Amalunga amapayipi abophayo, lapho izingxenye ezimbili noma ngaphezulu zisebenzisa inhlanganisela yamalunga ashiselwe, noma ibhekisela ezingxenyeni ezimbili noma ngaphezulu ezixhunywe ngamajoyinti okushisela, okuhlanganisa okushisela, indawo yokuhlanganisa kanye nendawo ethintekile ekushiseni.

Indawo yokuhlanganisa ashiselwe

Ngemva kokufaka insimbi ne-filler metal incibilika isivinini esisheshayo i-Youyi eyakhiwe ngemva kokupholisa nokuqiniswa.Weld kusukela isakhiwo cast of the liquid metal amakristalu, okusanhlamvu amaqhafuqhafu, ukuhlukaniswa, inhlangano akuyona aminyene.Kodwa-ke, ngenxa yechibi elincane le-weld, ukupholisa okusheshayo, ukulawula okuqinile kokwakheka kwamakhemikhali, i-carbon, isulfure, i-phosphorus kuphansi, kodwa futhi ngokulungisa ukwakheka kwamakhemikhali we-alloying weld, iqukethe inani elithile lezinto ezixubile, ngakho-ke ukusebenza kwensimbi yokushisela akuyona inkinga enkulu, ukuhlangabezana nezidingo zokusebenza, ikakhulukazi amandla ukufinyelela kalula.

Indawo ye-Fusion

Indawo encibilikayo kanye nengxenye yoshintsho phakathi kwendawo engancibiliki.Ukwakheka kwamakhemikhali e-fusion zone isicubu esiwugqinsi esingalingani ngokuvamile kuba izicubu eziqinile eziqinile noma izicubu ezishisa ngokweqile.Ukusebenza kwamajoyinti ashiselwe kuvame ukuba kubi kakhulu.Indawo ye-Fusion kanye nendawo ethintekile ekushiseni yendawo eshisiwe ngokweqile (noma indawo yokucisha) iyindawo embi kakhulu yemishini yamajoyinti ashiselwe ezingxenyeni ezibuthakathaka, izothinta kakhulu ikhwalithi yamalunga ashiselwe.

Indawo ethintekile ukushisa

Isakhiwo esincane sezoni ye-weld eshisiwe kanye nezakhiwo ezibangelwa izinguquko esifundeni.Indawo yensimbi enekhabhoni ephansi ethinteke ukushisa ingahlukaniswa ngezindawo ezishiselwe ngokweqile, futhi ingxenye yesifunda soguquko lwesigaba sijwayelekile.

(1) indawo yokushisa ephezulu yokushisa ephezulu ngaphezu kuka-1100℃, okusanhlamvu okumahhadla, ngisho nezicubu ezishisa ngokweqile, ezibizwa ngokuthi isifunda esishisa kakhulu.I-Ductility kanye nokuqina kwehle kakhulu indawo eshiselwe ngokweqile, indawo ethintekile ukushisa iyingxenye embi kakhulu yezakhiwo zemishini.

(2) Izinga lokushisa eliphezulu lokushisisa ukusuka ku-normalization zone endaweni Ac3 kuya ku-1100℃, izinhlamvu zokushisela ezipholile emoyeni ziba zincane ngemva kwenhlangano evamile ebizwa ngokuthi indawo evamile.Izakhiwo ezingcono zemishini yendawo evamile.

(3) ingxenye yesigaba sokushintsha kwezinga lokushisa esiphezulu kuya esifundeni sisuka ku-Ac1 Ac3, ingxenye kuphela yoshintsho lwesigaba senhlangano, esibizwa ngokuthi indawo yenguquko yesigaba esinqunyiwe.Le ndawo okusanhlamvu ukusebenza ngokungalingani nakho kubi.Ngesikhathi ukufakwa Welding, Welding indlela Welding kaningi.Ijoyinti elishiselwe ukushisa okushisa okuphezulu liyinsimbi ye-matrix eshiselwe endaweni kanye nomzimba wokugcwalisa umfaniswano wensimbi encibilikisiwe ngenkathi iqinisa ifomu elincibilikisiwe.Kuye nge-microstructure kanye nezakhiwo zezingxenye ezihlukahlukene zamajoyini ahlanganisiwe zingahlukaniswa zibe izingxenye ezintathu.
