Resistance spot welding ke mokhoa o sebelisoang haholo liindastering tse fapaneng, ho kenyeletsoa likoloi, tsa ho etsa le tsa kaho. Mokhoa ona o kenyelletsa ho kopanya likotoana tse peli kapa ho feta tsa tšepe hammoho ka ho sebelisa mocheso le khatello ka tšebeliso ea matla a motlakase. Leha ho le joalo, ho netefatsa tšireletseho le ho finyella li-welds tsa boleng bo botle, basebetsi ba tlameha ho khomarela litataiso tse khethehileng ha ba sebelisa mochine oa ho tjheselletsa sebaka sa ho hanyetsa. Sehloohong sena, re tla hlahloba lintlha tsa bohlokoa bakeng sa ts'ebetso e sireletsehileng le e sebetsang.
1. Mehato ea Tšireletso:
Tšireletseho e lokela ho ba ntho ea bohlokoa ka ho fetisisa ha u sebelisa mochine ofe kapa ofe, 'me letheba la ho tjheseletsa ha ho na mokhelo. Litlhokomelo tse ling tsa tšireletso ke tsena:
- Apara PPE e nepahetseng: Kamehla u roale thepa e hlokahalang ea ho itšireletsa, ho akarelletsa likhalase tsa tšireletso, litlelafo tse chesehang le liaparo tse sa cheng.
- Moea oa moea: Netefatsa hore sebaka sa mosebetsi se na le moea o lekaneng ho qhala mosi le ho thibela ho pepesehela likhase tse kotsi.
- Tšireletseho ea Motlakase: Lekola likhokahano tsa motlakase tsa mochini le ho thella fatše ho qoba likotsi tsa motlakase.
- Tšireletseho ea Mollo: E-ba le lisebelisoa tsa ho tima mollo tse fumanehang habonolo maemong a tšohanyetso.
2. Tlhahlobo ea Mochini:
Pele o qala ts'ebetso efe kapa efe ea ho tjheseletsa, hlahloba mochini oa welding ka botlalo:
- Li-electrode: Netefatsa hore li-electrode li hloekile ebile li tsamaisana hantle.
- Lithapo: Lekola lithapo tsa ho tjheseletsa ho bona matshwao leha e le afe a ho onala kapa a senyehileng.
- Khatello: Netefatsa hore li-setting tsa khatello li loketse thepa e cheselitsoeng.
- Mokhoa oa ho Pholisa: Netefatsa hore sistimi ea ho pholisa e sebetsa ka nepo ho thibela mocheso o feteletseng.
3. Tokisetso ea Lintho:
Ho lokisoa hantle ha thepa ho bohlokoa bakeng sa ts'ebetso e atlehileng ea tjheseletsa sebakeng:
- Botenya ba Lintho: Netefatsa hore lisebelisoa tse lokelang ho chesetsoa li na le botenya bo lekanang.
- Bohloeki ba Lintho: Tlosa litšila leha e le life, tse kang mafome, pente, kapa oli, holim'a tšepe.
4. Mekhahlelo ea Welding:
Ho bohlokoa ho khetha li-parameter tse nepahetseng bakeng sa ho fumana li-welds tse matla le tse tsitsitseng. Li-parameter tsena li kenyelletsa:
- Welding Current: Fetola hona joale welding ho ea ka thepa le botenya.
- Nako ea ho Welding: Beha nako ea ho cheselletsa ho fihlella ho kenella ho lakatsehang le matla a tlamo.
5. Mokhoa oa ho Welding:
Mokhoa oa welding o boetse o phetha karolo ea bohlokoa ho boleng ba weld:
- Electrode Placement: Beha li-electrode ka nepo ho netefatsa hore weld e sebakeng se lakatsehang.
- Tatelano ea Welding: Etsa qeto ea tatellano eo ho eona li-welds tse ngata li lokelang ho etsoa ho fokotsa ho sotha.
- Tlhokomelo: Tsoela pele ho beha leihlo ts'ebetso ea welding ho bona liphoso kapa liphoso.
6. Tlhahlobo ea Kamora ho Weld:
Kamora ho qeta ts'ebetso ea welding, hlahloba li-welds bakeng sa boleng:
- Tlhahlobo ea Pono: Lekola litšepe bakeng sa mefokolo leha e le efe, joalo ka mapetsong kapa ho kopana ho sa fellang.
- Teko e Senyang: Etsa liteko tse senyang, haeba ho hlokahala, ho netefatsa matla a li-welds.
Ka ho latela litataiso tsena le ho latela liprothokholo tsa polokeho, basebelisi ba ka netefatsa ts'ebetso e bolokehileng le e sebetsang ea mochini oa tjheseletsa oa sebaka sa ho hanyetsa. Sena ha se sireletse mokhanni feela empa se boetse se tiisa boleng le ho tšepahala ha likarolo tse cheselitsoeng, tse tlatsetsang katlehong e akaretsang ea ts'ebetso ea tlhahiso.
