01. Tlhaloso e khuts'oane
Spot tjheseletsa ke ho hanyetsa tjheseletsa mokhoa oo tjheseletsa e bokana ka lenonyeletso lap le petelitsoe pakeng tsa li-electrode tse peli, 'me tšepe botlaaseng e qhibiliha ka ho hanyetsa mocheso ho theha lenonyello solder.
Spot welding e sebelisoa haholo-holo likarolong tse latelang:
1. Lenonyeletso la likarolo tsa setempe sa maqephe, joalo ka khebi ea koloi, kariki, mochini o kotulang litlhapi, joalo-joalo.
2. Letlapa le lesesaane le sebopeho sa tšepe sa karolo le sebopeho sa letlalo, joalo ka mabota a mahlakoreng le siling ea likariki, liphanele tsa likoloi tsa tereilara, li-funnels tse kopanyang, joalo-joalo.
3. Li-skrini, liforeimi tsa sebaka le li-cross bar, joalo-joalo.
Thepa ea welding ea Xinfa e na le litšobotsi tsa boleng bo holimo le theko e tlase. Ho fumana lintlha, ka kopo etela:Baetsi ba Welding & Cutting Manufacturers - China Welding & Cutting Factory & Suppliers (xinfatools.com)
03. Ts'ebetso ea ts'ebetso
Bokaholimo ba workpiece bo lokela ho hloekisoa pele ho tjheseletsa. Mokhoa o sebelisoang ka tloaelo oa ho hloekisa ke ho hloekisa, ke hore, ho khetha ka har'a asiti ea sulfuric e futhumetseng ka motsoako oa 10%, ebe o hlatsoa ka metsi a chesang. Ts'ebetso e khethehileng ea welding ke e latelang:
(1) Romela workpiece kopanetsweng pakeng tsa li-electrode ka holimo le ka tlaase tsa letheba tjheseletsa mochine le clamp eona;
(2) motlakase, e le hore libaka tsa ho kopana tsa lisebelisoa tse peli tsa mosebetsi li futhumale 'me li qhibilihe ka mokhoa o itseng ho etsa nugget;
(3) Boloka khatello ka mor'a hore matla a khaotsoe, e le hore nugget e pholile 'me e tiise tlas'a khatello ea ho etsa motsoako oa solder;
(4) Tlosa khatello 'me u ntše workpiece.
04. Lintlha tse susumetsang
Lintlha tse ka sehloohong tse amang boleng ba welding ke nako ea ho tjheseletsa hona joale le ea matla, khatello ea electrode le shunt, joalo-joalo.
1. Welding hona joale le nako ea matla
Ho ea ka boholo ba motlakase oa motlakase le bolelele ba nako ea matla, ho cheselletsa letheba ho ka aroloa ka mefuta e 'meli: tlhaloso e thata le litlhaloso tse 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. E loketse litšepe tsa welding tse nang le conductivity e ntle ea mocheso. Tlhaloso e fetisang motlakase o monyenyane ka nako e telele e bitsoa tlhaloso e bonolo, e nang le tlhahiso e tlaase 'me e loketse litšepe tsa welding tse atisang ho thatafala.
2. Khatello ea electrode
Nakong ea ho cheselletsa letheba, khatello e hlahisoang ke electrode holim'a weldment e bitsoa khatello ea electrode. Khatello ea electrode e lokela ho khethoa hantle. Ha khatello e phahame, e ka felisa shrinkage le shrinkage cavity e ka 'nang ea etsahala ha nugget e tiisa, empa ho hanyetsa ho kopana le ho fokotseha ha hona joale ho fokotseha, ho fella ka ho futhumatsa ho lekaneng ha chese le ho fokotseha ha bophara ba nugget. Matla a motsoako oa solder a fokotsehile. Boholo ba khatello ea electrode bo ka khethoa ho latela lintlha tse latelang:
(1) Thepa ea cheseletso. 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, khatello ea eleketrode e lokela ho ba holimo ho feta ea tšepe e tlase ea carbon.
(2) Mekhahlelo ea ho cheselletsa. Ha tlhaloso ea weld e thatafala, khatello e kholo ea elektrode.
3. sututsa
Nakong ea ho tjheseletsa sebakeng, hona joale ho phalla ho tsoa ka ntle ho potoloho e kholo ea tjheseletsa ho bitsoa shunt. The shunt e fokotsa ho phalla ha hona joale sebakeng sa welding, ho fella ka ho futhumatsa ho sa lekaneng, ho fella ka 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) Botenya ba ho tjheseletsa le ho arohana ha manonyeletso a solder. Ha sebaka se pakeng tsa manonyeletso a solder se ntse se eketseha, khanyetso ea shunt e eketseha 'me tekanyo ea shunt e fokotseha. Ha letheba le tloaelehileng la 30-50mm le amoheloa, shunt ea hona joale e nka 25% -40% ea kakaretso ea hona joale, 'me ha botenya ba ho chesehela bo fokotseha, tekanyo ea shunt e boetse e fokotseha.
(2) Boemo ba bokaholimo ba cheseletso. Ha ho e-na le li-oxides kapa litšila holim'a li-weldment, ho hanyetsa ho kopana pakeng tsa li-weldments tse peli hoa eketseha, 'me hona joale ka sebaka sa welding se fokotseha, ke hore, tekanyo ea shunt e eketseha. Sesebedisoa sa mosebetsi se ka khethoa, sa pentiloe kapa sa hloekisoa.
05. Litlhokomelo tsa Tšireletso
(1) Sesebelisoa sa leoto sa mochini oa welding se lokela ho ba le sekoaelo se tiileng se sireletsang ho thibela ts'ebetso ea kotsi.
(2) Sebaka sa ts'ebetso se tla hlomelloa ka moferefere ho thibela ho phatloha ha litlhase tse sebetsang.
(3) Litšepe li lokela ho roala likhalase tse sephara tse sireletsang ha li cheseletsa.
(4) Sebaka seo mochine oa welding o behoang ho sona se lokela ho bolokoa se omme, 'me fatše ho lokela ho koaheloa ka li-anti-skid boards.
(5) Ka mor'a mosebetsi oa ho tjheseletsa, phepelo ea motlakase e lokela ho khaoha, 'me sesebelisoa sa metsi a pholileng se lokela ho atolosoa ka metsotsoana e 10 pele ho koaloa. Ha mocheso o le tlase, metsi a bokelletsoeng tseleng ea metsi a lokela ho tlosoa ho thibela serame.
