Hlau kauj phaj: Ua haujlwm raws li cov khoom siv thawj rau muab kauv submerged arc welded kav dej thiab tshuaj ntsuam xyuas nws cov kev sib raug zoo. Ua ntej tsim, tus hlau chev phaj undergoes theem, ntug kev ua kom huv, ua kom huv si, thiab ua ntej cov txheej txheem ua ntej thiab zoo.
Vuam hlau: vuam hlau yog tus hlau xaim siv los sau ntawm Weld sib koom ua ke thaum lub sijhawm vuam. Kev xaiv ntawm vuam hlau yog qhov tseem ceeb rau kev vuam zoo, xav kom muaj zog, thiab lwm yam ntxwv los xyuas kom ruaj khov thiab kev ntseeg tau thaum lub sij hawm vuam.
Flux: Flux ua lub luag haujlwm ntawm kev tiv thaiv weld hlau thiab tshem tawm cov khoom siv impurities tsim thaum lub sij hawm vuam ua tau zoo ntawm weld sib koom tes.
