Isingeniso
Embonini yokucubungula insimbi, okuphakathiimishini ye-frequency spot weldingyimishini ekhethwayo yabakhiqizi abaningi ngenxa yokusebenza kahle kwabo okuphezulu nokusebenza okuzinzile kwe-welding. Kodwa-ke, ekusebenzeni okungokoqobo, ukwenzeka kwama-craters ngemva kokushisela akuthinti nje kuphela ukubukeka komkhiqizo kodwa kungase futhi kube usongo olukhulu emandleni esakhiwo kanye nempilo yesevisi yomkhiqizo. Lesi sihloko sigxile esihlokweni esithi "Indlela Yokuxazulula Inkinga Ye-Craters Ngemva KwesikhashanaI-Frequency Spot Welding?" ngokuhlola ngokujulile izimbangela zama-craters nokunikeza izixazululo eziningi ezingenzeka.
Izinkinga ze-Craters
- Imingcele Yokushisela Engafanele: Izilungiselelo ezingenangqondo zemingcele ezifana nesikhathi sokushisela kanye nesikhathi sokushisela kuholela ekugxilweni okukhulu kokushisa okushisela, okubangela ukuncipha kokungalingani kwensimbi encibilikisiwe ngesikhathi sokuqina kanye nokwenza ama-craters.
- Izimpawu Zento Ebalulekile: Umehluko wezakhiwo ezibonakalayo ezifana ne-thermal conductivity kanye nendawo encibilikayo yezinto zensimbi ezehlukene kwenza ezinye izinto zithandeke kakhulu kuma-craters ngesikhathi sokushisela.
- Isimo Sendawo Yokusebenzela: Ukuba khona kwamabala kawoyela, ama-oxide, noma okunye ukungcola endaweni yokusebenza, noma indawo engalingani, kuthinta ikhwalithi yokushisela futhi kwandisa ubungozi bokwakheka kwe-crater.
- I-Electrode Wear Nomumo: Ukuguga okunamandla kwama-electrode noma ukuma okungafanele kuholela ekusabalaliseni kwamanje okungalingani ngesikhathi sokushisela, okuholela ekushiseni ngokweqile kwendawo kanye nokwakheka kwe-crater.
Izixazululo
- Lungiselela Amapharamitha Welding: Lungisa kahle imingcele efana ne-welding yamanje kanye nesikhathi se-welding ngokusekelwe ohlotsheni nobukhulu bezinto zokushisela kanye nekhwalithi edingekayo yokushisela. Ngokuhlola okuphindaphindiwe, thola inhlanganisela efanele yamapharamitha ukuze ugweme ukugxiliswa kokushisa okweqile.
- Thuthukisa Isimo Sendawo Yokusebenzela: Hlanza kahle indawo yokusebenza ngaphambi kokushisela ukuze ususe amabala kawoyela, ama-oxide, nokunye ukungcola, uqinisekise indawo ebushelelezi nengenasici. Izindlela ezinjengokugaya noma i-sandblasting zingasetshenziswa ukuthuthukisa izinga eliphezulu.
- Khetha Ama-Electrode Afanelekile: Khetha izinto ezifanele zama-electrode kanye nokwakheka okusekelwe ezidingweni zokushisela. Hlola njalo ukuguga kwama-electrode futhi ushintshe ama-electrode aguge kakhulu ngesikhathi esifanele ukuze uqinisekise ukusatshalaliswa kwamanje okuzinzile.
- Sebenzisa Izinyathelo Zangaphambili-Zokucindezela Nokupholisa: Phambili-cindezela ucezu lokusebenza ngaphambi kokushisela ukuze unciphise ukuwohloka phakathi nenqubo yokushisela. Ngesikhathi esifanayo, thatha izinyathelo zokupholisa ezifanele, njengokwandisa ukugeleza kwamanzi okupholisa noma ukusebenzisa izinto zokupholisa, ukuze unciphise izinga lokushisa endaweni yokushisela futhi unciphise amathuba okwakheka kwe-crater.
- Okuthunyelwe-Ukucubungula Nokulungisa: Kuma-craters akhona, -izindlela zokucubungula iposi ezifana nokugaya noma ukugcwalisa zingasetshenziswa. Khetha indlela yokulungisa efanele ngokusekelwe kusayizi nokujula kwe-crater ukuze uqinisekise ukuthi indawo ekhandiwe ihlangabezana nezidingo zekhwalithi yokushisela.
- Ukuqeqeshwa Nokusekelwa Kwezobuchwepheshe: Qinisa ukuqeqeshwa komsebenzisi ukuze bathuthukise ukuqonda kwabo namandla abo ekulungiseni imingcele yokushisela, ukwelashwa kwendawo yokusebenza, ukukhetha ama-electrode, kanye nokushintshwa. Ukwengeza, hlinzeka ngosizo lobuchwepheshe oludingekayo ukubhekana nezinkinga ezihlukahlukene okuhlangatshezwane nazo ngesikhathi senqubo yokushisela.
Kafushane, ukuxazulula inkinga yama-craters ngemva kwe-mediumi-frequency spot weldingkudinga-indlela enezinhlangothi eziningi, okuhlanganisa ukwenza ngcono amapharamitha wokushisela, ukuthuthukisa izimo ezingaphezulu kwendawo yokusebenza, ukukhetha ama-electrode afanelekile, ukusebenzisa{1}}izinyathelo zokucindezela nokupholisa ngaphambili,{2}}zokucubungula nokulungisa, kanye nokuthuthukisa ukuqeqeshwa nokusekelwa kobuchwepheshe. Ngokusebenzisa lezi zinyathelo, ubungozi bokwakheka kwe-crater bungancishiswa ngempumelelo, kuthuthukiswe ikhwalithi yokushisela kanye nokuncintisana komkhiqizo.
