01 Gobvu ndiro laser-arc hybrid welding
Gobvu ndiro (ukobvu ≥ 20mm) welding inoita basa rinokosha mukugadzirwa kwemidziyo mikuru munzvimbo dzakakosha dzakadai semuchadenga, kufamba uye kuvaka ngarava, kutakura njanji, etc. Izvi zvikamu zvinowanzoonekwa nehupamhi hukuru, mafomu akaoma akabatanidzwa, uye basa rakaoma. nharaunda. Welding quality ine mhedzisiro yakananga pakuita uye hupenyu hwemidziyo. Nekuda kwekunonoka kumhanyisa welding uye matambudziko akakura epasptter, iyo yechinyakare gasi yakadzivirirwa welding nzira inotarisana nematambudziko senge yakaderera welding kunyatsoita, yakakwira simba rekushandisa, uye hombe yekusarira kunetseka, zvichiita kuti zviome kuzadzisa izvo zvinogara zvichiwedzera zvekugadzira zvinodiwa. Nekudaro, laser-arc hybrid welding tekinoroji yakasiyana neyechinyakare welding tekinoroji. Inobudirira kubatanidza zvakanakiralaser weldinguye arc welding, uye ine hunhu hwekudzika kwakakura kwekupinda, kukurumidza kumhanyisa kumhanya, kugona kwakanyanya uye nani weld mhando, sezvakaratidzwa muFigure 1 Ratidza. Naizvozvo, tekinoroji iyi yakwezva kutarisisa kwakapararira uye yakatanga kushandiswa mune dzimwe nzvimbo dzakakosha.
Mufananidzo 1 Nheyo yelaser-arc hybrid welding
02Tsvaga palaser-arc hybrid welding yemahwendefa akakora
The Norwegian Institute of Industrial Technology uye Lule University of Technology muSweden vakadzidza structural kufanana kweanosanganiswa welded joints pasi pe15kW ye45mm gobvu micro-alloyed high-simba rakaderera-alloy simbi. Osaka University neEgypt's Central Metallurgical Research Institute yakashandisa 20kW faibha laser kuita tsvakiridzo pa single-pass laser-arc hybrid welding process yema plates gobvu (25mm), vachishandisa yepasi liner kugadzirisa dambudziko repasi hump. Kambani yeDanish Force Technology yakashandisa maviri 16 kW disk lasers munhevedzano kuita tsvakiridzo pamusoro peiyo hybrid welding ye40mm gobvu simbi ndiro pa32 kW, zvichiratidza kuti high-power laser-arc welding inotarisirwa kushandiswa muoffshore wind power tower base welding. , sezvinoratidzwa muMufananidzo 2. Harbin Welding Co., Ltd. ndiyo yekutanga munyika kuti iite hunyanzvi hwekugadzira tekinoroji uye michina yekubatanidza tekinoroji yepamusoro-simba yakasimba laser-melting electrode arc hybrid heat source welding. Inguva yekutanga kubudirira kushandisa yakakwirira-simba yakasimba laser-dual-waya inonyungudutsa electrode arc hybrid welding tekinoroji uye zvishandiso kune yakakwirira-yekupedzisira michina munyika yangu. kugadzira.
Mufananidzo 2. Laser yekuisa marongerwo dhiyagiramu
Zvinoenderana neazvino mamiriro ekutsvagisa kwelaser-arc hybrid welding yemapuleti akakora kumba nekune dzimwe nyika, zvinogona kuoneka kuti musanganiswa welaser-arc hybrid welding nzira uye nhete gap groove inogona kugonesa welding yemahwendefa akakora. Kana simba relaser richiwedzera kusvika anopfuura zviuru gumi watts, pasi pekuvhenekerwa kwe-high-energy laser, maitiro evaporization yezvinhu, maitiro ekudyidzana pakati pelaser neplasma, iyo yakagadzikana mamiriro ekuyerera kwedziva rakanyungudutswa, nzira yekupisa yekupisa, uye. iyo metallurgical maitiro e weld Shanduko ichaitika kune akasiyana madhigirii. Sezvo simba richiwedzera kusvika kune anopfuura 10,000 watts, kuwedzera kwesimba remagetsi kuchawedzera dhigirii ye vaporization munzvimbo iri pedyo negomba duku, uye recoil simba rinokanganisa zvakananga kugadzikana kwegomba duku uye kuyerera kwedziva rakanyungudutswa. nokudaro kukanganisa welding process. Shanduko idzi dzine hunhu husina hunhu pakushandiswa kwelaser uye maitiro ayo anoumba welding. Izvi hunhu zviitiko muwelding process zvakananga kana zvisina kunanga zvinoratidza kugadzikana kwewelding process kusvika pamwero wakati, uye inogona kutoona kunaka kweweld. Iko kubatanidza mhedzisiro yeaviri ekupisa masosi e laser uye arc anogona kuita maviri ekupisa masosi kupa kutamba kwakazara kune iwo hunhu uye kuwana zvirinani welding mhedzisiro pane imwechete laser welding uye arc welding. Kuenzaniswa neiyo laser autogenous welding nzira, iyi welding nzira ine mabhenefiti eiyo gap yakasimba kuchinjika uye yakakura weldable ukobvu. Kuenzaniswa neyakamanikana gap laser waya yekuzadza welding nzira yemahwendefa akakora, ine mabhenefiti epamusoro waya yekunyunguduka kunyatsoita uye yakanaka groove fusion maitiro. . Uye zvakare, kukwezva kweiyo laser kune arc kunowedzera kugadzikana kwearc, ichiita laser-arc hybrid welding nekukurumidza kupfuura yechinyakare arc welding uye.laser filler waya welding, ine mwero welding kunyatsoshanda.
03 Yakakwirira-simba laser-arc hybrid welding application
Yakakwira-simba laser-arc hybrid welding tekinoroji inoshandiswa zvakanyanya muindasitiri yekuvaka ngarava. Meyer Shipyard kuGermany yakamisa 12kW CO2 laser-arc hybrid welding yekugadzira mutsara wewelding hull flat flat plates uye stiffeners kuti uwane kuumbwa kwe20m kureba fillet welds mune imwe kuenda uye kuderedza dhigirii re deformation ne2/3. GE yakagadzira faibha laser-arc hybrid welding system ine simba guru rinobuda 20kW kuti weld USS Saratoga inotakura ndege, ichichengetedza matani mazana masere esimbi yeweld uye kuderedza maawa emunhu ne80%, sezvakaratidzwa muFigure 3. CSSC 725 inotora a 20kW fiber laser yakakwirira-simba laser-arc hybrid welding system, iyo inogona kuderedza welding deformation ne60% uye kuwedzera welding kunyatsoshanda ne300%. Shanghai Waigaoqiao Shipyard inoshandisa 16kW faibha laser yakakwirira-simba laser-arc hybrid welding system. Mutsetse wekugadzira unotora tekinoroji nyowani yelaser hybrid welding + MAG welding kuti iwane imwe-sided single-pass welding uye yakapetwa-mativi kuumbwa kwe4-25mm gobvu simbi mahwendefa. Yakakwira-simba laser-arc hybrid welding tekinoroji inoshandiswa zvakanyanya mumotokari dzine zvombo. Hunhu hwayo hwewelding ndeiyi: welding yehukuru-hukobvu yakaoma masimbi zvimiro, yakaderera mutengo, uye yakakwirira-inoshanda kugadzira.
Mufananidzo 3. USS Sara Toga mutakuri wendege
Yakakwira-simba laser-arc hybrid welding tekinoroji yakatanga kushandiswa mune mamwe maindasitiri minda uye ichave yakakosha nzira yekugadzira inobudirira yezvivakwa zvakakura zvine madziro epakati uye makuru makubvu. Parizvino, pane kushaikwa kwekutsvagisa pamusoro pemaitiro epamusoro-simba laser-arc hybrid welding, iyo inoda kusimbiswa zvakare, sekudyidzana pakati pephotoplasma nearc uye kupindirana pakati pearc nedziva rakanyungudutswa. Pachine matambudziko mazhinji asina kugadziriswa mune yakakwirira-simba laser-arc hybrid welding process, senge yakamanikana process hwindo, isina kuenzana mechanicha zvimiro zveiyo weld chimiro, uye yakaoma welding quality control. Sezvo simba rekubuda remaindasitiri-giredhi lasers richiwedzera zvishoma nezvishoma, yakakwirira-simba laser-arc hybrid welding tekinoroji inokura nekukurumidza, uye akasiyana siyana matsva e-laser hybrid welding matekinoroji acharamba achibuda. Localization, hukuru-hukuru uye hungwaru huchave hwakakosha mafambiro mukuvandudzwa kweyepamusoro-simba laser welding michina mune ramangwana.
