Pambuyo otentha adagulung'undisa machubu zitsulo, kuyenga zitsulo zitsulo, ndi ingot kuwononga dongosolo kuponya, kuchotsa zilema ndi microstructure wa chifukwa wandiweyani PIPE, bwino makina katundu. Mpweya thovu pamaso zitsulo chitoliro, ming'alu ndi lotayirira, pambuyo otentha anagubuduza pa kutentha ndi kuthamanga adzakhala welded pamodzi.

Ngakhale pali ubwino ambiri otentha adagulung'undisa zitsulo chitoliro, koma zofooka zake ziyenera kukhala zomveka, pambuyo zitsulo otentha-anagulung'undisa, sanali zitsulo inclusions mu zitsulo mkati mbamuikha mu magawo woonda, stratification. Zosanjikiza mu makulidwe a chitsulo pakugwira ntchito kwamphamvu kunawonongeka kwambiri, pali interlayer misozi weld shrinkage.

Akhala zitsulo otentha adagulung'undisa, ayenera kukhala patsogolo luso, ngati luso sadutsa, zitsulo m'goli yotsalira nkhawa chifukwa kuzirala pa otentha anagubuduza. Kupsinjika kotsalira pakalibe mphamvu zakunja kumakhala koyenera mkati, koma ngati zitsulo zakunja zakunja zimakhudzidwa kumlingo wina, mwachitsanzo, zidzakhala ndi zotsatirapo za mapindikidwe, kukhazikika, kudana ndi kutopa.

Pamene chitsulo pambuyo otentha anagubuduza, m'mphepete m'lifupi ndi kulamulira makulidwe si zabwino pankhaniyi chifukwa matenthedwe kukula ndi chidule mfundo, chiyambi cha otentha adagulung'undisa zitsulo, kutalika, makulidwe ndi muyezo, koma pamapeto padzakhala zolakwa zina pa nthawi ya kuzirala, kwa m'mphepete m'lifupi mulifupi zitsulo makulidwe thicker ndiye kusiyana zoipa adzakhala zoonekeratu.
