01 Kuyini i-ijoyinti elihlanganisiwe
Ijoyinti elihlanganisiwe libhekisela ejoyintini lapho izingcezu zomsebenzi ezimbili noma ngaphezulu zixhunywe ngokushisela. Ijoyinti elihlanganisiwe lokushisela okuhlanganisiwe lakhiwa ngokushisa kwendawo okuvela emthonjeni wokushisa okushisa okuphezulu. Ijoyinti elihlanganisiwe lakhiwe indawo yokuhlangana (indawo yokushisela), umugqa wokuhlanganisa, indawo ethintekile ekushiseni, kanye nendawo yensimbi eyisisekelo, njengoba kuboniswe esithombeni.
02 Kuyini i-butt joint
Isakhiwo sokushisela esivame ukusetshenziswa siyinhlanganisela lapho izingxenye ezimbili ezixhumene zishiselwa khona endaweni efanayo noma e-arc phakathi nendawo yenhlanganisela. Isici ukushisa okufanayo, amandla afanayo, kanye nekhwalithi yokushisela elula ukuyiqinisekisa.
03 Kuyini i-umsele wokushisela
Ukuze kuqinisekiswe ukungena kanye nekhwalithi yamajoyinti ahlanganisiwe, futhi kuncishiswe ukuguquguquka kokushisela, amajoyinti ezingxenye ezihlanganisiwe ngokuvamile acutshungulwa kusengaphambili abe yizimo ezahlukahlukene ngaphambi kokushisela. Ama-groove ahlukene okushisela afanelekela izindlela ezahlukene zokushisela kanye nobukhulu bokushisela. Izinhlobo ze-groove ezivamile zifaka: Okufana no-I, okufana no-V, okufana no-U, okufana no-V ohlangothini olulodwa, njll., njengoba kuboniswe esithombeni.
Izinhlobo ezivamile zemifantu yamalunga ezinqe
04 Ithonya Lefomu Lomsele Ohlangene Wezinqe KuUkushisela Okuhlanganisiwe Kwe-Laser Arc
Njengoba ubukhulu bomsebenzi ohlanganisiwe bukhula, ukufeza ukushisela ohlangothini olulodwa kanye nokwakheka kwamapuleti aphakathi namakhulu (amandla e-laser <10 kW) kuvame ukuba yinkimbinkimbi kakhulu. Ngokuvamile, amasu ahlukene okushisela adinga ukuthathwa, njengokuklama amafomu afanele okushisela noma ukugcina izikhala ezithile zokudokha, ukuze kufezwe ukushisela kwamapuleti aphakathi namakhulu. Kodwa-ke, ekushiseleni kokukhiqiza kwangempela, ukugcina izikhala zokudokha kuzokwandisa ubunzima bezinto zokushisela. Ngakho-ke, ukwakheka komsele kuba yinto ebalulekile ngesikhathi senqubo yokushisela. Uma ukwakheka komsele kungenangqondo, ukuzinza nokusebenza kahle kokushisela kuzothinteka kabi, futhi kwandisa nengozi yokukhubazeka kokushisela.
(1) Ifomu lomsele lithinta ngqo ikhwalithi yomsele wokushisela. Umklamo womsele ofanele ungaqinisekisa ukuthi insimbi yocingo lokushisela igcwele ngokugcwele kumsele wokushisela, okunciphisa ukwenzeka kweziphambeko zokushisela.
(2) Ukuma kwejometri yomsele kuthinta indlela ukushisa okudluliselwa ngayo, okungaqondisa kangcono ukushisa, kufeze ukushisa nokupholisa okufanayo, futhi kusize ekugwemeni ukuguquguquka kokushisa kanye nokucindezeleka okusele.
(3) Ifomu lomsele lizothinta ukuma kwesigaba esiphambene somthungo wokushisela, futhi lizoholela ekutheni ukuma kwesigaba esiphambene somthungo wokushisela kuhambisane kakhulu nezidingo ezithile, njengokujula nobubanzi bokungena komthungo.
(4) Ifomu elifanele lomsele lingathuthukisa ukuzinza kokushisela futhi linciphise izimo ezingazinzile ngesikhathi senqubo yokushisela, njengokuchaphaza kanye nokukhubazeka okungaphansi.
Njengoba kuboniswe kuMfanekiso 3, abacwaningi bathole ukuthi ukusebenzisa i-laser arc composite welding (amandla e-laser angu-4kW) kungagcwalisa i-groove ngezendlalelo ezimbili kanye nama-pass amabili, okuthuthukisa ngempumelelo ukusebenza kahle kwe-welding; Ukushintshwa okungenasici kwe-MnDR enobukhulu obungu-20mm kufezwe kusetshenziswa i-laser arc composite welding enezendlalelo ezintathu (amandla e-laser angu-6kW); Ukushintshwa kwe-laser arc composite welding kwasetshenziswa ukushintshwa kwensimbi ephansi yekhabhoni engu-30mm ngobukhulu ezizendlalelo eziningi kanye nama-pass, futhi isimo se-cross-sectional se-welded joint sasizinzile futhi silungile. Ngaphezu kwalokho, abacwaningi bathole ukuthi ububanzi be-rectangular grooves kanye ne-engeli ye-grooves enomumo we-Y kunomthelela omkhulu emphumeleni wokuvinjelwa kwendawo. Lapho ububanzi be-groove enomumo we-rectangular bukhona≤4mm futhi i-engeli yomsele omise okwe-Y iwu-≤60 °, isimo sesigaba esiphambene somthungo wokushisela sibonisa imifantu ephakathi kanye nezimbobo zodonga oluseceleni, njengoba kuboniswe esithombeni.
Umphumela Wefomu Lomsele Emkhakheni Wesiphambano Sesigaba Sokushintshwa Kwezinsimbi
Ithonya Lobubanzi Be-Groove kanye ne-Angle Esigabeni Esiphambene I-Mofology Yama-Welds
Isifinyezo se-05
Ukukhethwa kwefomu le-groove kudinga ukucabangela ngokuphelele izidingo zomsebenzi wokushisela, izici zezinto ezibonakalayo, kanye nezici zenqubo yokushisela ye-laser arc composite. Ukwakheka kwe-groove efanele kungathuthukisa ukusebenza kahle kokushisela futhi kunciphise ingozi yokukhubazeka kokushisela. Ngakho-ke, ukukhethwa kanye nokwakheka kwefomu le-groove kuyisici esibalulekile ngaphambi kokushisela kwe-laser arc composite kwamapuleti aphakathi namakhulu.
