Zithini iinkqubo zokuwelda nge-laser?

Ukuwelda nge-laseryindlela entsha yokuwelda.Ukuwelda nge-laserIjolise kakhulu ekudibaniseni izinto ezibhityileyo kunye neendawo ezichanekileyo. Ingenza ukuwelda kwiindawo ezixineneyo, ukuwelda kwe-butt, ukuwelda kwe-stack, ukuwelda kwe-seal, njl. Iimpawu zayo zezi: umlinganiselo ophezulu, Ububanzi bomthungo buncinci, indawo echaphazelekileyo bubushushu incinci, ukuguqulwa kuncinci, kwaye isantya sokuwelda sikhawuleza. Umthungo wokuwelda uthambile kwaye mhle, kwaye akukho nyango lufunekayo okanye kufuneka iinkqubo zonyango ezilula emva kokuwelda. Umgangatho wokuwelda uphezulu kwaye akukho mingxunya. Ukungcola kwisinyithi esisisiseko kunokuncitshiswa kwaye kwenziwe ngcono. Isakhiwo sinokucocwa emva kokuwelda. Amandla kunye nokuqina kwesinyithi ubuncinane kufana okanye kudlule oko kwesinyithi esisisiseko. Ingalawulwa ngokuchanekileyo, indawo yokukhanya egxileyo incinci, ingabekwa ngokuchanekileyo okuphezulu, kwaye kulula ukuyiqonda ngokuzenzekelayo. Ingafezekisa ukuwelda phakathi kwezinto ezithile ezahlukeneyo.

1. Ukuwelda nge-laser self-fusion

Ukuwelda nge-laserIsebenzisa ulawulo oluhle kakhulu kunye noxinano olukhulu lwamandla elaser beam ukuze isebenze. Umqadi welaser ugxile kwindawo encinci ngenkqubo ye-optical, okwenza umthombo wobushushu oxineneyo kakhulu kwindawo edibeneyo ngexesha elifutshane kakhulu, ukuze into eza kudityaniswa inyibilike kwaye yenze indawo eqinileyo yokudityaniswa kunye nomthungo wokudityaniswa. Ukudityaniswa kwelaser: umlinganiselo omkhulu wobume; isantya esiphezulu kunye nokuchaneka okuphezulu; ukufakelwa kobushushu okuncinci kunye nokuguquguquka okuncinci; ukudityaniswa okungahambelaniyo; akuchaphazeleki ziimagnethi kwaye akukho mfuneko yokutshiza nge-vacuum.

2. Ukuwelda ngocingo lwe-laser filler

Ukuwelda ngocingo lwe-laser filleribhekisa kwindlela yokuzalisa kwangaphambili izixhobo ezithile zokuwelda kwi-weld uze uzinyibilikise nge-laser irradiation okanye ukuzalisa izixhobo zokuwelda ngelixa kusenziwa i-laser irradiation ukuze kwenziwe i-weld joint. Xa kuthelekiswa ne-non-filler wire welding, i-laser filler wire welding isombulula ingxaki yeemfuno ezingqongqo zokucubungula kunye nokuhlanganisa izinto zomsebenzi; inokuwelda iindawo ezityebileyo nezinkulu ngamandla aphantsi; ngokulungelelanisa ukwakheka kwe-filler wire, iipropati zesakhiwo sendawo yokuwelda zinokulawulwa.

3. Ukuwelda nge-laser ngenqwelo moya

Ukuwelda nge-laser ekudeibhekisa kwindlela yokuwelda nge-laser esebenzisa i-galvanometer yokuskena ekhawulezayo kakhulu ekucutshungulweni komgama omde. Inobuchaneko obuphezulu bokubeka izinto, ixesha elifutshane, isantya sokuwelda esikhawulezayo kunye nokusebenza kakuhle okuphezulu; ayizukuphazamisana nomatshini wokuwelda kwaye inongcoliseko oluncinci lweelensi ze-optical; ii-welds zalo naluphi na uhlobo zinokwenziwa ngokwezifiso ukuze kuphuculwe amandla olwakhiwo, njl. Ngokubanzi, umthungo wokuwelda awunalo ukhuseleko lwegesi kwaye i-spatter inkulu. Isetyenziswa kakhulu kwiipleyiti zentsimbi ezibhityileyo ezinamandla aphezulu, iipleyiti zentsimbi ezigayiweyo kunye nezinye iimveliso ezifana neepaneli zomzimba.

4. Ukugquma nge-laser

Umqadi welaser okhutshwa yijenereyitha yelaser ugxile kumphezulu wentambo yokuwelda kwaye ufudunyezwe, nto leyo ebangela ukuba intambo yokuwelda inyibilike (isinyithi esisisiseko asinyibiliki), imanzise isinyithi esisisiseko, izalise umsantsa odibeneyo, kwaye idityaniswe nesinyithi esisisiseko ukwenza i-weld ukuze kufezekiswe unxibelelwano oluhle.

5. Ukuwelda nge-laser swing

Ngokujija ilensi ebonakalisayo yangaphakathi yentloko yokuthunga, ukujija kwelaser kulawulwa ukuze kushukunyiswe ichibi lokuthunga, kukhuthazwe ukugcwala kwegesi echibini, kwaye kucocwe iinkozo. Kwangaxeshanye, kunokunciphisa uvakalelo lokujija kwelaser kwisithuba sezinto ezingenayo. Ifanelekile ngokukodwa kwi-welding alloy ye-aluminium, ubhedu kunye nezinto ezahlukeneyo.

6. Ukuwelda nge-laser arc hybrid

Ukuwelda nge-laser-arc hybridIdibanisa imithombo emibini yobushushu yelaser kunye ne-arc eneempawu zomzimba ezahlukeneyo ngokupheleleyo kunye neendlela zokuhambisa amandla ukwenza umthombo omtsha wobushushu osebenzayo. Iimpawu ze-hybrid welding: 1. Xa kuthelekiswa ne-laser welding, amandla okubopha ayaphucuka kwaye isakhiwo siyaphucuka. 2. Xa kuthelekiswa ne-arc welding, ukuguquguquka kuncinci, isantya se-welding siphezulu, kwaye ubunzulu bokungena bukhulu. 3. Sebenzisa amandla omthombo ngamnye wobushushu kwaye ulungise iziphene zawo, 1+1>2.
