Litšitiso tse Tloaelehileng ho Welding ea Laser le Mokhoa oa ho li Rarolla

Laser welding ke mokhoa o sebetsang hantle haholo le o nepahetseng o sebelisoang liindastering tse fapaneng. Leha ho le joalo, liphoso tse ling tse kang mapetsong, porosity, spatter, burn-through, le undercutting li ka etsahala nakong ea ts'ebetso. Ho utloisisa lisosa tsa liphoso tsena le tharollo ea tsona ke senotlolo sa ho ntlafatsa boleng ba welding le ho netefatsa liphetho tse tšoarellang nako e telele. Ka tlase ke liphoso tse kholo tse fumanoang ho welding laser le mokhoa oa ho li rarolla:

1. Mapetso

Lebaka: Hangata mapetsong a hlaha ka lebaka la matla a ho honyela ho feteletseng pele letamo la weld le tiea ka botlalo. Hangata li amahanngoa le mapetsong a chesang, a kang ho tiisa kapa ho phunyeha ha metsi.

Tharollo: Ho fokotsa kapa ho felisa mapetsong, ho futhumatsa mosebetsi oa pele le ho eketsa lisebelisoa tsa ho tlatsa ho ka thusa ho aba mocheso ka mokhoa o ts'oanang, kahoo ho fokotsa khatello ea kelello le ho thibela mapetsong.

2. Porosity

Lebaka: Ho tjheseletsa ka laser ho etsa letamo le tebileng, le moqotetsane la weld le pholileng ka potlako. Likhase tse hlahisoang ka letamong le entsoeng ka ho qhibilihisoa ha li na nako e lekaneng ea ho baleha, e lebisang ho thehoeng ha lipokothong tsa khase (pores) ho cheselletsa.

Tharollo: Ho fokotsa porosity, hloekisa bokaholimo ba mosebetsi hantle pele u tjheseletsa. Ho phaella moo, ho fetola tsela ea khase e sireletsang ho ka thusa ho laola phallo ea khase le ho fokotsa monyetla oa ho thehoa ha pore.

3. Spatter

Lebaka: Spatter e amana ka ho toba le matla a matla. Ha matla a motlakase a le holimo haholo, thepa e fetoha mouoane haholo, e leng se etsang hore ho phatloha ha lintho tse entsoeng ka ho qhibilihisoa ho fofe ka ntle ho letamo la weld.

Tharollo: Fokotsa matla a tjheseletsa mme o lokise lebelo la welding ho boemo bo loketseng. Sena se tla thusa ho thibela mouoane o feteletseng oa thepa le ho fokotsa ho hasana.

4. Ho chesoa

Lebaka: Sekoli sena se etsahala ha lebelo la tjheseletsa le potlakile haholo, ho etsa hore tshepe e metsi e hlolehe ho abuwa hantle. E ka boela ea etsahala ha lekhalo le kopane le le leholo haholo, le fokotsa palo ea tšepe e qhibilihisitsoeng e fumanehang bakeng sa ho kopanya.

Tharollo: Ka ho laola matla le lebelo la welding ka kutloano, ho chesa ho ka thibeloa, ho etsa bonnete ba hore letamo la weld le laoloa ka mokhoa o lekaneng bakeng sa ho kopanya hantle.

5. Undercuting

Lebaka: Undercutting e etsahala ha lebelo la welding le lieha haholo, ho fella ka letamo le leholo, le pharaletseng la weld. Bophahamo bo ntseng bo eketseha ba tšepe e qhibilihisitsoeng bo etsa hore ho be thata bakeng sa tsitsipano ea holim'a metsi ho tšoara tšepe e metsi sebakeng, e etsa hore e thekesele.

Tharollo: Ho theola boima ba matla ho ka thusa ho qoba ho fokotseha, ho etsa bonnete ba hore letamo le qhibilihisitsoeng le boloka sebopeho le matla a lona nakong eohle ea ts'ebetso.

Karolo ea Li-Chillers tsa Metsi ka Laser Welding

Ntle le litharollo tse kaholimo, ho boloka mocheso o nepahetseng oa ho sebetsa oa laser welder ho bohlokoa ho thibela liphoso tsena. Mona ke moo li-chillers tsa metsi li kenang teng. Ho sebelisa chiller ea metsi nakong ea ts'ebetso ea welding ea laser ho bohlokoa hobane ho thusa ho boloka mocheso o tsitsitseng ho laser le workpieces. Ka ho laola mocheso ka katleho sebakeng sa tjheseletsa, li-chillers tsa metsi li fokotsa sebaka se amehileng ke mocheso le ho sireletsa likarolo tsa optical tse nang le kutloelo-bohloko ho senya mocheso. Sena se tiisa botsitso le boleng ba lebone la laser, qetellong se ntlafatsa boleng ba tjheseletsa le ho fokotsa menyetla ea likoli tse kang mapetsong le porosity. Ho feta moo, li-chillers tsa metsi li lelefatsa bophelo ba lisebelisoa tsa hau ka ho thibela mocheso o feteletseng le ho fana ka ts'ebetso e tšepahalang, e tsitsitseng.

Qetello: Ka ho utloisisa lisosa tsa metso ea liphoso tse tloaelehileng tsa welding laser le ho kenya ts'ebetsong litharollo tse sebetsang, tse kang ho futhumatsa, ho fetola matla le litlhophiso tsa lebelo, le ho sebelisa li-chillers, u ka ntlafatsa haholo boleng ba tjheseletsa. Mehato ena e netefatsa lihlahisoa tsa boleng bo holimo, tse khahlehang, le tse tšoarellang, ha e ntse e ntlafatsa ts'ebetso le nako ea bophelo ea lisebelisoa tsa hau tsa laser welding.

Bakeng sa tlhaiso-leseling e batsi mabapi le mokhoa oa ho ntlafatsa ts'ebetso ea hau ea welding ea laser ka litharollo tse tsoetseng pele tsa ho pholisa, ikutloe u lokolohile ho ikopanya le rona.
