Spot welding ke mokhoa oa ho tjheseletsa oa ho hanyetsa oo likarolo tsa tjheseletsa li bokelloang ka li-lap joints ebe li hatelloa pakeng tsa li-electrode tse peli, ho sebelisa mocheso oa ho hanyetsa ho qhibilihisa tšepe ea motheo ho etsa manonyeletso a solder.
Spot welding e sebelisoa haholo-holo likarolong tse latelang:
1. Ho kopana ha likarolo tse tšesaane tsa litempe tsa poleiti, joalo ka likoloi tsa makoloi, li-compartments, li-screener scale scales tsa tlhapi, joalo-joalo.
2. Letlapa le lesesaane le libopeho tsa tšepe tse bōpehileng joaloka le letlalo, joalo ka mabota a kariki le siling, liphanele tsa likariki tsa tereilara, li-funnels tse kopanyang, joalo-joalo.
3. Li-skrini, liforeimi tsa sebaka le litšepe tsa sefapano, joalo-joalo.
02.Dikarolo
Nakong ea ho tjheseletsa letheba, weldment e etsa motsoako o fetang 'me o hatelloa pakeng tsa li-electrode tse peli. Likarolo tsa eona tsa mantlha ke tse latelang:
1. Nakong ea ho cheselletsa letheba, nako ea ho futhumatsa ea sebaka sa ho hokahanya e khutšoanyane haholo 'me lebelo la welding le potlakile.
2. Spot welding e sebelisa matla a motlakase feela 'me ha e hloke lisebelisoa tsa ho tlatsa, flux, khase, joalo-joalo.
3. Boleng ba ho tjheseletsa letheba bo tiisitsoe haholo-holo ke mochine oa tjheseletsa oa letheba. E na le ts'ebetso e bonolo, tekanyo e phahameng ea ho sebelisa mechine le ho iketsetsa, le tlhahiso e phahameng.
4. Matla a tlase a mosebetsi le maemo a matle a ho sebetsa.
5. Kaha welding e phethoa ka nako e khutšoanyane 'me e hloka hona joale le khatello e kholo, taolo ea lenaneo la ts'ebetso e rarahane haholoanyane, mochine oa welding o na le matla a maholo a motlakase,' me theko ea thepa e batla e phahame.
6. Ho thata ho etsa liteko tse sa senyeheng tsa manonyeletso a solder.

03.Ts'ebetso ea ts'ebetso
Pele ho welding, bokaholimo ba workpiece bo tlameha ho hloekisoa. Phekolo ea ho hloekisa e atisang ho sebelisoa ke pickling, ke hore, e qala ho kenngoa ka sulfuric acid e futhumetseng ka motsoako oa 10%, ebe e hlatsuoa ka metsi a chesang. Ts'ebetso e khethehileng ea welding ke e latelang:
(1) Fepa motsoako oa workpiece pakeng tsa li-electrode tse ka holimo le tse ka tlaase tsa mochine oa tjheseletsa oa letheba le ho o koala;
(2) Ha motlakase o sebelisoa, libaka tsa ho kopana tsa lisebelisoa tse peli tsa mosebetsi li futhumatsoa, ka mokhoa o fokolang, 'me ho etsoa nugget;
(3) Boloka khatello ka mor'a hore motlakase o tima, e le hore nugget e qhibilihisitsoeng e pholile 'me e tiee tlas'a khatello ea ho etsa manonyeletso a solder;
(4) Tlosa khatello 'me u ntše workpiece.
04.Mabaka a susumetsang
Lintlha tse ka sehloohong tse susumetsang boleng ba welding li kenyelletsa nako ea ho tjheseletsa hona joale le ea matla, khatello ea electrode le shunt, joalo-joalo.
1. Hona joale welding le matla-ka nako
Ho ea ka boholo ba motlakase oa hona joale le bolelele ba matla-ka nako, welding ea letheba e ka aroloa ka mefuta e 'meli: gauge e thata le gauge e bonolo. Tlhaloso e fetisang motlakase o moholo ka nako e khutšoanyane e bitsoa tlhaloso e thata. E na le melemo ea tlhahiso e phahameng, bophelo bo bolelele ba li-electrode, le deformation e nyane ea weldment, 'me e loketse litšepe tsa welding tse nang le conductivity e ntle ea mocheso. Tekanyo e fetisang matla a manyane ka nako e telele e bitsoa "soft gauge", e nang le tlhahiso e tlase 'me e loketse litšepe tse chesehang tse atisang ho thatafala.
2. Khatello ea electrode
Nakong ea ho cheselletsa letheba, khatello e etsoang holim'a cheseletso ka electrode e bitsoa khatello ea electrode. Khatello ea electrode e lokela ho khethoa ka nepo. Ha khatello e phahame, ho fokotseha le ho fokotseha ha likoti tse ka 'nang tsa etsahala ha nugget e tiisa e ka felisoa. Leha ho le joalo, ho hanyetsa le sekhahla sa hona joale sa electrode se fokotsehile, se fella ka ho futhumala ho sa lekaneng ha tjheseletsa le ho fokotseha ha bophara ba nugget. Matla a motsoako oa solder a fokotseha. Boholo ba khatello ea electrode bo ka khethoa ho latela lintlha tse latelang:
(1) Thepa ea ho cheselletsa. E phahameng matla a mocheso o phahameng oa thepa. Khatello e kholo ea electrode e hlokahalang. Ka hona, ha ho tjheseletsa tšepe e sa hloekang le tšepe e sa keneleng mocheso, ho lokela ho sebelisoe khatello e phahameng ea eleketrode ho feta ha ho chesetsoa tšepe e tlaase ea carbon.
(2) Mekhahlelo ea ho cheselletsa. Ha mokhoa oa ho tjheseletsa o thatafala, khatello e kholo ea eleketrode.
3. Phaposo
Nakong ea ho cheselletsa letheba, hona joale ho phallang ka ntle ho potoloho e kholo ea tjheseletsa ho bitsoa shunt. The shunt e fokotsa hona joale ho phalla sebakeng sa welding, ho fella ka ho futhumatsa ho sa lekaneng, ho bakang ho fokotseha ho hoholo ha matla a motsoako oa solder le ho ama boleng ba ho tjheseletsa. Mabaka a amang boemo ba phaposo ea phaposo ea molao haholo-holo a kenyelletsa lintlha tse latelang:
(1) Weldment botenya le tjheseletsa sebaka sebaka. Ha sebaka se pakeng tsa manonyeletso a solder se ntse se eketseha, khanyetso ea shunt e eketseha 'me tekanyo ea shunting e fokotseha. Ha sebaka se tloaelehileng sa sebaka sa 30 ho isa ho 50 mm se sebelisoa, shunt ea hona joale e nka 25% ho 40% ea kakaretso ea hona joale, 'me ha botenya ba weldment bo fokotseha, tekanyo ea shunting e boetse e fokotseha.
(2) Boemo ba holim'a tjheseletso. Ha ho e-na le li-oxide kapa litšila holim'a li-weldment, khanyetso ea ho kopana pakeng tsa li-weldments tse peli e eketseha, 'me hona joale ho feta sebakeng sa welding ho fokotseha, ke hore, tekanyo ea shunting e eketseha. Sesebedisoa sa mosebetsi se ka khethoa, sa pentiloe kapa sa hloekisoa.
05. Litlhokomelo tsa polokeho
(1) Sesebelisoa sa leoto sa mochini oa welding se lokela ho ba le sekoaelo se matla sa tšireletso ho thibela ts'ebetso ea kotsi.
(2) Sebaka seo ho sebetsoang ho sona se lokela ho ba le litšepe ho thibela litlhase tse sebetsang hore li se ke tsa fofa.
(3) Litšepe li lokela ho roala likhalase tse sephara tse sireletsang ha li cheseletsa.
(4) Sebaka seo mochine oa ho cheseletsa o behoang ho sona se lokela ho bolokoa se omme, ’me fatše ho lokela ho katoa ka lipoleiti tse thibelang ho tsubella.
(5) Ka mor'a hore mosebetsi oa ho tjheseletsa o phethoe, phepelo ea motlakase e lokela ho khaoloa, 'me sesebelisoa sa metsi a pholileng se lokela ho atolosoa metsotsoana ea 10 pele ho koaloa. Ha mocheso o le tlase, metsi a bokelletsoeng tseleng ea metsi a lokela ho tlosoa ho thibela serame.
