Inqubo yokukhiqiza ipayipi lensimbi eshiselwe iyishidi lensimbi, i-strip, nezinye izindlela zokubumba ezahlukahlukene zisebenzisa i-strand press roll noma i-helical direction curling ibe yisimo esifiselekayo se-cross-sectional, bese ngokushisa, ingcindezi, izindlela ezihlukene zokushisela ndawonye ukuze thola insimbi. Ngakho-ke, amaphutha epayipi lensimbi elihlanganisiwe lihlukaniswe izingxenye ezimbili: ukukhubazeka kwesisekelo sensimbi kanye nokukhubazeka kwe-weld.

1. Isici se-steel base material
Impahla yeshidi iba namaphutha ngemva kokugingqika nezinye izinqubo, eziningi zepulani, ezihambisana nongaphezulu; ubuthakathaka babo obuyinhloko delamination, inclusions, imifantu, ukugoqa, njll, okuyinto ezivame kakhulu layered amaphutha angaphakathi. I-Stratification izokhiqiza imifantu ehlukahlukene lapho ukucindezeleka kwe-tensile perpendicular ebusweni beshidi nge-hierarchical kuzothinta kakhulu amandla wepayipi lensimbi, akuvunyelwe amaphutha.

2. Amaphutha okushisela
Ukukhubazeka kwe-Weld kubhekisela kusici ngesikhathi sokushisela noma ngemva kokushisela okuholela ekutheni i-weld ihlukaniswe ibe yimifantu, ama-pores, i-slag, ukungena okungaphelele, ukuhlanganisa okungaphelele, ukukhubazeka kwe-weld undercut. I-weld porosity ejulile, i-slag, njll. amaphutha aminyene angama-dimensional amathathu, ukuqhekeka, ukuntuleka kokuhlanganisa kanye nezinye iziphambeko esimweni sefulethi, umonakalo omkhulu. I-strip slag, ukungena okungaphelele kanye nokunye ukukhubazeka esimweni sokuhlubuka, ukulimala okukhulu. Ama-pores, ama-slag nezinye izici ezincane ezifana nephuzu kuleli cala. Ukulimala kwe-Weld okungenzeka kakhulu kubangele amandla ensimbi, ipulasitiki nezinye izinkinga, okuthinta kakhulu ikhwalithi yensimbi, ikhwalithi yepayipi lensimbi eshiselwe kuthinta ngokuqondile ukusebenza okuphephile nempilo yesevisi yamapayipi kawoyela negesi, futhi ngaleyo ndlela nokuhlolwa kwe-weld ikakhulukazi imifantu yokushisela, izimbotshana, i-slag, ukungena okungaphelele, ukuhlangana okungaphelele nokunye ukutholwa kwamaphutha okuyingozi kokukhubazeka.
