Morero oa ho futhumatsa pele ho Mechini ea Aluminium Rod Butt Welding

Aluminium rod butt welding ke ts'ebetso e sebelisoang haholo lits'ebetsong tse fapaneng tsa indasteri, e tsejoang ka bokhoni ba eona ba ho theha li-welds tse matla le tse tšoarellang. Karolo e 'ngoe ea bohlokoa ea ts'ebetso ena ke ho futhumatsa pele, ho kenyelletsang ho phahamisa mocheso oa lithupa tsa aluminiamo pele li ts'oaroa hammoho. Sehloohong sena, re tla hlahloba bohlokoa le melemo ea ho futhumatsa pele mochining oa aluminium rod butt welding.

Mochini oa ho tjheseletsa butt

1. Phokotso ea Khatello

Preheating e bapala karolo ea bohlokoa ho fokotsa khatello ea maikutlo e ka bang teng nakong ea ts'ebetso ea welding. Aluminium, joalo ka litšepe tse ling tse ngata, e na le tšekamelo ea ho hola le ho hola ha e futhumatsoa ebile e pholile. Ha lithupa tsa aluminium li futhumatsoa ka potlako le ho chesetsoa ntle le ho futhumatsa pele, ho ka ba le phapang e kholo ea mocheso ka har'a thepa. Ho futhumala hona ka potlako le ho pholile ho ka lebisa ho thehoeng ha likhatello tsa ka hare, tse ka fokolisang weld le lintho tse potolohileng.

Ka ho futhumatsa melamu ea aluminium esale pele, phapang ena ea mocheso e fokotsehile. Ts'ebetso ea ho futhumatsa butle-butle e lumella ho fana ka mocheso o ts'oanang haholoanyane ho pholletsa le thepa. Ka lebaka leo, motsoako oa weld le libaka tse potolohileng phihlelo e fokotsehile khatello ea kelello, e lebisang ho chese e matla le e ka tšeptjoang haholoanyane.

2. Thibelo ea Crack

Aluminium e ka pepeseha habonolo nakong ea ts'ebetso ea welding, haholo ha mocheso o fetoha ka tšohanyetso. Ho futhumatsa ho thusa ho thibela ho thehoa ha mapetsong ka ho etsa bonnete ba hore mocheso o laoloang le butle-butle o phahama le ho oa. Li-cracks li ka senya botšepehi ba weld le ho fokotsa matla a eona, ho etsa hore preheating e be mohato oa bohlokoa oa ho qoba liphoso tsa weld.

3. Sebetsa se Ntlafetseng

Mechini ea ho cheselletsa melamu ea aluminium hangata e sebetsa ka limaraka tse fapaneng le botenya ba melamu ea aluminium. Preheating e ka ntlafatsa ts'ebeliso ea lisebelisoa tsena tse fapaneng ka ho ntlafatsa maemo a ts'ebetso ea welding. E lumella aluminium hore e fihle boemong ba mocheso moo e amohelang mocheso oa welding, e leng se etsang hore ho be le fusion e ntlafetseng pakeng tsa melamu.

4. Porosity e Fokotseng

Ho futhumatsa ho ka boela ha thusa ho fokotsa ho thehoa ha lipokotho tsa khase kapa li-voids ka har'a weld, tse tsejoang e le porosity. Ha aluminium e futhumatsoa ka potlako, likhase leha e le life tse koaletsoeng, tse kang hydrogen kapa oksijene, li ka 'na tsa tsoa ho thepa, tsa baka likheo ka har'a weld. Li-voids tsena li ka fokolisa weld mme tsa senya boleng ba eona. Preheating e fokotsa menyetla ea ho kenngoa ha khase 'me e khothalletsa hore ho be le seaparo se tšoanang, se tiileng.

5. Matla a Manonyeletso a Matlafalitsoeng

Qetellong, sepheo sa mantlha sa ho futhumatsa pele ka aluminium rod butt welding ke ho hlahisa litšepe tse matla, tse tšepahalang. Ka ho fokotsa khatello ea maikutlo, ho thibela mapetsong, ho ntlafatsa weldability, le ho fokotsa porosity, preheating e kenya letsoho ho thehoeng ha manonyeletso a weld a nang le thepa e phahameng ea mochine. Manonyeletso ana a bonts'a matla a eketsehileng, ductility, le ho hanyetsa ho hloleha, ho netefatsa hore a fihlela litlhoko tse thata tsa lits'ebetso tse fapaneng tsa indasteri.

Qetellong, ho futhumatsa ka mochini oa aluminium rod butt welding ke mohato oa bohlokoa o susumetsang haholo boleng le ts'ebetso ea li-welds tse hlahisoang. E thusa ho fokotsa khatello ea maikutlo, ho thibela mapetsong, ho matlafatsa weldability, ho fokotsa porosity, 'me qetellong ho ntlafatsa matla a manonyeletso. Ho kenyelletsa preheating ts'ebetsong ea welding ho bohlokoa bakeng sa ho fihlela litšepe tse tšoarellang le tse ka tšeptjoang tsa aluminium, e leng se etsang hore e be mokhoa oa bohlokoa maemong a mangata a indasteri.
