Ukunwebeka okomile
Ukugeleza kwegesi L=[(10-12)d] L/min
Ubude bocingo oluphuma ngomlomo wombhobho wokuqondisa ubude obomile bobude. Ifomula evamile ye-empirical izikhathi ezingu-10-15 kunobubanzi bocingo L = (10-15) d. Uma izinga likhulu, liba likhudlwana. Ukucaciswa kuncane, kuncane kancane.
Ukwelula okomile isikhathi eside kakhulu: Uma ubude bentambo yokushisela buba bude kakhulu, kuba mkhulu ukushisa kokumelana kwentambo yokushisela, isivinini sokuncibilika socingo lokushisela sishesha, esingabangela kalula ukuthi intambo yokushisela ihlangane ezingxenyeni, i-splash, ukujula kokuncibilika, kanye nokuvutha kwe-arc okungazinzile. Ngesikhathi esifanayo, umphumela wokuvikela igesi awumuhle.
Ukwelula okomile kufushane kakhulu: kulula ukushisa umlomo wombhobho. Ngasikhathi sinye, i-nozzle ye-conductive kulula ukubopha ucingo lapho ishisa. Ama-Splashes avame ukuvala umlomo wombhobho futhi ancibilike kakhulu.
Ithebula 1 Ukuqhathanisa ubudlelwano phakathi kobude bamanje nokomile
| I-Welding current (A) | ≤200A | 200-350A | 350-500A |
| Ubude bomile (mm) | 10-15 mm | 15-20 mm | 20-25 mm |
Ukugeleza kwegesi
Ukugeleza kwegesi L=[(10-12)d] L/min
Inkulu kakhulu: idala isiphithiphithi, ibangele ukungena komoya nezimbotshana, ikakhulukazi ezintweni ezizwela igesi (njengama-alloys e-aluminium, ama-alloys e-magnesium, njll., ngokuvamile okuyizimbotshana zangaphakathi)
Kuncane kakhulu: ukuvikelwa kwegesi okungalungile (ungabhekisela ezimweni ezilinganiselwe, okusho ukuthi ayikho igesi yokuvikela, futhi izimbotshana ezimise okwekhekheba lezinyosi zivame ukubonakala).
Isivinini somoya asithinteki uma ≤2m/s.
Izinyathelo kufanele zithathwe uma isivinini somoya siku-≥2m/s.
① Khulisa izinga lokugeleza kwegesi.
② Thatha izinyathelo zokuvikela umoya.
Qaphela: Uma kuvuza komoya, izimbobo zomoya zizovela endaweni yokushisela. Iphuzu lokuvuza komoya kufanele liphathwe futhi alikwazi ukwengezwa ngokukhuphula izinga lokugeleza. Ayikho indlela yokulungisa izimbobo zomoya ngaphandle kokuzikhipha. Izoba ashiselwe kakhulu. abaningi.
Amandla e-arc
Lapho ubukhulu bepuleti elihlukene, izikhundla ezihlukene, ukucaciswa okuhlukene, nezintambo zokushisela ezihlukene, amandla ahlukene e-arc akhethwa.
Kukhulu kakhulu: i-arc eqinile, i-splash enkulu.
Incane kakhulu: i-arc ethambile, i-splash encane.
Amandla okucindezela
Iqine kakhulu: Intambo yokushisela ikhubazekile, ukuphakelwa kwezintambo akuzinzile, futhi kulula ukubangela ukuxhuma kwezintambo nokwandisa ukuchaphaza.
Ukuxega kakhulu: Intambo yokushisela iyashelela, intambo ithunyelwa kancane, i-welding ayizinzi, futhi izodala ukuchaphazeka.
Okwamanje, i-voltage
Ifomula enamandla yobudlelwano phakathi kwamanje kanye ne-voltage ye-welding evikela igesi: U=14+0.05I±2
I-welding current kufanele ikhethwe ngokufanele ngokusekelwe ebukhulu bezinto eziyisisekelo, ifomu elihlangene kanye nobubanzi bocingo. Ngesikhathi sokushintsha kwesifunda esifushane, zama ukukhetha i-current encane ngenkathi uqinisekisa ukungena, ngoba lapho i-current ikhulu kakhulu, kulula ukubangela ukuba i-pool yokuchithwa igoqe, hhayi nje ukuthi iqhume kakhulu, kodwa ukubunjwa nakho kumpofu kakhulu.
I-voltage ye-welding kumele yakhe ukusebenzisana okuhle ne-current. I-voltage yokushisela iphezulu kakhulu noma iphansi kakhulu, okuzodala ukuchaphazeka. I-voltage ye-welding kufanele ikhule ngokunyuka kwe-welding current futhi kufanele yehle ngokuncipha kwe-welding current. I-voltage yokushisela efanele ngokuvamile iphakathi kwe-1-2V, ngakho-ke i-voltage yokushisela kufanele isuswe ngokucophelela.
I-current likhulu kakhulu: ubude be-arc bufushane, i-splash inkulu, umuzwa wesandla esiphezulu, ukuphakama okusele kukhulu kakhulu, futhi izinhlangothi ezimbili azihlanganisiwe kahle.
I-voltage iphezulu kakhulu: i-arc yinde, i-splash inkulu kancane, yamanje ayizinzile, ukuphakama okusele kuncane kakhulu, i-welding ibanzi, futhi i-arc iyashiswa kalula.
Imiphumela yejubane lokushisela elisheshayo ekushiseleni
Ijubane lokushisela linomthelela obalulekile kwikhwalithi yangaphakathi nokubukeka kwe-weld. Uma i-voltage yamanje ingashintshi:
Isivinini sokushisela siyashesha kakhulu: ukujula kokuncibilika, ububanzi bokuncibilika, nokuphakama okuyinsalela kuyancishiswa, kwakheka ubuhlalu be-convex noma i-hump welding, futhi izinzwane ziluma inyama. Uma isivinini sokushisela sishesha kakhulu, umphumela wokuvikela igesi uzolimala futhi ama-pores akhiqizwa kalula.
Ngasikhathi sinye, ijubane lokupholisa lensimbi yokushisela lizosheshiswa ngokufanele, ngaleyo ndlela kuncishiswe ipulasitiki nokuqina kwensimbi yokushisela. Kuzophinde kubangele ukuthi kuvele unqenqema phakathi kwe-welding, okuholela ekubumbeni okubi.
Ijubane lokushisela lihamba kancane: ichibi elincibilikisiwe liba likhulu, ubuhlalu bokushisela buba banzi, futhi izinzwane zokushisela ziyachichima. Igesi echibini elincibilikisiwe liphuma kalula ngenxa yejubane eliphansi lokushisela. Isakhiwo sensimbi se-weld siwugqinsi noma sishiswe ngenxa yokushisa ngokweqile.
Uma ukhetha imingcele yokushisela, kufanele kulandelwe izimo ezilandelayo: i-weld inhle ngokubukeka futhi ayinakho ukukhubazeka okufana nokuvutha, ama-undercuts, ama-pores, imifantu, njll. Ukujula kokuncibilika kulawulwa ngaphakathi kwebanga elifanele. Inqubo yokushisela izinzile futhi i-splash incane. Kuzwakale umsindo ohholozayo ngenkathi sishisela. Ngesikhathi esifanayo, ukukhiqiza okuphezulu kufanele kufinyelelwe.
