Koj tuaj yeem tiv tauj peb yog tias koj xav tau avuam tshuab

(1) Vuam cov ntaub ntawv rau phau ntawv arc welding 1. Qhov muaj pes tsawg leeg ntawm vuam pas nrig Lub vuam pas nrig yog lub melting electrode siv nyob rau hauv hluav taws xob arc vuam nrog txheej.Nws yog tsim los ntawm ob ntu: txheej txheej thiab vuam core.

(L) Vuam core.Cov tub ntxhais hlau npog los ntawm txheej txheej hauv vuam pas nrig yog hu ua vuam core.Cov tub ntxhais vuam feem ntau yog cov hlau hlau uas muaj qhov ntev thiab txoj kab uas hla.Thaum lub sij hawm vuam, cov tub ntxhais vuam muaj ob txoj haujlwm: ib qho yog ua cov vuam tam sim no thiab tsim ib qho arc los hloov hluav taws xob rau hauv tshav kub;Lwm qhov yog kom yaj lub vuam core nws tus kheej rau hauv cov hlau muab tub lim thiab fused nrog lub hauv paus hlau los ua ib qho kev sib txuas.

Cov hlau tshwj xeeb uas siv rau vuam tuaj yeem muab faib ua peb hom: carbon structural steel hlau, alloy structural steel hlau thiab stainless hlau hlau.

(2) Tshuaj tawv nqaij.Cov txheej uas nias rau ntawm qhov chaw ntawm lub hauv paus yog hu ua txheej.Txheej txheej txheej uas muaj ntau yam minerals nyob rau sab nraud ntawm lub vuam pas nrig tuaj yeem ua kom ruaj khov ntawm arc
