Tlhahlobo e Tebileng ea Ts'ebetso ea Motlakase le Thermal ea Resistance Spot Welding Materials

Resistance spot welding ke mokhoa o sebelisoang haholo tlhahisong, haholo indastering ea likoloi le tsa lifofane. Katleho ea ts'ebetso ena e itšetlehile haholo ka motlakase le mocheso oa motlakase oa thepa e amehang. Sengoliloeng sena, re tla shebana le lefats'e le rarahaneng la thepa ena ea thepa le likarolo tsa eona tsa bohlokoa ho tjheseletsa libaka tsa ho hanyetsa.

Tšebeliso ea Motlakase: Senotlolo sa ho Cheselletsa ka Botle

1. Utloisisa Conductivity Motlakase: Conductivity ea motlakase ke tekanyo ea bokhoni ba thepa ea ho tsamaisa motlakase. Ha ho cheselleloa sebaka, lisebelisoa (hangata litšepe) li tlameha ho tsamaisa motlakase hantle ho hlahisa mocheso sebakeng sa weld. Lisebelisoa tse nang le motlakase o phahameng oa motlakase, joalo ka koporo le aluminium, li khethoa bakeng sa li-electrode hobane li nolofatsa ho phalla ha motlakase, ho theha mohloli oa mocheso o tsitsitseng sebakeng seo ho kopanang ho sona.
2. Seabo Molokong oa Mocheso: Ha motlakase o feta ka har'a lisebelisoa tsa mosebetsi, ho hanyetsa ha motlakase ho etsa hore ba futhumale ka lebaka la mocheso oa Joule. Mocheso ona oa sebakeng seo o nolofatsa lisebelisoa, o li lumella hore li kopane hammoho sebakeng sa weld. Motlakase o phahameng oa motlakase ho li-electrode o netefatsa tahlehelo e fokolang ea mocheso, e leng ho etsang hore ts'ebetso ea welding e atlehe haholoanyane.
3. Khetho ea Lintho: Koporo le li-alloys tsa eona, tse kang koporo-chromium le koporo-zirconium, ke likhetho tse ratoang bakeng sa li-electrode tsa welding ka lebaka la motlakase oa tsona o babatsehang oa motlakase. Leha ho le joalo, lisebelisoa tsa elektrode le tsona li lokela ho mamella khatello ea maikutlo le ho roala nakong ea ts'ebetso ea welding.

Thermal Conductivity: Ho leka-lekanya Kabo ea Mocheso

1. Ho utloisisa Thermal Conductivity: Thermal conductivity e lekanya bokhoni ba thepa ho tsamaisa mocheso. Ho tjheseletsa sebakeng sa ho hanyetsa, ho bohlokoa ho laola kabo ea mocheso ho thibela ho soahlamana kapa ho senya lisebelisoa tsa mosebetsi. Theko e tlaase ea mocheso linthong tse cheselitsoeng e thusa ho ba le mocheso ka har'a sebaka sa welding.
2. Ho Thibela ho Feta ho Feta: Lisebelisoa tse nang le conductivity e phahameng ea mocheso, joaloka koporo, li ka tlosa mocheso kapele ho tloha sebakeng sa welding. Le ha thepa ena e le molemo bakeng sa li-electrode ho thibela ho futhumala ho feteletseng, ho bohlokoa ho sebelisa lisebelisoa tse nang le conductivity e tlase ea mocheso bakeng sa li-workpieces. Sena se tiisa hore mocheso o tsepamisitsoe sebakeng sa weld, ho lumella ho kopanya ka katleho ntle le ho hasana ho feteletseng ha mocheso.
3. Ho Ntlafatsa Metsoako ea Lintho: Ho fumana tekanyo e nepahetseng pakeng tsa conductivity e phahameng ea motlakase ho li-electrode le conductivity e tlaase ea mocheso ka har'a lisebelisoa ke habohlokoa bakeng sa katleho ea ho hanyetsa letheba la tjheseletsa. Hangata lienjineri li etsa liteko ka mefuta e fapaneng ea lisebelisoa ho fumana tekanyo e nepahetseng bakeng sa lits'ebetso tse khethehileng tsa welding.

Ho tjheseletsa sebakeng sa ho hanyetsa, ho utloisisa conductivity ea motlakase le ea mocheso oa thepa ho bohlokoa bakeng sa ho fumana li-welds tse tšepahalang le tsa boleng bo holimo. Motlakase oa motlakase o netefatsa phallo e nepahetseng ea hona joale bakeng sa tlhahiso ea mocheso, ha ho laola mocheso oa mocheso ho thusa ho boloka mocheso o loketseng oa mocheso sebakeng sa welding. Lienjiniere le li-welders li tlameha ho khetha ka hloko le ho leka-lekanya thepa ena ea thepa ho fihlela sephetho se lakatsehang lits'ebetsong tse fapaneng tsa tlhahiso.
