Hona joale, mechine ea ho tjheseletsa laser e tšoaroang ka letsoho e 'nile ea sebelisoa haholo tšimong ea tšepe ea tšepe.Sebakeng se tloaelehileng sa tjheseletsa, 90% ea tjheseletsa ea tšepe e nkeloe sebaka ke ho tjheseletsa ka laser ka lebaka la lebelo la ho tjheseletsa ka laser ho feta ka makhetlo a mahlano ho feta mekhoa e tloaelehileng ea ho tjheseletsa, 'me phello ea ho tjheseletsa e hole ho feta mokhoa o tloaelehileng oa ho tjheseletsa oa arc le welding e sirelelitsoeng.Laser tjheseletsa ka tjheseletsa ea litšepe tse se nang ferrous tse kang motsoako oa aluminium ho na le molemo oa mokhoa oa setso oa ho cheselletsa.Ehlile, mabapi le lisebelisoa tsa tšepe tsa ho tjheseletsa, mechini e ts'oaroang ka letsoho ea laser le eona e na le litemoso tse itseng.
Mohato oa pele ke ho hlahloba hore na shutter reflector e hloekile, kaha lilense tse sa hloekang li ka senyeha nakong ea tšebeliso, e leng se tla qetella se lebisa ho hlōleha ho ke keng ha lokisoa.Ha laser e se e loketse ho tsamaea kamora ho hlophisoa ha eona ka botlalo.Ka nts'etsopele ea theknoloji ea welding ea laser, theknoloji ea welding ea laser e ntse e hola 'me e se e sebelisoa mefuteng e fapaneng ea liindasteri.Leha ho le joalo, ts'ebetsong ea tlhahiso le ts'ebeliso ea letsatsi le letsatsi, ka lebaka la mabaka a fapaneng, ho ntse ho tla ba le litaba tse itseng.Ka hona, ho laola le ho rarolla mathata ana a amang katleho ea mosebetsi ke eona ntho e tlang pele.Hangata, re fumana sesosa sa bothata ka ho sebelisa liketsahalo le ho laola mefuta-futa.
Ka kakaretso, ho na le mabaka a mabeli a ho se sebetse hantle:
1. Haeba ho na le bothata ba ho sebetsana le boitsebiso boo, boitsebiso bo fosahetseng bo lokela ho nkeloa sebaka ho finyella sephetho se lakatsehang.
2. Litlhophiso tsa litekanyetso tsa tekheniki li hloka tlhahlobo e tsoelang pele ea likarolo tse tšoanang ho ea ka sehlahisoa se cheselitsoeng le lipuisano tse thehiloeng ho liphello tsa teko.
Ntle le moo, welding ea laser e na le melemo e mengata eo welding ea setso e ke keng ea e bapisa:
1. Tšireletseho.Toche nozzle tla feela qala ho sebetsa ha e kopana le tšepe, ho fokotsa kotsi ea misoperation, 'me ho ama switjha ya tjheseletsa toche hangata e na le mocheso lemoha tshebetso, e leng tla ka tsela e iketsang khaotsa ho sebetsa ha ho feta-chesa.
2. Ho tjheseletsa ka angle efe kapa efe ho ka finyelloa.Laser welding ha e sebetse hantle feela bakeng sa li-welds tse tloaelehileng, empa hape e na le maemo a holimo haholo le ts'ebetso ea welding ho li-welds tse rarahaneng, li-workpieces tse kholo, le li-welds tse sa bopehileng hantle.
3. Laser tjheseletsa ka thusa ho boloka sebaka se hloekileng ho sebetsa fekthering.Laser welding e na le spatter e fokolang le phello e tsitsitseng ea welding, e ka fokotsang haholo tšilafalo ka har'a fektheri le ho netefatsa tikoloho e hloekileng ea ho sebetsa.
Leha ho le joalo, laser welding e boetse e na le litlhoko tse itseng ts'ebetsong ea 'nete ea kopo, joalo ka ho amohela moralo o mosa haholoanyane bakeng sa lisebelisoa tsa welding tsa laser, le ho ntlafatsa le ho ntlafatsa ts'ebetso ea tlhahiso ea lakane ea tšepe.Laser welding e boetse e na le litlhoko tse phahameng haholo bakeng sa ho sebetsa ka ho nepahala le boleng ba sebopeho.Haeba u batla ho fana ka papali e feletseng ho melemo ea laser welding, ho fokotsa litšenyehelo le ho ntlafatsa katleho, hoa hlokahala ho ntlafatsa ts'ebetso ea tlhahiso ea tšepe ea lakane kapa litšepe tse ling tlhahiso ea sebele.Joalo ka moralo oa sehlahisoa, ho itšeha ka laser, ho hatakela, ho kobeha, ho tjheseletsa laser, joalo-joalo, ho ntlafatsa mokhoa oa ho tjheseletsa ho tjheseletsa laser, ho ka fokotsa litšenyehelo tsa tlhahiso ea feme ka hoo e ka bang 30%, 'me welding ea laser e fetohile khetho ea likhoebo tse ngata.
Mathata a aluminium alloy laser welding:
1. Aluminium alloy e na le litšobotsi tse bobebe, tse seng tsa makenete, tse fokolang mocheso, ho hanyetsa kutu, ho etsa bonolo, joalo-joalo, kahoo e sebelisoa haholo tšimong ea welding.Ho sebelisa motsoako oa aluminium sebakeng sa tšepe ea tšepe ho ka fokotsa boima ba sebopeho ka 50%.
2. Aluminium alloy welding e bonolo ho hlahisa li-pores.
3. The linear katoloso coefficient ea aluminium alloy weld e kholo, e leng monyetla oa ho baka deformation nakong ea welding.
4. Ho atolosoa ha mocheso ho tloaelehile ho etsahala nakong ea aluminium alloy welding, e leng se bakang mapetsong a mocheso.
5. Litšitiso tse kholo ka ho fetisisa tsa ho tuma le ho sebelisoa ha motsoako oa aluminium ke ho nolofatsa ho tebileng ha manonyeletso a nang le li-welded le coefficient e tlaase ea matla.
6. Bokaholimo ba motsoako oa aluminium ho bonolo ho etsa filimi ea oxide e refractory (sebaka sa ho qhibiliha sa A12O3 ke 2060 ° C), se hlokang ts'ebetso ea ho cheselletsa matla a matla.
7. Aluminium alloy e na le conductivity e phahameng ea mocheso (hoo e ka bang makhetlo a 4 a tšepe), 'me tlas'a lebelo le tšoanang la ho tjheseletsa, mocheso oa mocheso ke makhetlo a 2 ho isa ho a 4 a tšepe e cheselitsoeng hape.Ka hona, aluminium alloy welding e hloka matla a mangata a matla, ho kenya mocheso o tlase oa welding le lebelo le phahameng la tjheseletsa.
