Okungakumbi malunga netekhnoloji yokuwelda nge-laser

Itekhnoloji yokudibanisa i-laser, okanye itekhnoloji yokudibanisa i-laser, isebenzisa umqadi we-laser onamandla aphezulu ukugxila nokulawula ukukhanya komphezulu wezinto, kwaye umphezulu wezinto ufunxa amandla e-laser kwaye uwuguqule ube ngamandla obushushu, nto leyo ebangela ukuba izinto zifudumale kwaye zinyibilike kwindawo ethile, kulandele ukupholisa kunye nokuqina ukuze kufezekiswe ukuhlanganiswa kwezinto ezifanayo okanye ezahlukileyo. Inkqubo yokudibanisa i-laser ifuna uxinano lwamandla e-laser lwe-10⁴ukuya kwi-10⁸W/cm²Xa kuthelekiswa neendlela zemveli zokuwelda, ukuwelda nge-laser kunezi nzuzo zilandelayo.

Ilifu leplasma eli-1, izinto ezinyibilikisayo ezi-2, umngxuma wezitshixo ezi-3, ubunzulu obu-4 bokudibanisa
 
Ngenxa yokubakho komngxuma wesitshixo, umqadi welaser, emva kokukhanyisa ngaphakathi komngxuma wesitshixo, uya kwandisa ukufunxwa kwelaser zizinto kwaye ukhuthaze ukwakheka kwechibi elinyibilikisiweyo emva kokusasazeka kunye nezinye iziphumo, iindlela ezimbini zokuwelda zithelekiswa ngolu hlobo lulandelayo.
 


Lo mfanekiso ungentla unika inkqubo yokuwelda nge-laser yezinto ezifanayo kunye nomthombo wokukhanya ofanayo, indlela yokuguqula amandla yenziwa kuphela nge-keyhole, i-keyhole kunye nesinyithi esinyibilikisiweyo kufutshane nodonga lomngxuma zihamba ngokuhambela phambili kwe-laser beam, isinyithi esinyibilikisiweyo sisusa isitshixo emoyeni oshiyekileyo ukuze sizalise kwaye emva kokufuma, senza umthungo we-weld.
 
Ukuba izinto eziza kudityaniswa zizinto zesinyithi ezahlukileyo, ukubakho komahluko kwiipropati zobushushu kuya kuba nefuthe elikhulu kwinkqubo yokudibanisa, njengomahluko kwiindawo zokunyibilika, ukuqhuba kobushushu, umthamo othile wobushushu, kunye nee-coefficients zokwandiswa kwezinto ezahlukeneyo, okubangela uxinzelelo lokudibanisa, ukuguqulwa kokudibanisa, kunye notshintsho kwiimeko zekristale zentsimbi edibeneyo edibeneyo, okubangela ukwehla kweempawu zoomatshini ze-weld.
 
Ngoko ke, ngokweempawu ezahlukeneyo zendawo yokuwelda, inkqubo yokuwelda iphuhlise ukuwelda kwe-laser filler, i-laser brazing, i-laser welding enemiqadi emibini, i-laser composite welding, njl.

Ukuwelda kwe-Laser Wire Filling
Kwinkqubo yokuwelda nge-laser ye-aluminium, i-titanium kunye ne-copper alloys, ngenxa yokufunxwa okuncinci kokukhanya kwe-laser (<10%) kwezi zinto, i-plasma eveliswa yifoto inokhuselo oluthile lokukhanya kwe-laser, ngoko ke kulula ukwenza i-spatter kwaye ikhokelele ekudalweni kweziphene ezifana ne-porosity kunye ne-cracks. Ukongeza, umgangatho we-welding uyachaphazeleka xa umsantsa phakathi kwezinto zokusebenza umkhulu kunobubanzi be-spot ngexesha lokutshiza i-plate encinci.
 
Ekusombululeni ezi ngxaki zingasentla, iziphumo ezingcono zokuwelda zingafumaneka ngokusebenzisa indlela yezinto zokuzalisa. Isizalisi singaba yingcingo okanye umgubo, okanye indlela yokuzalisa esele isetiwe ingasetyenziswa. Ngenxa yendawo encinci egxile kuyo, isizalisi siba sincinci kwaye sibe nemilo engqukuva kancinci kumphezulu emva kokuba izinto zokuzalisa zisetyenzisiwe.

Ukugquma ngeLaser
Ngokungafaniyo ne-fusion welding, enyibilikisa iindawo ezimbini ezidityanisiweyo ngaxeshanye, i-brazing yongeza into yokuzalisa ene-melting point ephantsi kune-base material kumphezulu we-weld, inyibilikisa into yokuzalisa ukuze izalise isithuba kubushushu obuphantsi kune-melting point ye-base material kwaye ingaphezulu kune-melting point ye-filler material, ize emva koko ijike ibe yi-solid weld.
 
I-Brazing ifanelekile kwizixhobo ze-microelectronic ezibuthathaka kubushushu, iipleyiti ezincinci, kunye nezinto zesinyithi eziguquguqukayo.
 
Ngaphezu koko, ingahlulwahlulwa ngakumbi njenge-soft brazing (<450 °C) kunye ne-hard brazing (>450 °C) kuxhomekeke kubushushu apho izinto ze-brazing zifudunyezwa khona.

Ukuwelda kweLaser yeBini Beam
Ukuwelda ngemiqadi emibini kuvumela ulawulo oluguquguqukayo nolulula lwexesha kunye nendawo yokukhanyiselwa nge-laser, ngaloo ndlela kulungisa ukusasazwa kwamandla.
 
Isetyenziswa kakhulu ekudibaniseni i-aluminium kunye ne-magnesium alloys nge-laser, ukuwelda i-splice kunye ne-lap plate kwiimoto, ukubethela i-laser kunye nokuwelda i-deep fusion.
 
Umqadi ophindwe kabini ungafunyanwa ngee-laser ezimbini ezizimeleyo okanye ngokuqhekeka komqadi nge-splitter yomqadi.
 
Ezi beam zimbini zingaba yindibaniselwano yeelaser ezineempawu ezahlukeneyo ze-time domain (i-pulsed vs. continuous), ii-wavelengths ezahlukeneyo (ii-mid-infrared vs. visible wavelengths) kunye namandla ahlukeneyo, anokukhethwa ngokwezinto ezicutshungulwayo.

4. Ukuwelda kweLaser Composite
Ngenxa yokusetyenziswa kwe-laser beam njengomthombo wobushushu kuphela, i-single heat source laser welding inezinga lokuguqulwa kwamandla eliphantsi kunye nezinga lokusetyenziswa, i-weld base material port interface kulula ukuyivelisa i-misalignment, kulula ukuyivelisa i-pores kunye ne-cracks kunye nezinye iziphene, ukuze usombulule le ngxaki, ungasebenzisa iimpawu zokufudumeza zeminye imithombo yobushushu ukuphucula ukufudumeza kwe-laser kwindawo yokusebenza, edla ngokuba yi-laser composite welding.
 
Uhlobo oluphambili lwe-laser composite welding yi-composed welding ye-laser kunye ne-electric arc, isiphumo se-1 + 1 > 2 silandelayo.
 
emva komqadi welaser kufutshane ne-arc esetyenzisiweyo,uxinano lwe-electron luncitshiswe kakhulu, ilifu leplasma eliveliswa yi-laser welding liyancitshiswa, nto leyoingenza izinga lokufunxwa kwelaser liphucuke kakhulu, ngelixa i-arc kwisiseko sezinto ezifudumeza kwangaphambili iya kwandisa ngakumbi izinga lokufunxwa kwelaser.
 
2. ukusetyenziswa kwamandla aphezulu kwe-arc kunye netotaliukusetyenziswa kwamandla kuya kwandiswa.
 
3, indawo yokusebenza kwe-laser welding incinci, kulula ukubangela ukungalingani kwezibuko le-welding, ngelixa isenzo sobushushu se-arc sikhulu, esinokuthiukunciphisa ukungalingani kwezibuko lokuweldaKwangaxeshanye,umgangatho wokuwelda kunye nokusebenza kakuhle kwe-arc kuyaphuculwangenxa yesiphumo sokugxila kunye nesikhokelo somqadi welaser kwi-arc.
 
4, ukuwelda nge-laser enobushushu obuphezulu, indawo enkulu echaphazelekileyo bubushushu, isantya sokupholisa nokuqina ngokukhawuleza, kulula ukuvelisa imifantu kunye neembobo; ngelixa indawo ye-arc echaphazelekileyo bubushushu incinci, nto leyo enokunciphisa i-gradient yobushushu, ukupholisa, isantya sokuqina,inokunciphisa kwaye isuse ukuveliswa kweembobo kunye nemifantu.
 
Kukho iindlela ezimbini eziqhelekileyo zokuwelda nge-laser-arc composite: ukuwelda nge-laser-TIG composite (njengoko kubonisiwe ngezantsi) kunye nokuwelda nge-laser-MIG composite.

Kukwakho nezinye iindlela zokuwelda ezifana ne-laser kunye ne-plasma arc, i-laser kunye ne-inductive heat source compound welding.
