala ku-weld noma eduze kwe-weld? Ingabe i-weld nugget iqinile, ibushelelezi, futhi ayinazo izimbotshana? Ingabe i-braid ezungezile ihlala iguquguquka futhi igcina umbala wayo woqobo wethusi?
- Xhumana namapharamitha wenqubo:Xhumana ngokujulile nonjiniyela bezobuchwepheshe bomphakeli. Cela amapharamitha anconyiwe osayizi bakho abathile be-braid (cross-isigaba, ububanzi). Umphakeli osemnkantshubomvu kufanele ahlinzeke ngesizindalwazi esivuthiwe, esithembekile semingcele yenqubo, ebonisa ubunkimbinkimbi bobuchwepheshe babo.
Iseluleko Sochwepheshe esivela ku-HAIFEI
- Isifinyezo:Ohlwini lwakho lokuhlola ukuthengwa kwempahla, yenza "ukuthola ukuguquguquka{0}okushiselwa kwamahhala" kube yisidingo esiyinhloko sobuchwepheshe, hhayi nje isici "esihle-ukuba{2}}sokuba" nje.
- Isincomo:Gwema ugibe "lwentengo-kuphela". Phatha "ama-tungsten electrode" kanye "namanzi ahlanganisiwe{2}}asebenza kahle kakhulu{3}}okupholisa" njengezimfuneko{4}}ezingenakuxoxisana. Ukutshalwa kwezimali kokuqala ezintweni ezifanele kuzokhokha izikhathi eziningi ngekhwalithi yomkhiqizo, ukusebenza kahle kokukhiqiza, kanye nokwaneliseka kwamakhasimende.
- -Ukubuka Kwesikhathi eside:Ukukhetha umshini okhiqiza ngokuqhubekayo-amashisela ekhwalithi ephezulu, umbala{1}}onembile kusho ukuthi uletha umkhiqizo omuhle kakhulu nothembekile kumakhasimende akho.
