01 Ipuleti eliwugqinsi we-laser-arc hybrid welding
Ipuleti eliwugqinsi (ukuqina ≥ 20mm) ukushisela kudlala indima ebalulekile ekwenziweni kwemishini emikhulu emikhakheni ebalulekile efana ne-aerospace, ukuzulazula nokwakhiwa kwemikhumbi, ezokuthutha ngesitimela, njll. Lezi zingxenye zivame ukubonakala ngobukhulu obukhulu, amafomu ahlangene ayinkimbinkimbi, kanye nenkonzo eyinkimbinkimbi. izindawo. Ikhwalithi yokushisela inomthelela oqondile ekusebenzeni nempilo yemishini. Ngenxa yejubane eliphansi lokushisela kanye nezinkinga ezinkulu ze-spatter, indlela yokushisela evikelekile yegesi ibhekene nezinselelo ezifana nokusebenza kahle kokushisela, ukusetshenziswa kwamandla okuphezulu, kanye nengcindezi enkulu eyinsalela, okwenza kube nzima ukuhlangabezana nezidingo zokukhiqiza ezilokhu zikhula njalo. Kodwa-ke, ubuchwepheshe be-laser-arc hybrid welding buhlukile kubuchwepheshe bendabuko bokushisela. Ihlanganisa ngempumelelo izinzuzo zelaser weldingkanye ne-arc welding, futhi inezici zokujula okukhulu kokungena, isivinini sokushisela esisheshayo, ukusebenza kahle okuphezulu kanye nekhwalithi engcono yokushisela, njengoba kuboniswe kuMfanekiso 1 Bonisa. Ngakho-ke, lobu buchwepheshe budonse ukunakwa okusabalele futhi sebuqale ukusetshenziswa kwezinye izindawo ezibalulekile.
Umfanekiso 1 Isimiso se-laser-arc hybrid welding
02Cwaninga nge-laser-arc hybrid welding yamapuleti awugqinsi
I-Norwegian Institute of Industrial Technology kanye ne-Lule University of Technology eSweden bafunde ukufana kwesakhiwo kwamajoyinti ayinhlanganisela ashiselwe ngaphansi kuka-15kW kwensimbi engu-45mm micro-alloyed high-power low-alloy steel. Inyuvesi yase-Osaka kanye ne-Central Metallurgical Research Institute yase-Egypt basebenzise i-laser yefayibha engu-20kW ukwenza ucwaningo ngenqubo yokushisela eyi-single-pass laser-arc hybrid yamapuleti awugqinsi (25mm), kusetshenziswa umugqa ongezansi ukuxazulula inkinga ye-hump engezansi. I-Danish Force Technology Company isebenzise ama-laser amabili e-disk angu-16 kW ochungechungeni ukwenza ucwaningo mayelana nokushisela okuhlanganisiwe kwamapuleti ensimbi angu-40mm awugqinsi angu-32 kW, okubonisa ukuthi ukushisela kwe-laser-arc enamandla amakhulu kulindeleke ukuthi kusetshenziswe ekushiseleleni isisekelo somoya osogwini. , njengoba kuboniswe kuMfanekiso 2. I-Harbin Welding Co., Ltd. ingeyokuqala ezweni ukwazi kahle ubuchwepheshe obuyisisekelo nobuchwepheshe bokuhlanganiswa kwemishini yokushisela okuqinile okuqinile kwe-laser-melting electrode arc hybrid umthombo wokushisa. Kungokokuqala ngqa ukusebenzisa ngempumelelo ubuchwepheshe bokushisela obuqinile be-laser-dual-wire encibilikisa amandla aphezulu we-arc hybrid kanye nemishini kumishini yezinga eliphezulu ezweni lami. ukukhiqiza.
Umfanekiso 2. Umdwebo wesakhiwo sokufakwa kwe-laser
Ngokwesimo samanje socwaningo se-laser-arc hybrid welding yamapuleti awugqinsi ekhaya naphesheya, kungabonakala ukuthi inhlanganisela ye-laser-arc hybrid welding method kanye ne-gap groove ewumngcingo ingafinyelela ukushiselwa kwamapuleti awugqinsi. Lapho amandla e-laser enyuka abe ngaphezu kwama-watts angu-10,000, ngaphansi kokushiswa kwelaser enamandla amakhulu, ukuziphatha kokuhwamuka kwezinto ezibonakalayo, inqubo yokusebenzisana phakathi kwe-laser ne-plasma, isimo esizinzile sokugeleza kwechibi elincibilikisiwe, indlela yokudlulisa ukushisa, kanye ukuziphatha kwe-metallurgical of the weld Izinguquko zizokwenzeka ngamazinga ahlukahlukene. Njengoba amandla enyuka abe ngaphezu kwama-watts angu-10,000, ukwanda komthamo wamandla kuzoqinisa izinga lokuhwamuka endaweni eseduze nomgodi omncane, futhi amandla okubuyela emuva azothinta ngokuqondile ukuzinza kwembobo encane nokugeleza kwechibi elincibilikisiwe, ngaleyo ndlela kuthinte inqubo yokushisela. Izinguquko zinomthelela ongenakuqhathaniswa ekusetshenzisweni kwe-laser kanye nezinqubo zayo zokushisela eziyinhlanganisela. Lezi zenzakalo zesici enqubweni yokushisela ngokuqondile noma ngokungaqondile zibonisa ukuzinza kwenqubo yokushisela ngezinga elithile, futhi zinganquma ngisho nekhwalithi ye-weld. Umthelela wokuhlanganisa wemithombo yokushisa emibili ye-laser ne-arc ungenza imithombo yokushisa emibili inikeze ukudlala okugcwele ezicini zayo futhi ithole imiphumela engcono yokushisela kune-laser welding eyodwa kanye ne-arc welding. Uma kuqhathaniswa ne-laser autogenous welding method, le ndlela yokushisela inezinzuzo zokuguquguquka kwegebe eliqinile kanye nokuqina okukhulu okushiselwayo. Uma kuqhathaniswa negebe elincane le-laser wire filling welding indlela yamapuleti awugqinsi, inezinzuzo zokusebenza kahle kokuncibilika kwezintambo kanye nomphumela omuhle wokuhlanganisa i-groove. . Ngaphezu kwalokho, ukukhangwa kwe-laser ku-arc kuthuthukisa ukuzinza kwe-arc, okwenza i-laser-arc hybrid welding isheshe kune-welding yendabuko ye-arc futhii-laser filler wire welding, ngokusebenza kahle kwe-welding ephezulu.
03 Isicelo sokushisela i-laser-arc hybrid enamandla amakhulu
Ubuchwepheshe bokushisela obunamandla amakhulu we-laser-arc hybrid busetshenziswa kakhulu embonini yokwakha umkhumbi. I-Meyer Shipyard eJalimane isungule umugqa wokukhiqiza we-12kW CO2 we-laser-arc hybrid welding wokushisela amapuleti ayisicaba nama-stiffener ukuze kuzuzwe ukwakheka kwama-welds amade angama-20m ngesikhathi esisodwa futhi kuncishiswe izinga lokuwohloka ngo-2/3. I-GE ithuthukise isistimu yokushisela i-fiber laser-arc hybrid enamandla okukhipha amandla angu-20kW ukushisela inkampani yendiza ye-USS Saratoga, yonga amathani angu-800 ensimbi yokushisela futhi yehlisa amahora okusebenza ngo-80%, njengoba kukhonjisiwe kuMfanekiso 3. I-CSSC 725 isebenzisa i- 20kW i-fiber laser high-power laser-arc hybrid welding system, enganciphisa ukuwohloka kokushisela ngo-60% futhi kwandise ukusebenza kahle kokushisela ngo-300%. I-Shanghai Waigaoqiao Shipyard isebenzisa i-16kW fiber laser high-power laser-arc hybrid welding system. Ulayini wokukhiqiza wamukela ubuchwepheshe obusha benqubo ye-laser hybrid welding + MAG welding ukuze kuzuzwe ukushiselwa kwe-single-pass-single kanye nokwakhiwa okuhlangene kwamapuleti ensimbi angu-4-25mm. Ubuchwepheshe bokushisela obunamandla amakhulu we-laser-arc hybrid busetshenziswa kakhulu ezimotweni ezihlomile. Izici zayo zokushisela yilezi: ukushiselwa kwezakhiwo zensimbi ezinobukhulu obukhulu, izindleko eziphansi, kanye nokukhiqiza okusezingeni eliphezulu.
Umfanekiso 3. USS Sara Toga umthwali wendiza
Ubuchwepheshe bokushisela i-laser-arc hybrid welding enamandla amakhulu buqale ukusetshenziswa emikhakheni yezimboni futhi buzoba yindlela ebalulekile yokukhiqiza izakhiwo ezinkulu ezinobukhulu obuphakathi nobukhulu bezindonga. Njengamanje, kukhona ukuntuleka kocwaningo mayelana nendlela ye-laser-arc hybrid welding enamandla amakhulu, okudingeka iqiniswe ngokwengeziwe, njengokusebenzelana phakathi kwe-photoplasma ne-arc kanye nokuxhumana phakathi kwe-arc nechibi elincibilikisiwe. Kusenezinkinga eziningi ezingakaxazululwa kunqubo yokushisela ye-laser-arc hybrid enamandla amakhulu, njengefasitela lenqubo elincane, izakhiwo ezingalingani zemishini yesakhiwo sokushisela, nokulawula ikhwalithi yokushisela okuyinkimbinkimbi. Njengoba amandla okukhipha ama-laser ebanga lezimboni akhula kancane kancane, ubuchwepheshe bokushisela obunamandla be-laser-arc hybrid buzokhula ngokushesha, futhi nobuchwepheshe obusha bokushisela be-laser hybrid buzoqhubeka buvela. Ukwenziwa kwasendaweni, ngezinga elikhulu kanye nobuhlakani kuzoba izitayela ezibalulekile ekuthuthukisweni kwemishini yokushisela ye-laser enamandla amakhulu esikhathini esizayo.
