Mtengo wa LSAWamatengera ukadaulo wowotcherera wa arc, pogwiritsa ntchito kuwotcherera kwa filler, chitetezo cha tinthu chokwiriridwa arc.

LSAW ndiye chidule cha Chingerezi cha chitoliro chachitsulo chomizidwa pansi pamadzi.Kapangidwe ka mipiringidzo yazitsulo yomizidwa ndi arc yowotcherera yowongoka yachitsulo imaphatikizapo ukadaulo wopanga JCOE, ukadaulo wopangira ma arc wothira pansi ndi ukadaulo wopanga UOE.

Njira yopangira Pipe ya Longitudinal Submerged-arc Welded(LSAW) ili motere:

Akupanga mbale kufufuza → m'mphepete mphero → chisanadze kupinda → kupanga → Pre-kuwotcherera → kuwotcherera mkati → kuwotcherera kunja → Akupanga kuyendera → X-ray anayendera → Kukulitsa → hydraulic mayeso →l.Chamfering → Akupanga kuyendera → X-ray anayendera → maginito tinthu anayendera pa chubu mapeto
