Erw (Kurwanya amashanyarazi Welded) imiyoborobakozwe kuva mumashanyarazi ashyushye bahuza amashanyarazi yombi yimpande zombi. Kurenza inshuro nyinshi zanyuze mumashuri yazungurutse ukoresheje electrode yumuringa.
Gutahura amashanyarazi hagati yabatwara bitera ubushyuhe bukabije bwo kwibanda kumpande, gutera imbere. Iyo ubushyuhe bumwe bumaze kugerwaho, igitutu gikoreshwa, bigatuma habaho inyungu.
Ibiranga imiyoboro ya erw:
Ikirangantego cyarasukuwe.
● Yakozwe no kunyura hejuru-inshuro nyinshi binyuze mumatibahirika no guhuza impera munsi yumuvuduko mwinshi.
● Hanze ya diameter iringaniye kuva ½ kugeza kuri santimetero 24.
● Ubunini bwurukuta buratandukanye kuva 1,65 kugeza 20mm.
Uburebure busanzwe ni 3 m 12, ariko uburebure burebure burahari bisabwe.
● Irashobora kugira ibibaya, imitwe, cyangwa yatinze nkuko byavuzwe numukiriya.
● Imiyoboro ya erw yerekanwe munsi ya ASTM A53 ishimangira imiyoboro myinshi yimiyoboro ikoreshwa mumavuta, gaze, cyangwa imizi yuzuye.
Gukora inzira ya erw imiyoboro:
Steel Coils nibikoresho fatizo byo gukora imiyoboro ya erw.
Imashini yicyuma irasenyuka mubugari nubunini mbere yo kugaburirwa urusyo.
Steel Coils yafunguye ku bwinjiriro bwa rusno ya erw maze arengana urusyo kugirango akore imiyoboro imeze na tube hamwe na gare zimaze igihe kirekire.
Ubuhanga butandukanye nko gusudira, gucana, no kurwanya ibishushanyo bya projection bikoreshwa.
Amashanyarazi ahenze, amashanyarazi-voltage yamashanyarazi yanyuze mu muringa ahinnye kumuyoboro utarandurwa kugirango ushushe impande zifunguye.
Flash Welding ikunze gukoreshwa nkuko bidasaba ibikoresho byo kugurisha.
● arc isohoka muburyo hagati ya EDGES, no ku bijyanye n'ubushyuhe bukwiye, ibyaguzwe hamwe kugirango dusunike ibicuruzwa.
Gutanga amasaro rimwe na rimwe biratunganijwe ukoresheje ibikoresho bya karbide, kandi uturere dusumbiriwe twemerewe gukonja.
● Tubing yakonje irashobora kwinjiza umuzingo kugirango urebe ko diameter yo hanze ituruka kumurongo.
Gusaba imiyoboro ya erw:
Gukoresha imiyoboro isanzwe ya erw ni nkimiyoboro yumurongo wo gutwara amavuta yubugome, gaze kamere, nibindi bikoresho. Bafite impuzandengo yo hejuru kuruta imiyoboro idafite uburwayi kandi irashobora guhura nibisabwa hejuru kandi yo hasi-yo hasi, bikaba bituma bibatabara nkumuyoboro wo gutwara abantu.
● Imiyoboro ya erw, cyane cyane isobanura API 5CT, ikoreshwa muri casing na tubing
● Imiyoboro ya HERES irashobora gukoreshwa nkimiterere yimiterere kubihingwa byamashanyarazi
● Imiyoboro ya erw ikoreshwa munganda zibyara umusaruro nko kubyara ibitotsi, gutunganya imashini, imashini zitunganya, nibindi byinshi
● Erw umuyoboro ukoresha harimo gutanga gaze, amashanyarazi yamashanyarazi, nibindi byinshi.
● Bafite kandi ikoresha mu kubaka, imiyoboro yo munsi y'ubutaka, gutwara amazi yo mu mazi y'ubutaka, n'amazi ashyushye.
