Platform welding inoda zvinopfuura kungopisa uye filler simbi. Ndiko uko kutendeseka kwechimiro kunosangana nemakwara epasirese epasirese-apo isina kurongeka tack weld inogona kuwira mukudhura rework, kunonoka kutumwa, kana zvakatoipisisa, kutadza kwemunda pasi pekunetseka kwecyclic. KuBotou Haijun Metal Products Co., Ltd., takaita zvinopfuura zviuru gumi nezviviri zvemapuratifomu welding sequences kuyambuka chassis yekurima, mafuremu emidziyo yekuvaka, uye otomatiki ekutsigira conveyor zvivakwa. Zvatakadzidza hazvisi zvekufungidzira: zvakamisikidzwa mumishumo yedu yeDFM, kupisa-kuburikidza nematanda, uye mushure-weld kukanganisa kuyerwa.
Pre-Weld Preparation Haisi-Kukurukurirana-Haisi Optional
Mazhinji kutadza kweplatform welding kunotanga arc isati yarova. Isu tinozviona kakawanda: zvikwata zvinosvetuka-svetuka kubatanidza kuenderana, kufungidzira kupfava kwezvinhu, kana kufuratira kusiyanisa kweguyo-pachiyero pamabhechi esimbi. Panzvimbo yedu yeBotou, gungano rega rega repuratifomu rinotanga nemacheki matatu asingagone kutaurirana:
Gap kushivirira ≤ 0.5 mm kuyambuka hurefu hwakazara hwemajoini-kuyerwa nemafeeker geji *pamberi* kusungirira, kwete mushure Base simbi tembiricha ≥ 10°C munzvimbo dzinotonhora; pazasi pacho, preheat kusvika 50°C yecarbon steel, 100°C ye304 stainless-inosimbiswa neinfrared thermometers pamapoinzi matatu pamita. Kuchena kwepamusoro kwakasimbiswa ne solvent pukuta + chena jira bvunzo: hapana chinosara chinooneka, hapana mafuta emunwe, hapana guruva rinokuya rakavharirwa mumakoronga Takamborasa magungano 17 emabhuraketi nekuti batch rimwe chete resimbi inotonhora rakasvika riine ukobvu hweguyo husingaenderani. Iyo oxide layer yakatsemuka zvisina kuenzana panguva yeGMAW, zvichikonzera micro-porosity mumidzi inopfuura. Ikozvino, macoil ese anouya anotariswa spectral kuongororwa kwepamusoro oxide kufanana-uye isu tinogadzirisa inodzivirira gasi kuyerera (kubva pa18 L/min kusvika 22 L/min) apo mutsauko unodarika ± 0.3 µm.
Kusarudzwa kweMaitiro Kunoraira Kuita Kwemaitiro
Kusarudza pakati peFCAW, GMAW, neSAW haisi yekumhanyisa - ndeyekufananidza kupinza kwemafuta kune geometry, ukobvu hwezvinhu, uye kurodha sevhisi. Kune zvivakwa zvepuratifomu zvine ≥6 mm kukora kwemadziro uye anoenderera mberi fillet majoini, isu tinogara tichiita flux-cored arc welding tichishandisa E71T-1 waya. Sei? Yayo slag system inoshivirira kudiki-up kusiyanisa zviri nani pane waya yakasimba, uye yakakwirira deposition rate inocheka nzvimbo ine kupisa-inotapukira (HAZ) hupamhi ne22% maringe neGMAW payakafanana amperage.
Asi kune dzakatetepa-geji mapuratifomu - senge aruminiyamu ekutsigira madhizaini ekumisikidza solar masisitimu - isu tinochinja kune pulsed GMAW ine 1.2 mm ER5356 waya. Pulse frequency inogara pa120 Hz; peak current yakavharwa pa145 A. Izvi zvinodzivirira kupisa-kuburikidza pamashizha e2.5 mm uchichengetedza kudzika kwekupinda ≥1.8 mm. Vamwe vanogona kupokana kuti MIG "iri nyore" kune aluminium. Nekudaro, pasina kudzora pulse, takayera 37% yepamusoro yekukanganisa mazinga uye 4 × yakawanda porosity mumamiriro ehunyoro-yakasimbiswa kuburikidza neradiographic kuyedzwa pa120 sampuro welds.
Clamping Strategy Inosarudza Dimensional Kugadzikana
Maclamps haabate zvikamu-anodzora kusara kunetseka. Chiitiko chedu chakaipisisa papuratifomu yehondo chakaitika pa 3.2-mita yekurima furemu: nhanhatu dzakaenzana dzakaparadzana C-clamps dzakagadzira kuzvidzora kwenzvimbo, kumanikidza kukanganisa kunze pakati penguva. Isu zvino tinoshandisa sequential clamping: tanga gadzirisa datum edges, wobva waisa zvibatiso zvinoyangarara pa300-mm nhanho pamwe neasiri-datum flanges, tichiburitsa imwe neimwe clamp *mushure me* iyo yepedyo weld inotonhora kusvika 60 ° C. Makamera anopisa anosimbisa izvi zvinoderedza kukanganiswa kweangular ne 65% kupesana ne static clamping.
Isu takabatidzawo strain-relief slots-0.8 mm yakafara, akachekwa nelaser-pamwe nepamusoro-stress transition zones. Aya anoita seanodzorwa anodzora kusagadzikana nzira panguva yekutonhora. Mune chimwe chikuva chemidziyo yekuvaka, kuwedzera matatu 12-mm slots yakaderedza post-weld kutwasanuka kubva pa2.1 mm/m kusvika 0.4 mm/m-pasina post-weld machining.
Kuongorora Kunofanira Kupfuura Kunooneka Cheki
Kuongorora kwekuona kunobata chete 41% yekukanganisa kwakakomba mumapuratifomu welds, zvinoenderana neyemukati NDT data kubva 2022-2023. Tinoda ongororo yezvikamu zvitatu:
Real-time monitoring: Ese marobhoti welding maseru log voltage, ikozvino, kumhanya kwekufamba, uye waya yekudyisa mwero pachikamu che50 mm. Kutsauka> ± 3% kunokonzeresa kumbomira otomatiki Post-weld dimensional kusimbiswa: Yese puratifomu inosangana neCMM scanning inopesana neCAD modhi-tarisa pane yakakosha buri mapatani, ine chigaro flatness (≤0.08 mm), uye weld gumbo kusachinja-chinja (± 0.3 mm) Kushanda mutoro wekuedza: Random 5% yemabheji ekugadzira anotsungirira 1.5 × yakayerwa mutoro we120 masekonzi. Isu tinoyera kutsauka pamapoinzi masere - kwete kungogumira, asi gradient pane iyo chimiro Chirango ichi chakabata nyaya yaidzokororwa mumabhuraketi akadzika-anodhonzwa: chitarisiko chinogamuchirika chakavharwa kushaikwa kwekusanganisa panosangana radius uye flange. Ultrasonic kuyedzwa kwakaratidza 92% yeakadaro welds aive ne subsurface discontinuities. Isu takagadziridza jiometry yejoints - tichiwedzera 0.5 mm midzi kumeso uye kuderedza kwaisanganisira angle kubva 75 ° kusvika 65 ° - uye kubvisa kukanganisa.
Platform Welding Is a System-Haisi Danho
Platform welding inobudirira chete kana dhizaini, kusarudzwa kwezvinhu, fixture engineering, process control, uye ongororo inoshanda senge system imwe. KuBotou Haijun, tinobata chikuva chega chega sechinhu chinotakura zvinhu—kwete muunganidzwa wezvikamu zvakakandwa. Yedu ISO-inoenderana nekufambiswa kwebasa inodzika DFM mhinduro * isati yatora* makotesheni, weld maitiro ekufanirwa * pamberi * kuburitswa kwechishandiso, uye anoteedzera zvinhu certs *nezvese zvinotumirwa*. Hatitengesi welds. Isu tinoburitsa yakasimbiswa structural kuenderera mberi.
Kune mainjiniya anotsanangudza simbi yepuratifomu, tanga pano: tsanangura nzira yekuremedza kutanga, wobva wasarudza majoyometry ejomethri, wozofananidza maitiro kune metallurgy-kwete zvakadzokera kumashure. Iko kushanduka kwega kunocheka rework ne38%, zvichibva pa2023 data kubva ku47 mapurojekiti evatengi. Platform welding haisi yekubatanidza simbi. Izvo ndezvekuvimbisa kutapurirana kwesimba-mumwaka wese, pakuchinjana, mumakumi emakore.
