Ko te tukanga hanga i te paipa LSAW (Rongonui Ruku-ā-Arc Welded Paipa) e whai ake nei:
Te whakamātautau pereti ultrasonic → te mira taha → te piko-mua → te hanga → Te whakarewa-mua → Te whakarewa ā-roto → Te whakarewa ā-waho → Te tirotiro ultrasonic → Te tirotiro hihi-X → Te whakawhanui → te whakamātautau waipēhi → te whakakoi l. → Te tirotiro ultrasonic → Te tirotiro hihi-X → te tirotiro matūriki aukume i te pito ngongo
