Na ua tseba hore na ke methati e mekae e amehang ts'ebetsong ea welding ea mochini oa welding oa maqhubu a mahareng?Kajeno, mohlophisi o tla u fa selelekela se qaqileng sa ts'ebetso ea welding ea mochini oa tjheseletsa oa maqhubu a mahareng.Kamora ho feta methating ena e 'maloa, ke potoloho ea tjheseletsa ea mochini o tjheseletsang letheba la maqhubu a mahareng.
1. Etsa khatello ea preloading pele matla a ka.
Sepheo sa nako ea preloading ke ho kopana haufi-ufi pakeng tsa likarolo tse cheselitsoeng, ho baka deformation ea polasetiki ea likarolo tse hlaheletseng holim'a sefahleho sa ho kopana, ho senya filimi ea oxide holim'a metsi, le ho hlahisa khanyetso e tsitsitseng ea ho kopana.Haeba khatello e le tlase haholo, ke likarolo tse 'maloa feela tse hlahelletseng tse ka kopanang, tse etsang hore ho be le khanyetso e kholo ea ho kopana.Ho tloha ho sena, tšepe e tla qhibiliha ka potlako sebakeng sa ho kopana, ho phatloha ka mokhoa oa litlhase, 'me maemong a boima, karolo e cheselitsoeng kapa electrode e ka chesoa.Ka lebaka la botenya le boleng bo phahameng ba sebopeho sa likarolo tse cheselitsoeng, boleng ba bokaholimo ba likarolo tse cheselitsoeng bo futsanehile.Ka hona, e le ho etsa hore likarolo tse cheselitsoeng li kopane haufi-ufi le ho tsitsisa khanyetso ea sebaka sa ho tjheseletsa, hona joale ho ka eketsoa nakong ea ho hatella pele kapa nakong ea ho hatella pele.Ka nako ena, khatello ea pele ea khatello hangata ke makhetlo a 0.5-1.5 khatello e tloaelehileng, 'me hona joale ke 1/4-12 ea hona joale ea welding.
2. Ho futhumatsa motlakase.
Ka mor'a ho hatella pele, likarolo tse cheselitsoeng li ka kopanngoa ka thata.Ha litekanyetso tsa tjheseletsa li nepahetse, tšepe e qala ho qhibiliha ka holim'a sefahleho sa ho kopana pakeng tsa likarolo tse peli tse cheselitsoeng sebakeng sa electrode clamping, ntle le ho atolosa, butle-butle ho etsa nucleus e qhibilihisitsoeng.Tlas'a khatello nakong ea welding, nucleus e entsoeng ka ho qhibilihisoa e phatsima (nakong ea welding), e etsa maqhama a matla pakeng tsa likarolo tse peli tse cheselitsoeng.
3. Ho qapa le ho tobetsa.
Mokhahlelo ona o boetse o tsejoa e le sethala sa crystallization e pholileng, ho bolelang hore ka mor'a hore mokokotlo o qhibilihisitsoeng o fihle boemong bo loketseng le boholo, motlakase oa ho tjheseletsa oa khaoloa, 'me motheo o qhibilihisitsoeng oa pholile le ho khanya tlas'a khatello.The molten core crystallization e etsahala ka filimi ea tšepe e koetsoeng 'me e ke ke ea lumellana ka bolokolohi nakong ea crystallization.Ka ho sebelisa mokhoa ona, litšepe tse khabisitsoeng li ka kopanngoa ka thata ntle le ho honyela kapa ho phatloha, ho lumella tšepe e qhibilihisitsoeng hore e khanye ka botlalo pele e emisa tšebeliso.
