Enqubweni yokukhiqiza ye-welding yensimbi, kuzoba khona ukuvela kweziphambeko zensimbi uma indlela yokushisela ingalungile.Ukukhubazeka okuvame kakhulu ukuqhekeka okushisayo, ukuqhekeka okubandayo, ukuklebhuka kwe-lamellar, ukuntuleka kokuhlanganiswa nokungena okungaphelele, i-stomata ne-slag.

Ukuqhekeka okushisayo.

Ikhiqizwa ngesikhathi sokupholisa kwe-weld.Isizathu esikhulu yi-sulphur ne-phosphorus ensimbi kanye ne-welding yakha ezinye izingxube ze-eutectic, izingxube ziqinile kakhulu futhi ziqinile.Ngesikhathi sokupholisa kwe-weld, izingxube ze-eutectic zizoba sesimweni sokushuba ukuze ziqhekeke kalula.

Ukuqhekeka okubandayo.

Yaziwa nangokuthi ukuqhekeka okubambezelekile, ikhiqizwa isukela ku-200℃ekamelweni lokushisa.Izoqhekeka ngemva kwemizuzu embalwa ngisho nezinsuku ezimbalwa.Isizathu sihlobene eduze nomklamo wesakhiwo, izinto zokushisela, ukugcinwa, ukufaka isicelo kanye nezinqubo zokushisela.

Lamellar Ukudabula.

Lapho izinga lokushisa lokushisela selehlile lafinyelela kuma-degree angu-400, okunye ukujiya kwepuleti likhulu futhi kuphakeme kakhulu kunokungcola, ikakhulukazi okuqukethwe kwesibabule, futhi kunokufana okuqinile nokuqondisa okugoqayo eduze kweshidi lamandla aphezulu okuhlukaniswa kwensimbi ye-alloy ephansi uma kunjalo. ngaphansi kwamandla perpendicular kuya ukujiya isiqondiso inqubo yokushisela, izokhipha isiqondiso rolling wanyathela imifantu.

Ukungabi ne-Fusion kanye Nokungena Okungaphelele.

Kokubili imbangela iyafana, ukungafaneleki kwepharamitha yezobuchwepheshe, izilinganiso kanye nobukhulu begroove, ukuhlanzeka okwanele kwe-groove ne-weld surface noma ubuchwepheshe bokushisela obumpofu.

Stomata.

Isizathu esiyinhloko sokukhiqiza i-porosity ku-weld sinokuxhunyaniswa nokukhethiwe, okugciniwe nokusetshenziswa kwezinto zokushisela, ukukhethwa kwemingcele yenqubo yokushisela, ukuhlanzeka kwe-groove kanye nezinga lokuvikela le-weld pool.

I-Slag.

Uhlobo, ukuma nokusatshalaliswa kwe-non-metallic inclusions kuxhunywe ezindleleni zokushisela kanye nokwakheka kwamakhemikhali we-welding, Flux kanye nensimbi ye-weld.
