Kushandiswa kwetekinoroji yekubatanidza yelaser-arc hybrid ine simba guru muminda yakasiyana-siyana yakakosha

01 Kubatanidza kwehybrid ne laser-arc plate gobvu

Kubatanidza simbi gobvu (ukobvu ≥ 20mm) kunoita basa guru mukugadzirwa kwemidziyo mikuru munzvimbo dzakakosha dzakadai sendege, kufamba nengarava, kutakurwa kwechitima, nezvimwewo. Zvikamu izvi zvinowanzoonekwa nekukora kukuru, mafomu akaomarara ekubatana, uye nzvimbo dzakaoma dzebasa. Hunhu hwekusanganisa hune chekuita zvakananga nekushanda uye hupenyu hwemidziyo. Nekuda kwekumhanya kunononoka kwekusanganisa simbi uye matambudziko akakomba ekupararira, nzira yekusanganisa simbi negesi inosangana nematambudziko akadai sekushanda zvishoma kwesimbi, kushandiswa kwesimba rakawanda, uye kushushikana kukuru, zvichiita kuti zviome kusangana nezvinodiwa zvekugadzira zviri kuramba zvichiwedzera. Nekudaro, tekinoroji yekusanganisa simbi ne laser-arc yakasiyana netekinoroji yekusanganisa simbi. Inobatanidza zvinobudirira zvakanakira zvewelding nelaseruye arc welding, uye ine hunhu hwekudzika kukuru kwekupinda, kumhanya kwewelding nekukurumidza, kushanda zvakanaka uye kunaka kweweld, sezvakaratidzwa muMufananidzo 1 Show. Nokudaro, tekinoroji iyi yakakwezva kutariswa kwevanhu vakawanda uye yakatanga kushandiswa mune dzimwe nzvimbo dzakakosha.

02Tsvagiridzo pamusoro pekusanganisa mapurasitiki akakora ne laser-arc hybrid

Sangano reNorwegian Institute of Industrial Technology neLule University of Technology muSweden vakadzidza nezvekufanana kwemajoini akasungirirwa akagadzirwa nesimbi ine simba re45mm ukobvu. Osaka University neEgypt's Central Metallurgical Research Institute vakashandisa 20kW fiber laser kuita tsvakiridzo pamusoro pe single-pass laser-arc hybrid welding process yema thick plates (25mm), vachishandisa bottom liner kugadzirisa dambudziko re bottom hump. Danish Force Technology Company yakashandisa maviri 16 kW disk lasers akatevedzana kuita tsvakiridzo pamusoro pe hybrid welding yema 40mm thick steel plates pa32 kW, zvichiratidza kuti high-power laser-arc welding inotarisirwa kushandiswa mu offshore wind power tower base welding, sezvakaratidzwa muMufananidzo 2. Harbin Welding Co., Ltd. ndiyo yekutanga munyika iyi kugona tekinoroji yepakati uye tekinoroji yekubatanidza michina ye high-power solid laser-melting electrode arc hybrid heat source welding. Ndiyo nguva yekutanga kushandisa tekinoroji yekubatanidza electrode yemhando yepamusoro ine simba guru uye michina ye laser-dual-waya inonyungudutsa arc hybrid welding kumidziyo yepamusoro-soro munyika yangu.

Mufananidzo 2. Dhayagiramu yekuisa laser

Zvichienderana nemamiriro ekutsvaga aripo pari zvino e laser-arc hybrid welding yema thick plates e laser-arc kumba nekune dzimwe nyika, zvinogona kuonekwa kuti kusanganiswa kwe laser-arc hybrid welding method uye narrow gap groove zvinogona kuita kuti ma thick plates awedzere. Kana simba re laser rikawedzera kusvika pa 10,000 watts, pasi pekupiswa kwe high-energy laser, maitiro e vaporization yezvinhu, maitiro ekudyidzana pakati pe laser ne plasma, mamiriro akagadzikana ekuyerera kwedziva rakanyungudutswa, nzira yekufambisa kupisa, uye maitiro e metallurgical e weld Kuchinja kuchaitika kusvika padanho rakasiyana. Sezvo simba richiwedzera kusvika pa 10,000 watts, kuwedzera kwesimba remagetsi kuchawedzera mwero we vaporization munzvimbo iri pedyo negomba diki, uye simba rekudzokera shure richakanganisa zvakananga kugadzikana kwegomba diki uye kuyerera kwedziva rakanyungudutswa, nokudaro zvichikanganisa maitiro e welding. Shanduko idzi dzine mhedzisiro isingakoshi pakushandiswa kwe laser uye maitiro ayo e welding akabatanidzwa. Izvi zviitiko zvinoonekwa mu welding process zvinoratidza zvakananga kana zvisina kunanga kugadzikana kwe welding process kusvika pamwero wakati, uye zvinogona kutoona mhando ye weld. Kubatana kwezvinobatidza kupisa zve laser ne arc kunogona kuita kuti zvinobatidza kupisa zviviri izvi zvipe hunhu hwazvo uye zviwane mhedzisiro iri nani ye welding pane single laser welding ne arc welding. Kana tichienzanisa ne laser autogenous welding method, iyi welding method ine zvakanakira zvekuchinjika kwe gap uye ukobvu hwakakura hwe weldable. Kana tichienzanisa ne narrow gap laser wire filling welding method yema thick plates, ine zvakanakira kushanda zvakanaka kwe wire melting uye good groove fusion effect. . Pamusoro pezvo, kukwezva kwe laser ku arc kunowedzera kugadzikana kwe arc, zvichiita kuti laser-arc hybrid welding ikurumidze kupfuura traditional arc welding uyewelding waya yekuzadza nelaser, ine kushanda zvakanaka kwewelding kwakanyanya.

03 Kushandiswa kwekubatanidza hybrid ne laser-arc ine simba guru

Tekinoroji yekubatanidza hybrid ye laser-arc ine simba guru inoshandiswa zvakanyanya muindasitiri yekuvaka ngarava. Meyer Shipyard muGermany yakagadzira mutsetse wekugadzira welding we hybrid welding we 12kW CO2 laser-arc flat plates uye stiffeners kuti pave nekuumbwa kwe 20m refu fillet welds panguva imwe chete uye kuderedza mwero we deformation ne 2/3. GE yakagadzira fiber laser-arc hybrid welding system ine simba guru re 20kW kuti isanganise USS Saratoga aircraft carrier, ichichengetedza matani 800 esimbi ye weld uye ichideredza maawa ekushanda ne 80%, sezvakaratidzwa muMufananidzo 3. CSSC 725 inoshandisa 20kW fiber laser high-power laser-arc hybrid welding system, iyo inogona kuderedza deformation ye welding ne 60% uye kuwedzera kushanda kwe welding ne 300%. Shanghai Waigaoqiao Shipyard inoshandisa 16kW fiber laser high-power laser-arc hybrid welding system. Mutsetse wekugadzira unoshandisa tekinoroji itsva ye laser hybrid welding + MAG welding kuti uwane single-sided single-pass welding uye double-sided structure yemaplate esimbi ane ukobvu hwe4-25mm. Tekinoroji ye laser-arc hybrid welding ine simba guru inoshandiswa zvakanyanya mumotokari dzehondo. Hunhu hwayo hwekushongedza ndeihu: kushongedza zvivakwa zvesimbi zvakakura, mutengo wakaderera, uye kugadzira zvinobudirira zvakanyanya.

Tekinoroji yekubatanidza hybrid yelaser-arc ine simba guru yakatanga kushandiswa mune mamwe maindasitiri uye ichave nzira yakakosha yekugadzira zvinobudirira zvivakwa zvikuru zvine ukobvu hwemadziro epakati nepakati nehukuru. Parizvino, hapana tsvakurudzo pamusoro pemaitiro ekubatanidza hybrid yelaser-arc ine simba guru, iyo inoda kusimbiswa zvakanyanya, senge kudyidzana pakati pephotoplasma nearc uye kudyidzana pakati pearc nedziva rakanyungudutswa. Kuchine matambudziko mazhinji asina kugadziriswa mukuita kwekubatanidza hybrid yelaser-arc ine simba guru, senge hwindo rekuita rakamanikana, hunhu husina kuenzana hwechimiro cheweld, uye kudzora kwakaoma kwewelding. Sezvo simba rekubudisa rema laser emhando yepamusoro richikwira zvishoma nezvishoma, tekinoroji yekubatanidza hybrid yelaser-arc ine simba guru ichakura nekukurumidza, uye matekinoroji matsva ekubatanidza hybrid yelaser acharamba achibuda. Kuisa munzvimbo, hukuru uye hunyanzvi zvichave mafambiro akakosha mukuvandudzwa kwemidziyo yekubatanidza yelaser ine simba guru mune ramangwana.
