(LSAW - Longitudinal Submerged Arc Welding), ua like ia me ka manuale welding (LSAW - Longitudinal Submerged Arc welding), ua like ia me ka manuale welding o LSAW-Longitudinal Submerged Arc welding. ʻO kahi kahi me ke koena mold, akā ʻo ka slag ʻaʻole ia ka electrode i uhi ʻia. He mea kūikawā i ka hoʻoheheʻe ʻana. Aia kēia ʻōnaehana hoʻouhi me kahi funnel i wili ʻia ma kahi paipu i mua o ka flux.

Elima uea submerged arc kuʻihao uea anawaena pono e koho e like me ka kuʻihao o keia manawa, i ka manawa o keia manawa 5 uea i loko o ka ia uea anawaena e hoʻololi i ka o keia manawa, e hiki ke hoʻohana i ka ia uea anawaena hui. Elima uea submerged arc welding au a me arc voltage hoʻonohonoho, hiki iā ʻoe ke kaomi i ka 1 siliki kiʻekiʻe o kēia manawa, e hoʻololi mālie ka uila i ʻelima uea liʻiliʻi a me ka uila. I ka hoʻohaʻahaʻa maʻamau o kēia manawa o 10% a 30% o ka laina i hoʻohaʻahaʻa ʻia, ua hoʻonui ʻia ke arc i ka loaʻa ʻana o ka volta 1 ~ 3 V.
