Resistance spot welding ke mokhoa o sebelisoang haholo ho kopanya liindasteri tse fapaneng, haholo indastering ea likoloi le tsa lifofane. Ts'ebetso ena e kenyelletsa ho sebelisa motlakase oa motlakase le khatello ho theha maqhama a matla pakeng tsa maqephe a tšepe kapa likaroloana. Ntlha e 'ngoe ea bohlokoa e atisang ho hlahisa lipotso ke karolo ea hona joale le motlakase ho khethollang boleng le katleho ea li-welds. Sehloohong sena, re tla hlahloba phello ea litlhophiso tsa hona joale le tsa voltage ho resistance spot welding.
Ho utloisisa Resistance Spot Welding
Pele u kenella ka har'a tšusumetso ea hona joale le ea motlakase, ho bohlokoa ho utloisisa metheo ea "resistance spot welding". Ts'ebetsong ena, libaka tse peli tsa tšepe lia kopana 'me li kenngoa ka matla a motlakase. Hona joale ena e phalla ka tšepe 'me e hlahisa mocheso ka lebaka la ho hanyetsa ha eona. Mocheso o qhibilihisa karolo e nyenyane ea tšepe, 'me o etsa lesela le qhibilihileng le pholileng le ho tiea ho etsa weld.
Karolo ea Hona Joale
Boemo ba hona joale ba ho tjheseletsa sebaka sa ho hanyetsa bo bapala karolo ea bohlokoa ho khetholla boleng ba weld. E ama sekhahla sa ho futhumatsa, boholo ba nugget, le matla a bond ka kakaretso. Mokhoa ona ke ona:
- Sekhahla sa ho futhumatsa:Maemo a phahameng a hona joale a lebisa lebelong la ho futhumatsa ka potlako. Sena se ka ba molemo bakeng sa lisebelisoa tse tšesaane kaha se fokotsa ho qhala ha mocheso 'me se fella ka sebaka se senyenyane se amehileng ke mocheso. Leha ho le joalo, bakeng sa lisebelisoa tse teteaneng, metsi a feteletseng a ka baka ho chesa kapa ho fafatsa.
- Boholo ba Nugget:Hona joale e susumetsa boholo ba nugget e entsoeng ka ho qhibiliha nakong ea ho cheselletsa. Maemo a holimo a hona joale a atisa ho etsa li-nuggets tse kholoanyane. Boholo ba nugget bo bohlokoa hobane bo ama ka kotloloho matla a lenonyeletso. Ho haella ha hona joale ho ka lebisa ho li-nuggets tse fokolang, tse fokolang, tse senyang botšepehi ba weld.
- Matla a Bond:Boleng ba weld bo amana haufi-ufi le hona joale. Maemo a hona joale a fetotsoeng hantle a netefatsa weld e matla le e tšoarellang. Ho kheloha ho tloha moeling oa hona joale o khothalletsoang ho ka lebisa litlamong tse fokolang le ho fokotsa botšepehi ba sebopeho.
Karolo ea Voltage
Voltage, mmoho le ea hajoale, e bapala karolo e tlatselletsang ho tjheseletsa sebakeng sa ho hanyetsa:
- Arc Initiation:Voltage e na le boikarabelo ba ho qala arc pakeng tsa electrode le workpiece. E hloka ho lekana ho hlola khanyetso ho sebopeho sa electrode-workpiece. Matla a tlase a ka baka li-arcs tse sa tsitsang le boleng bo tlase ba weld.
- Taolo ea Weld Pool:Voltage e boetse e ama sebopeho le botsitso ba letamo la weld. E thusa ho laola ho phalla ha tšepe e qhibilihisitsoeng le ho netefatsa kabo e tšoanang, ho thibela ho se tloaelehe ha lifaha tsa weld.
Optimizing Current le Voltage
Ho fihlella li-welds tsa boleng bo holimo tsa ho hanyetsa, ho bohlokoa ho ntlafatsa maemo a hajoale le a voltage. Sena se kenyelletsa ho nahana ka lintlha tse kang botenya ba thepa, mofuta oa tšepe le moralo oa li-electrode. Hangata bahlahisi ba fana ka litataiso le likhothaletso bakeng sa lisebelisoa tse ikhethileng le lits'ebetso.
Qetellong, hona joale le voltage ke likarolo tsa bohlokoa ho tjheseletsa sebakeng sa ho hanyetsa. Ho lokisa litlhophiso tsena hantle ho bohlokoa ho hlahisa li-welds tse tšepahalang le tse tšoarellang. Ho kheloha ho tsoa ho litekanyetso tse khothalelitsoeng ho ka baka bofokoli, ho fokotsa matla a tlamo, le ho hloleha ho ka bang teng ha sebopeho. Ka hona, ho utloisisa kamano lipakeng tsa sephetho sa hajoale, voltage le welding ho bohlokoa bakeng sa ho netefatsa ts'ebetso ea ts'ebetso ea "resistance spot welding" liindastering tse fapaneng.
