01 Yini ainhlanganisela eshiselwe
Ijoyinti elishiselwe lisho ilunga lapho izinto zokusebenza ezimbili noma ngaphezulu zixhunywe ngokushisela. Ijoyinti elishiselwe le-fusion welding lakhiwa ukushisisa kwendawo okuvela emthonjeni wokushisa onezinga lokushisa eliphezulu. Ijoyinti elishiselwe liqukethe indawo yokuhlanganisa (indawo yokushisela), umugqa wokuhlanganisa, indawo ethinteke ukushisa, nendawo yensimbi eyisisekelo, njengoba kukhonjisiwe esithombeni.
02 Liyini ilunga lezinqe
Isakhiwo sokushisela esivame ukusetshenziswa siyijoyinti lapho izingxenye ezimbili ezixhumene zishiselwa endizeni eyodwa noma i-arc endaweni ephakathi nendawo yejoyinti. Isici ukufudumeza okufanayo, amandla afanayo, futhi kulula ukuqinisekisa ikhwalithi yokushisela.
03 Yini ai-welding groove
Ukuze kuqinisekiswe ukungena kanye nekhwalithi yamalunga ashiselwe, futhi kuncishiswe i-welding deformation, amalunga ezingxenye ezishiselwe ngokuvamile acutshungulwa ngaphambili abe yizimo ezihlukahlukene ngaphambi kokushisela. Ama-welding grooves ahlukene afanele izindlela ezahlukene zokushisela kanye nokuqina kwe-weldment. Amafomu e-groove avamile ahlanganisa: I-i-shaped, i-V-shaped, i-U-shaped, i-unilateral V-shaped, njll, njengoba kuboniswe emfanekisweni.
Izinhlobo ze-groove ezijwayelekile zamalunga ezinqe
04 Umthelela Wefomu Le-Butt Joint Groove livuliweI-Laser Arc Composite Welding
Njengoba ukushuba kwe-workpiece eshiselwe kukhula, ukufeza ukushisela okuhlangene ohlangothini olulodwa kanye nokwakhiwa kwezinhlangothi ezimbili zamapuleti aphakathi nendawo (amandla e-laser<10 kW) ngokuvamile kuba nzima kakhulu. Ngokuvamile, amasu okushisela ahlukene adinga ukwamukelwa, njengokuklama amafomu e-groove afanelekile noma ukugcina izikhala ezithile zokudokha, ukuze kuzuzwe ukushiselwa kwamapuleti aphakathi nendawo nawugqinsi. Kodwa-ke, ekushiseleni ukukhiqizwa kwangempela, ukugcina izikhala ze-docking kuzokwandisa ubunzima bezinto zokushisela. Ngakho-ke, ukwakheka kwe-groove kuba okubalulekile ngesikhathi senqubo yokushisela. Uma ukwakheka kwe-groove kungenangqondo, ukuzinza nokusebenza kahle kwe-welding kuzothinteka kabi, futhi kwandisa ingozi yokukhubazeka kwe-welding.
(1) Ifomu le-groove lithinta ngqo ikhwalithi ye-weld seam. Idizayini efanelekile ye-groove ingaqinisekisa ukuthi insimbi yensimbi yokushisela igcwaliswe ngokugcwele kumthungo we-weld, inciphise ukwenzeka kokulimala kokushisela.
(2) Umumo wejiyomethri we-groove uthinta indlela ukushisa okudluliselwa ngayo, okungaqondisa kangcono ukushisa, ukuzuza ukushisisa okufanayo nokupholisa okufanayo, futhi kusize ukugwema ukuwohloka kokushisa nokucindezeleka okusalayo.
(3) Ifomu le-groove lizothinta i-cross-sectional morphology ye-weld seam, futhi kuzoholela ekutheni i-cross-sectional morphology ye-weld seam ihambisane kakhulu nezidingo ezithile, njengokushona kokungena kwe-weld nobubanzi.
(4) Ifomu elifanele le-groove lingathuthukisa ukuzinza kwe-welding futhi linciphise izenzakalo ezingazinzile ngesikhathi senqubo yokushisela, njengokuchaphaza kanye nokukhubazeka okungaphansi.
Njengoba kuboniswe kuMfanekiso 3, abacwaningi bathole ukuthi ukusebenzisa i-laser arc composite welding (amandla e-laser 4kW) kungagcwalisa inkatho ngezingqimba ezimbili kanye nokudlula okubili, ukuthuthukisa ngempumelelo ukusebenza kahle kwe-welding; I-welding yamahhala ye-MnDR engu-20mm ewugqinsi yazuzwa kusetshenziswa i-laser arc composite welding enezingqimba ezintathu (amandla e-laser angu-6kW); I-laser arc composite welding yasetshenziselwa ukushisela insimbi enekhabhoni ewugqinsi engu-30mm ezingxenyeni eziningi namaphasi, futhi i-morphology yesigaba esiphambanayo yelunga elishiselwe yayizinzile futhi iyinhle. Ngaphezu kwalokho, abacwaningi bathole ukuthi ububanzi bemifantu engunxande kanye ne-engeli yemisele emise okuka-Y kunomthelela omkhulu kumphumela wokuvinjwa kwendawo. Lapho ububanzi groove elingunxande kuyinto≤4mm futhi i-engeli ye-groove emise okuka-Y ingu-≤60 °, i-cross-section morphology ye-weld seam ibonisa imifantu emaphakathi kanye nezinotshi zezindonga eziseceleni, njengoba kuboniswe emfanekisweni.

05 Isifinyezo
Ukukhethwa kwefomu le-groove kudinga ukucabangela ngokugcwele izidingo zomsebenzi wokushisela, izici ezibonakalayo, kanye nezici zenqubo ye-laser arc composite welding. Idizayini efanele ye-groove ingathuthukisa ukusebenza kahle kwe-welding futhi inciphise ubungozi bokukhubazeka kokushisela. Ngakho-ke, ukukhethwa nokuklama kwefomu le-groove kuyisici esibalulekile ngaphambi kwe-laser arc composite welding yamapuleti aphakathi nendawo nawugqinsi.
