Iindidi ezahlukeneyo zegesi yoKhuselo
Iigesi ezisetyenziswa ngokuqhelekileyo kwi-laser welding yi-nitrogen (N2), i-argon (Ar), kunye ne-helium (He). Ezi gesi zineempawu ezahlukeneyo zomzimba kunye neekhemikhali, ezikhokelela kwiimpembelelo ezahlukeneyo kwi-weld seam.
1. Initrogen (N2)
I-N2 inamandla e-ionization aphakathi, aphezulu kuneAr kwaye aphantsi kunoYe. Ngaphantsi kwesenzo se-laser, i-ionize kwiqondo eliphakathi, ukunciphisa ngokufanelekileyo ukubunjwa kwamafu e-plasma kunye nokwandisa ukusetyenziswa kwe-laser. Nangona kunjalo, i-nitrogen inokusabela kwimichiza kunye ne-aluminium alloys kunye ne-carbon steel kumaqondo obushushu athile, yenze i-nitrides. Oku kunokunyusa i-brittleness kunye nokunciphisa ukuqina kwe-weld seam, echaphazela kakubi iimpawu zayo zomatshini. Ngoko ke, ukusetyenziswa kwe-nitrogen njengegesi ekhuselayo ye-aluminium alloys kunye ne-carbon steel welds ayikhuthazwa. Kwelinye icala, initrogen inokusabela ngentsimbi engatyiwayo, yenze i-nitrides eyomeleza amandla entsimbi ye-weld. Ke ngoko, initrogen ingasetyenziswa njengerhasi ekhuselayo yokuwelda intsimbi engatyiwayo.
2. Irhasi yeArgon (Ar)
Irhasi yeArgon inawona mandla asezantsi e-ionization, okukhokelela kwinqanaba eliphezulu le-ionization phantsi kwesenzo se-laser. Oku kungathandekiyo ekulawuleni ukubunjwa kwamafu eplasma kwaye kunokuba nefuthe elithile ekusebenziseni ngokufanelekileyo iilaser. Nangona kunjalo, i-argon ine-reactivity ephantsi kakhulu kwaye ayinakwenzeka ukuba ingene kwi-chemical reactions kunye neentsimbi eziqhelekileyo. Ukongezelela, i-argon inexabiso elisebenzayo. Ngaphaya koko, ngenxa yokuxinana kwayo okuphezulu, i-argon izika ngaphezulu kwe-weld pool, inika ukhuseleko olungcono lwe-weld pool. Ngoko ke, inokusetyenziswa njengegesi eqhelekileyo yokukhusela.

Ngokuqhelekileyo isetyenziswa kuphando lwezenzululwazi okanye kwiimveliso eziphezulu zexabiso elongezelelweyo.
Iindlela ezimbini zokuSebenzisa igesi yoKhuselo
Okwangoku, kukho iindlela ezimbini eziphambili zokwazisa igesi ekhuselayo: ukuvuthela ecaleni kwe-axis kunye ne-coaxial shielding gas, njengoko kubonisiwe kuMfanekiso 1 kunye noMfanekiso 2, ngokulandelanayo.
Umzobo 1: Irhasi yoKhuseleko lweGasi esecaleni kwi-Off-axis
Umzobo 2: Igesi yeCoaxial Shielding
Ukhetho phakathi kweendlela ezimbini zokuvuthela kuxhomekeke kwiingcamango ezahlukeneyo.
Ngokubanzi, kuyacetyiswa ukuba kusetyenziswe indlela yokuvuthela ecaleni kwe-off-axis ukukhusela irhasi.
Indlela yokukhetha igesi efanelekileyo yoKhuseleko?
Okokuqala, kubalulekile ukucacisa ukuba igama elithi "i-oxidation" ye-welds yintetho ye-colloquial. Ngokwethiyori, ibhekisa ekuwohlokeni komgangatho we-weld ngenxa yokusabela kweekhemikhali phakathi kwentsimbi ye-weld kunye nezinto ezinobungozi emoyeni, njengeoksijini, initrogen, kunye nehydrogen.
Ukuthintela i-weld oxidation kubandakanya ukunciphisa okanye ukuphepha ukudibanisa phakathi kwezi zixhobo ezinobungozi kunye nentsimbi ye-weld ephezulu. Lo mgangatho wobushushu obuphezulu awubandakanyi kuphela isinyithi esityhidiweyo sechibi kodwa kunye nexesha lonke ukusuka xa intsimbi ye-weld inyibilika de i-pool iqina kwaye ubushushu bayo buyancipha ngaphantsi komqobo othile.
Inkqubo yeWelding
Ngokomzekelo, kwi-welding ye-titanium alloys, xa izinga lokushisa lingaphezulu kwe-300 ° C, ukuxutywa kwe-hydrogen ngokukhawuleza kwenzeka; ngaphezu kwe-450 ° C, ukufunxa oksijini ngokukhawuleza kwenzeka; kwaye ngaphezu kwe-600 ° C, ukufunxa ngokukhawuleza kwenitrogen kwenzeka.
Ngoko ke, ukukhuselwa okusebenzayo kuyadingeka kwi-titanium alloy weld ngexesha lesigaba xa liqina kwaye izinga lokushisa liyancipha ngaphantsi kwe-300 ° C ukukhusela i-oxidation. Ngokusekelwe kwinkcazo engentla apha, kuyacaca ukuba i-gas ekhuselayo evuthelweyo idinga ukubonelela ngokhuseleko kungekhona kuphela kwi-weld pool ngexesha elifanelekileyo kodwa nakwindawo eqinisiweyo nje ye-weld. Ngenxa yoko, indlela yokuvuthela ecaleni kwe-off-axis eboniswe kuMzobo we-1 ngokuqhelekileyo ikhethwa ngenxa yokuba inika uluhlu olubanzi lokukhusela xa kuthelekiswa nendlela yokukhusela i-coaxial eboniswe kuMfanekiso 2, ngokukodwa kwingingqi eqinile nje ye-weld.
Nangona kunjalo, kwiimveliso ezithile ezithile, ukhetho lwendlela kufuneka lwenziwe ngokusekelwe kwisakhiwo semveliso kunye nokucwangciswa ngokubambisana.
