Revolution of Technology Welding |Laser Welding for Aluminiyam Alloy
Iialloyi zeAluminiyam zisetyenziswa ngokubanzi kwiimveliso ezidityanisiweyo ezidityanisiweyo ngenxa yobunzima bazo, amandla aphezulu, ukuchasana nokugqwala okuhle, iipropathi ezingezizo-magnetic, ukumila kakuhle kunye nokusebenza kakuhle kobushushu obuphantsi.Xa i-welding nge-alloys ye-aluminium, ubunzima bemveliso yesakhiwo esidibeneyo sinokuncitshiswa ngama-50% xa kuthelekiswa nezo zifakwe kwiipleyiti zetsimbi.Okwangoku, oku kusetyenziswe ngokubanzi kumashishini ahlukeneyo afana neenqwelomoya, i-aerospace, imoto, ibhetri yamandla, ukuveliswa koomatshini, ukwakhiwa kweenqanawa, iingcango kunye neefestile, ishishini lemichiza kunye neemfuno zemihla ngemihla.
Itekhnoloji ye-laser ye-welding ephezulu ye-aluminium alloy
Itekhnoloji ye-laser welding ye-aluminium alloy yitekhnoloji entsha ephuhliswe kule minyaka ilishumi idlulileyo.Ibonisa ukusebenza okuqinileyo, ukuthembeka okuphezulu kunye nokusebenza kakuhle okuphezulu xa kuthelekiswa nendlela ye-welding yendabuko.Nazi izibonelelo ze-laser welded aluminium alloys:
▪ Uxinaniso lwamandla aphezulu, igalelo lobushushu eliphantsi, ukuguquka kobushushu obuphantsi, indawo emxinwa yokunyibilika kunye nendawo echatshazelwe bubushushu kunye nobunzulu obukhulu bokunyibilika.
▪ Ubume be-Microfine weld ngenxa yezinga eliphezulu lokupholisa kunye nokusebenza kakuhle ngokubambisana.
▪ I-laser welding ngaphandle kwee-electrode, ukunciphisa iiyure zabantu kunye neendleko.
▪ Ubume bomsebenzi odityanisiweyo awuchatshazelwa nguzibuthe wombane kwaye awuvelisi imitha yeX-reyi.
▪ Ukukwazi ukuwelda imathiriyeli yesinyithi ngaphakathi kwezinto ezivaliweyo ezicacileyo.
▪ Ilaser inokudluliselwa kumgama omde ngeoptical fibers, ebangela ukuba inkqubo ilungelelane.Ngeekhompyuter kunye neerobhothi, inkqubo ye-welding inokuzenzekela kwaye ilawulwe ngokuchanekileyo.
Izinto ezilungileyo zokujongana ne-alloys ye-aluminiyam ephethwe ngubushushu
Yandisa isantya sokuqhubekeka
Ukwandisa ukusebenza kwemveliso kunye nokuphucula umgangatho we-welding ngokunciphisa kakhulu igalelo lobushushu.
Xa welding high-amandla kunye nobukhulu-ubukhulu-aluminiyam ialloyi, inokufikelela ngokulula ukuwelda ngokusebenzisa kwi pass enye ngokwenza ubunzulu enkulu isitshixo apho welding laser nzulu fusion kunye nesiphumo keyhole kwenzeka, oko kunamandla kuneendlela welding zemveli.
Ukuthelekisa umthombo we-laser oqhelekileyo kwi-laser welding ye-aluminium alloys
Kule mihla, imithombo yelaser ephambili esetyenziswa kwimarike yiCO2 laser, YAG laser kunye nefiber laser.Ngenxa yokusebenza kwamandla aphezulu, i-CO2 laser ifaneleke ngakumbi ukuwelda ipleyiti eshinyeneyo, kodwa izinga lokufunxa kwe-CO2 laser beam kumphezulu we-aluminium alloy lincinci, elibangela ukulahleka kwamandla amaninzi ngexesha lenkqubo ye-welding.
I-laser ye-YAG ngokubanzi incinci ngamandla, inqanaba lokufunxa kwe-YAG laser beam kumphezulu we-aluminium alloy inkulu kune-CO2 laser, i-optical fiber conduction ekhoyo, ukuguquguquka okuqinileyo, ulungiselelo lwenkqubo elula, njl., ukusilela kwe-YAG: i amandla okuphuma kunye namandla okuguqula umbane aphantsi.
I-Fiber laser ineenzuzo zobukhulu obuncinci, iindleko eziphantsi zokusebenza, ubomi benkonzo ende, ukuzinza okulungileyo kunye nomgangatho ophezulu we-beam.Okwangoku, ukukhanya okukhutshwa yi-fiber laser yi-1070nm wavelength enezinga eliphezulu lokufunxa, izinga lokuguqulwa kweefoto zombane liphindwe kali-10 kune-LAG laser, kwaye isantya se-welding sikhawuleza kune-YAG kunye ne-CO2 laser.
Welding Technology Revolution
Kulindeleke ukuba kufakwe izixhobo zokuwelda i-laser kwi-aluminium alloy welding
Njengenkqubo ye-welding-energy-density welding, i-laser welding inokuthintela ngokufanelekileyo iziphene ezibangelwa yinkqubo ye-welding yendabuko, kwaye i-coefficient yamandla e-welding nayo iya kuphuculwa kakhulu.Kusenzima ukusebenzisa umatshini wokuwelda wamandla aphantsi we-laser ukuwelda iipleyiti ezishinyeneyo ze-aluminium, kungekuphela nje ngenxa yokuba inqanaba lokufunxa lelaser kumphezulu we-aluminium alloy liphantsi kakhulu, kodwa kusekho ingxaki yomqobo ekhoyo xa ifuna. i-welding yokungena enzulu.
Olona phawu lutsala amehlo kumatshini wokuwelda i-aluminiyam i-alloy laser welding kukusebenza kwawo okuphezulu, okusetyenziswa kwi-welding enkulu-enzulu yokungena ukuze isetyenziswe.Kwaye le teknoloji ye-welding ye-welding enkulu-ubukhulu obukhulu iya kuba luphuhliso olungenakuthintelwa kwixesha elizayo.Ngenye indlela, le welding yokungena enzulu ibalaselisa isiganeko se-pinhole kunye nefuthe layo kwi-weld porosity, eyenza indlela yokwakheka kwepinhole kunye nolawulo lwayo lubaluleke ngakumbi, kwaye ngokuqinisekileyo iya kuba lutshintsho kwihlabathi lokuwelda kwixesha elizayo.
