Ukuwelda ngeLaser kwezinto zobhedu: ILaser eluhlaza okwesibhakabhaka vs ILaser eluhlaza

Ukuwelda nge-laser yindlela entsha yokucubungula esebenza kakuhle kakhulu. Inkqubo yokwenziwa kwe-laser machining yisiphumo sokusebenzisana phakathi komqadi othile wamandla kunye nezinto. Izinto ngokubanzi zahlulwe zibe ziintsimbi kunye nezingezizo iintsimbi. Izinto zesinyithi ziquka intsimbi, isinyithi, ubhedu, i-aluminium, kunye nee-alloys ezinxulumene nazo, ngelixa izinto ezingezizo iintsimbi ziquka iglasi, umthi, iplastiki, ilaphu, kunye nezinto ezibuthathaka. Ukuveliswa kwe-laser kusetyenziswa kumashishini amaninzi, kodwa ukuza kuthi ga ngoku, ukusetyenziswa kwayo kukwiindidi zezinto.

Ishishini leLaser lifuna ukuqinisa uphando malunga neempawu zezinto ezibonakalayo

ETshayina, uphuhliso olukhawulezayo lweshishini le-laser luqhutywa yimfuno enkulu yezicelo. Nangona kunjalo, uninzi lwabavelisi bezixhobo ze-laser bagxila kakhulu kunxibelelwano phakathi komqadi we-laser kunye nezinto zoomatshini, abanye becinga ngokuzenzekela kwezixhobo. Kukho ukunqongophala kophando ngezinto, njengokuchonga ukuba zeziphi iiparameter zemitha ezifanelekileyo kwizinto ezahlukeneyo. Lo msantsa kuphando uthetha ukuba ezinye iinkampani ziphuhlisa izixhobo ezintsha kodwa azikwazi ukuhlola izicelo zazo ezintsha. Iinkampani ezininzi ze-laser zineenjineli ze-optical kunye ne-mechanical kodwa zimbalwa iinjineli zesayensi yezinto, nto leyo egxininisa isidingo esingxamisekileyo sophando oluthe kratya malunga neempawu zezinto.

Ukukhanya Okuphezulu Kobhedu Kukhuthaza Uphuhliso Lwetekhnoloji Yelaser Eluhlaza Neluhlaza Okwesibhakabhaka

Kwizinto zesinyithi, ukucutshungulwa kwentsimbi nesinyithi nge-laser kuye kwahlolwa kakuhle. Nangona kunjalo, ukucutshungulwa kwezixhobo ezibonisa ukukhanya okuphezulu, ingakumbi ubhedu kunye ne-aluminium, kusahlolwa. Ubhedu lusetyenziswa kakhulu kwiintambo, izixhobo zasekhaya, izixhobo ze-elektroniki zabathengi, izixhobo zombane, izinto ze-elektroniki, kunye neebhetri ngenxa yokuqhuba kwayo kakuhle kobushushu kunye nombane. Nangona iminyaka emininzi yomzamo, iteknoloji ye-laser iye yasokola ukucutshungulwa kobhedu ngenxa yeempawu zayo.

Okokuqala, i-copper ine-reflectivity ephezulu, ene-reflectivity rate ye-90% kwi-infrared laser eqhelekileyo ye-1064 nm. Okwesibini, i-thermal conductivity egqwesileyo ye-copper ibangela ukuba ubushushu buphele ngokukhawuleza, okwenza kube nzima ukufezekisa isiphumo sokucubungula esifunekayo. Okwesithathu, kufuneka ii-laser ezinamandla aphezulu ukuze kucutshungulwe, nto leyo enokukhokelela ekuguqulweni kwe-copper. Nokuba i-welding igqityiwe, iziphene kunye ne-welds ezingaphelelanga ziqhelekile.

Emva kweminyaka yophando, kufunyenwe ukuba iilaser ezinee-wavelengths ezimfutshane, njengeelaser eziluhlaza okwesibhakabhaka neziluhlaza okwesibhakabhaka, zilungele ngakumbi ukuwelda ubhedu. Oku kuye kwakhokelela ekuphuhlisweni kwetekhnoloji yelaser eluhlaza okwesibhakabhaka neziluhlaza okwesibhakabhaka.

Ukutshintsha ukusuka kwiilaser ze-infrared ukuya kwiilaser eziluhlaza ezinobude obuyi-532 nm kunciphisa kakhulu ukuqaqamba. Ilaser ye-532 nm ubude ivumela ukudibana okuqhubekayo komqadi welaser nezinto zobhedu, nto leyo ezinzisa inkqubo yokuwelda. Isiphumo sokuwelda kwi-copper nge-532 nm laser siyafana nese-1064 nm laser kwintsimbi.

ETshayina, amandla orhwebo e-green lasers afikelele kwi-500 watts, ngelixa kwihlabathi liphela afikelele kwi-3000 watts. Isiphumo sokuwelda sibaluleke kakhulu kwiindawo zebhetri ye-lithium. Kwiminyaka yakutshanje, ukuwelda kwe-green laser yobhedu, ingakumbi kushishino olutsha lwamandla, kuye kwaba yinto ephambili.

Okwangoku, inkampani yaseTshayina iphumelele ukuphuhlisa i-laser eluhlaza edityaniswe ngokupheleleyo nefayibha enamandla ephuma kwi-1000 watts, nto leyo eyandisa kakhulu usetyenziso olunokubakho lokuwelda ngekopolo. Le mveliso yamkelwe kakuhle kwimarike.

Kwiminyaka emithathu edlulileyo, iteknoloji entsha ye-blue laser ifumene ingqalelo kushishino. Ii-blue lasers, ezinobude obujikeleze i-450 nm, ziwela phakathi kwe-ultraviolet kunye ne-green lasers. Ukufunxwa kwe-blue laser kwi-copper kungcono kune-green laser, okunciphisa ukuqaqamba kwayo kube ngaphantsi kwe-35%.

Ukuwelda nge-laser eluhlaza okwesibhakabhaka kungasetyenziselwa zombini ukuwelda nge-thermal conduction kunye nokuwelda nge-deep penetration, kufezekisa "ukuwelda okungena-spatter" kunye nokunciphisa ukuxinana kwe-weld. Ngaphandle kokuphucula umgangatho, ukuwelda nge-laser eluhlaza okwesibhakabhaka kobhedu kukwabonelela ngeenzuzo ezibalulekileyo zesantya, kuba ubuncinane zikhawuleza ngokuphindwe kahlanu kune-infrared laser welding. Isiphumo esifunyenwe nge-3000-watt infrared laser sinokufezekiswa nge-500-watt blue laser, oko konga kakhulu amandla kunye nombane.

Abavelisi beLaser abaphuhlisa iiLaser eziluhlaza okwesibhakabhaka

Abavelisi abaphambili bee-laser eziluhlaza okwesibhakabhaka baquka iLaserline, iNuburu, iUnited Winners, iBWT, kunye neHan's Laser. Okwangoku, ii-laser eziluhlaza okwesibhakabhaka zisebenzisa indlela yetekhnoloji ye-semiconductor edityanisiweyo ngefayibha, ehlala ixesha elide kubuninzi bamandla. Ke ngoko, ezinye iinkampani ziye zaphuhlisa i-dual-beam composite welding ukuze kufezekiswe iziphumo ezingcono ze-copper welding. I-dual-beam welding ibandakanya ngaxeshanye ukusebenzisa i-blue laser beams kunye ne-infrared laser beams kwi-copper welding, kunye neendawo ezilungelelaniswe ngononophelo zeendawo ezimbini ze-beam ukusombulula imiba ephezulu yokubonakalisa ngelixa kuqinisekiswa ubuninzi bamandla obaneleyo.

Ukuqonda iimpawu zezinto ezibonakalayo kubalulekile xa kusetyenziswa okanye kuphuhliswa ubuchwepheshe be-laser. Nokuba usebenzisa ii-laser eziluhlaza okwesibhakabhaka okanye eziluhlaza, zombini zinokuphucula ukufunxwa kwe-laser yikopolo, nangona ii-laser eziluhlaza okwesibhakabhaka neziluhlaza ezinamandla aphezulu okwangoku zibiza kakhulu. Kukholelwa ukuba njengoko iindlela zokucubungula zikhula kwaye iindleko zokusebenza kwee-laser eziluhlaza okwesibhakabhaka okanye eziluhlaza zincipha ngokufanelekileyo, imfuno yemarike iya kunyuka ngokwenene.
