Ts'ebetso ena e itšetlehile ka taolo e nepahetseng ea li-parameter tse fapaneng, e 'ngoe ea tsona ke motlakase oa inter-electrode. Sengoliloeng sena, re tla hlahloba bohlokoa ba ho lekola motlakase oa li-inter-electrode mochining oa welding oa ho hanyetsa le hore na o kenya letsoho joang ho boleng le katleho ea ts'ebetso ea welding.
Resistance spot welding ke mokhoa o kenyelletsang ho fetisa motlakase ka li-electrode tse peli ho theha weld ea lehae, e phahameng ea mocheso lipakeng tsa likotoana tse peli tsa tšepe. Li-electrode li kopana le li-workpieces, 'me phallo ea hona joale e hlahisa mocheso, e leng se etsang hore litšepe li qhibilihe le ho kopanya hammoho. Ts'ebetso ena e sebelisoa hangata indastering ea likoloi, ea sefofane, le lisebelisoa tsa elektroniki, har'a tse ling.
Bohlokoa ba Inter-Electrode Voltage
Motlakase oa li-inter-electrode, o tsejoang hape e le motlakase oa welding, o bapala karolo ea bohlokoa ho lekanyeng boleng ba weld. Ke motlakase o sebelisoang lipakeng tsa li-electrode tse peli tsa welding nakong ea ts'ebetso ea welding. Ho beha leihlo voltage ena ho bohlokoa ka mabaka a 'maloa:
1. Taolo ea Boleng ba Weld:Motlakase oa li-inter-electrode o ama ka ho toba mocheso o hlahisoang sebakeng sa weld. Ka ho beha leihlo le ho laola motlakase ona, bahlahisi ba ka etsa bonnete ba hore li-welds li finyella litekanyetso tsa boleng tse lakatsehang. Ho fapana ha motlakase ho ka lebisa ho li-welds tse sa tsitsang, tse ka bakang manonyeletso a fokolang kapa bofokoli.
2. Tšebelisano 'moho:Lisebelisoa tse fapaneng li hloka litlhophiso tse khethehileng tsa motlakase bakeng sa welding e nepahetseng. Ho beha leihlo motlakase oa li-inter-electrode ho lumella basebelisi ho fetola litlhophiso ho latela lisebelisoa tse kopantsoeng, ho netefatsa tlamo e tšepahalang ntle le ho senya li-workpieces.
3. Ts'ebetso e Atlehang:Ho boloka motlakase o tsitsitseng oa inter-electrode ho matlafatsa ts'ebetso ea ts'ebetso ea welding. E fokotsa tlhokahalo ea liphetoho tsa matsoho le ho sebetsa bocha, e lebisang ho tlhahiso e phahameng le litšenyehelo tse tlase tsa tlhahiso.
4. Electrode Wear:Ha nako e ntse e ea, li-electrode lia theoha ka lebaka la maemo a feteletseng a ho cheselletsa letheba. Ho beha leihlo matla a motlakase ho ka thusa ho lemoha mefokolo e ka bonts'ang ho roala ha li-electrode. Ho lemoha kapele ho lumella ho nkeloa sebaka ka nako, ho thibela mefokolo ho li-welds.
5. Polokeho:Voltage e feteletseng e ka lebisa ho ho cheseha ho feteletseng, ho ka bakang likotsi tsa polokeho tikolohong ea welding. Ho beha leihlo motlakase ho thusa ho boloka maemo a bolokehileng a ts'ebetso, ho sireletsa lisebelisoa le basebetsi.
Mekhoa ea ho Hlokomela
Ho na le mekhoa e fapaneng ea ho lekola motlakase oa li-inter-electrode mochining oa welding oa ho hanyetsa:
1. Limithara tsa Voltage:Digital voltage metres hangata e sebelisoa ho fana ka lipalo tsa motlakase oa nako ea nnete nakong ea ts'ebetso ea welding. Limithara tsena li ka kopanngoa le thepa ea ho cheselletsa bakeng sa ho beha leihlo nako le nako.
2. Ho Rekoa ha Boitsebiso:Mechini e meng e tsoetseng pele ea welding e na le bokhoni ba ho rekota data. Ba rekota data ea voltage ha nako e ntse e ea, e lumella basebelisi ho sekaseka mekhoa le ho etsa liphetoho ha ho hlokahala.
3. Litlhokomeliso:Mechini ea li-welding e ka ba le lialamo kapa litemoso tse qalang ha motlakase o feta kapa o oela ka tlase ho menyako e behiloeng esale pele. Maikutlo ana a potlakileng a thusa ho thibela mathata a ho cheselletsa.
Ho lekola motlakase oa li-inter-electrode mochining oa ho tjheselletsa sebaka ke karolo ea bohlokoa ea ho netefatsa li-welds tsa boleng bo holimo, ho ntlafatsa ts'ebetso e ntle, le ho boloka polokeho ts'ebetsong ea welding. Ka ho kenya ts'ebetsong mekhoa e sebetsang ea ho lekola motlakase, bahlahisi ba ka ntlafatsa ts'epahalo ea li-welds tsa bona mme ba fumana liphetho tse tsitsitseng, tsa boleng bo holimo lits'ebetsong tse fapaneng.
