Ubude owomileyo
Ukuhamba kwerhasi L=[(10-12)d] L/min
Ubude bocingo oluphuma emlonyeni wombhobho bubude obomileyo bobude. Ifomula yeempirical jikelele ili-10-15 umphinda-phinde ngocingo idiameter L = (10-15) d. Xa umgangatho mkhulu, uba mkhulu kancinci. Inkcazo incinci, incinci kancinci.
Ukolula ukolula ixesha elide kakhulu: Xa ubude bocingo lwe-welding buhamba ixesha elide, ubukhulu bobushushu bokumelana nocingo lwe-welding, ngokukhawuleza isantya sokunyibilika socingo lwe-welding, olunokubangela ukuba ucingo lwe-welding ludibanise kumacandelo, i-splash, inyibilika ubunzulu, kunye nokutsha kwe-arc engazinzanga. Ngexesha elifanayo, umphumo wokukhusela igesi awulungile.
Ukolula ukolula kufutshane kakhulu: kulula ukutshisa umbhobho wokuqhuba. Kwangaxeshanye, i-nozzle conductive kulula ukuyibamba ucingo xa ishushu. I-Splashes ivame ukuvala umlomo kwaye inyibilike kakhulu.
Itheyibhile 1 Ukuthelekisa ubudlelwane phakathi kobude obukhoyo nokomileyo
| Welding current (A) | ≤200A | 200-350A | 350-500A |
| Ubude owomileyo (mm) | 10-15mm | 15-20mm | 20-25mm |
Ukuhamba kwerhasi
Ukuhamba kwerhasi L=[(10-12)d] L/min
Inkulu kakhulu: idala isiphithiphithi, ibangela ukungena komoya kunye nemingxuma, ngakumbi kwizinto ezingeva ngegesi (ezinje ngealloyi ze-aluminiyam, iingxube ze-magnesium, njl., eziziimbobo zangaphakathi ngokubanzi)
Incinci kakhulu: ukukhuselwa kakubi kwegesi (ungabhekisela kwimiqathango eqingqiweyo, oku kuthetha ukuba akukho gesi ekhuselayo, kunye neepore ezimise okwe-honeycomb zilungele ukubonakala).
Isantya somoya asichaphazeleki xa ≤2m/s.
Kufuneka kuthathwe amanyathelo xa isantya somoya siku-≥2m/s.
① Ukunyusa izinga lokuhamba kwerhasi.
② Thatha amanyathelo angangeni moya.
Qaphela: Xa umoya uvuza, imingxuma yomoya iya kuvela kwi weld. Indawo yokuvuza komoya kufuneka iphathwe kwaye ayinakongezwa ngokunyusa izinga lokuhamba. Akukho ndlela yokulungisa imingxuma yomoya ngaphandle kokuyisusa. Iya kuba yi welding ngakumbi. ezininzi.
Amandla e-arc
Xa ubukhulu beplate eyahlukeneyo, izikhundla ezahlukeneyo, iinkcukacha ezahlukeneyo, kunye neengcingo ezahlukeneyo ze-welding, imikhosi eyahlukeneyo ye-arc ikhethiwe.
Inkulu kakhulu: i-arc eqinile, i-splash enkulu.
Incinci kakhulu: i-arc ethambileyo, i-splash encinci.
Amandla oxinzelelo
Kuqiniswe kakhulu: Intambo ye-welding ikhubazekile, i-wire feeding ayizinzanga, kwaye kulula ukubangela i-wire jams kunye nokwandisa ukutshiza.
Ukukhululeka kakhulu: Ucingo lokuwelda luyatyibilika, ucingo luthunyelwa kancinci, i-welding ayizinzanga, kwaye iya kubangela ukutshiza.
Okwangoku, i-voltage
Ifomula yobuchule yobudlelwane phakathi kwangoku kunye nombane we-welding ekhusela igesi: U=14+0.05I±2
I-welding current kufuneka ikhethwe ngokuchanekileyo ngokusekelwe kubukhulu bezinto ezisisiseko, ifom edibeneyo kunye nobubanzi bocingo. Ngexesha lenguqu yesiphaluka esifutshane, zama ukukhetha i-current encinci ngelixa uqinisekisa ukungena, kuba xa i-current ikhulu kakhulu, kulula ukubangela ukuba i-pool yokutshatyalaliswa iqhube, kungekhona nje ukutshiza okukhulu, kodwa ukubunjwa kubi kakhulu.
I-voltage ye-welding kufuneka yenze ulungelelwaniso olulungileyo kunye ne-current. I-voltage ye-welding iphezulu kakhulu okanye iphantsi kakhulu, eya kubangela ukutshiza. I-voltage ye-welding kufuneka inyuke ngokunyuka kwe-welding current kwaye kufuneka iyancipha ngokuhla kwe-welding current. Amandla ombane wokuwelda afanelekileyo aphakathi kwe-1-2V, ngoko ke amandla ombane wokuwelda kufuneka acocwe ngononophelo.
Umsinga mkhulu kakhulu: ubude be-arc bufutshane, i-splash inkulu, imvakalelo yesandla esiphezulu, ukuphakama okuseleyo kukhulu kakhulu, kwaye amacala amabini awadibanisi kakuhle.
I-voltage iphezulu kakhulu: i-arc inde, i-splash inkulu kancinci, ikhoyo ngoku ayizinzile, ukuphakama okuseleyo kuncinci, i-welding ibanzi, kwaye i-arc itshiswa ngokulula.
Iziphumo zesantya welding fast kwi welding
Isantya se-welding sinempembelelo ebalulekileyo kumgangatho wangaphakathi kunye nokubonakala kwe-weld. Xa i-voltage yangoku ingatshintshi:
Isantya se-welding sikhawuleza kakhulu: ubunzulu bokunyibilika, ububanzi bokunyibilika, kunye nokuphakama okushiyekileyo kuyancipha, ukwenza i-convex okanye i-hump welding bead, kwaye iinzwane ziluma inyama. Xa isantya se-welding sikhawuleza kakhulu, umphumo wokukhusela igesi uya konakaliswa kwaye iipores zenziwe lula.
Ngelo xesha, isantya sokupholisa i-welding metal iya kunyuswa ngokufanelekileyo, ngaloo ndlela inciphisa iplastiki kunye nokuqina kwentsimbi ye-welding. Kwakhona kuya kubangela ukuba umphetho ubonakale phakathi kwe-welding, okubangela ukubunjwa kakubi.
Isantya se-welding sicotha kakhulu: i-pool etyhidiweyo iba nkulu, i-bead ye-welding iba banzi, kwaye iinzwane ze-welding ziyaphuphuma. Irhasi ekwidama elinyibilikisiweyo ikhutshwa lula ngenxa yesantya esicothayo sokuwelda. Ulwakhiwo lwentsimbi yeweld lungqindilili okanye lutshiswe ngenxa yobushushu obugqithisileyo.
Xa ukhetha i-welding parameters, le miqathango ilandelayo kufuneka ilandelwe: i-weld inhle ngokubonakala kwaye ayinaziphene ezifana nokutshisa, i-undercuts, i-pores, i-cracks, njl. Ubunzulu bokunyibilika bulawulwa ngaphakathi koluhlu olufanelekileyo. Inkqubo ye-welding izinzile kwaye i-splash incinci. Kwavakala isandi esirhashazayo xa siwelding. Kwangaxeshanye, eyona mveliso iphezulu kufuneka iphunyezwe.
