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 ezahlukene 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 okuqinile kwe-perpendicular ebusweni beshidi nge-hierarchical kuzothinta kakhulu amandla epayipi 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 nezinye iziphambeko 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, kanjalo nokuhlolwa kwe-weld ikakhulukazi imifantu yokushisela, izimbotshana, i-slag, ukungena okungaphelele, ukuhlangana okungaphelele nokunye ukutholwa kwamaphutha okuyingozi kokukhubazeka.
