Resistance spot welding ke mokhoa o sebelisoang haholo oa ho kopanya likarolo tsa tšepe liindastering tse fapaneng. Leha ho le joalo, taba e 'ngoe e tloaelehileng eo ho tobanoang le eona nakong ea ts'ebetso ena ke ho thehoa ha likoti tse cheselletsang kapa li-craters holim'a metsi a tjheselitsoeng. Likoti tsena ha li sekisetse botšepehi ba sebopeho sa weld feela empa hape li ama ponahalo ea eona. Sehloohong sena, re tla hlahloba mekhoa e meng ea ho fokotsa likoti tsa welding mochining oa ho tjheselletsa sebaka.
- Mekhatlo e nepahetseng ea Welding:Litokiso tse nepahetseng tsa li-parameter tsa welding li bohlokoa ho fokotsa likoti tsa welding. Mekhahlelo ena e kenyelletsa hona joale oa welding, nako ea welding, le matla a electrode. Ho thibela ho futhumala ho feteletseng le ho lelekoa ha thepa, ho bohlokoa ho fumana tekanyo e nepahetseng.
- Tlhokomelo ea Electrode:Kamehla hlahloba le ho boloka li-electrode tsa welding. Li-electrode tse senyehileng kapa tse tsofetseng li ka lebisa khatellong e sa lekanang, e bakang likoti tse chesehang. Fetola kapa u fetole li-electrode ha ho hlokahala.
- Sebaka se Hloekileng sa Mosebetsi:Netefatsa hore bokaholimo ba lisebelisoa tse tla chesetsoa bo hloekile ebile ha bo na litšila tse kang oli, mafome kapa pente. Libaka tse litšila li ka sitisa ts'ebetso ea welding mme tsa lebisa ho thehoeng ha likoti.
- Clamping e nepahetseng:Sireletsa li-workpieces hammoho ho etsa bonnete ba hore ho kopana le li-electrode le tšepe. Ho koala ho fokolang ho ka fella ka li-welds tse sa tsitsang le ho thehoa ha mekoti.
- Khetho ea Lintho:Khetha mofuta o nepahetseng oa lisebelisoa tsa elektrode le lisebelisoa tsa mosebetsi bakeng sa ts'ebeliso e khethehileng. Metsoako e meng e tloaetse ho theha mekoti ho feta e meng, kahoo khetha lisebelisoa tse tlatsanang hantle.
- Pulse Welding:Nahana ka ho sebelisa mekhoa ea ho cheselletsa pulse haeba e fumaneha mochining oa hau oa ho tjheseletsa. Pulse welding e ka thusa ho laola ho kenya mocheso le ho fokotsa menyetla ea likoti tsa ho cheselletsa.
- Tatelano ea Welding:Fetola tatellano ea li-welding ha ho khoneha. Ho fetola tatellano eo li-welds tse ngata li etsoang ka eona ho ka aba mocheso ka mokhoa o ts'oanang, ho fokotsa menyetla ea ho thehoa ha mekoti.
- Ho pholisa:Kenya ts'ebetsong mekhoa e nepahetseng ea ho pholisa ho laola sekhahla sa ho pholisa sebakeng sa weld. Pholiso e fokolang le e laoloang e ka thusa ho thibela ho tiea ka potlako hoo hangata ho lebisang ho thehoa ha mekoti.
- Taolo ea Boleng:Kamehla hlahloba likarolo tse cheselitsoeng ho tseba le ho rarolla likoti leha e le life hang-hang. Ho lemoha kapele ho ka thibela taba hore e se ke ea mpefala le ho beha boleng ba kakaretso ea weld kotsing.
- Koetliso le Tsebo:Netefatsa hore basebetsi ba koetlisoa ka mokhoa o lekaneng ho sebelisa mochini oa tjheseletsa oa sebaka sa ho hanyetsa. Basebelisi ba nang le litsebo ba hlomelloa hamolemo ho beha leihlo tšebetso le ho etsa liphetoho tsa nako ea nnete ho thibela bofokoli ba ho cheselletsa.
Qetellong, ho fokotsa likoti tsa welding sebakeng sa ho tjheseletsa sebakeng sa ho hanyetsa ho hloka motsoako oa tlhokomelo e nepahetseng ea lisebelisoa, ts'ebetso ea ts'ebetso le bokhoni ba ho sebetsa. Ka ho latela litataiso tsena, bahlahisi ba ka fumana li-welds tse matla, tse khahlisang haholoanyane, ho ntlafatsa boleng ba lihlahisoa tsa bona kaofela.
