Projection welding ke mokhoa o sebelisoang haholo liindastering tse fapaneng bakeng sa ho kopanya likarolo tsa tšepe. Ts'ebetso ea welding e kenyelletsa ho sebelisa khatello le motlakase ho theha maqhama a matla lipakeng tsa likarolo. Ntho e 'ngoe ea bohlokoa ka ho fetisisa ea welding ke nako ea ho cheselletsa, e ka susumetsang boleng ba weld haholo. Sengoliloeng sena se hlahloba litlamorao tsa nako ea ho cheselletsa tšebetsong ea projeke ea welding ea li-welder tse mahareng tsa maqhubu.
Selelekela: Projection welding, subtype of resistance welding, e kenyelletsa ho thehoa ha li-welds lintlheng tse khethehileng holim'a tšepe moo ho nang le likhakanyo kapa li-embossments. Likhakanyo tsena li lebisa tlhokomelo ea hona joale le khatello, e bakang ho futhumatsa le ho kopanngoa ha libaka. Medium frequency spot welders hangata e sebelisoa ka lebaka la ts'ebetso ea tsona e sebetsang le ho feto-fetoha ha maemo. Nako ea ho cheselletsa, e hlalosoang e le nako eo hona joale e phallang ka har'a weld, ke ntlha ea bohlokoa ho fihlella litšepe tse tsitsitseng le tse matla.
Liphello tsa Nako ea ho Welding Boleng ba Weld: Nako ea ho cheselletsa e na le tšusumetso e kholo ho boleng ba li-welds tsa projeke. Nako e sa lekaneng ea welding e ka lebisa ho fusion e sa fellang, e leng se bakang manonyeletso a fokolang. Ka lehlakoreng le leng, nako e feteletseng ea tjheseletsa e ka baka ho fetella, ho lebisa ho deformation esita le ho chesoa ke likarolo. Ho bohlokoa ho tseba nako e nepahetseng ea welding e lekanyang lintlha tsena ho fihlela li-welds tse matla, tse tšepahalang.
Sebaka se Angoang ke Mocheso (HAZ): Nako ea ho cheselletsa e ama ka kotloloho boholo ba sebaka se anngoeng ke mocheso (HAZ). Nako e khuts'oane ea welding e fokotsa ho kenya mocheso, ho fokotsa boholo ba ho hasana ha mocheso linthong tse potolohileng. Ka lehlakoreng le leng, linako tse telele tsa welding li eketsa HAZ, tse ka 'nang tsa ama thepa ea thepa le botšepehi ba sebopeho sa motsoako. Kahoo, ho khetha nako e nepahetseng ea ho cheselletsa ho bohlokoa bakeng sa ho laola HAZ le ho boloka thepa e lakatsehang ea mochini.
Ts'ebetso e Atlehang le Ts'ebetso: Ho fumana tekano e nepahetseng lipakeng tsa nako ea welding, boleng ba weld, le ts'ebetso ea ts'ebetso ho bohlokoa. Linako tse telele tsa ho cheseletsa li ka lebisa ho sekhahla sa tlhahiso butle, ha nako e khuts'oane e ka baka liphoso. Baetsi ba lokela ho ntlafatsa liparamente tsa welding ho netefatsa li-welds tsa boleng bo holimo ntle le ho senya tlhahiso ea tlhahiso.
Mokhoa oa Teko: Ho fumana nako e nepahetseng ea tjheseletsa, lithuto tsa liteko li ka etsoa. Linako tse fapaneng tsa welding li ka lekoa ha ho ntse ho bolokoa liparamente tse ling kamehla. Ho ka hlahlojoa boleng ba weld, matla a mochini, le boholo ba HAZ. Mekhoa ea sejoale-joale e kang tlhahlobo e sa senyeheng le tlhahlobo ea metallurgic e ka fana ka leseli la bohlokoa mabapi le litšobotsi tsa weld.
Sebakeng sa projeke ea ho tjheseletsa ho sebelisa li-welders tsa maqhubu a mahareng, nako ea welding e ama boleng ba weld haholo, boholo ba HAZ, le katleho ea ts'ebetso ka kakaretso. Baetsi le bafuputsi ba tlameha ho sebelisana 'moho ho theha mekhoa e metle ea ho cheselletsa e fanang ka li-welds tse matla, tse tšepahalang ha li ntse li kopana le litlhoko tsa tlhahiso. Kutloisiso e phethahetseng ea hore na nako ea welding e ama ts'ebetso joang e tla kenya letsoho ho ntlafatseng boleng ba weld le bots'epehi ba sebopeho lits'ebetsong tse fapaneng tsa indasteri.
