Mechini ea ho tjheseletsa ha aluminium rod butt e tumme ka bokhoni ba eona ba ho etsa litšepe tse matla le tse tšepahalang. Leha ho le joalo, taba e 'ngoe e tloaelehileng e ka amang boleng ba li-welds tsena ke ho ba mosehla ha libaka tsa welding. Bosehla bona, hangata bo bakoang ke oxidation, bo ka senya botšepehi ba li-welds. Sehloohong sena, re tla hlahloba mekhoa ea ho rarolla le ho thibela ho ba mosehla ha libaka tsa welding mochining oa aluminium rod butt.
1. Tokisetso e Nepahetseng ea Lintho
Ho thibela mosehla ho qala ka ho lokisetsa thepa e nepahetseng. Netefatsa hore lithupa tsa aluminium tse lokelang ho chesetsoa li hloekile ebile ha li na litšila tse kang litšila, mafura, kapa oxidation. Hloekisa bokaholimo ba lithupa ka ho sebelisa mekhoa e nepahetseng ea ho hloekisa, joalo ka borashe kapa ho hloekisa ka lik'hemik'hale, ho tlosa litšila tse ka lebisang ho senyeheng.
2. Sepakapaka se Laoloang
Tsela e 'ngoe e atlehang ea ho thibela ho ba mosehla nakong ea ho cheselletsa ke ho etsa hore ho be le moea o laoloang ho potoloha sebaka sa ho cheselletsa. Sena se ka finyelloa ka ho sebelisa khase ea inert, e kang argon, ho sireletsa libaka tsa welding ho tloha oksijene ea sepakapaka. Tšireletso ea khase e sa sebetseng e thibela oxidation mme e thusa ho boloka 'mala oa tlhaho oa aluminium.
3. Ho futhumatsa pele
Ho futhumatsa melamu ea aluminium pele ho tjheseletsa le hona ho ka thusa ho fokotsa mosehla. Ka ho eketsa butle-butle mocheso oa li-rods, preheating e fokotsa ho ata ka potlako le ho fokotseha ho ka lebisang ho oxidation ea holim'a metsi. E khothalletsa ts'ebetso ea welding e bonolo, e fokotsang monyetla oa ho ba mosehla.
4. Mekhahlelo e nepahetseng ea Welding
Mekhahlelo ea tjheseletsa, ho kenyeletsoa hona joale, khatello, le nako ea ho cheselletsa, e phetha karolo ea bohlokoa ho thibela mosehla. Ho sebelisa li-parameter tse nepahetseng bakeng sa lithupa tse khethehileng tsa aluminium tse cheselitsoeng ho tiisa kabo e nepahetseng ea mocheso le ho fokotsa kotsi ea oxidation. Sheba likhothaletso tsa moetsi bakeng sa liparamente tse loketseng tsa welding.
5. Ho Hloekisa ka mor'a Weld le Phekolo
Ka mor'a ho cheselletsa, ho bohlokoa ho hloekisa le ho tšoara libaka tsa weld hang-hang. Tlosa phallo efe kapa efe e setseng kapa litšila u sebelisa mekhoa e loketseng ea ho hloekisa. Joale, nahana ka ho sebelisa phekolo ea post-weld, e kang aluminium e khethehileng ea ho hloekisa tharollo kapa seaparo se sireletsang, ho thibela oxidation e eketsehileng le mosehla.
6. Mehato ea Tšireletso
Kenya ts'ebetso ea ts'ireletso ho sireletsa libaka tsa welding moeeng o ka hare nakong ea ts'ebetso ea welding. Sena se ka kenyelletsa tšebeliso ea likharetene tsa welding kapa lithebe ho theha tšitiso e fokotsang ho pepesehela oksijene. Ho boloka sebaka sa welding se se na li-drafts le hona ho ka thusa ho boloka tikoloho e tsitsitseng ea welding.
7. Tlhokomelo ea Nako le Nako
Kamehla hlahloba le ho boloka mochine oa welding, ho kenyelletsa le li-electrode le likarolo tsa hlooho ea welding. Ho roala leha e le hofe kapa ho senyeha ha likarolo tsena ho ka lebisa ho tjheseletsa ho sa tsitsang le ho eketseha ha oxidation. Ho rarolla mathata ana hang-hang ho ka thusa ho thibela yellowing.
Qetellong, ho sebetsana le ho thibela le ho thibela mosehla oa libaka tsa ho tjheseletsa ka mochini oa aluminium rod butt welding o hloka motsoako oa ho lokisoa ha lintho tse nepahetseng, moea o laoloang, ho futhumatsa pele, le ho khomarela litekanyetso tse nepahetseng tsa welding. Ho phaella moo, ho hloekisa le ho phekola ka mor'a ho chesehela, hammoho le mehato ea tšireletso le tlhokomelo ea kamehla, ke mehato ea bohlokoa ho boloka botšepehi le ponahalo ea li-welds. Ka ho latela litloaelo tsena, u ka etsa bonnete ba hore ts'ebetso ea hau ea aluminium rod butt ea ho hlahisa litšepe tsa boleng bo holimo tse nang le 'mala o fokolang.
