Izinto eziluncedo kunye nezingeloncedo zeLaser Welding yeAluminiyam Alloy
Xa i-laser welding aluminiyam ialloy, njengokuba i-welding ye-galvanized steel plate, iipores ezininzi kunye neentanda ziya kuveliswa ngexesha lenkqubo ye-welding, eya kuchaphazela umgangatho we-welding.I-aluminiyam inamandla aphantsi e-ionization, ukuzinza okungahambi kakuhle kwe-welding, kwaye kuya kubangela ukuyeka ukuwelda.Ukongeza kwindlela yokushisa ubushushu obuphezulu, i-aluminium oxide kunye ne-aluminium nitride iya kuveliswa kuyo yonke inkqubo, ibangele ukungcoliseka kwendalo.
Nangona kunjalo, umphezulu we-aluminiyam iplate ye-alloy inokugudiswa phambi kokuba i-welding yandise ukufunxa kwayo amandla e-laser;Irhasi ye-inert iya kusetyenziswa ngexesha le-welding ukukhusela imingxuma yomoya.
I-laser arc hybrid welding ye-aluminium alloy isombulule iingxaki zamandla we-laser welding, ukufunxwa kwe-laser beam kumphezulu we-aluminium alloy kunye nexabiso lomgubasi we-welding yokungena enzulu.Yenye yezona nkqubo zithembisayo ze-aluminium alloy welding.Okwangoku, inkqubo ayikavuthwa kwaye ikwinqanaba lophando kunye nokuhlola.
Ubunzima be-laser welding buhluke kwii-alloys ezahlukeneyo ze-aluminium.Unyango non ubushushu bomelezwa aluminiyam kunye aluminium ingxubevange 1000 series, 3000 series kunye 5000 series babe weldability elungileyo;I-4000 series alloy ine-crack sensitivity ephantsi kakhulu;Kwi-5000 series alloy, xa ω Xa (Mg) = 2%, i-alloy ivelisa iintanda.Ngokunyuka komxholo we-magnesium, ukusebenza kwe-welding kuphuculwe, kodwa i-ductility kunye ne-corrosion resistant iba yimbi;I-2000 series, 6000 series kunye ne-7000 series alloys zinomkhwa omkhulu wokuqhekeka okutshisayo, ukubunjwa okungahambi kakuhle kwe-weld, kunye nokunciphisa okubalulekileyo kwi-post weld eguga.
Ke ngoko, kwi-laser welding ye-aluminium alloy, kuyimfuneko ukuthatha amanyathelo afanelekileyo enkqubo kwaye ukhethe ngokuchanekileyo iindlela kunye neenkqubo ze-welding zokufumana iziphumo ezilungileyo.Ngaphambi kwe-welding, unyango olungaphezulu lwezinto eziphathekayo, ulawulo lweeparamitha zenkqubo ye-welding kunye nokutshintsha kwesakhiwo se-welding zonke iindlela ezisebenzayo.
Ukukhethwa kweeparamitha ze-welding
· Amandla eLaser 3KW.
· Isantya se-laser welding: 4m / min.Isantya se-welding sixhomekeke kubuninzi bamandla.Ukuphakama koxinano lwamandla, ngokukhawuleza isantya se-welding.
· Xa ipleyiti ifakwe igalvanized (efana ne-0.8mm yodonga lwangaphandle lwecala kunye ne-0.75mm kwipleyiti yangaphandle yesigqubuthelo), ukukhutshwa kwendibano kulawulwa ngumbindi, ngokubanzi 0.05 ~ 0.20mm.Xa i-weld ingaphantsi kwe-0.15 mm, umphunga we-zinc awukwazi ukususwa kwi-gap yecala, kodwa ususwe kwi-weld surface, elula ukuvelisa iziphene ze-porosity;Xa ububanzi be-weld bukhulu kune-0.15 mm, isinyithi esityhidiweyo asikwazi ukuzalisa ngokupheleleyo i-gap, okubangelwa amandla anganeleyo.Xa ubukhulu be-weld bufana ne-plate, iipropati zomatshini zizona zilungileyo, kwaye ububanzi be-weld buxhomekeke kububanzi obugxilwe;Ubunzulu be-weld buxhomekeke kubuninzi bamandla, isantya se-welding kunye nobukhulu bokugxila.
· Igesi yokukhusela i-argon, ukuhamba kwe-25L / min, kunye noxinzelelo lokusebenza ngu-0.15 ~ 0.20MPa.
· Ujoliso lwedayamitha 0.6 mm.
· Isikhundla sokugxila: xa ubukhulu beplate buyi-1mm, ingqwalasela ingaphezulu nje, kwaye indawo ekugxilwe kuyo ixhomekeke kwimilo yekhoni.
