Iimpawu zeLaser Welding

Xa kuthelekiswa nezinye iindlela zokuwelda, ukuwelda ngelaser kunezi mpawu zilandelayo:

·Amandla agxilileyo, ukusebenza kakuhle kwe-welding, ukuchaneka okuphezulu kokusebenza, kunye nomlinganiselo omkhulu wobunzulu ukuya kububanzi bomthungo we-weld.

·Ukufakwa kobushushu obuphantsi, indawo encinci echaphazelekileyo kubushushu, uxinzelelo oluncinci lokushiyeka, kunye nokuguqulwa okuphantsi kwendawo yokusebenza.

·I-welding engadibanisiyo, i-fiber optic transmission, ukufikeleleka kakuhle, kunye nenqanaba eliphezulu lokuzisebenzela.

·Uyilo oludibeneyo oluguquguqukayo, ukugcina izinto eziluhlaza.

·Amandla e-welding anokulawulwa ngokuchanekileyo, ukuqinisekisa iziphumo ezizinzileyo ze-welding kunye nokubonakala kakuhle kwe-welding.

·Insimbi engenasici inokufezekisa iziphumo ezilungileyo ze-welding usebenzisa i-standard square wave.

·Xa uyila izakhiwo ezidityanisiweyo, zama ukugcina amanqaku e-weld kude nezinto ezingezizo ezentsimbi kangangoko kunokwenzeka.

·Ukuhlangabezana neemfuno zamandla kunye nenkangeleko, kuyacetyiswa ukuba ugcine indawo eyaneleyo ye-welding kunye nobukhulu be-workpiece.

·Ngexesha le-welding, kubalulekile ukuqinisekisa ukucoceka kwendawo yokusebenza kunye nokoma kokusingqongileyo.

·Izinto ze-aluminium alloy zine-reflection ephezulu;ke ngoko, amandla aphezulu encopho ye-laser ayadingeka ngexesha le-welding.

·Iintanda zivame ukwenzeka ngexesha le-pulse spot welding, echaphazela amandla e-welding.

·Ukubunjwa kwezinto eziphathekayo kukulungele ukuhlukana, okukhokelela ekutshizeni.Kuyacetyiswa ukuba ukhethe izixhobo ezikumgangatho ophezulu.

·Ngokubanzi, ukusebenzisa ubungakanani bendawo enkulu kunye nobubanzi be-pulse emide kunokufikelela kwiziphumo ezingcono zokuwelda.

·Izixhobo zobhedu zinokubonakala okuphezulu xa kuthelekiswa ne-alloys ye-aluminium, efuna amandla aphezulu e-laser yokuwelda.Intloko ye-laser kufuneka ithotywe kwi-angle ethile.

·Kwii-alloys ezithile zobhedu, ezifana nobhedu kunye nobhedu, ubunzima be-welding buyanda ngenxa yefuthe lezinto ze-alloy.Ingqalelo kufuneka ihlawulwe ekukhethweni kweeparamitha zenkqubo ye-welding.

Ukuwelda kweMetal okungafaniyo

·Ingaba isisombululo esiluqilima singenziwa.

·Ngaba kukho umahluko omkhulu kwi-electronegativity phakathi kweentsimbi ezingafaniyo.

·Ezinye izinto ezinempembelelo.

Nokuba iintsimbi ezingafaniyo zinokubumba iindawo zokuwelda ezikumgangatho ophezulu ikakhulu kuxhomekeke kwiipropati zomzimba, iipropathi zekhemikhali, ukwakheka kweekhemikhali, kunye nemilinganiselo yenkqubo yesinyithi ekufuneka idityaniswe.Oku kujongwa ngokwesiqhelo kule miba ilandelayo:

·Ukuba isisombululo esiluqilima sinokubunjwa kuxhomekeke ekubeni iintsimbi ezingafaniyo zinokunyibilika ngokufanayo kulwelo nakwilizwe eliqinileyo.Kuphela xa zinokunyibilika komnye nomnye ngokungenasiphelo, i-weld joint weld inokwakheka.Ngokubanzi, ukunyibilika okubalulekileyo, okanye ukunyibilika okungenamkhawulo, kufumaneka kuphela xa umahluko weradiyasi yeathom phakathi kwezi zinyithi zimbini ungaphantsi kwe-14% ukuya kwi-15%.

·Nokuba kukho umahluko omkhulu kwi-electronegativity phakathi kweentsimbi ezahlukeneyo nako kubalulekile.Okukhona umahluko omkhulu, kokukhona womelele ukunxulumana kwabo kweekhemikhali, okukholisa ukukhokelela ekwakhiweni kweekhompawundi kunezisombululo eziqinileyo.Ngenxa yoko, i-solubility yesisombululo esiqinileyo esakhiweyo siyancitshiswa, kwaye amandla okudibanisa i-weld nawo aphantsi.

·Ukongeza, ukuwelda kweentsimbi ezingafaniyo kuchaphazeleka kakhulu ziipropathi ezinje ngeendawo zokunyibilika, i-coefficients yokwandiswa kwe-thermal, i-thermal conductivities, ukushisa okuthe ngqo, i-oxidizability, kunye nokubonakaliswa kwezinto ezibandakanyekayo.Okukhona umahluko omkhulu kwezi zakhiwo zomzimba, kokukhona kuba ngumceli mngeni ukuwelda, kwaye kokukhona ubuthathaka amandla esiphumo se-weld joint sithanda ukuba.

·Ngokuqhelekileyo, i-laser welding yezixhobo zetsimbi ezahlukeneyo ezifana nentsimbi enobhedu, i-aluminiyam, kunye ne-nickel, kunye nobhedu olune-nickel, ibonisa ukuwelda okulungileyo, okukhokelela kumgangatho owanelisayo we-welding.
