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.
