Melemo ea mochini oa welding oa laser ke ofe?

Mochini oa tjheseletsa oa lasere 'nile ea etsoa lipatlisiso ho tloha ha ho tsoaloa li-laser ka bo-1960.E bile le phihlelo ea lilemo tse ka bang 40 tsa tsoelo-pele ho tloha ho tjheseletsa ha likaroloana tse nyenyane tse nyenyane kapa lisebelisoa ho ea ts'ebetsong ea hona joale e kholo ea matla a phahameng a laser welding tlhahiso ea indasteri.E ile ea ithutoa ka ho hlaka qalong ea lekholo la bo20 la lilemo.Laser ea pele e entsoe ka 1960. Lilemo tse 'ne hamorao, laser ea pele ea YAG solid-state le laser ea khase ea CO2 e ile ea hlahisoa.Ho tloha ka nako eo, mechini ea welding ea laser e 'nile ea sebelisoa haholo mefuta e fapaneng ea liindasteri.

1.Melemo eamochine oa ho tjheseletsa laserha e bapisoa le mekhoa ea khale ea ho cheselletsa

① Pele ho qaleha ha laser welding, indasteri ea liindasteri esale e sebelisa mekhoa ea khale ea ho cheselletsa.Ka lebaka la mocheso o sa lekaneng oa sebakeng seo le ho pholisa ha tjheseletsa, hangata ho etsahala ka mor'a ho chesehela deformation, kahoo ho hlōleha ho finyella litlhoko tsa ho tjheseletsa, 'me hobane ho cheselletsa ha hoa lekana ka ho lekaneng, ho tla boela ho be le fusion e sa fellang pakeng tsa workpiece le tšepe ea weld kapa. the weld layer, le weld e na le slag e seng metallic, e monyang khase le ho hlahisa li-pores le liphoso tse ling, tse atisang ho etsa hore likarolo tse cheselitsoeng li phatlohe le ho ama ts'ebetso ea ho tiisa.

② Laser welding e na le melemo ea matla a mangata a matla, deformation e nyane, sebaka se tšesaane se anngoeng ke mocheso, lebelo le phahameng la welding, taolo e bonolo ea othomathike, 'me ha ho na ts'ebetso ea morao-rao.Lilemong tsa morao tjena, e fetohile mokhoa oa bohlokoa oa ho sebetsa le ho etsa thepa ea tšepe.E sebelisoa haholo likoloing, sefofaneng, indastering ea ts'ireletso, kaho ea likepe, boenjiniere ba likepe, lisebelisoa tsa matla a nyutlelie le masimong a mang, lisebelisoa tse amehang li koahela hoo e batlang e le lisebelisoa tsohle tsa tšepe.

③ Leha ho bapisoa le mekhoa ea khale ea ho tjheseletsa, laser welding e ntse e na le mathata a lisebelisoa tse theko e boima, matsete a maholo a nako e le 'ngoe le litlhoko tse phahameng tsa tekheniki, e leng se etsang hore ts'ebeliso ea indasteri ea welding ea laser naheng ea heso e fokotsehe, empa laser welding e na le ts'ebetso e phahameng ea tlhahiso. ho bonolo ho elelloa likarolo tse laoloang ka boiketsetso li etsa hore e be e loketseng mela ea tlhahiso ea bongata le tlhahiso e feto-fetohang.

④ Hajoale, welding ea tšepe e na le litlhoko tse holimo le tse holimo bakeng sa matla le ponahalo.Mokhoa o tloaelehileng oa tjheseletsa o tla baka mathata a kang ho sotha le deformation ea workpiece ka lebaka la ho kenya letsoho mocheso o moholo.E le ho lokisa bothata ba deformation, palo e kholo ea mehato ea ho latela e hlokahalang, e leng se etsang hore ho be le keketseho ea litšenyehelo.Mokhoa o ikemetseng oa laser welding o na le karolo e nyane ka ho fetisisa ea mocheso le sebaka se senyenyane haholo se amehileng ke mocheso, se ntlafatsang haholo boleng ba sesebediswa se cheselitsoeng, se fokotsa litšenyehelo tsa ts'ebetso, 'me se ntlafatsa haholo ts'ebetso ea tjheseletsa le botsitso.

2.Different mehlala, mefuta e fapaneng ya dikgetho

Ka kakaretso, theknoloji ea morao-rao ea welding ea laser e hōlile haholo.Mechini ea tjheseletsa ea laserho ba le tšebeliso e tlase ea matla, ho nepahala ho phahameng, le tšilafalo e fokolang ea tikoloho.Liindasteri tse ntseng li eketseha tsa thekenoloji li ntse li khetha mechini ea welding ea laser ho netefatsa boleng ba sehlahisoa le ho tiisetsa lik'hamphani le bareki.
