Welded karfe bututu za a iya wajen zuwa kashi uku Categories bisa ga forming tsari:
1. Electric juriya welded karfe bututu
Electric juriya welded karfe bututu, Turanci sunan ERW (Electric juriya welded bututu), weld irin ne madaidaiciya kabu.Weld ɗin juriya yana ɗaukar hanyar waldawar matsa lamba ba tare da ƙarfe mai filler ba.Babu cika wasu abubuwan da aka gyara a cikin kabu na weld.Tasirin fata da tasirin kusancin babban mitar halin yanzu yana sa gefen farantin nan take mai zafi zuwa zafin walda, kuma ana yin ƙirƙira ta hanyar matse abin nadi na extrusion.Welds na nama.
Juriya welded karfe bututu za a iya raba kashi biyu Categories: high mita juriya waldi HFW (High mita welded bututu) da kuma low mita juriya waldi LFW (Low mita waldi).
An fi amfani da bututun ƙarfe na ERW don jigilar tururi da abubuwa masu ruwa kamar mai da iskar gas, kuma suna iya biyan buƙatu daban-daban na babban matsin lamba da ƙarancin ƙarfi.A halin yanzu, sun mamaye matsayi mai mahimmanci a fagen bututun sufuri a duniya.
2. Karfe welded karfe bututu
Karfe welded bututu, Turanci sunan SSAW (Spiral submerged-baka waldi bututu), weld irin ne karkace kabu.Ana amfani da hanyar waldawar baka mai nutsewa, kuma an yi waldi na ciki da na waje.Submerged arc waldi (ciki har da submerged baka surfacing da electroslag surfacing, da dai sauransu) hanya ce mai mahimmanci na walda, wanda ke da fa'idodin ingantaccen walda mai ƙarfi, haɓakar walda mai girma, babu hasken baka da ƙaramin hayaki da ƙura.
Bututun welded na karkace yana da babban diamita, wanda zai iya kaiwa fiye da 3000mm, kuma ya fi dacewa da jigilar bututun mai girman diamita da tsarin gine-gine.
