Spot welding ke mofuta oa thekenoloji ea tjheseletsa e nang le histori e telele, e entsoeng ka likarolo tsa ho tjheseletsa tse kopantsoeng ka lenonyeletso la lap le ho hatelloa pakeng tsa li-electrode tse peli, 'me li sebelisa mocheso oa ho hanyetsa ho qhibiliha tšepe ea motheo ho etsa sebaka sa ho tjheseletsa.
Likarolo tsa tjheseletsa li hokahane ke motheo o monyenyane o entsoeng ka ho qhibilihisoa, o lokelang ho ajoa ka mokhoa o lekanang le o lekanang holim'a bonding holim'a li-welds tse peli, 'me o na le litšobotsi tsa botekgeniki tsa ho cheselletsa tlas'a nako e phahameng, nako e khutšoanyane le khatello.
Spot tjheseletsa ke mocheso-mochini (matla) kopanetsweng khato ea tshebetso tjheseletsa, ho ea ka mofuta oa phepelo ea matla a ka aroloa ka lehlakoreng le le leng tjheseletsa le habeli-lehlakoreng tjheseletsa, ka tjheseletsa ka nako e khutšoanyane, kahoo phahameng bokgoni. Mocheso o tsepamisitsoe karolong e itseng, thepa e cheselitsoeng ha e hlahe ka seoelo deformation ea mocheso, 'me boleng ba welding bo botle. Kaha ke tjheseletso e iketsang, mang kapa mang a ka tjheseletsa, mme ha ho hlokahale tshebetso e hlwahlwa.
Bohlale ba ho hlophisoa ha letheba la welding eamochini o tjheseletsang letheba la maqhubu a mahareng: Sebopeho sa tjheseletsa sa Spot hangata se entsoe ka likhokahano tse ngata, tlhophiso ea eona hangata e na le mela e le 'ngoe, ka linako tse ling e ka ba mela e mengata, ka mola o le mong, lenonyeletso le le leng le le leng ho kenyelletsa khatello ea ho kuta, empa hape e jara khatello ea maikutlo e bakoang ke matla a eccentric. , sebakeng sa marang-rang a marang-rang a marang-rang, khatello ea maikutlo e nyane, lipatlisiso li bontša hore palo ea manonyeletso a solder ho feta 3 ha e utloahale, hobane mela e fetang 3 e ke ke ea eketsa matla a ho jara.
Ka nako e ts'oanang, hoa lokela ho hlokomeloa hore mola o le mong oa letheba tjheseletsa manonyeletso ke ke ha khoneha ho finyella matla a lenonyello le tšepe botlaaseng, feela tšebeliso ea mela e mengata (mela 3) lokisetsa solder manonyeletso, ka ntlafatsa tshusumetso. ea leeme matla toche, fokotsa khatello ea kelello mahloriso coefficient, haeba ho sebelisa staggered mola mokhoa, boemo bo tla ba molemo, ka khopolo, u ka fumana letheba welded kopanetsweng ka matla a tšepe botlaaseng.
