Resistance spot welding ke mokhoa o sebelisoang haholo tlhahisong, haholo indastering ea likoloi le ea sefofane, moo tlhoko ea li-welds tse matla le tse tšepahalang e leng tsa bohlokoa haholo. Ts'ebetso ena e kenyelletsa ts'ebeliso ea motlakase le khatello ea ho kopanya likotoana tse peli tsa tšepe hammoho. Ntho e 'ngoe ea bohlokoa ka ho fetisisa ea ho cheselletsa sebaka sa ho hanyetsa ke nako ea ho cheselletsa, e bapalang karolo ea bohlokoa ho khetholla boleng le matla a weld. Sehloohong sena, re tla hlahloba kamano e rarahaneng pakeng tsa nako ea ho tjheseletsa le ho falla ha electrode, ho fana ka leseli ho lintlha tse susumetsang matla ana.
Resistance spot welding, eo hangata ho thoeng ke letheba la tjheseletsa, ke ts'ebetso e kopanyang e itšetlehileng ka tšebeliso ea sebaka sa mocheso e hlahisoang ke ho hanyetsa motlakase sebakeng sa ho kopana pakeng tsa likotoana tse peli tsa tšepe. Li-electrode li sebelisetsoa ho sebelisa khatello le hona joale ho etsa nugget ea weld. Nako ea phallo ea hona joale, e tsejoang e le nako ea ho cheselletsa, ke ntlha ea bohlokoa katlehong ea ts'ebetso ea welding.
Nako ea ho Welding le Phello ea eona
Nako ea ho tjheseletsa e ama ka ho toba boholo le boleng ba nugget ea weld. Linako tse telele tsa ho cheseletsa hangata li baka litšepe tse kholoanyane le tse atolositsoeng, athe linako tse khutšoane li hlahisa litšepe tse nyane, tse sa tebang haholo. Kamano pakeng tsa nako ea ho tjheseletsa le ho falla ha elektrode e rarahane mme e ipapisitse le lintlha tse fapaneng, ho kenyeletsoa thepa ea thepa, geometry ea electrode, le hona joale oa welding.
Lintlha tse Susumetsang Phallo ea Electrode
a. Botenya ba Lintho:Lisebelisoa tse teteaneng hangata li hloka nako e telele ea ho cheselletsa ho netefatsa ho kenella le ho kopanngoa hantle. Ha nako ea welding e ntse e eketseha, phallo ea li-electrode e boetse e eketseha ho amohela mocheso o eketsehileng le khatello e hlokahalang.
b. Matla a Electrode:Matla a sebelisoang ke li-electrode a ama ho falla ha electrode. Matla a phahameng a li-electrode a ka lebisa ho motsamao o potlakileng oa li-electrode ka lebaka la khatello e ntseng e eketseha, e bakang linako tse khuts'oane tsa ho cheselletsa.
c. Moralo oa Electrode:Sebopeho le boholo ba li-electrode li phetha karolo ea bohlokoa. Meralo e fapaneng ea li-electrode e kanna ea ba le litlamorao tse fapaneng mabapi le phallo ea li-electrode, leha e le ka nako e ts'oanang ea tjheseletsa.
d. Hona Joale Welding:The tjheseletsa matla a hona joale susumetsa lebelo leo chesella nugget theha. Maqhubu a phahameng hangata a fella ka phallo e potlakileng ea li-electrode le linako tse khuts'oane tsa ho cheselletsa.
Ho utloisisa kamano pakeng tsa nako ea ho cheselletsa le ho falla ha li-electrode ho bohlokoa bakeng sa ho fihlela li-welds tse tsitsitseng le tsa boleng bo holimo. Bahlahisi ba ka laola kamano ena ka ho fetola liparamente tsa welding le ho khetha ka hloko lisebelisoa le meralo ea li-electrode.
Sebakeng sa ho tjheseletsa letheba la ho hanyetsa, kamano pakeng tsa nako ya ho tjheseletsa le ho falla ha electrode ke ntho e matla le e nang le mefuta e mengata. Joalo ka ha re se re hlahlobile, lintlha tse kang botenya ba thepa, matla a li-electrode, moralo oa li-electrode, le hona joale oa welding kaofela lia sebetsa. Ho tseba kamano ena ho bohlokoa bakeng sa ho hlahisa li-welds tse tšepahalang le tse matla lits'ebetsong tse fapaneng tsa indasteri. Bafuputsi le baenjiniere ba ntse ba tsoela pele ho etsa lipatlisiso le ho ntlafatsa khokahano ena ho sutumelletsa meeli ea se ka khonehang lefatšeng la ho cheselletsa letheba.
