Isingeniso
Embonini yokucubungula insimbi,Ama-spot welders e-MFDC (Medium Frequency Direct Current).ziyimishini yokushisela ebalulekile, futhi ikhwalithi yazo yokushisela ithinta ngokuqondile ukuqina nokuphepha komkhiqizo. Nokho, ngezinye izikhathi phakathi nenqubo yokushisela, singase sihlangabezane nenkinga yamabhamuza avela ezindaweni zokushisela. Lokhu akuthinti nje ubuhle be-weld kodwa futhi kungaphazamisa amandla ayo. Lesi sihloko sigxile esihlokweni esithi "Kungani kukhona amabhamuza ezindaweni zokushiselaMFDC spot welders?", ihlola izimbangela zako, futhi inikeza izixazululo ezihambisanayo.
Ukuhlaziywa kwembangela
- Ukungcoliswa kobuso:Uma ingaphezulu lensimbi lingahlanzwa kahle ngaphambi kokushiselwa, ukungcola okusele okufana nowoyela, ukungcola, nama-oxide kungakhulula igesi ngaphansi kokushisa okuphezulu okushisela, kwakhe amabhamuza.
- Izinto eziguquguqukayo:Izinto eziguquguqukayo ezivela ezingxenyeni zokushisela noma indawo ezungezile, njengopende noma izinto zokuthambisa, zingahwamuka lapho kushisa. La magesi avaleleka echibini elincibilikisiwe, enze amagwebu.
- Ukumuncwa kwegesi:Izinto zensimbi zingamunca amagesi afana ne-hydrogen noma umoya-mpilo ngesikhathi sokushisela. Lapho izinga lokushisa lendawo likhuphuka, la magesi ayakhululwa, okuholela ekwakhekeni kwamabhamuza.
- Amapharamitha we-Welding angalungile:Izilungiselelo ezingalungile zamapharamitha afana namanje wokushisela, isikhathi, nokucindezela kungabangela ukushisa kwasendaweni noma ukushisisa okwanele kwezinto zokushisela, okuholela kumabhamuza.
- I-Metal Vapor:Emazingeni okushisa aphezulu, insimbi ingahwamuka kancane ibe umhwamuko. Uma lo mhwamuko uphola futhi ujiya, ungase futhi wenze amabhamuza.
- Izinto Zokushisela Ezingafani:Ukungaguquguquki kwamakhemikhali phakathi kwezinto ezihlukene kungaholela ekwakhekeni kwamabhamuza.
- Izinkinga Zegesi Yokuvikela:Izinkinga ezifana nokungahlanzeki okwanele kwegesi evikelayo noma ukuvuza kolayini begesi kungaholela ekuvikelekeni okubi kwegesi ngesikhathi sokushisela, okubangele amabhamuza kamuva.
Izixazululo
- Thuthukisa Ukuhlanza:Qinisekisa ukuthi ingaphezulu lensimbi lihlanzwa kahle ngaphambi kokushisela ukuze kukhishwe uwoyela, ukungcola, nama-oxides, unciphise imithombo yokukhipha igesi.
- Lawula Imvelo:Gwema ukushisela endaweni equkethe izinto eziguquguqukayo, noma wenze ukwehlisa nokuhlanza izingxenye ngaphambi kokushisela.
- Lungiselela Amapharamitha Welding:Setha amapharamitha afana ne-welding current, isikhathi, kanye nengcindezi ngokufanelekile ngokuya ngezinto zokushisela kanye nezidingo zenqubo ukuze ugweme ukushisisa ngokweqile kwendawo noma ukushisisa okunganele.
- Khetha Izinto Ezifanelekayo Zokushisela:Qinisekisa ukuhambisana kwezinto zokushisela ukuze ugweme ukusabela kwamakhemikhali okungazinzile.
- Hlola futhi Ugcine Isistimu Yegesi Evikelayo:Qinisekisa ukuhlanzeka kwegesi evikelayo (qinisekisa ukuthi ingaphezu kuka-99.7%); hlola njalo izintambo zegesi ukuthi azivuzi yini futhi uqinisekise ukuthi zihlanzekile; hlola ukuthi i-valve ye-solenoid elawula igesi evikelayo kusishiseli isebenza kahle yini.
- Hlanza Njalo I-Nozzle:I-Spatter inganamathela ku-nozzle ngesikhathi sokushisela, okuthinta ukuvikelwa kwegesi. Ngakho-ke, hlanza i-nozzle njalo, ngokuvamile kunconywa njalo ngemizuzu engu-20-30.
- Ama-Opharetha Esitimela:Qinisa ukuqeqeshwa kwabasebenza ukuze bathuthukise ukuqonda kwabo inqubo yokushisela nezinto zokusebenza, uqinisekise ukusebenza okujwayelekile kanye nezilungiselelo zepharamitha ezinengqondo.
Kafushane, izimbangela Bubbles at the weld amaphuzuMFDC spot weldersziyinkimbinkimbi futhi ziyahlukahluka. Kodwa-ke, ngokusebenzisa izinyathelo ezinjengokuhlanza okuthuthukisiwe, ukulawulwa kwemvelo, ukwenziwa ngcono kwepharamitha, ukukhetha izinto ezibonakalayo, ukunakekelwa kwesistimu yegesi evikelayo, ukuhlanzwa komlomo ovamile, nokuqeqeshwa komsebenzisi, singanciphisa ngempumelelo noma sigweme ukwakheka kwamabhamuza, ngaleyo ndlela sithuthukise ikhwalithi yokushisela.
