Izilumkiso ze-Welding Aluminium Metal ene-2000W Fiber Laser Welding Machine

Kwimveliso yanamhlanje, ukusetyenziswa kwe2000W iimatshini zokuwelda ifayibha laserkuba ukuwelda iintsimbi ze-aluminiyam ziya zisanda. Nangona kunjalo, ukuqinisekisa umgangatho we-welding kunye nokhuseleko, le miba ilandelayo ilandelayo kufuneka iqatshelwe.

1. Unyango lobuso phambi kwe-welding

Ifilimu ye-oxide ebusweni bentsimbi ye-aluminium inokuchaphazela kakhulu umgangatho we-welding. Ukunyangwa ngokucokisekileyo komhlaba kufuneka kuqhutywe ukususa ifilimu ye-oxide, i-oil stains kunye nezinye izinto ezingcolileyo. Xa ishishini elithile leemoto lidibanisa isakhelo se-aluminiyam, ngenxa yokungahoywa kwonyango olungaphezulu, inani elikhulu leepores kunye neentanda zavela kwi-weld, kwaye izinga lokufaneleka lehla ngokukhawuleza. Emva kokuphucula inkqubo yonyango, izinga lokufaneleka linyuke laya kutsho ngaphezu kwe-95%.

2. Ukukhethwa kweParameters yeWelding efanelekileyo

Iiparamitha ze-welding ezifana namandla e-laser, isantya se-welding kunye nesikhundla sokugxila kubaluleke kakhulu. Kwiipleyiti ze-aluminium ezinobunzima be-2 - 3mm, amandla e-1500 - 1800W afanelekile ngakumbi; kulabo abanobunzima be-3 - 5mm, i-1800 - 2000W ifanelekile. Isantya se-welding kufuneka sihambelane namandla. Ngokomzekelo, xa amandla e-1800W, isantya se-5 - 7mm / s sifanelekile. Isikhundla ekugxilwe kuso sichaphazela umphumo we-welding. Ugxininiso lweepleyiti ezibhityileyo ziphezu komhlaba, ngelixa iipleyiti ezityebileyo, kufuneka zibe nzulu ngaphakathi.

3. Ukulawulwa kokuNgena koBushushu

I-aluminium yensimbi ine-conductivity ephezulu ye-thermal kwaye ixhomekeke ekulahlekeni kobushushu, echaphazela ukungena kwe-weld kunye namandla. Ulawulo oluchanekileyo lwegalelo lobushushu luyafuneka. Umzekelo, xa ishishini le-aerospace lidibanisa iinxalenye ze-aluminiyam, ukulawulwa kakubi kwegalelo lobushushu kukhokelele ekudibaneni okungaphelelanga kwe-weld. Ingxaki yasonjululwa emva kokuphucula inkqubo.

4. Ukusetyenziswa kweGesi yokuKhusela

Igesi efanelekileyo yokukhusela inokuthintela i-weld oxidation kunye ne-porosity. I-Argon, i-helium okanye imixube yazo isetyenziswa ngokuqhelekileyo, kwaye izinga lokuhamba kunye nolwalathiso lokuvuthela kufuneka lulungiswe ngokufanelekileyo. Uphando lubonisa ukuba i-argon flow rate ye-15 - 20 L / min kunye nolwalathiso olufanelekileyo lokuvuthela kunokunciphisa i-porosity.

Kwixesha elizayo, kulindeleke ukuba izixhobo zokuwelda i-laser ezingaphezulu kwamandla kunye nobukrelekrele ziya kuvela, kunye neenkqubo ezintsha zokuwelda kunye nezixhobo ziya kukhuthaza ukusetyenziswa kwayo okubanzi. Ukuqukumbela, kuphela ngokulandela la manyathelo okhuseleko, ukuqokelela amava kunye nokwandisa inkqubo apho okunokuthi kusetyenziswe izibonelelo ze-laser welding ukufaka isandla kuphuhliso loshishino lokuvelisa.
