1. Kuenzanisa kwekugadzira nzira
Nzira yekugadzira yemusono musono pombiiri nyore. Iwo makuru ekugadzira maitiro akakwira-frequency welded yakatwasuka seampombi yesimbiuyepasi pemvura arc welded yakatwasuka musono simbi pombi. Yakatwasuka musono simbi pombi ine yakakwirira kugadzirwa kunyatsoshanda, yakaderera mutengo uye kukurumidza kukura.
Simba respiral simbi pombiinowanzokwirira kupfuura iyo yakatwasuka seam simbi pombi. Iyo huru yekugadzira maitiro ndeye yakadzika arc welding. Spiral simbi machubhu anogona kugadzira welded machubhu ane madhayamita akasiyana emabhiridha ehupamhi hwakafanana, kanawelded tubesnemadhayamita akakura kubva kumabheti akamanikana.
Nekudaro, zvichienzaniswa neakatwasuka seam simbi mapaipi ehurefu hwakafanana, kureba kwewelding kwakawedzera ne30% uye 100% zvichiteerana, uye kukurumidza kwekugadzira kwakaderera. Naizvozvo, hombe dhayamita simbi pombi anonyanya welded ne spiral welding, uye dhayamita dhayamita simbi pombi anonyanya welded nekutwasamuka musono welding.
Pakugadzirahombe-dhayamita yakatwasuka musono pombi dzesimbimuindasitiri, T-shaped welding tekinoroji inoshandiswa, kureva kuti, nhamba diki yemapombi esimbi yakatwasuka akaiswa butt akabatanidzwa uye akabatana kuti asangane nehurefu hunodiwa hwepurojekiti. Kukanganisa kweT-yakaita seam seam simbi pombi ichawedzerwa zvakanyanya, uye welding yakasara yekushushikana kweT-shaped weld yakakura. Iyo weld metal inowanzova pasi pe triaxial stress, iyo inowedzera mukana wekuputika.
Uye zvakare, zvinoenderana nehunyanzvi mirairo yekunyudza arc welding, yega yega weld ichave pasi pearc inorova uye arc yekudzima kurapwa. Nekudaro, imwe neimwe pombi yesimbi haigone kusangana nemamiriro aya panguva yekutenderedza seam welding, saka kwakawanda kukanganisa kwewelding kunogona kuitika panguva yekudzima arc.
2. Kuenzanisa kwemaitiro ekugadzirisa
Kana iyo pombi ichiiswa mukati mekumanikidzwa kwemukati, maviri makuru ekumanikidza anowanzo kugadzirwa pamadziro epombi, kureva radial stress uye axial stress. Kushushikana kwakanyanya paweld, uko α Ndiyo weld spiral angle yespiral simbi pombi.
Kushushikana kwakazara pa spiral weld ndiko kunetseka kukuru kwepombi yesimbi yakatwasuka. Pasi pesimba rimwe chete rekushanda, ukobvu hwemadziro epombi dzesimbi dzakatenderedza dzine dhayamita imwe yepombi idiki pane iyo yepombi dzakatwasuka dzesimbi.
