Mechineng ea li-weld spot welding, ho thehoa ha libaka tsa weld ke ts'ebetso ea bohlokoa e khethollang boleng le matla a manonyeletso a weld. Ho utloisisa molao-motheo oa ho theha letheba la weld ho bohlokoa bakeng sa ho ntlafatsa liparamente tsa welding le ho fihlela li-welds tse tšepahalang le tse sa fetoheng. Sengoliloeng sena se fana ka kakaretso ea molao-motheo oa ho theha matheba a weld mochining oa welding oa maqhubu a mahareng a maqhubu a maqhubu, o fana ka leseli mabapi le lintlha tsa bohlokoa tse susumetsang ts'ebetso.
- Motlakase Resistance Heating: Theho ea matheba a weld ka har'a mechini ea welding ea maqhubu a mahareng e ipapisitse le ho futhumala ha motlakase. Ha mochini oa ho tjheseletsa o feta ka har'a li-workpieces tse lokelang ho kopanngoa, ho hanyetsa motlakase libakeng tsa ho kopana ho hlahisa mocheso. Ho futhumala hona ha libaka ho etsa hore tšepe e sehokelong e fihle sebakeng sa eona sa ho qhibiliha, e leng se etsang hore ho thehoe letamo le qhibilihisitsoeng.
- Kopo ea Khatello: Ka nako e le 'ngoe le mocheso oa ho hanyetsa motlakase, khatello e sebelisoa ho lisebelisoa tsa mosebetsi ka malebela a electrode. Khatello e thusa ho netefatsa kamano e haufi-ufi pakeng tsa li-workpieces, ho nolofalletsa ho fetisa mocheso le ho kopanya tšepe. E boetse e khothalletsa ho lelekoa ha litšila le li-oxide ho tloha sebakeng sa weld, ho lumella hore ho be le tlamo e hloekileng le e matla.
- Solidification le Fusion: Ha mocheso o thibelang motlakase le khatello o ntse o bolokoa, tšepe e qhibilihisitsoeng ka har'a letamo la weld e qala ho tiea. Ts'ebetso ea ho pholisa le ho tiisa e etsa hore tšepe e qhibilihisitsoeng e fetohe boemong bo tiileng, ho etsa maqhama a metallurgical pakeng tsa lisebelisoa tsa mosebetsi. Ho tiisa le ho kopanngoa ha tšepe e qhibilihisitsoeng ho etsa hore ho be le motsoako o matla le o tšoarellang oa weld.
- Lintlha tsa Weld Spot Formation: Lintlha tse 'maloa li susumetsa sebopeho sa matheba a weld ka har'a mochini oa welding oa maqhubu a mahareng. Lintlha tsena li kenyelletsa nako ea ho tjheseletsa, nako ea ho tjheseletsa, matla a electrode, lisebelisoa tsa electrode, lisebelisoa tsa workpiece, le maemo a holim'a metsi. Taolo e nepahetseng ea liparamente tsena e bohlokoa ho fihlela sebopeho se tsitsitseng sa weld le ho netefatsa boleng bo lakatsehang ba weld.
Sebopeho sa matheba a tjheseletsa mechineng ea tjheseletsa ea maqhubu a mahareng a maqhubu a mahareng e its'etleha holim'a melao-motheo ea ho futhumatsa motlakase, ts'ebeliso ea khatello le ho tiisa. Ho utloisisa lintlha tse susumetsang sebopeho sa weld spotting ho lumella basebelisi ho ntlafatsa liparamente tsa welding le ho netefatsa li-welds tse tšepahalang le tsa boleng bo holimo.
