Mid-frequency spot welding ke mokhoa o sebelisoang haholo liindastering tse fapaneng, joalo ka tsa likoloi le tsa tlhahiso, bakeng sa ho kopanya likarolo tsa tšepe. Ho netefatsa boleng ba manonyeletso ana a weld ho bohlokoa ho boloka botsitso ba sehlahisoa le polokeho. Sengoliloeng sena se tla shebana le tlhahlobo ea litaba tsa boleng bo tloaelehileng tse amanang le li-welding spots tsa bohareng ba maqhubu.
Taba ea Boleng ea 1: Weld Porosity Weld porosity e bolela ho ba teng ha li-voids tse nyenyane kapa likheo ka har'a motsoako o nang le weld, o ka fokolisang sebopeho le ho fokotsa botšepehi ka kakaretso ba weld. Lintlha tse 'maloa li ka kenya letsoho ho chesehele porosity, ho kenyelletsa khase e sirelletsang e sa lekaneng, li-parameter tse sa nepahalang tsa tjheseletsa, kapa litšepe tsa motheo tse silafetseng. Mehato e sebetsang ea taolo ea boleng, joalo ka ho beha leihlo khase le tlhokomelo ea kamehla ea lisebelisoa tsa ho cheselletsa, ke tsa bohlokoa ho rarolla bothata bona.
Taba ea Boleng ea 2: Weld Cracking Weld cracking, kapa ho thehoa ha mapetsong lenonyeletsong le cheselitsoeng, ke taba e 'ngoe e atileng ea boleng. E ka hlaha ka lebaka la ho pholile ka potlako ha chese, preheating e sa lekaneng, kapa maemo a phahameng a khatello ea maikutlo. Mehato ea thibelo e kang ho laola sekhahla sa ho pholisa, ho kenya ts'ebetsong mekhoa e nepahetseng ea ho futhumatsa pele, le ho sebelisa lisebelisoa tse loketseng tsa ho tlatsa li ka thusa ho fokotsa ho phatloha ha weld.
Taba ea Boleng ea 3: Ho Kena ho sa Feleng Ho kenella ka mokhoa o sa fellang ho etsahala ha weld e hlōleha ho finyella botenya bo feletseng ba thepa ea motheo, e leng se bakang motsoako o fokolang. Lintlha tse tlatsetsang tabeng ena li kenyelletsa hona joale oa welding o fosahetseng, boholo bo sa lokelang ba elektrode, kapa ho itokisa ka mokhoa o sa tloaelehang. Basebelisi ba lokela ho fumana koetliso e lekaneng 'me ba hlahlobe lisebelisoa tsa bona tsa ho cheselletsa litšepe khafetsa ho etsa bonnete ba hore ba kenella ka nepo le boleng bo lumellanang bo kopaneng.
Taba ea Boleng ba 4: Weld Spatter Weld spatter ke ejection ea likaroloana tsa tšepe tse qhibilihisitsoeng nakong ea ts'ebetso ea welding, e ka lebisang likotsing tsa polokeho le ho fokotsa aesthetics. Ho roala li-electrode ka nepo, ho boloka libaka tsa mosebetsi li hloekile, le ho lokisa liparamente tsa welding ho ka fokotsa ho hlaha ha weld spatter.
Taba ea Boleng ea 5: Electrode Wear Boemo ba li-electrode tsa ho tjheseletsa bo bapala karolo ea bohlokoa ho fihlelleng litšepe tsa boleng bo holimo. Ho roala ha elektrode, ho bakoang ke lintlha tse kang ho pholisa ho feteletseng kapa ho se pholile ka ho lekaneng, ho ka lebisa boleng bo sa tsitsang bo kopanetsoeng le litšenyehelo tse eketsehileng tsa tlhokomelo. Ho kenya tšebetsong li-electrode monitoring le linako tsa ho nchafatsa ho ka thusa ho rarolla bothata bona.
Qetello: Ho netefatsa boleng ba likhokahano tsa li-welding tse bohareng ba maqhubu ho bohlokoa bakeng sa ho boloka botsitso ba sehlahisoa le polokeho liindastering tse fapaneng. Ka ho sebetsana le litaba tse tloaelehileng tsa boleng tse kang weld porosity, cracking, ho kena ho sa fellang, weld spatter, le electrode wear, bahlahisi ba ka ntlafatsa mekhoa ea bona ea ho cheseletsa le ho hlahisa manonyeletso a tšepehang a boleng bo phahameng. Mehato e sebetsang ea taolo ea boleng, koetliso ea li-operator, le tlhokomelo ea kamehla ea lisebelisoa ke lintlha tsa bohlokoa ho finyella li-welds tse tsitsitseng, tsa boleng bo phahameng.
