Uburyo bwo gukora bwa Longitudinal Submerged-arc Umuyoboro Weld:

Longitudinal Submerged-arc Welded.

LSAW ni impfunyapfunyo y'Icyongereza ya arc yarengewe na welded igororotse icyuma.Igikorwa cyo kubyaza umusaruro arc yacometse arc umuyoboro wicyuma ugizwe nicyuma gikora tekinoroji ya JCOE, coil ikora tekinoroji yo gusudira arc hamwe na tekinoroji ya UOE.

Inzira yo gukora Longitudinal Submerged-arc Umuyoboro (LSAW) Umuyoboro niyi ikurikira:

Isahani ya Ultrasonic → gusya inkombe → mbere yo kunama → gukora → Mbere yo gusudira eld gusudira imbere → Gusudira hanze → Kugenzura Ultrasonic inspection Kugenzura X-ray → Kwagura test ikizamini cya hydraulic → l.Chamfering inspection Kugenzura Ultrasonic inspection Kugenzura X-ray inspection kugenzura ibice bya magnetiki kugenzura impera

Ubushinwa lsaw yasudiye uruganda rukora imiyoboro

Ubworoherane bwa diameter yo hanze, uburebure bwurukuta, uburebure n'uburemere:

Hanze ya Diameter	Diameter yo hanze yibirundo by'imiyoboro ntishobora gutandukana kurenza ± 1% uhereye kumurambararo wagaragaye.
Ubunini bw'urukuta	Umubyimba wurukuta umwanya uwariwo wose ntushobora kurenza 12.5% munsi yubugari bwurukuta.
Uburebure	Ibirundo by'imiyoboro bigomba gutangwa muburebure bumwe, uburebure bubiri, cyangwa muburebure bumwe nkuko bigaragara muburyo bwo kugura, ukurikije imipaka ikurikira:	Uburebure bumwe	16 kugeza 25ft (4.88 kugeza 7,62mm), santimetero
		Uburebure bubiri	Kurenga 25ft (7.62m) hamwe byibuze byibuze 35ft (10.67m)
		Uburebure bumwe	uburebure nkuko byasobanuwe hamwe no gutandukana byemewe ± 1 muri.
Ibiro	Buri burebure bw'ikirundo cy'ipine bugomba gupimwa ukwe kandi uburemere bwacyo ntibushobora gutandukana hejuru ya 15% hejuru ya 5% cyangwa munsi ya 5% munsi yuburemere bwacyo, ubaze ukoresheje uburebure bwacyo nuburemere bwacyo muburebure.
