(LSAW - Longitudinal Submerged Arc Welding), yayifana ne-welding manual (LSAW - Longitudinal Submerged Arc welding), eyayifana ne-welding manual ye-LSAW-Longitudinal Submerged Arc welding. Indawo kukuba kunye nentsalela yokubumba, kodwa i-slag ayikho i-electrode edibeneyo. Ikhethekileyo kwi-melting flux. Le nkqubo yokugquma iqulathe ifunnel edityaniswe ngombhobho ukuya ngaphambili kwi-flux.

I-five-wire submerged arc welding wire diameter kufuneka ikhethwe ngokungqinelana ne-welding yangoku, xa iingcingo ezi-5 zangoku kwi-diameter yocingo efanayo ukuziqhelanisa noluhlu lwangoku, ungasebenzisa i-wire diameter indibaniselwano efanayo. Iingcingo ezintlanu ezintywiliselwe i-arc welding yangoku kunye ne-arc voltage useto, ungacinezela i-silk ephezulu yangoku, i-voltage ngokuthe ngcembe itshintshela kwi-five wire encinci yangoku kunye ne-voltage. Ukwehla ngokubanzi kwangoku kwe-10% ukuya kwi-30% yomgca kuncitshiswe ngokuthe ngcembe, i-arc kwi-1 ~ 3 V yokuzuza kwamandla ombane yanda ngokuthe ngcembe.
