Indlela yokulungelelanisa iiParameters kwi-CO2 Welding

Ukulungelelaniswa kweparameters zenkqubo ye-carbon dioxide gas shielded welding: Zininzi iiparameters zenkqubo ezichaphazela i-carbon dioxide gas shielded welding, kodwa ekuphela kwee-welders ezinokuzihlengahlengisa ngokwazo zi-welding voltage, i-welding current, i-wire diameter, i-gas flow rate, kunye nokwandiswa kwecingo. ubude; Amaxabiso okubhekisela kwiiparameters zenkqubo ye-welding: I-diameters yocingo esetyenziswa ngokuqhelekileyo yi-1.2mm kunye ne-1.0mm, ngaphezu kwe-1.6mm kunye ne-0.8mm. Kunzima ukudibana neengcingo ze-welding zezinye iidiameter. Ikharbhon dayoksayidi igesi ekhuselwe ukuwelda ithatha inguqu yesekethe emfutshane, ngoko ke indawo echaza ukuwelda kwidayamitha nganye yocingo lwewelding ibanzi. Kule ndawo, i-welding current kunye ne-welding voltage kufuneka ihambelane.

Inkqubo yokusebenza yokulungelelanisa iinkcukacha ze-welding: Lungisa i-current kunye ne-voltage yomshini we-welding ngokwenkqubo elandelayo;

1. Vula i-valve ye-cylinder valve yokukhusela kwaye uqinisekise ukuba uxinzelelo lwe-cylinder yegesi luqhelekileyo; Vula amandla omatshini we-welding kwaye uqinisekise ukuba i-flowmeter yokufudumala kunye nokunciphisa uxinzelelo iyasebenza; Ukushisa imizuzu emi-5;
2. Vula ukupakishwa kocingo lwe-welding, faka i-welding wire reel kwi-reel shaft yendlela yokutya yocingo, vula i-clamping handle, kwaye usebenzise iipliers ukusika intloko ye-welding kwi-flat head. Intloko yocingo lwe-welding kufuneka ifakwe ngokuthe tye kwivili le-groove ye-roller yokutya yocingo ukusuka ngaphantsi kwe-reel ye-welding wire; Faka umbhobho wokutyisa ucingo;
3. Vala i-clamping handle, beka i-welding gun phantsi kwaye uyandise ngokupheleleyo. Cinezela iqhosha elimhlophe lokutyisa ucingo olukhawulezayo kwibhokisi yolawulo olukude ukondla ucingo lwe welding lude luvezwe kumlomo wokuqhuba. Ukuba i-welding gun endala, unokususa kuqala i-nozzle conductive, uze ucinezele i-micro switch ukondla ucingo, uyiveze, kwaye uyibuyisele kwakhona; Sebenzisa iipliers ukusika isiphelo socingo lwe-welding kwi-angle ebukhali ye-45 degree;

4.Lungisa ipleyiti yentsimbi yokuvavanya, khangela ngokubonakalayo i-voltmeter kunye ne-ammeter yomatshini we-welding, yehlisa ngononophelo i-voltage kwibhokisi yokulawula kude ngesandla sakho sasekhohlo, ubambe umpu welding ngesandla sakho sokunene, kwaye uqalise i-arc welding kwintsimbi yokuvavanya. ipleyiti Ukuba i-voltage iphantsi ngokwenene, isandla sasekunene esibambe umpu siyakuva ukungcangcazela okunamandla kwentloko ye-welding gun kwaye sive isandi sokuphuma kwe-arc. Esi sisandi esenziweyo xa i-voltage iphantsi kakhulu, isantya sokutya kweengcingo sikhawuleza kakhulu kunesantya sokunyibilika, kwaye i-arc iyacinywa kwaye emva koko icinywe ngocingo lwe-welding; Ukuba i-voltage iphezulu kakhulu, i-arc inokuvutha, kodwa ukuba ubude be-arc bude kakhulu, ibhola enkulu etyhidiweyo iya kubumba ekupheleni kocingo lwe-welding. Ukuba isantya sokunyibilika sidlula isantya sokutya kocingo kakhulu, i-arc iya kuqhubeka ivutha umva kwi-nozzle conductive, inyibilika i-welding wire kunye ne-nozzle edibeneyo, iphelisa i-wire feeding, kunye nokucima i-arc. Oku kuya kubangela umonakalo kuzo zombini i-nozzle conductive kunye ne-wire feeding mechanism, ngoko kufuneka kuqinisekiswe ukuba i-voltage ayiphezulu kakhulu xa iqala i-arc;

5. Lungisa iqhosha le-welding voltage, ngokuthe ngcembe wonyuse i-voltage ye-welding, isantya sokunyibilika socingo lwe-welding, kunye nesandi esiqhekezayo sokwaphuka ngokuthe ngcembe sibe sisandi esigudileyo;
6. Jonga i-voltmeter kunye ne-ammeter. Ukuba i-current iphantsi kunexabiso elichazwe kwangaphambili, yandisa i-welding current kuqala kwaye yandise i-welding voltage; Ukuba i-current iphezulu kunexabiso elimiselweyo, okokuqala ukunciphisa i-voltage ye-welding, kwaye unciphise i-welding current;
7. Ubude bokwandiswa kocingo lwe-welding: ekwaziwa njengobude owomileyo bolwandiso locingo lwe-welding. Kwi-welding ekhuselekileyo yegesi, iparameter ebaluleke kakhulu. Ubude obufanelekileyo bokwandiswa kocingo lwe-welding lunokubonelela ngokwaneleyo ukufudumeza ukuxhathisa, okwenza kube lula ukwenza kunye nokutshintsha amaconsi atyhidiweyo ekupheleni kocingo lwe-welding. Xa ubude bokwandiswa kocingo lwe-welding bufutshane kakhulu, kudla ngokubakho ukutshiza. Ukuba mde kakhulu akuvelisi ngokulula ukutshiza kwamathontsi amakhulu, kodwa kukhokelela kukhuseleko olulambathayo.
8. I-Phenomenon xa i-welding voltage kunye ne-welding current ihambelana: i-arc iyavutha ngokuthe ngcembe, ikhupha isandi esihle, i-welding gun intloko ishukuma kancinci, ubunzima buphakathi, i-voltmeter swing ayidluli i-5V, i-ammeter swing ayidluli kwi-30A, kwaye kufuneka kungabikho kungcangcazela ekubambeni kwesandla; Ukuba intloko ye-welding gun ivakalelwa kakhulu kwaye akukho nto ishukumayo, umpu we-welding unokushukunyiswa ngokukhululekileyo. Ngokujonga imaski yobuso, ucingo lokuwelda ludada ngaphezulu kwedama elinyibilikisiweyo, lenze ibhola enkulu etyhidiweyo ekugqibeleni, kwaye ngamanye amaxesha amathontsi amakhulu atshizayo, ebonisa ukuba umbane uphezulu kakhulu; Ukuba intloko ye-welding gun ivakalelwa kakhulu kwaye ishukuma kakhulu, isandi esiphumayo sinokuvakala, kwaye kukho ukuchasana xa uhambisa i-welding gun. Ngokujonga imaski yobuso, ukuba i-welding wire ifakwe kwi-pool etyhidiweyo kwaye iqhume ngaphezulu, ibonisa ukuba i-voltage iphantsi; Kuyinzuzo ukuba namandla ombane aphezulu kancinci ukuthintela ukudityaniswa okungaphelelanga.
9. I-gas shielded welding with melting electrode, ukulungiswa kwe-welding current kukulungelelanisa isantya sokutya kocingo lwe-welding wire, kunye nokulungelelaniswa kwe-welding voltage kukulungelelanisa isantya sokunyibilika kocingo lwe-welding. Xa isantya sokutya kocingo kunye nesantya sokunyibilika silingana, i-arc iyatshisa ngokuzinzileyo.
