01.Incazelo emfushane
I-Spot welding iyindlela yokushisela ukumelana lapho izingxenye zokushisela zihlanganiswa zibe ama-lap joints futhi zicindezelwe phakathi kwama-electrode amabili, kusetshenziswa ukushisa okumelana nokuncibilikisa isisekelo sensimbi ukuze kwakheke amalunga e-solder.
I-Spot Welding isetshenziswa kakhulu kulezi zici ezilandelayo:
1. Ukugqagqana kwezingxenye zokunyathela zamapuleti amancane, njengamakhabethe ezimoto, amakhompathimenti, izikrini zesikali sezinhlanzi zokuvuna, njll.
2. Ipuleti elizacile nezakhiwo zensimbi ezinomumo kanye nezakhiwo zesikhumba, njengezindonga nosilingi oseceleni kwekalishi, amaphaneli enqola yama-trailer, amafaneli ahlanganisayo okuvuna, njll.
3. Izikrini, amafreyimu esikhala kanye nezinsimbi zensimbi eziphambanayo, njll.
02.Izici
Ngesikhathi sokushisela, i-weldment yenza ijoyinti eleqayo futhi icindezelwe phakathi kwama-electrode amabili. Izici zayo eziyinhloko zimi kanje:
1. Ngesikhathi sokushisela indawo, isikhathi sokushisa sendawo yokuxhuma sifushane kakhulu futhi isivinini sokushisela siyashesha.
2. I-Spot welding isebenzisa amandla kagesi kuphela futhi ayidingi izinto zokugcwalisa, i-flux, igesi, njll.
3. Izinga lokushisela indawo liqinisekiswa ngokuyinhloko ngumshini wokushisela indawo. Inokusebenza okulula, izinga eliphezulu lemishini kanye ne-automation, kanye nokukhiqiza okuphezulu.
4. Amandla okusebenza aphansi kanye nezimo ezinhle zokusebenza.
5. Njengoba i-welding iqedwa ngesikhathi esifushane futhi idinga umshini omkhulu wamanje nokucindezela, ukulawulwa kohlelo lwenqubo kuyinkimbinkimbi, umshini wokushisela unomthamo omkhulu kagesi, futhi intengo yemishini iphakeme kakhulu.
6. Kunzima ukwenza ukuhlolwa okungabhubhisi kwamalunga e-solder.

03.Inqubo yokusebenza
Ngaphambi kwe-welding, ingaphezulu le-workpiece kufanele lihlanzwe. Ukwelashwa okuvame ukusetshenziswa kokuhlanza i-picling, okungukuthi, kuqala kufakwe emanzini ashisayo e-sulfuric acid nge-concentration ye-10%, bese kugezwa emanzini ashisayo. Inqubo ye-welding ethize imi kanje:
(1) Yondla i-workpiece ehlangene phakathi kwama-electrode aphezulu naphansi omshini wokushisela bese uyibamba;
(2) Uma kusetshenziswa ugesi, izindawo zokuthintana zalezi zinto ezimbili zokusebenza ziyashisisa, zincibilike kancane, bese kwakheka i-nugget;
(3) Gcina ingcindezi ngemva kokucisha kwamandla, ukuze i-nugget encibilikisiwe iphole futhi iqine ngaphansi kwengcindezi yokwenza amalunga e-solder;
(4) Susa ukucindezela bese ukhipha ucezu lokusebenza.
04.Izici ezinomthelela
Izici eziyinhloko ezithonya ikhwalithi ye-welding zifaka isikhathi se-welding samanje namandla, ingcindezi ye-electrode kanye ne-shunt, njll.
1. I-Welding yamanje kanye nesikhathi sokusebenza kwamandla
Ngokusho kobukhulu be-welding current kanye nobude bamandla-ngesikhathi, ukushisela kwendawo kungahlukaniswa ngezinhlobo ezimbili: i-gauge eqinile kanye ne-soft gauge. Ukucaciswa okudlula umsinga omkhulu ngesikhathi esifushane kubizwa ngokuthi ukucaciswa okunzima. Inezinzuzo zokukhiqiza okuphezulu, impilo ende ye-electrode, kanye ne-deformation encane ye-weldment, futhi ifanele izinsimbi zokushisela ezine-conductivity enhle yokushisa. Igeji edlula amandla amancane esikhathini eside ibizwa ngokuthi i-soft gauge, enokukhiqiza okuphansi futhi ifanele izinsimbi zokushisela ezivame ukuqina.
2. Umfutho we-electrode
Ngesikhathi sokushisela, ukucindezela okwenziwa ekushiseleni nge-electrode kubizwa ngokuthi i-electrode pressure. Ukucindezela kwe-electrode kufanele kukhethwe ngokufanele. Uma ukucindezela kuphezulu, imigodi yokuncipha kanye nokuncipha okungenzeka lapho i-nugget iqina ingaqedwa. Kodwa-ke, ukumelana nokuqina kwamanje kwe-electrode kuyancishiswa, okuholela ekushiseni okunganele kwe-weldment kanye nokunciphisa ububanzi be-nugget. Amandla okuhlangana kwe-solder ayancipha. Ubukhulu bengcindezi ye-electrode bungakhethwa ngokusekelwe kulezi zici ezilandelayo:
(1) Izinto zokushisela. Ayanda amandla okushisa aphezulu wento. Okukhulu umfutho we-electrode odingekayo. Ngakho-ke, lapho kushiselwa insimbi engagqwali nensimbi engangeni ekushiseni, kufanele kusetshenziswe ingcindezi ephakeme ye-electrode kunalapho kushiselwa insimbi enekhabhoni ephansi.
(2) Imingcele yokushisela. Ukuqina kokucaciswa kokushisela, kuyanda ukucindezela kwe-electrode.
3. Ukuphambukisa
Ngesikhathi sokushisela indawo, i-current egeleza ngaphandle kwesekethe enkulu yokushisela ibizwa ngokuthi i-shunt. I-shunt inciphisa ukugeleza kwamanje endaweni ye-welding, okuholela ekushiseni okunganele, okubangela ukwehla okuphawulekayo kwamandla we-solder joint futhi kuthinte ikhwalithi yokushisela. Izinto ezithinta izinga lokuphambukisa zifaka phakathi izici ezilandelayo:
(1) Ukujiya kokushisela kanye nesikhala sephoyinti lokushisela. Njengoba ibanga phakathi kwamalungu e-solder likhula, ukumelana ne-shunt kuyanda futhi izinga lokushunqisa liyehla. Uma kusetshenziswa isikhala esivamile sephoyinti esingama-30 kuya ku-50 mm, i-shunt yamanje ibalelwa ku-25% kuya ku-40% yenani eliphelele lamanje, futhi njengoba ubukhulu be-weldment buncipha, izinga lokushunqisa nalo liyehla.
(2) Isimo sokushisela. Uma kukhona ama-oxides noma ukungcola ebusweni be-weldment, ukumelana nokuxhumana phakathi kwama-weldments amabili kuyanda, futhi ukudlula kwamanje endaweni ye-welding kunciphisa, okungukuthi, izinga lokukhuphuka liyakhula. I-workpiece ingaba pickled, sandblasted noma polished.
05.Izinyathelo zokuphepha
(1) Ukushintshwa kwezinyawo zomshini wokushisela kufanele kube nesembozo esiqinile sokuvikela ukuvimbela ukusebenza ngengozi.
(2) Indawo okusetshenzwa kuyo kufanele ifakwe izimpintsha ukuze kunqandwe ukundiza kwezinhlansi.
(3) Abashiselayo kufanele bafake izibuko zokuzivikela eziyisicaba lapho beshisela.
(4) Indawo lapho umshini wokushisela umshini wokushisela kufanele igcinwe yomile, futhi phansi kufanele kugandaywe ngamapuleti avimbela ukushibilika.
(5) Ngemva kokuba umsebenzi wokushisela usuqediwe, ugesi kufanele unqanyulwe, futhi inkinobho yamanzi okupholisa kufanele inwetshwe imizuzwana eyi-10 ngaphambi kokuvala. Uma izinga lokushisa liphansi, amanzi anqwabelene emgudwini wamanzi kufanele asuswe ukuze avimbele ukubanda.
