Emkhakheni wokukhiqiza izimboni zesimanje, i-laser welding, njengobuchwepheshe bokushisela obunembayo kanye nokusebenza kahle kakhulu, ithola ukunakwa okukhulayo. Kumakhasimende angaba khona ama-laser welding aphathwayo, ukuqonda umehluko we-laser welding yezinto zensimbi ezihlukene kubalulekile ukuze kuzuzwe umphumela omuhle wokushisela nokuqinisekisa ikhwalithi yokushisela.
Okokuqala, ake sazi izinto ezivamile zensimbi, njenge-carbon steel, insimbi engagqwali ne-alloy steel.
I-Carbon steel ingenye yezinto ezivame kakhulu zensimbi, futhi okuqukethwe kwayo kwekhabhoni okuhlukile kuzothinta ukusebenza kwayo. Insimbi enekhabhoni ephansi inokushisela okuhle. Insimbi enekhabhoni emaphakathi idinga ukuphathwa ngokucophelela ngesikhathi sokushisela, kuyilapho insimbi enekhabhoni ephezulu kunzima ukuyishisela.
Insimbi engagqwali inokumelana nokugqwala okuhle kanye nokumelana ne-oxidation. Izinhlobo ezijwayelekile zifaka i-austenitic stainless steel, i-ferritic stainless steel ne-martensitic stainless steel. Ukwakheka kwabo kanye ne-microstructure kunquma izici zabo zokushisela.
Insimbi ye-alloy wuhlobo lwensimbi oluthola izakhiwo ezithile ngokungeza izakhi ze-alloying, njengamandla, ukuqina nokumelana nokugqoka.
I-laser welding inezinhlelo zokusebenza eziningi kanye nezinzuzo ezibalulekile kulezi zinsiza zensimbi ezahlukene. Ukunemba kwayo okuphezulu kungafinyelela ububanzi obuncane be-weld nokujula, ngaleyo ndlela kunciphise indawo ethinteke ukushisa futhi kuthuthukiswe ikhwalithi yokushisela. Ukuminyana kwamandla aphezulu kwenza ijubane lokushisela ngokushesha futhi lithuthukise kakhulu ukusebenza kahle. Ngaphezu kwalokho, umthungo wokushisela we-laser welding muhle futhi unamandla aphezulu, ongahlangabezana nezidingo ezahlukahlukene eziqinile zezimboni.
Okulandelayo, gxila ekuqhathaniseni nasekuhlaziyeni umehluko obalulekile wezinto ezahlukene zensimbi ngesikhathi senqubo yokushisela i-laser.
Ngokuphathelene nokusatshalaliswa kwezinga lokushisa, i-carbon steel ine-conductivity ephezulu yokushisa, ngakho ukushisa kudluliselwa ngokushesha futhi ukusatshalaliswa kwezinga lokushisa kuyafana. Kodwa-ke, insimbi engagqwali ine-conductivity ephansi yokushisa futhi ijwayele ukukhiqiza izinga lokushisa eliphezulu lendawo ngesikhathi sokushisela, okudinga ukulawula okunembe kakhudlwana.
Izimo ze-deformation nazo ziyahlukahluka. Ngokuvamile, ukuguqulwa kwe-carbon steel kuncane, kuyilapho insimbi engagqwali, ngenxa ye-coefficient yayo enkulu yokwandisa okushisayo, ijwayele ukuguga okukhulu ngesikhathi senqubo yokushisela.
Ngokuphathelene nezinguquko zokubunjwa, ngesikhathi senqubo ye-welding yensimbi ye-alloy, ukusatshalaliswa nokulahlekelwa okuvuthayo kwezakhi ze-alloying kuzoba nomthelela obalulekile kwikhwalithi ye-welding.
Ezinsimbi ezihlukene, nansi imingcele yokushisela nge-laser neziphakamiso zobuchwepheshe.
Nge-carbon steel, isivinini esiphezulu sokushisela namandla e-laser amaphakathi angamukelwa ukuze kuncishiswe okokufaka ukushisa futhi kugwenywe ukushisela ngokweqile.
Insimbi engagqwali idinga isivinini esiphansi sokushisela namandla aphezulu. Ngesikhathi esifanayo, qaphela ukusetshenziswa kwegesi yokuvikela ukuvimbela i-oxidation.
Imingcele yokushisela yensimbi ye-alloy idinga ukulungiswa ngokuvumelana nokwakheka kwe-alloy ethize ukuze kuqinisekiswe ukusatshalaliswa okufanayo kwezakhi ze-alloying.
Sengiphetha, i-laser welding inamathemba abanzi ekucutshungulweni kwensimbi. Ukuba khona kwe-laser welding kungabonakala emikhakheni efana nokukhiqiza izimoto, i-aerospace, imishini kagesi, kanye nemishini yezokwelapha.
Isibonelo, ekukhiqizeni izimoto, i-laser welding isetshenziswa kabanzi ekuxhumekeni kwezakhiwo zomzimba wemoto, ukuthuthukisa amandla nokuphepha komzimba wemoto. Emkhakheni we-aerospace, ekushiseni kwezingxenye zensimbi ye-alloy high-strength, i-laser welding ingaqinisekisa ukunemba okuphezulu kanye nekhwalithi.
Ukuze ukwazi ukuthola imiphumela engcono yokushisela ekusebenzeni kwangempela, sincoma ukuthi usebenzise [igama lomkhiqizo] wethu ophathwa ngesandla we-laser welder. Ifaka ubuchwepheshe be-laser obuthuthukisiwe, ukusebenza okuzinzile, nokusebenza okulula, futhi ingahlangabezana nezidingo zakho zokushisela zezinto ezihlukile zensimbi. Kungakhathaliseki ukuthi uyimboni encane yokucubungula noma ibhizinisi elikhulu lokukhiqiza, umkhiqizo wethu uzoba umsizi onamandla kuwe wokuthuthukisa ikhwalithi yokushisela nokusebenza kahle.
