Spot welding ke mokhoa o sebelisoang haholo indastering ea tlhahiso, e tsejoang ka katleho le lebelo la ho kopanya lisebelisoa tsa tšepe. Leha ho le joalo, li-welding workpieces tsa botenya bo sa lekanang le lisebelisoa tse fapaneng e ka ba mosebetsi o boima. Sehloohong sena, re tla hlahloba mekhoa le mehopolo ea ho bona hantle li-welding tse joalo.
1. Khetho ea Lintho:
Pele u kenella ka har'a ts'ebetso ea welding, ho bohlokoa ho khetha li-electrode tse nepahetseng tsa welding le litlhophiso tsa lisebelisoa tse kopantsoeng. Litšepe tse fapaneng li na le thepa e fapaneng ea conductivity le ea ho senya mocheso, e ka amang boleng ba weld. Mohlala, haeba u cheselletsa tšepe ho aluminiamo, u tla hloka li-electrode tse khethehileng tse etselitsoeng litšepe tse sa tšoaneng.
2. Mekhahlelo ea Welding:
Lintlha tse ka sehloohong tsa ho tjheseletsa ha letheba ke nako ya welding, nako ya welding le matla a electrode. Litekanyetso tsena li tlameha ho fetoloa ho latela botenya le mofuta oa thepa. Lisebelisoa tse teteaneng hangata li hloka maqhubu a phahameng a ho tjheseletsa le linako tse telele tsa ho tjheseletsa. Bakeng sa lisebelisoa tse sa tšoaneng, ho fumana tekanyo e nepahetseng ke habohlokoa ho qoba ho tjheseletsa ho feta tekano kapa ka tlaase ho tjheseletsa.
3. Moralo oa Electrode:
Meetso e tloahelehileng ea li-electrode e ka thusa ho tsamaisa matla a ho cheselletsa ka ho lekana holim'a li-workpieces, leha li na le botenya bo fapaneng. Mohlala, eleketrode e hatetsoeng e nang le bophara bo boholo ka lehlakoreng le leng e ka sebelisoa ho netefatsa weld e nepahetseng holim'a thepa e teteaneng ha e ntse e thibela ho chesoa ho e tšesaane.
4. Tack Welding:
Tack welding e kenyelletsa ho etsa li-welds tse nyane, tsa pele sebakeng sa mahlale haufi le lenonyeletso ho tšoara lisebelisoa tsa mosebetsi hammoho. Sena se ka ba molemo haholo-holo ha u sebetsana le thepa ea botenya bo sa tšoaneng. Li-welds tsa Tack li netefatsa hore li-workpiece li lula li hokahane nakong ea ts'ebetso ea ho qetela ea welding.
5. Tatelano ea Welding:
Tatelano eo o tjheseletsang lisebelisoa tse fapaneng le eona e ka ama boleng ba lenonyeletso. Hangata ho eletsoa hore u qale ka lintho tse thinnest ebe u fallela ho tse teteaneng. Sena se thibela mocheso o feteletseng oa mocheso linthong tse tšesaane, tse ka lebisang ho cheso kapa ho sotha.
6. Teko le Tlhahlobo:
Kamora ho qeta weld, ho bohlokoa ho hlahloba lenonyeletso bakeng sa boleng. Mekhoa e fapaneng ea tlhahlobo e sa senyeheng, joalo ka tlhahlobo ea pono, tlhahlobo ea ho kenella ka dae, kapa tlhahlobo ea X-ray, e ka sebelisoa ho netefatsa bots'epehi ba weld.
7. Boikoetliso le Koetliso:
Ho cheselletsa thepa e sa tšoaneng le li-workpieces tsa botenya bo sa lekanang e ka ba tsebo e rarahaneng. Koetliso e lekaneng le boikoetliso li bohlokoa bakeng sa li-welders ho nts'etsapele boitseanape bo hlokahalang ho lula ba hlahisa manonyeletso a boleng bo holimo maemong a joalo.
Qetellong, li-welding workpieces tsa botenya bo sa lekaneng le lisebelisoa tse fapaneng tse nang le mochini oa ho tjheseletsa letheba li hloka ho nahanoa ka hloko ka lisebelisoa, litekanyetso tsa tjheseletsa, moralo oa li-electrode, le tatelano ea tjheseletsa. Ka ho latela litataiso tsena le ho tsetela thepa e nepahetseng, bahlahisi ba ka fihlela li-welds tse matla le tse tšepahalang lits'ebetsong tse fapaneng, leha ba tobane le metsoako e thata ea thepa.
