Emkhiqizweni wezimboni,{0}}imvamisa emaphakathiimishini yokushisela amabalazibaluleke kakhulu ngokusebenza kahle kwazo nokonga amandla. Kodwa-ke, ukugqoka ama-electrode okusheshayo kuyinselelo evamile ethinta ngokuqondile ikhwalithi ye-weld, ukukhiqiza, nezindleko zokusebenza. Lesi sihloko sinikeza ukuhlaziywa okuhlelekile kwezimbangela zezimpande zokugqoka ama-electrode futhi inikeza izixazululo ezisebenzayo zokwandisa impilo yemishini.
Izilungiselelo Zamanje Nezingcindezi Ezingalungile
Ibhalansi phakathi kwe-welding current kanye ne-electrode force iyisici esiyinhloko esithonya ukuguga. Izilungiselelo ezingalungile zingehlisa ngokushesha ama-electrode.
Okwamanje Ngokweqile:Ubuningi bamanje budala ukushisa okuphazima kweso ethiphu le-electrode, okuholela ekuthambeni, ekuguquguqukeni, kanye "namakhowe."
Ingcindezi Enganele:Amandla aphansi abangela ukuthintana okungalungile, okwandisa ukumelana nogesi kanye nokugxilisa ukushisa endaweni ye-electrode esikhundleni sezinto zokusebenza, okubangela ukugoba nokunamathela.
Izixazululo:
Amapharamitha anembe:Setha okwamanje ngokusekelwe ohlotsheni lwempahla nogqinsi (isb, 8-12 kA/mm² ngensimbi epholile; ephakeme nge-aluminium).
Lungiselela Amandla:Gcina ukucindezela kwe-electrode ngaphakathi kwebanga elinconyiwe (isb, 0.2-0.4 MPa) ukuze uqinisekise ukwakheka okungaguquki kwe-nugget futhi unciphise isipatha.
Ukukhethwa Kwenqubo:Sebenzisa uhlelo lokushisela "oluqinile" (oluphezulu lwamanje, isikhathi esifushane) noma "elithambile" (eliphansi lamanje, isikhathi eside) ukuphatha umthwalo oshisayo kuma-electrode.
I-Electrode Material Engafanele
Ukukhetha into engalungile ye-electrode yohlelo lokusebenza kuyimbangela ehamba phambili yokuguga ngaphambi kwesikhathi.
I-Chromium Zirconium Copper (CrZr):Inhloso evamile{{0}inketho ene-conductivity kanye nobulukhuni bekhabhoni nezinsimbi ezingagqwali, kodwa igqoka ngokushesha-ezinamandla noma izinto ezibambayo.
I-Aluminium Oxide Copper (i-Alumina Cu):Ukumelana nokugqokwa okuhle kakhulu (okuphindwe ka-5x kune-CrZr), ilungele insimbi ne-aluminium ethambekele ekunamatheleni.
I-Tungsten Copper (WCu) / Molybdenum:Ukuqina-kwezinga lokushisa eliphezulu kubenza bafanelekele izinto ezisebenza kakhulu njengethusi nethusi, nakuba zibiza kakhulu.
Izixazululo:
Fanisa Impahla nesicelo:Sebenzisa i-Alumina Cu ngensimbi enamapulangwe; khetha i-WCu yama-alloys ethusi.
Imiklamo Ehlanganisiwe:Kuzinhlelo zokusebenza ezinzima, sebenzisa ama-electrode okufaka (isb, ithiphu ye-tungsten eshumekwe emzimbeni we-CrZr) ukuhlanganisa ukuguquguquka nokungagugi.
Ukupholisa okuphumelelayo kubalulekile. Uhlelo oluhlulekayo luyimbangela efihliwe yokugqoka okungavamile kwe-electrode.
Ukugeleza Kwamanzi Okubi/Izinga lokushisa:Ukugeleza okunganele noma izinga lokushisa eliphezulu lamanzi kuvimbela ukushisa ukuthi kungathwalwa, okwenza i-electrode ishise kakhulu futhi ithambe.
Imigqa Evaliwe:Isikali noma imfucumfucu eziteshini zokupholisa idala izindawo ezishisayo, okuholela ekuwohlokeni kwendawo.
Izixazululo:
Ukunakekela Okuvamile:Sebenzisa uhlu lokuhlola lwesistimu yokupholisa. Gada izinga lokugeleza nezinga lokushisa. Sebenzisa amanzi enziwe i-deionized noma isipholile esikhethekile ukuvimbela ukwakheka kwesikali.
Lungiselela Idizayini:Qinisekisa ukuthi iziteshi zokupholisa zangaphakathi zicacile. Khetha ama-electrode anamabhore amakhulu nama-overhang amafushane ukuze ukwandise ukuqeda ukushisa.
Isimo Esingesihle Sendawo Yokusebenzela
Isimo esiphezulu se-workpiece sithinta ngqo lapho kukhiqizwa khona ukushisa.
Ukungcola:Izendlalelo zikawoyela, ukungcola, ne-oxide zandisa ukumelana nendawo, okubangela ukushisa kugxile kusixhumi esibonakalayo se-electrode-okuholela ekushiseni ngokweqile nasekungcoleni.
Ukunamathela kwe-Splash:I-spatter yensimbi encibilikisiwe inganamathela ebusweni be-electrode, iguqule ukwakheka kwayo futhi isheshise ukugqokwa kokushisela okulandelayo.
Izixazululo:
Ngaphambi-ukuhlanza:Sungula inqubo{0}}yokuhlanza i-weld usebenzisa ama-degreaser noma izihlanzi ze-ultrasonic ukuze ususe ukungcola. Ukwelashwa kusengaphambili (isb, ukukha) kubalulekile ezintweni ezifana nensimbi.
Ukugcinwa{0}kwe-weld:Hlanza njalo amathiphu e-electrode ngefayela elizinikele noma isigqoko ukuze ususe ukunqwabelana nokugcina indawo yokuxhumana ehlanzekile, eyisicaba.
Isiphetho
I-Electrode igqoka-imvamisa emaphakathiumshini wokushisela indawoiyinkinga-enezici eziningi, kodwa ingaphathwa ngempumelelo. Ngokulungiselela amapharamitha wenqubo, ukukhetha izinto ezifanele ze-electrode, ukugcina uhlelo lokupholisa, nokuqinisekisa iziqephu zokusebenza ezihlanzekile, unganweba kakhulu impilo ye-electrode, uthuthukise ukungaguquguquki kwe-weld, futhi unciphise izindleko zizonke.
