(LSAW - Longitudinal Submerged Arc Vuam), nws yog tib yam li phau ntawv vuam (LSAW - Longitudinal Submerged Arc vuam), uas yog tib yam li phau ntawv vuam ntawm LSAW-Longitudinal Submerged Arc vuam.Qhov chaw yog tias nws yog nrog cov pwm residue, tab sis cov slag tsis yog coated electrode.Nws yog tshwj xeeb hauv melting flux.Qhov txheej txheem txheej txheej no muaj lub funnel welded los ntawm cov yeeb nkab mus rau pem hauv ntej ntawm cov flux.

Tsib-xaim submerged arc vuam hlau txoj kab uas hla yuav tsum tau xaiv raws li cov vuam tam sim no, thaum tam sim no 5 xov hlau nyob rau hauv tib lub xaim txoj kab uas hla kom hloov mus rau qhov tam sim no ntau yam, koj tuaj yeem siv tib txoj kab uas hla.Tsib xaim submerged arc vuam tam sim no thiab arc voltage nqis, koj tuaj yeem nias 1 txhob lo lo ntxhuav siab tam sim no, qhov voltage maj mam hloov mus rau tsib hlau me me tam sim no thiab voltage.Hauv qhov tam sim no kev poob qis ntawm 10% mus rau 30% ntawm txoj kab maj mam txo qis, qhov arc hauv 1 ~ 3 V voltage nce maj mam nce.
