Laser Welding of Materials Copper: Blue Laser VS Green Laser

I-Laser welding yindlela ephumayo ephezulu yokusebenza kakuhle. Inkqubo ye-laser machining yisiphumo sokusebenzisana phakathi kwe-beam ethile yamandla kunye nezinto eziphathekayo. Iimathiriyeli zihlelwa ngokubanzi ngokwezinyithi nezingezizo iintsimbi. Izinto zetsimbi ziquka intsimbi, intsimbi, ubhedu, i-aluminiyam, kunye ne-alloys ehambelana nazo, ngelixa izinto ezingezona zetsimbi ziquka iglasi, umthi, iplastiki, ilaphu kunye nezixhobo ezinqabileyo. Ukwenziwa kweLaser kusetyenziswa kumashishini amaninzi, kodwa ukuza kuthi ga ngoku, ukusetyenziswa kwayo kuphakathi kwezi ndidi zezinto eziphathekayo.

Ushishino lweLaser lufuna ukomeleza uPhando kwiiPropati zeMpahla

E-China, uphuhliso olukhawulezayo loshishino lwe-laser luqhutywa yimfuno enkulu yezicelo. Nangona kunjalo, uninzi lwabavelisi bezixhobo ze-laser bagxile ikakhulu ekusebenzisaneni phakathi komqadi we-laser kunye nezixhobo zoomatshini, abanye bejonga izixhobo ezizenzekelayo. Kukho ukungabikho kophando kwizinto eziphathekayo, ezifana nokumisela ukuba yeyiphi imilinganiselo ye-beam efanelekileyo kwizinto ezahlukeneyo. Lo msantsa kuphando uthetha ukuba ezinye iinkampani ziphuhlisa izixhobo ezitsha kodwa azikwazi ukuphonononga izicelo zazo ezitsha. Iinkampani ezininzi zelaser zineenjineli ze-optical kunye nezoomatshini kodwa zimbalwa iinjineli zesayensi yezinto, ziqaqambisa imfuno engxamisekileyo yophando olongezelelekileyo kwiipropathi zezinto eziphathekayo.

Ukubonakaliswa okuphezulu kweCopper kuKhuthaza uPhuhliso lweTekhnoloji yeLaser eluhlaza kunye neBlue

Kwizixhobo zetsimbi, ukucutshungulwa kwe-laser yensimbi kunye nentsimbi kuye kwahlolisiswa kakuhle. Nangona kunjalo, ukusetyenzwa kwezixhobo eziphezulu zokukhanya, ngakumbi ubhedu kunye ne-aluminium, kusahlolwa. Ubhedu lusetyenziswa kakhulu kwiintambo, izixhobo zombane zasekhaya, i-elektroniki yabathengi, izixhobo zombane, izinto ze-elektroniki, kunye neebhetri ngenxa ye-thermal kunye ne-conductivity yombane. Nangona iminyaka emininzi yokuzama, iteknoloji ye-laser iye yanzima ukwenza ubhedu ngenxa yeempawu zayo.

Okokuqala, ubhedu lunokubonakala okuphezulu, kunye ne-90% yezinga lokubonisa i-1064 nm infrared laser eqhelekileyo. Okwesibini, i-copper egqwesileyo ye-thermal conductivity ibangela ukuba ukushisa kuphele ngokukhawuleza, okwenza kube nzima ukufezekisa umphumo oyifunayo. Okwesithathu, iilaser zamandla aphezulu ziyafuneka ukuze kusetyenzwe, nto leyo enokukhokelela kuguquko lobhedu. Nangona i-welding igqityiwe, iziphene kunye ne-welds ezingaphelelanga ziqhelekileyo.

Emva kweminyaka yokuphonononga, kuye kwafunyaniswa ukuba iilaser ezinobude obufutshane obufana nelaser eluhlaza kunye neblue, zifaneleke ngakumbi ukuwelda ubhedu. Oku kuqhubele phambili uphuhliso lwetekhnoloji yelaser eluhlaza naluhlaza.

Ukutshintshela kwi-laser ye-infrared ukuya kwi-laser eluhlaza kunye ne-532 nm wavelength kunciphisa kakhulu ukubonakala. I-laser ye-532 nm ye-wavelength ivumela ukudibanisa ngokuqhubekayo kwe-laser beam kwizinto zobhedu, ukuzinzisa inkqubo ye-welding. Impembelelo ye-welding kwi-copper ene-532 nm laser ifaniswa naleyo ye-1064 nm laser kwintsimbi.

E-China, amandla orhwebo e-laser eluhlaza afikelele kwi-500 watts, ngelixa kumazwe ngamazwe afikelele kwi-3000 watts. Umphumo we-welding ubaluleke kakhulu kumacandelo ebhetri ye-lithium. Kwiminyaka yakutshanje, ukuwelda kwe-laser eluhlaza yobhedu, ngakumbi kwishishini elitsha lamandla, kuye kwaba yinto ebalaseleyo.

Okwangoku, inkampani yaseTshayina iphuhlise ngempumelelo i-laser eluhlaza edityaniswe ngokupheleleyo nefiber enamandla ephuma kwi-1000 watts, yandisa kakhulu izicelo ezinokubakho zokuwelda ubhedu. Imveliso yamkelwa kakuhle kwimarike.

Kwiminyaka emithathu edlulileyo, itekhnoloji entsha yelaser eluhlaza ifumene ingqalelo kwishishini. Iilaser eziluhlaza, ezinobude obujikeleze i-450 nm, ziwela phakathi kwe-ultraviolet kunye ne-laser eluhlaza. Ukufunxwa kwelaser eluhlaza okwesibhakabhaka kubhedu kubhetele kunelaser eluhlaza, kunciphisa ukubonakaliswa ukuya ngaphantsi kwe-35%.

I-blue laser welding ingasetyenziselwa zombini i-thermal conduction welding kunye ne-welding yokungena enzulu, ukuphumeza "i-spatter-free welding" kunye nokunciphisa i-weld porosity. Ngaphandle kokuphucula umgangatho, ukuwelda ngelaser eluhlaza okwesibhakabhaka kukwabonelela ngezibonelelo ezikhawulezayo zesantya, ukukhawuleza ngokuphindwe kahlanu kune-infrared laser welding. Umphumo ophunyeziweyo nge-laser ye-infrared ye-3000-watt inokufezekiswa nge-500-watt blue laser, igcina kakhulu amandla kunye nombane.

Abavelisi beLaser abaPhuhlisa iiLaser eziBlue

Abavelisi abaphambili beelases eziluhlaza baquka iLaserline, Nuburu, United Winners, BWT, kunye neLaser kaHan. Okwangoku, iilaser eziluhlaza zisebenzisa indlela yetekhnoloji yefiber-coupled semiconductor, ethi ishiyeke kancinci kuxinzelelo lwamandla. Ke ngoko, ezinye iinkampani ziye zaphuhlisa i-welding ye-dual-beam composite ukufezekisa iziphumo ezingcono zobhedu. I-welding ye-double-beam ibandakanya kwangaxeshanye ukusebenzisa imiqadi yelaser eluhlaza kunye nemiqadi ye-laser ye-infrared yokuwelda ubhedu, kunye nezikhundla ezilungelelanisiweyo ezilungelelanisiweyo zamabala amabini okusombulula imiba ephezulu yokubonakalisa ngelixa uqinisekisa ukuxinana kwamandla okwaneleyo.

Ukuqonda iimpawu zemathiriyeli kubalulekile xa usebenzisa okanye uphuhlisa itekhnoloji yelaser. Nokuba zisebenzisa iilaser eziluhlaza okanye eziluhlaza, zombini zinokuphucula ukufunxwa kobhedu kweelases, nangona amandla aphezulu aluhlaza kunye neelases eziluhlaza zibiza ngoku. Kukholelwa ukuba njengoko iindlela zokusetyenzwa zikhula kwaye iindleko zokusebenza kweelaser eziluhlaza okanye eziluhlaza zincipha ngokufanelekileyo, imfuno yentengiso iya kunyuka ngokwenene.
