1. Txheej txheem txheej txheem
Electrode arc welding yog ib qho kev siv vuam arc uas siv lub vuam pas nrig.Lub cim cim E rau electrode arc vuam thiab cov lej cim 111.
Cov txheej txheem vuam ntawm electrode arc vuam: thaum vuam, vuam pas nrig yog coj mus rau hauv kev sib cuag nrog lub workpiece tam sim ntawd tom qab luv luv Circuit Court, igniting lub arc.Lub siab kub ntawm lub arc ib nrab melts lub electrode thiab lub workpiece, thiab lub melted core hloov mus rau ib nrab melted workpiece nto nyob rau hauv daim ntawv ntawm ib tug molten poob, uas yog fused ua ke los tsim ib tug molten pas dej ua ke.Lub vuam electrode flux ua rau qee qhov roj thiab kua slag thaum lub sij hawm melting txheej txheem, thiab cov roj uas ua los ntawm cov arc thiab cov cheeb tsam ib puag ncig ntawm lub pas dej molten, ua lub luag haujlwm ntawm kev cais cov huab cua los tiv thaiv cov kua hlau.Cov kua slag ceev yog me me, nyob rau hauv lub melt pas dej ua ke tas li floating, them rau cov kua hlau saum toj no, los tiv thaiv lub luag hauj lwm ntawm cov kua hlau.Nyob rau tib lub sij hawm, lub flux daim tawv nqaij melting gas, slag thiab melting lub weld core, lub workpiece ib tug series ntawm metallurgical tshuaj los xyuas kom meej qhov kev ua tau zoo ntawm lub weld tsim.
2. Qhov zoo ntawm electrode arc vuam
1) Cov khoom siv yooj yim, kev saib xyuas yooj yim.AC thiab DC vuam tshuab siv rau electrode arc vuam yog qhov yooj yim thiab tsis xav tau cov cuab yeej pabcuam nyuaj rau kev ua haujlwm ntawm vuam pas nrig, thiab tsuas yog yuav tsum tau nruab nrog cov cuab yeej pabcuam yooj yim.Cov tshuab vuam no yooj yim hauv cov qauv, pheej yig thiab yooj yim los tswj, thiab kev nqis peev hauv kev yuav khoom siv tsawg, uas yog ib qho laj thawj rau nws daim ntawv thov dav.
2) Tsis tas yuav tsum muaj kev tiv thaiv roj, lub vuam pas nrig tsis yog tsuas yog muab cov hlau muab tub lim, tab sis kuj tseem tuaj yeem tsim cov roj tiv thaiv los tiv thaiv lub pas dej molten thiab cov vuam los ntawm oxidation thaum lub sij hawm vuam, thiab muaj cov cua kub tshwj xeeb.
3) Kev ua haujlwm yooj yim thiab muaj zog yoog raws.Stick arc vuam yog tsim rau welding ib daim los yog cov khoom me me ntawm cov khoom, luv luv thiab tsis xwm yeem, arbitrarily nyob rau hauv qhov chaw thiab lwm yam vuam seams uas tsis yooj yim mus cuag mechanized vuam.Vuam tuaj yeem nqa tawm txhua qhov chaw uas lub vuam pas nrig tuaj yeem ncav cuag, nrog kev nkag tau zoo thiab ua haujlwm yooj yim heev.
4) Kev siv ntau yam, haum rau vuam feem ntau muaj hlau thiab alloys.Xaiv txoj hlua vuam zoo tuaj yeem tsis tsuas yog vuam cov hlau, cov hlau tsis tshua muaj hlau, tab sis kuj muaj cov hlau alloy siab thiab cov hlau tsis muaj hlau;Tsis tsuas yog tuaj yeem welding tib cov hlau, tab sis kuj tuaj yeem sib txawv ntawm cov hlau sib txawv, tab sis kuj tseem tuaj yeem kho cov hlau welding thiab ntau yam khoom siv hlau xws li overlay welding.
3. qhov tsis zoo ntawm electrode arc vuam
1) welders kev khiav hauj lwm technology yuav tsum muaj siab, cov welder kev cob qhia cov nqi.Vuam zoo ntawm electrode arc vuam nyob rau hauv tas li ntawd mus rau kev xaiv ntawm haum vuam electrodes, vuam txheej txheem tsis thiab vuam cov cuab yeej, feem ntau yog los ntawm cov welder kev khiav hauj lwm cov tswv yim thiab kev paub los xyuas kom meej tias cov vuam zoo ntawm electrode arc vuam rau ib tug tej yam kev txiav txim los ntawm cov welder kev khiav hauj lwm. cov txheej txheem.Yog li ntawd, welders yuav tsum tau kawm ntau zaus, cov nqi kawm yuav tsum tau loj.
2) Kev ua haujlwm tsis zoo.Stick arc welding feem ntau yog nyob ntawm kev ua haujlwm ntawm cov welder thiab kev soj ntsuam qhov muag kom tiav cov txheej txheem, cov vuam siv zog.Thiab ib txwm nyob rau hauv qhov kub thiab txias fume ib puag ncig, kev ua haujlwm tsis zoo, yog li txhawm rau txhim kho kev tiv thaiv kev ua haujlwm.
3) Tsawg ntau lawm efficiency.Vuam pas nrig arc vuam feem ntau yog nyob ntawm kev ua haujlwm ntawm phau ntawv, thiab cov txheej txheem vuam txheej txheem los xaiv ntau yam me me.Tsis tas li ntawd, vuam electrode yuav tsum tau hloov tsis tu ncua, thiab vuam channel slag tu yuav tsum tau nqa tawm tsis tu ncua, piv nrog tsis siv neeg vuam, vuam productivity yog tsawg.
4) Tsis siv rau cov hlau tshwj xeeb thiab nyias phaj vuam.Rau cov hlau nquag thiab cov hlau tsis muaj dej, vim tias cov hlau no muaj kev cuam tshuam rau cov pa phem, kev tiv thaiv ntawm electrode tsis txaus los tiv thaiv oxidation ntawm cov hlau, kev tiv thaiv cov nyhuv tsis zoo txaus, qhov vuam zoo tsis ua raws li qhov yuav tsum tau ua, yog li koj tsis tuaj yeem siv electrode arc vuam.Tsawg melting point hlau thiab lawv cov alloys tsis tuaj yeem welded los ntawm electrode arc vuam vim qhov kub ntawm qhov arc siab dhau rau lawv.
4. Daim ntawv thov ntau yam
1) Muaj feem xyuam rau txhua txoj haujlwm vuam, workpiece thickness saum 3 hli
2) Weldable hlau ntau: hlau uas tuaj yeem welded muaj xws li carbon steel, tsis tshua muaj hlau alloy, stainless hlau, kub resistant steel, tooj liab thiab nws alloys;hlau uas tuaj yeem welded tab sis tej zaum yuav preheated, tom qab cua sov los yog ob qho tib si xws li cam khwb cia hlau, siab zog steel, quenched steel, thiab lwm yam.;Tsawg melting point hlau uas tsis tuaj yeem welded xws li Zn / Pb / Sn thiab nws cov alloys, insoluble hlau xws li Ti / Nb / Zr, thiab lwm yam.
3) Cov khoom tsim nyog tshaj plaws thiab cov xwm txheej ntawm kev tsim khoom: cov khoom siv nrog cov qauv tsim, nrog rau ntau txoj haujlwm spatial, welds uas tsis yooj yim los yog automated;ib leeg-nqi los yog tsawg-ntim welded khoom thiab installation los yog kho departments.
