(LSAW - Longitudinal Submerged Arc Welding), yakange yakafanana neyemanyoro welding (LSAW - Longitudinal Submerged Arc welding), iyo yaive yakafanana neiyo manual welding yeLSAW-Longitudinal Submerged Arc welding. Nzvimbo yacho ndeyokuti iine mold yakasara, asi slag haisi iyo yakavharwa electrode. Iyo inonyanya kunyunguduka flux. Iyi yekupfekedza sisitimu ine funnel yakasungwa nepombi kuenda kumberi kwekuyerera.

Mashanu-waya akanyudzwa arc welding waya dhayamita inofanirwa kusarudzwa zvinoenderana neyakakwenenzverwa ikozvino, apo mawaya mashanu ari mudhayamita imwechete yewaya kuti aenderane neazvino renji, unogona kushandisa imwechete waya dhayamita musanganiswa. Waya shanu dzakanyura arc welding ikozvino uye arc voltage marongero, unogona kudzvanya 1 sirika yakakwira ikozvino, iyo voltage zvishoma nezvishoma ichichinja kune mashanu waya diki ikozvino uye voltage. Pazvino kuderera kwe10% kusvika ku30% yemutsara zvishoma nezvishoma, iyo arc mu1 ~ 3 V voltage kuwedzera zvishoma nezvishoma.
