Ipayipi lensimbi elifakwe ngaphansi kwe-arc elihlanganisiwe ngezinye izikhathi lihlangabezana nezimo ezithile enqubweni yokukhiqiza, njengezimbobo zomoya.Uma kunezimbobo zomoya kumthungo wokushisela, kuzothinta ikhwalithi yepayipi, lenze ipayipi livuze futhi libangele ukulahlekelwa okukhulu.Lapho ipayipi yensimbi isetshenziswa, izophinde ibangele ukugqwala ngenxa yokuba khona kwemigodi yomoya futhi inciphise isikhathi sesevisi yepayipi.Isizathu esivame kakhulu sezimbobo zomoya ku-spiral steel pipe welding seam wukuba khona kokugeleza kwamanzi noma ukungcola okuthile enqubweni yokushisela, okuzodala izimbobo zomoya.Ukuze uvimbele lokhu, udinga ukukhetha ukwakheka okulinganayo kwe-flux ukuze kungabikho ama-pores ngesikhathi sokushisela.
Lapho ushisela, ubukhulu bokuqoqwa kwe-solder buzoba phakathi kuka-25 no-45. Ukuze uvimbele izimbobo zomoya ebusweni bepayipi lensimbi elivunguzayo, ingaphezulu lepuleti lensimbi kufanele liphathwe.Ngesikhathi sokushisela, konke ukungcola kwe-steel plate kufanele kuhlanzwe kuqala ukuvimbela ezinye izinto ukuthi zingangeni emthungo wokushisela futhi zikhiqize izimbobo zomoya ngesikhathi sokushisela.
