Ukukhetha Ngokufanelekileyo iGesi yoKhuseleko — Isitshixo sokuphucula umgangatho wokuWelda kunye nokwandisa ubomi benkonzo yezixhobo

Kwi-laser welding, ukhetho olufanelekileyo lwegesi yokukhusela yenye yezona zinto zibalulekileyo ezimisela umgangatho we-welding. Igesi yokukhusela ayiphuculi nje kuphela ukuguda komphezulu we-weld kwaye inciphisa i-oxidation ebangelwa kukudibana.

phakathi kwechibi elinyibilikisiweyo nomoya ojikeleze umhlaba, kodwa ikwanciphisa kakhulu ungcoliseko lwelensi, ikhusela indlela yangaphakathi yokukhanya yomatshini wokuwelda, kwaye yandisa ubomi benkonzo yesixhobo.Umatshini wokuwelda we-laser ophathwayo

Iziphumo zinxulumene kakhulu nokukhetha igesi—eli nyathelo libalulekileyo akufuneki lijongwe.

Imisebenzi yeGesi yokukhusela

Uthintelo Lokuqala Lokungcoliswa Kwe-Oxidation Nokungcoliswa:Iyawahlula ichibi elinyibilikisiweyo kwaye iwashisele emoyeni kwindawo yokuwelda enobushushu obuphezulu, ithintela i-oxidation kunye nokufunxwa kokungcola.

Uphuculo lwesibini lokwenziwa kweWeld:Inciphisa ukuchitheka kwaye iphucula ukuguda kwe-weld, ukufana, kunye nenkangeleko.

Ukhuseleko Lomoya Ongangenisi Nto: Ngokudala imeko-bume engangenisi nto ejikeleze indawo yokuwelda, ukhuseleko lwegesi ludlala indima ebalulekileyo koku:

Ukuthintela okwesithathu ukuphazamiseka komoya:Ithintela ngempumelelo ioksijini, initrogen, kunye nokufuma emoyeni ekungasabelani nedama elinyibilikisiweyo elinobushushu obuphezulu, ithintela ukubola, ukufakwa kwe-oxidation, kunye nezinye izinto.

iziphene.

Izixhobo Zesine Ezikhuselayo:Inciphisa ungcoliseko olusasazwayo kwilensi yesibhamu sokuwelda, inciphisa umngcipheko wokuwohloka kwendlela ye-optical okubangelwa yi-oxidation okanye i-corrosion, kwaye yandisa amaxesha okugcinwa.

Iingcebiso eziqhelekileyo zeGesi yokukhusela

I-Argon

Njengegesi engasebenziyo esetyenziswa kakhulu ekudibaniseni, i-argon inika uzinzo oluhle kakhulu lweekhemikhali kunye nokukwazi ukuxhasa i-arc. Uxinano lwayo oluphezulu luyivumela ukuba yenze umaleko ozinzileyo wokugubungela phezu kwechibi elinyibilikisiweyo, ivelise ubuhle obuhle.

iyathandeka ileza izixhobo zokuweldaIfanelekile ngokukodwa kwiintsimbi ezithambekele ekufakweni kwe-oxidation ezifana nentsimbi engagqwaliyo, ii-aluminium alloys, kunye nee-titanium alloys.

I-nitrogen

Kwizinto ezifana nentsimbi ethambileyo kunye nentsimbi engenamthungo, i-nitrogen lukhetho olungabizi kakhulu, olunika ukungangeni kakuhle okuphakathi kunye neenzuzo zoqoqosho. Kwezinye iintsimbi, inokuphucula ubulukhuni bomphezulu, kodwa kumaqondo obushushu aphezulu, isenokuba

sabela ngesinyithi esisisiseko. Ukufaneleka kufanele kuhlolwe ngokusekelwe kwiimfuno ezithile zenkqubo.

I-Helium

IHelium igqwesile kwizicelo zokuwelda ezinobunzima obuphezulu, ezifana nokuwelda ithusi kunye nee-alloys zobhedu. Ukuqhuba kwayo okuphezulu kobushushu kwenza ukuba ingene nzulu, yoyise umngeni obangelwa kubushushu obuphezulu bethusi.

ukusasazwa, ngelixa kunciphisa ukutshintsha kombala we-weld oxidation. Ngenxa yexabiso layo eliphezulu, i-helium idla ngokugcinelwa ukusetyenziswa okukhethekileyo, okufunwa kakhulu.

Ubunyulu kunye namanyathelo okhuseleko

Ucoceko lweGesi: Sebenzisa iigesi ezicocekileyo kakhulu (≥ 99.99%) ukuqinisekisa ukusebenza kakuhle kokuwelda kunye nomgangatho ophezulu wokuwelda. Nokuba zincinci kangakanani na izinto ezingcolisayo zinokubangela iziphene ezinkulu ezifana nokuqhekeka kunye nokuqhekeka.

Iigesi Ezingavumelekanga: Iigesi ezixutyiweyo, ikharbon diokside, kunye neoksijini mazithintelwe ngokungqongqo, njengoko zinokukhokelela kwi-weld oxidation, ukwanda kwe-porosity, kwanokonakalisa inkqubo ye-optical.

Isiphelo:

Ukukhetha nokusebenzisa igesi yokukhusela efanelekileyo akupheleli nje ekuphuculeniUmatshini wokuwelda we-laser onama-4 kwi-1inkangeleko kunye namandla kodwa kunciphisa iindleko zokulungisa kwaye kwandisa ubomi bezixhobo. Yinto ebalulekileyo ekuqinisekiseni

imisebenzi yokuwelda nge-laser esebenza kakuhle kakhulu nezinzileyo.
