Ajija welded paipugbóògì nlo gbona yiyi okun.Akoonu alloy ti okun nigbagbogbo kere ju awọn onipò ti o jọra ti awo irin, imudara weldability ti paipu welded ajija.Nitori awọn sẹsẹ itọsọna ti ajija welded paipu okun ni ko papẹndikula si paipu aksi itọsọna, awọn kiraki resistance ti ajija welded paipu ohun elo.

Nitori ti awọn oto išẹ ti ajija pipe, nigbati ajija welded pipe iredanu paipu lodo, awọn weld jiya wahala ati àjọ-wahala jẹ jo kekere, fifún ẹnu ni gbogbo ko ni Oti ti ajija weld, ki awọn ti o ga aabo.Ajija weld ti o wa nitosi abawọn pẹlu agbara ajija ti o jọra jẹ kere, nitorinaa eewu imugboroja kii ṣe.

Paipu irin ti a tẹriba si titẹ inu, nigbagbogbo ninu ogiri lori ohun elo akọkọ meji ti agbara, aapọn radial δY ati axial stress δX.Wahala abajade weld δ = δY (l/4sin2α + cos2α) 1/2, eyiti, α jẹ igun helix ti paipu weld ajija.Igun hẹlikisi ti paipu weld ajija ni gbogbogbo awọn iwọn 50-75, nitorinaa aapọn abajade ti ajija nla.Ni iṣẹ kanna labẹ titẹ ti iwọn ila opin kanna ajija welded paipu ogiri sisanra le dinku pupọ, ọgbin pipe le ṣee ṣe sinu alaja kekere kan.
