Shielded hlau arc vuam ( SMAW ), tseem hu ua phau ntawv hlau arc vuam, yog phau ntawv siv vuam txheej txheem uas siv cov khoom siv tau thiab tiv thaiv hluav taws xob . Raws li cov hluav taws xob melts, npog uas tiv thaiv cov hluav taws xob melts thiab tiv thaiv thaj tsam weld los ntawm oxygen thiab lwm yam atmospheric gases.
Ua kom pom qhov no, qhov ua haujlwm ntawm txheej txheej ntawm SMAW electrode yog dab tsi?
Cov hluav taws xob yog coated nyob rau hauv cov hlau sib xyaw hu ua flux, uas muab cov pa tawm thaum nws decomposes los tiv thaiv kev sib kis, qhia cov deoxidizers kom ntxuav cov weld, ua rau weld tiv thaiv slag rau tsim, txhim kho arc ruaj khov, thiab muab cov ntsiab lus txhim kho txhawm rau txhim kho qhov txuas zoo.
Tsis tas li ntawd, cov txheej txheem ntawm SMAW yog dab tsi? SMAW welding yog a txheej txheem uas siv ib tug consumable electrode uas yog them nrog ib tug flux. Lub tshuab vuam yog txuas mus rau lub zog hluav taws xob, uas tsim los ntawm kev hloov pauv tam sim no (AC) lossis ncaj qha tam sim no (DC) los ua ib qho arc ntawm electrode thiab hlau. Raws li lub pas dej weld txias, nws solidifies tsim ib qho kev sib koom ua ke.
Hauv kev hwm rau qhov no, dab tsi yog qhov ua haujlwm ntawm electrode txheej?
Muaj nuj nqi ntawm Electrode txheej Muab kev tiv thaiv huab cua kom tiv thaiv cov pa oxygen, hydrogen, thiab nitrogen khaws los ntawm cov hlau yaj. Txo qhov sib tov ntawm cov hlau txuas - thaum twg txheej kub hnyiab tawm qeeb dua qhov tseem ceeb. Ua kom qis qis qis ntawm qhov txias ntawm qhov vuam (vim cov txheej txheem tiv thaiv ntawm slag) kom tsis txhob tawv.
Coated electrode vuam yog dab tsi?
Arc vuam nrog a coated electrode yog ib txoj kev uas fusion ntawm hlau yog tsim ua tsaug rau lub tshav kub generated los ntawm ib tug hluav taws xob arc tsim nyob rau hauv lub kawg ntawm ib tug coated electrode thiab lub hauv paus hlau ntawm kev sib koom ua welded . Cov khoom muab tub lim yog tau los ntawm hluav taws xob fusion nyob rau hauv cov duab ntawm me me tee.

Dab tsi yog qhov tseem ceeb thiab qhov hnyav ntawm qhov tsis xws luag?
Qhov hnyav tau txhais raws li qhov uas qhov tsis xws luag tuaj yeem tsim kev cuam tshuam rau software. Qhov hnyav yog qhov ntsuas los qhia txog qhov cuam tshuam thiab cuam tshuam ntawm qhov tsis xws luag ntawm kev ua haujlwm ntawm software. Qhov tseem ceeb: Qhov tseem ceeb yog txhais tau tias yog qhov ntsuas uas txiav txim siab qhov kev txiav txim uas yuav tsum tau kho
Lub luag haujlwm ntawm tus tswv lub tog raj kheej thiab lub tog raj kheej ua haujlwm yog dab tsi?
Thaum koj thawb tus nres pedal, koj yuam kom lub plunger los ntawm tus tswv lub tog raj kheej. Cov kua dej hauv tus tswv lub tog raj kheej raug yuam los ntawm cov kab nres mus rau plaub lub tog raj kheej, ib qho rau txhua lub log. Txhua lub tog raj kheej log zaum nruab nrab ntawm ob lub khau nres thiab muaj lub piston hauv txhua qhov kawg nrog cov roj hmab ntsaws ruaj ruaj kom cov hmoov av tawm
Lub luag haujlwm tseem ceeb ntawm lub zog txuas hluav taws xob yog dab tsi?
Lub luag haujlwm tseem ceeb ntawm lub vuam siv hluav taws xob yog txhawm rau muab lub zog txaus kom yaj sib koom. Txawm li cas los xij nrog MMA lub zog siv hluav taws xob yuav tsum tau muab tam sim no rau yaj qhov kawg ntawm cov hluav taws xob los tsim cov hlau txuas, thiab nws yuav tsum muaj qhov hluav taws xob txaus kom tswj tau lub arc
Dab tsi yog qhov laj thawj thiab nws qhov tseem ceeb hauv qhov xwm txheej tsis saib xyuas yog dab tsi?
Qhov ua rau sib thooj yog kev ua, txawm tias txhob txwm ua lossis tsis saib xyuas, uas tau txiav txim siab ua rau lwm tus puas tsuaj, raug mob, lossis raug kev txom nyem. Nws yog ib qho tseem ceeb uas cov tsev hais plaub tsim kom muaj qhov xwm txheej ntawm tus kheej raug mob vim tsis yog txhua tus thiab txhua yam uas ua rau muaj kev raug mob tuaj yeem raug cai
Dab tsi yog lub luag haujlwm ntawm lub twj tso kua dej ntawm lub tsheb?
Lub hom phiaj ntawm lub tshuab tso dej hauv lub tsheb yog txhawm rau thawb lub tshuab txias los ntawm lub tsheb lub cav thaiv, lub tshuab hluav taws xob thiab lub qhov dej kom tau txais lub cav cua sov kom deb ntawm qhov system. Feem ntau, cov twj tso kua dej tawm ntawm lub crankshaft pulley los yog crankshaft nws tus kheej
