Ukulayisha kuqala, okwaziwa nangokuthi ukucindezela kwangaphambili noma ukuminyanisa ngaphambili, kuyisinyathelo esibalulekile enqubweni yokushisela indawo yokushisela imvamisa emaphakathi.Lesi sihloko sihlola ukubaluleka kokulayisha kuqala kanye nomthelela wako kukhwalithi ye-weld nokusebenza.
Ukufinyelela Ukuqondanisa Okufanelekile Kwe-Electrode:
Enye yezinjongo eziyinhloko zokulayisha kuqala ukuqinisekisa ukuqondanisa kahle kwama-electrode ngaphambi kokuba inqubo yokushisela iqale.Ngokusebenzisa amandla okulayisha ngaphambilini alawulwayo, ama-electrode ahlanganiswa nezinto zokusebenza, asungula isixhumi esibonakalayo esizinzile nesiguquguqukayo se-electrode-to-workpiece.Lokhu kuqondanisa kubalulekile ekugcineni ukugeleza kwamanje okungaguquki kanye nokusabalalisa ukushisa ngesikhathi sokushisela, okuholela ekushiseni okuthembekile nokufana.
Ukuthuthukisa I-Electrical Conductivity:
Ukulayisha kuqala kusiza ukuthuthukisa ukuguquguquka kukagesi phakathi kwama-electrode nezinto zokusebenza.Ngokufaka ingcindezi, noma yikuphi ukungcola okungaphezulu noma ama-oxide angase avimbe ukuthintana kukagesi ayasuswa noma aphuke, okuvumela ukugeleza okungcono kwamanje.Ukuhamba kahle kukagesi kukhuthaza ukudluliswa kwamandla okusebenzayo, okuholela ekushiseleleni kwamabala asebenza kahle futhi aqine.
Ukuqinisekisa Ukwakheka Okungaguquki Kwe-Nugget:
Ukusetshenziswa kwamandla okulayisha kuqala kusiza ukuqinisekisa ukwakheka kwe-weld nugget engaguquki futhi echazwe kahle.Ukulayisha kuqala kucindezela izingcezu zokusebenza, kunciphisa ukumelana nokuxhumana futhi kuvumela ukukhiqizwa okungcono kokushisa endaweni obonakalayo.Lokhu kucindezelwa okulawulwayo kusiza ukwakheka kwendawo ethembekile yokuhlanganisa, ebonakala ngokubopha okufanele kanye nobuqotho be-metallurgical.
Ukunciphisa Izimpawu Ze-Electrode:
Ukulayisha kuqala kunganciphisa ukwakheka kwamamaki e-electrode endaweni yokusebenza.Uma ama-electrode elayishwe kusengaphambili kahle, ingcindezi isatshalaliswa ngokulinganayo, kunciphisa amathuba okuhlehlisa endaweni noma ukumakwa okubangelwa amandla amaningi.Lokhu kusiza ukulondoloza ukubukeka kobuhle bezingxenye ezishiselwe.
Ukukhuthaza Amandla Weld Nokuqina:
Ukusetshenziswa kwamandla okulayisha kuqala kukhuthaza amandla onke kanye nokuqina kwe-spot weld.Ngokuqinisekisa ukuqondanisa okufanele, ukuqhutshwa kukagesi, kanye nokwakheka kwe-nugget, ukulayisha kuqala kunomthelela ekushiseleni okunezakhiwo ezithuthukisiwe zemishini, njengokushuba okuphezulu namandla okugunda.Lokhu kubaluleke kakhulu ezinhlelweni zokusebenza lapho ubuqotho be-weld nokusebenza kwesikhathi eside kubalulekile.
Ukulayisha kuqala kudlala indima ebalulekile ekushiseleni indawo ye-medium frequency inverter.Iqinisekisa ukuqondanisa kahle kwe-electrode, ithuthukisa ukuhamba kukagesi, ikhuthaza ukwakheka kwe-nugget okungaguquki, inciphisa amamaki e-electrode, futhi inikele emandleni e-weld nokuqina.Ngokuhlanganisa ukulayisha kuqala njengomkhuba ojwayelekile, opharetha bangakwazi ukuzuza ukushiselwa kwendawo kwekhwalithi ephezulu ngokuthembeka okuthuthukisiwe, izakhiwo zokukhanda, nokusebenza kukonke.
