Lintho 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 ka mokhoa o nepahetseng.Ha khatello e phahame, shrinkage porosity le shrinkage cavity e ka 'nang ea etsahala ha nugget e tiisa e ka felisoa, empa ho hanyetsa ha khokahanyo le ho fokotseha ha hona joale ho fokotseha, ho fella ka ho futhumatsa ho lekaneng ha mocheso le ho fokotseha ha bophara ba nugget. motsoako oa solder.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.
