(I-LSAW - I-Longitudinal Submerged Arc Welding), yayifana ne-welding manual (LSAW - Longitudinal Submerged Arc welding), eyayifana nokushisela i-LSAW-Longitudinal Submerged Arc welding. Indawo ukuthi inezinsalela zesikhunta, kodwa i-slag ayiyona i-electrode eboshwe. Ikhethekile ekuncibilikeni kwe-melting. Lolu hlelo lokumboza luqukethe ifaneli eshiselwe ngepayipi ukuya ngaphambili kwe-flux.

I-five-wire submerged arc welding wire diameter kufanele ikhethwe ngokuya nge-welding current, lapho izintambo ezi-5 zamanje ezinobubanzi obufanayo bocingo ukuze zivumelane nobubanzi bamanje, ungasebenzisa inhlanganisela yocingo lobubanzi obufanayo. Izintambo ezinhlanu ezicwilisiwe ze-arc welding zamanje kanye nezilungiselelo ze-arc voltage, ungacindezela u-1 usilika ophezulu wamanje, i-voltage ishintsha kancane kancane ibe yizintambo ezinhlanu zamanje ezincane kanye ne-voltage. Ekwehleni okujwayelekile kwamanje ngo-10% kuya ku-30% womugqa wehla kancane kancane, i-arc ku-voltage engu-1 ~ 3 V yanda kancane kancane.
