Ukugxila kwi-Laser Welding Ipharamitha ephambili emisela uzinzo lokungena kwe-Weld kunye nomgangatho we-Weld

In umatshini wokuwelda we-laser wesinyithiiinkqubo, iiparameters ezinje ngamandla, isantya sokudibanisa, kunye noseto lokushukuma zihlala zifumana ingqwalasela enkulu. Nangona kunjalo, enye yezona zinto ziyinyani

ichaza umda ophezulu wokusebenza kwe-welding yindawo yokugxila kwe-laser.

Ukuba ugxininiso lumiselwe ngokuchanekileyo kunempembelelo ngqo kubuninzi bamandla, ubunzulu bokungena, ukwakheka kwe-weld, kwanozinzo lokusebenza ngokubanzi kweizixhobo zelaser.

Ukuqonda nokulawula ngokuchanekileyo ukugxila kwelaser ke ngoko kubalulekile ekufezekiseni ukuwelda kwelaser ekumgangatho ophezulu.

I. Yintoni iLaser Focus?

Emva kokudlula kwilensi yokugxila, umqadi welaser uyadibana uye kwindawo ethile apho amandla axinene kakhulu—le ndawo yaziwa ngokuba yi-laser focus.

Kufuphi nendawo ephambili, umqadi welaser ubonisa ezi mpawu zilandelayo:

Ubungakanani obuncinci bendawo

Ubuninzi bamandla

Ukusebenza kakuhle kokufunxa izinto

Ngenxa yesi sizathu, nokuba utshintsho oluncinci kwindawo yokugxila—ngeemilimitha ezimbalwa kuphela—lunokubangela utshintsho olubonakalayo ekusebenzeni kwe-welding.

II. Iimeko Ezintathu Eziqhelekileyo Zokugxila kunye Neempawu Zazo Zenkqubo

Indawo yoGxilo (Akukho Defocus)

Xa indawo ephambili ibekwe ngqo kumphezulu wezinto zokusebenza okanye embindini wendawo yokuwelda, amandla elaser axinene kakhulu, nto leyo enika amandla okungena anamandla kakhulu.

Iimpawu:

Ubuninzi bamandla

Ubunzulu obukhulu bokungena

Ukuqaliswa kokuwelda ngokukhawuleza kunye nokusebenza kakuhle okuphezulu

Izicelo eziqhelekileyo:

Iinkqubo zokuwelda ezineemfuno eziphezulu zokungena

Izinto ezityebileyo okanye izicelo ezifuna ukungena ngokukhawuleza ngokupheleleyo

Xa kufuneka ukusetyenziswa kwamandla aphezulu, indawo yokugxila ku-zero idla ngokuba yeyona ikhethwayo.

Ukususa ukugxila okungalunganga (Gxila ngaphezu kweWorkpiece)

Xa indawo ephambili ibekwe ngaphezulu komphezulu wezinto zokusebenza, umqadi welaser uqala ukuhlukana ngaphambi kokuba ufikelele kwizinto, nto leyo ebangela ubungakanani obukhulu bebala.

Iimpawu:

Amandla asasazwa ngokulinganayo

Uzinzo oluphuculweyo lwedama lokuqubha elinyibilikisiweyo

Ubunzulu bokungena obuncitshisiweyo

Izicelo eziqhelekileyo:

Ukuwelda okuqhubekekayo kokungena nzulu

Iinkqubo ezifuna uzinzo oluphezulu lokuwelda kunye nokuhambelana komthungo

Ukuwelda ngepleyiti etyebileyo ukunciphisa ukuchitheka kunye nokuguquguquka kokuwelda

Ukugxila okungalunganga kugxininisa uzinzo kunye nokulawulwa kwenkqubo.

Ukugxila Okuhle (Jolisa Ngaphantsi Kwento Esebenzayo)

Xa indawo ephambili ibekwe ngaphantsi komphezulu wento yokusebenza, i-laser yenza indawo enkulu kumphezulu, inciphisa uxinano lwamandla kwindawo nganye yeyunithi.

Iimpawu:

Ukusasazwa kobushushu okufanayo ngakumbi

Inkangeleko yomphezulu ethambileyo

Ubunzulu bokungena obungaphantsi

Izicelo eziqhelekileyo:

Ukuwelda ngeshiti elincinci

Iiweld zokutywina umphezulu kunye nokuwelda kwelap

Izicelo ezineemfuno eziphantsi zokungena kodwa zifuna kakhulu inkangeleko yokuwelda

I-defocus elungileyo isetyenziswa rhoqo kwiimeko apho umgangatho womphezulu kunye nolawulo lwendawo echaphazeleka bubushushu zibalulekile.

III. Kutheni Ulawulo Lokugxila Lubaluleke Kangaka?

Imisela ngokuthe ngqo ukungena kwe-Weld

Okukhona ingqwalasela isondela kwindawo yokuwelda engundoqo, kokukhona uxinano lwamandla luphezulu kwaye ubunzulu bokungena buyanda.

Ichaphazela ukwakheka kwe-Weld kunye nokungaguquguquki

Ukuphambuka okugqithisileyo kokugxila kunokukhokelela kububanzi be-weld obungalinganiyo kunye nokwakheka komthungo ongaguqukiyo.

Iimpembelelo zokuQina kweNkqubo yokuWelda

Useto olufanelekileyo lokugxila lunceda ekunciphiseni ukuchitheka, ukunciphisa ukuguquguquka kokuwelda, kunye nokuphucula ukuthembeka kwimisebenzi yokuwelda eqhubekayo.

Ichaphazela Ngokungathanga Ngqo Ubomi Benkonzo Yezixhobo

Iimeko zokugxila ezingalunganga zinokubangela ukubonakaliswa kwamandla kunye nee-alamu zenkqubo, ezinokuchaphazela kakubi uzinzo lwexesha elide lwezixhobo ze-optical kunye nezombane.

IV. Iingcebiso Ezisebenzayo Zokulungisa Ukugxila

Kwizicelo zehlabathi lokwenyani, akukho lungiselelo lokugxila olusetyenziswa kwihlabathi liphela. Uhlengahlengiso lokugxila kufuneka lumiselwe ngokusekelwe kudibaniso lwezinto, kuquka:

Uhlobo lwezinto (intsimbi engatyiwayo, intsimbi yekhabhoni, i-aluminium alloy, njl.njl.)

Ubukhulu bezinto

Uqwalaselo lokuwelda (ukuwelda ngeempundu, ukuwelda ngeelaphu, ukuwelda ngeefillet)

Ukuhambelana kwesantya sokuwelda kunye namandla elaser

Kucetyiswa ukuba kuchongwe indawo efanelekileyo yokugxila ngokuwelda kwesilingo ngaphambi kokuveliswa ngokusesikweni kunye nokugcina useto oluhambelanayo ngexesha lokucubungula ibhetshi.

V. Isiphelo

Ukuwelda nge-laser esemgangathweni ophezulu kuxhomekeke ekuqondeni ngokuchanekileyo kunye nolawulo lwe-laser focus.

Ukulungiswa kokugxila akusiyonto nje yokulungelelanisa—yiparameter ebalulekileyo edibanisa ulawulo lwamandla, ingqiqo yenkqubo, kunye namava okuwelda.

Kuphela ngokwazi indlela yokugxila enokuzinza, isebenze kakuhle, kwaye ilawuleke ngokupheleleyoumatshini wokuwelda we-laser yesinyithiiziphumo ziya kufezekiswa kwiimeko ezahlukeneyo zokuwelda.
