Nyob rau hauv vuam terminology, "eleve pas nrig" thiab "electrode" feem ntau siv sib tham hauv kev sib tham sib txawv, tab sis technically, lawv tsis yog tib yam. Thaum muaj kev sib tshooj nyob rau hauv lawv lub luag haujlwm hauv qee cov txheej txheem vuam, lawv cov lus txhais, scopes ntawm daim ntawv thov, thiab cov haujlwm sib txawv. Nkag siab txog qhov kev sib txawv yuav pab zam kev tsis meej pem hauv kev ua haujlwm thiab kev sib txuas lus.
Dab tsi yog vuam pas nrig?
Ib lub vuam qws feem ntau yog hais txog cov neeg siv cov khoom siv uas siv tau siv hauv vuam. Nws lub luag haujlwm tseem ceeb yog kom yaj rau hauv Weld pas dej thaum vuam, sib koom ua ke nrog cov hlau sib koom ua ke. Feem ntau, vuam pas nrig yog tsim rau txoj kev vuam, xws li tus pas hluav taws xob siv hauv cov thaiv hlau arc vuam (smaw). Cov pas nrig no muaj cov hlau txheem thiab txheej txheem: cov tub ntxhais hluas ua raws li cov muab tub lim, thaum tsim cov roj lossis cov nyom) thiab tso cov arc. Txawm li cas los xij, tsis yog txhua lub pas nrig vuam yog siv los ua cov electrodes {}}} roj kub vuam, thiab cov pas dej ua ke ntau dua li hluav taws xob arc, thiab tus pas dej tsis ua hluav taws xob.
Dab tsi yog electrode?
Ib qho electrode yog ib qho tivthaiv uas coj hluav taws xob los tsim cov arc lossis tam sim no hauv kev vuam Circuit Court. Nws cov haujlwm tseem ceeb yog los pab hloov chaw hloov hluav taws xob, uas tsim lub siab kub xav tau kom yaj lub hauv paus hlau thiab muab tub lim (yog siv). Cov hluav taws xob yuav siv tau lossis tsis - consumable:
Cov ntawv siv hluav taws xob, xws li cov hluav taws xob lo rau hauv smaw lossis flux {{} Cored arc vuam (FCAW Hauv qhov no, lawv yog qhov tseem ceeb tib yam li vuam pas nrig.
Tsis -}} Cov Khoom Siv Hauv Cov Hluav Taws Xob, xws li Tungsten Electrodes hauv Roj Tungsten Arc Vuam (GTTT / TIG), lossis yaj tsawg dua) thaum vuam. Lawv tsuas yog coj hluav taws xob los tsim cov arc thiab tsis ua raws li cter-}}}}}}}}}} Kev tub rog vuam nyob hauv Tig vuam yog xav tau.
Qhov sib tshooj: Thaum lawv zoo ib yam
Hauv daim tawv hlau hlau arc vuam (smaw), cov lus "vuam pas nrig" thiab "electrode" feem ntau siv synonymously. Tus pas electrode siv nyob rau hauv tus txheej txheem no yog ob qho tib si kev ua haujlwm (los tsim cov arc) thiab ib tus neeg siv ua haujlwm (los ua tus weld). Piv txwv li, 6011 thiab 7018 cov hluav taws xob tau sib tham ua ntej tseem hu ua vuam pas nrig hauv smaw, raws li lawv ua tiav ob lub luag haujlwm. Qhov no Overlap yog vim li cas ob nqe lus no nquag tsis meej pem.
Qhov sib txawv: cov qauv thiab muaj nuj nqi
Cov lus tseem ceeb ntawm kev dag nyob hauv lawv qhov kev ua haujlwm thiab thawj qhov haujlwm:
Tau: "electrode" yog ib lo lus dav dav uas suav nrog txhua tus neeg ua ke siv los tsim cov arcs, seb puas muaj kev pab cuam lossis tsis muaj kev siv tes. "Vuam Qws" yog lub ntsiab lus nqaim, hais txog cov lus qhia tshwj xeeb rau cov neeg siv cov hlau, uas tej zaum yuav yog lossis tsis ua raws li cov electrodes.
Muaj nuj nqi: kev ua haujlwm electrode yog los ua hluav taws xob thiab tsim kho ib lub arc. Vuam Rod txoj haujlwm tseem ceeb yog muab cov hlau muab rau cov hlau. Thaum qee qhov vuam pas nrig (zoo li Smaw Lo Tshuaj
Piv txwv li, hauv Tig vuam, Tungsten Electrode kev coj hluav taws xob los tsim lub arc, tab sis nws tsis yog vuam pas nrig. Tus pas nrig cais tau siv los ntxiv cov hlau ntxiv rau lub pas dej Weld yog qhov vuam qws tab sis tsis yog electrode. Hauv qhov no, ob qho tib si yog qhov sib txawv.
Xaus: Hais txog tab sis tsis zoo tib yam
Vuam pas nrig thiab hluav taws xob muaj feem xyuam tab sis tsis muaj cov ntsiab lus sib pauv tau. Txhua qhov vuam pas uas ua raws li cov lus qhia, arc -}}}}, tungsten) tsis yog vuam pas nrig. Ib yam li ntawd, tsis yog tag nrho cov kab txiav vuam yog cov electrodes {{} pooj cov txheej txheem hauv arc vuam (piv txwv li, tig) tsis elecondodes.
Hauv ntej, lawv txoj kev sib raug yog nyob ntawm txoj kev vuam: lawv yuav sib tshooj hauv qee cov txheej txheem tab sis nyob twj ywm hauv lwm tus. Hais meej qhov no pab kom cov kev sib txuas lus zoo rau hauv kev ua haujlwm vuam ua haujlwm, cov khoom xaiv cov khoom siv, thiab kev sib tham thiab kev sib tham.
