Ukubuyiselwa kocingo lwentsimbi olukhandiweyo nge-laser

Iingcali zokulungisa zijongene nomceli mngeni onzima. Iingcingo zembali zifuna ukulungiswa ngononophelo. Nangona kunjalo, iindlela zokucoca zemveli zihlala zonakalisa izinto zakudala. Ukuqhumisa isanti kuyawutshabalalisa umphezulu. Iikhemikhali ezisusa iikhemikhali zishiya iintsalela ezinobuthi. Ukulungiswa kwengcingo yesinyithi eyenziwe nge-laser kunika isisombululo esingcono. Le teknoloji isebenzisa ukukhanya okugxile. Ukukhanya kuyawuphehla umhlwa. Le nkqubo ishiya isinyithi singabi nasici. Eli nqaku lichaza iingenelo zobugcisa zokususwa kwe-laser. Likwachaza neengenelo zokuwelda nge-laser ephathwayo.

Umngeni Wezinto Eziphathekayo: Intsimbi Eyenziwe Ngokwenyani Xa Ithelekiswa Nentsimbi Ethambileyo

Abasebenzi kufuneka bachonge isinyithi. Iingcingo zanamhlanje zihlala zenziwe ngentsimbi ethambileyo. Isinyithi esithambileyo sinesakhiwo esifanayo sekristale. Simelana nokucocwa okunamandla.

Iingcingo zembali zihlala zenziwe ngentsimbi yokwenyani. Intsimbi yokwenyani yahlukile kwintsimbi. Yinto edityanisiweyo. Iqulethe i-matrix yentsimbi ethambileyo. Ikwanazo neentambo ze-slag zesinyithi esithambileyo. Ezi ntambo ze-slag zibonelela ngokumelana nokugqwala. Zenza ingqolowa efana nomthi.

Ukuqhushumba kwesanti konakalisa esi sakhiwo. Uthuli olurhabaxa lubetha umphezulu. Uthuli lutshabalalisa intsimbi ethambileyo. Uthuli luveza imicu yenkunkuma. Olu thuli ludala imingxunya enzulu. Imingxunya ibamba umswakama. Uthuli olubanjiweyo lukhawulezisa ukugqwala.

Ukucocwa nge-laser kukhusela i-substrate. Umqadi we-laser ujolise kwii-oxides. Ubonakalisa isinyithi esisisiseko. Olu khetho lugcina iifayibha ze-slag. Lugcina iimpawu zezixhobo zokuqala. Lugcina ukuthembeka kwembali.

Iteknoloji yokucoca ngeLaser: Indlela esebenza ngayo i-Ablation

Ukucoca nge-laser kusebenzisa inkqubo ebizwa ngokuba yi-laser ablation. Lo matshini ukhupha ukukhanya okunamandla kakhulu.

1. Ifiziksi yokususa

Umthombo welaser uvelisa umqadi. Umqadi ubetha kwingcolisi. Umhlwa kunye nepeyinti zifunxa amandla. Oku kufunxa kudala ubushushu. Ubushushu bubangela ukwanda ngokukhawuleza kobushushu. Ingcolisi iyajika ibe ngumphunga. Ijika ukusuka kwinto eqinileyo ibe yigesi.

Isinyithi esingaphantsi sihlala sipholile. Isinyithi sibonakalisa ubude be-laser. Olu kukhanya kuthintela umonakalo. Le nkqubo iyazithintela. Ukucoca kuyaphela kumphezulu wesinyithi ongenanto.

2. IiLaser zeWave ezityhalwayo kunye neziQhubekekayo

Iiprojekthi zokubuyisela zisebenzisa iintlobo ezimbini ze-laser.

IiLaser ezityhalwayo (100W – 500W):

Indlela yokusebenza: Ezi lasers zikhupha iipulses ezimfutshane.

Isenzo: Iipulses zenza amandla aphezulu.

Inzuzo: Zicoca iindawo ezithambileyo. Zigcina i-patina. Zithintela ukwakheka kobushushu.

IiLaser ze-Continuous Wave (CW) (1000W – 3000W):

Indlela yokusebenza: Ezi lasers zikhupha umqadi oqhubekayo.

Isenzo: Umqadi unika amandla angaguqukiyo.

Inzuzo: Zisusa ipeyinti etyebileyo ngokukhawuleza. Zicoca intsimbi enzima yesakhiwo.

Umngcipheko: Zifaka ubushushu obukhulu. Abaqhubi kufuneka bahambe ngokukhawuleza. Ukuhamba kancinci kuyajika iindawo ezincinci.

3. Ukucoca iiJometri ezintsonkothileyo

Ucingo lwentsimbi olubunjiweyo lunoyilo oluntsonkothileyo. Luquka imisongo, iikhola kunye namagqabi.

Ukuqhuma kwesanti kuyasilela: I-Grit ayifuni iindawo ezinzulu. I-Grit ihlala kwiindawo ezixineneyo.

I-Laser Iyaphumelela: I-laser isebenza ngendlela ebonakala ngayo. Umqadi ungena kwiindawo ezinzulu. Ikhupha umhlwa ofihlakeleyo. Icoca ngaphakathi "kwezikhonkwane" zocingo. Olu buchule luthintela "ukugquma komhlwa."

Ukulungiswa kweSakhiwo: Ukuwelda ngeLaser ephathwayo

Ukulungiswa kwesakhiwo kubandakanya ukulungiswa kwesakhiwo. Uqhagamshelo lwemishini luyaphuka ngokuhamba kwexesha. Ukuwelda kwendabuko kubeka umngcipheko. Ukuwelda kwe-arc (MIG okanye TIG) kuvelisa ubushushu obuphezulu. Ubushushu obuphezulu budala indawo enkulu echaphazelekileyo bubushushu (HAZ). Ukuwelda okukhulu kubangela ukugoba.

Ukuwelda nge-laser ephathwa ngesandla kusombulula le ngxaki.

1. Ukuchaneka kunye nobushushu obuphantsi

Ukuwelda nge-laser kugxila kumandla. Umqadi unyibilikisa indawo encinci. Oku kuchanekileyo kunciphisa i-HAZ. Isinyithi esijikelezileyo sihlala sipholile. Abaqhubi banokuchukumisa inxalenye ngoko nangoko. Olu phawu lukhusela ii-finials ezithambileyo.

2. Itekhnoloji yokuWelda eQhekezelayo

Ucingo lwembali ludla ngokuba nezikhewu. Iindawo eziphukileyo azilingani kakuhle. Umqadi omncinci welaser awunakuzivala ezi zikhewu.

Iteknoloji: Abawelda nge-laser basebenzisa iintloko “ezigungqayo”.

Indlela yokusebenza: Izipili ziyawujika umqadi.

Isiphumo: Umqadi udala ichibi elikhulu lokunyibilika. Uvala izikhewu ukusuka kwi-1.0 mm ukuya kwi-2.0 mm. Udala ii-fillet welds eziqinileyo.

3. Ukugqiba ubuhle

Ii-laser welds zibukeka zigudile. Zifuna ukugaywa okuncinci. Ii-welding zemveli zifana ne-slag. Ukugaywa kususa ubume bokuqala. Ii-laser welds zishiya umphezulu ucocekile.

Uhlalutyo lokuthelekisa: Iindlela zeLaser vs. zeMveli

Uhlalutyo: Ukucocwa nge-laser kususa inkunkuma yesibini. Ukuqhumisa isanti kudala amafu othuli. Ukucocwa nge-laser kudala umphunga olawulekayo. Oku kunciphisa kunceda iindawo zemisebenzi zasezidolophini.

Ukhuseleko Lokusebenza Nokuthobela Imithetho

Iinkqubo zokucoca nge-laser zisebenzisa ii-laser zeKlasi yesi-4. Olu didi lumele ingozi yokhuseleko. Abaqhubi kufuneka balandele imigaqo engqongqo.

1. Ukhuseleko lwamehlo

Ukukhanya kwelaser konakalisa iliso. Imisebe ethe ngqo itshisa i-retina. Ukukhanya okusasazekileyo kubangela ubumfama.

Umthetho: Abasebenzi mabanxibe iiglasi zokhuseleko.

Umgangatho: Iiglasi kufuneka zibe nobuninzi be-Optical Density (OD) obuyi-7+.

Ukuseta: Abaqhubi kufuneka bamisele indawo elawulwa yiLaser (LCA). Bafanele basebenzise amakhethini akhuselekileyo kwilaser.

2. Ukukhupha umsi

Ukukhupha inkunkuma kuvelisa umsi. Ukufuma kwepeyinti kukhupha iityhefu. Iifensi ezindala zihlala zinelothe.

Ingozi: I-plume iqulethe amasuntswana e-load. Iqulethe iiVolatile Organic Compounds (ii-VOC).

Isisombululo: Abaqhubi basebenzisa izixhobo zokukhupha umsi. Izixhobo zokukhupha umsi zisebenzisa izixhobo zokucoca i-HEPA. Izixhobo zokukhupha umsi zibamba uthuli kwindawo ephuma kuyo.

3. Ukuthintela uMlilo

Ileyiza ithwala amandla obushushu. Itshisa izinto ezitshayo.

Imigaqo: Coca indawo. Susa amagqabi omileyo. Manzisa umhlaba. Gcina izicimi-mlilo kufutshane.

Imigangatho yoLungiso lomphezulu

Iinjineli zichaza amanqanaba okucoceka. Ukucocwa nge-laser kuyahlangabezana nale migangatho.

I-SSPC-SP 1 (Ukucoca iSolvent): Iilaser zisusa iioyile.

I-SSPC-SP 10 (Intsimbi Ekufutshane Nemhlophe): Iilaser zisusa i-95% yomhlwa.

Iprofayili yeAnchor: Iilaser zenza ubume obuncinci. Azidali iprofayili enzulu.

Icebo Lokugquma: Sebenzisa ii-epoxy primers ezisetyenziswa ngqo kwisinyithi (DTM). Ezi primers zinamathela kwiindawo ezicociwe nge-laser. Zisivala kakuhle isinyithi.

Isiphelo

Ukulungiswa kocingo lwentsimbi olubunjiweyo nge-laser kuyayitshintsha imboni. Kuthatha indawo yokukrazula ngokukhupha. Kuthatha indawo yamandla ngobuchule.

Iindlela zemveli zibeka phambili isantya. Iindlela zelaser zibeka phambili ukugcinwa. Ukuqhumisa isanti konakalisa ujongano lwe-slag. Ukucocwa ngelaser kugcina ujongano lwe-slag. Kugcina ubungakanani bokuqala. Kuvumela ukulungiswa okungabonakaliyo.

Abakhi basebenzisa obu buchwephesha. Bafumana ithuba lokukhuphisana. Banikezela ngenkonzo ecocekileyo. Banikezela ngenkonzo ekhuselekileyo. Banikezela ngeziphumo ezigqwesileyo.

Imibuzo Ebuzwa Rhoqo (Imibuzo Ebuzwa Rhoqo)

Umbuzo: Ngaba ukucocwa nge-laser kungasusa ipeyinti yelothe? Impendulo: Ewe. I-laser iyayitshisa ipeyinti yelothe ibe ngumphunga. Abaqhubi kufuneka basebenzise ukukhupha umsi. I-extractor ibamba uthuli lwelothe. Le ndlela ithintela ungcoliseko lomhlaba.
