Tsarin sarrafawa:
● Shirye-shiryen Plate: An zaɓi faranti na ƙarfe masu inganci bisa ƙayyadaddun buƙatu, tabbatar da kayan aikin injiniya da ake buƙata da abun da ke ciki.
● Ƙirƙira: Ana siffanta farantin karfe zuwa bututun silindi ta hanyar matakai kamar lankwasa, mirgina, ko latsawa (JCOE da UOE).An riga an lanƙwasa gefuna don sauƙaƙe walda.
Welding: Ana amfani da walda mai nutsewa (SAW), inda ake kiyaye baka a ƙarƙashin matsi.Wannan yana samar da ingantattun welds tare da ƙarancin lahani da kyakkyawar haɗuwa.
● Binciken Ultrasonic: Bayan waldawa, ana gudanar da gwajin ultrasonic don gano duk wani lahani na ciki ko na waje a cikin yankin weld.
● Fadadawa: Ana iya faɗaɗa bututu don cimma diamita da ake so da kauri na bango, haɓaka daidaiton girman.
● Binciken Ƙarshe: Gwaji mai mahimmanci, ciki har da dubawa na gani, ƙididdigar ƙira, da gwaje-gwajen kayan aikin injiniya, yana tabbatar da ingancin bututu.
Amfani:
● Ƙimar Kuɗi: Bututun LSAW suna ba da mafita mai inganci don manyan bututun diamita da aikace-aikacen tsari saboda ingantaccen tsarin ƙirar su.
● Ƙarfi mai ƙarfi: Hanyar waldawa ta tsaye tana haifar da bututu tare da kaddarorin inji mai ƙarfi da iri ɗaya.
● Daidaiton Girman Girma: Bututun LSAW suna nuna ma'auni daidai, yana sa su dace da aikace-aikace tare da tsananin haƙuri.
● Ingancin Weld: Ƙarƙashin ƙwanƙwasa arc yana samar da ginshiƙai masu kyau tare da kyakkyawar haɗuwa da ƙananan lahani.
