1. Deredzai kushushikana kwekushushikana Kwepfungwa yekushushikana kweiyo kuneta kuputika sosi pane welded joint uye magadzirirwo, uye nzira dzese dzekubvisa kana kudzikisa kushushikana kwepfungwa dzinogona kuvandudza simba rekuneta kwechimiro.
(1) Gamuchira fomu inonzwisisika yemaitiro
① Majoini ebhut anosarudzwa, uye majoini emakumbo haashandiswe zvakanyanya sezvinobvira;Majoini akafanana neT kana majoini emakona anoshandurwa kuita majoini ebutt muzvikamu zvakakosha, kuitira kuti welds adzivise makona;apo majoini akafanana neT kana majoini emakona anoshandiswa, zvinotarisirwa kushandisa zvizere kupinda butt welds.
② Edza kudzivirira dhizaini yekurodha eccentric, kuitira kuti simba remukati renhengo rinogona kufambiswa zvakanaka uye zvakaenzana kugovaniswa pasina kukonzera kuwedzera kushushikana.
③Kuderedza kungoerekana kwachinja kwechikamu, kana hupamhi hweplate kana hupamhi hwakasiyana zvakanyanya uye huchida kuiswa, nzvimbo yekuchinja yakapfava inofanira kugadzirwa;iyo kona yakapinza kana kona yechigadziro inofanira kuitwa kuva arc shape, uye yakakura radius ye curvature, zviri nani.
④Dzivisa nzira nhatu dzinopinda munzvimbo, edza kusaisa welds munzvimbo dzekushushikana, uye edza kusaisa transverse welds panhengo huru dzemakakatanwa;kana zvisingadzivisiki, mukati uye kunze kwehutano hwe weld hunofanira kuvimbiswa, uye weld toe inofanira kuderedzwa.stress concentration.
⑤Kune mabheti welds anogona kungobatanidzwa kune rumwe rutivi, hazvibvumirwi kuisa mahwendefa ekutsigira kumashure mune zvakakosha zvivako;dzivisa kushandisa intermittent welds, nokuti kune kunyanya kunetseka kwepamusoro pakutanga uye kupera kweweld imwe neimwe.
(2).Yakarurama weld chimiro uye yakanaka weld mukati nekunze kwemhando
① Kureba kwasara kwebutt joint weld kunofanirwa kunge kuri kudiki sezvinobvira, uye zvakanakisa kubhururuka (kana kugaya) rakati sandara mushure mewelding pasina kusiya hurefu hwasara;
② Zvakanakisisa kushandisa fillet welds ine concave surfaces yeT-shaped joints, pasina fillet welds ine convexity;
③ Chigunwe chiri panosangana weld uye chigadziko chesimbi chinofanirwa kufambiswa zvakanaka, uye chigunwe chinofanirwa kunge chiri pasi kana argon arc yakanyungudutswa kana zvichidikanwa kuti uderedze kushushikana uko.
Zvese zvinokanganisa welding zvine madhigirii akasiyana ekusimbisa kushushikana, kunyanya flake welding defects, senge makatsemuka, kusapinda, kusiri-fusion uye kumucheto kuruma, nezvimwewo, zvine simba guru pakusimba kwekuneta.Naizvozvo, mukugadzirwa kwemaitiro, zvinodikanwa kuve nechokwadi chekuti weld imwe neimwe iri nyore kubatanidza, kuitira kuti uderedze hurema hwekushongedza, uye hurema hunodarika mwero hunofanira kubviswa.
2.Rongedza kushushikana kwasara
Iyo yakasara yekumanikidza kushushikana pamusoro peiyo nhengo kana kushushikana kwekumanikidza kunogona kuvandudza kuneta kusimba kweiyo welded chimiro.Semuenzaniso, nekugadzirisa kutevedzana kwewelding uye kupisa kwenzvimbo, zvinokwanisika kuwana nzvimbo yakasara yekushushikana iyo inobatsira kuvandudza simba rekuneta.Pamusoro pezvo, kusimbaradza kwepamusoro, sekuumburudza, kusando kana kupfurwa, kunogonawo kugamuchirwa kugadzira simbi yepasi pepurasitiki deformation uye kuomesa, uye kuburitsa yakasara yekumanikidza kudzvinyirira muchikamu chepamusoro kuti uwane chinangwa chekuvandudza simba rekuneta.
Iyo yakasara yekumanikidza kushushikana pamusoro peiyo notch inogona kuwanikwa nekushandisa imwe-nguva pre-yakawandisa kutambanudza kune iyo noted nhengo.Izvi zvinodaro nekuti chiratidzo cheiyo notch yakasara kushushikana mushure mekurodha elastic inogara ichipesana nechiratidzo cheiyo notch stress panguva (elastoplastic) kurodha.Iyi nzira haina kukodzera kukotamisa kuremerwa kana akawanda tensile kurodha.Inowanzo kusanganiswa nemaitiro ekugamuchira bvunzo, senge midziyo yekumanikidza ye hydraulic bvunzo, inogona kutamba pre-yakawandisa tensile basa.
3.Kuvandudza chimiro uye maitiro ezvinyorwa
Chekutanga pane zvese, kuvandudza simba rekuneta kwesimbi yesimbi uye weld simbi inofanirwawo kutariswa kubva kune yemukati mhando yezvinhu.Iyo metallurgical quality yezvinhu inofanira kuvandudzwa kuderedza kubatanidzwa mairi.Zvikamu zvakakosha zvinogona kugadzirwa kubva kuzvinhu zvekunyungudusa maitiro senge vacuum melting, vacuum degassing, uye kunyange electroslag remelting kuve nechokwadi kuchena;Hupenyu hwekuneta kwesimbi yezviyo hunogona kuvandudzwa nekunatswa patembiricha yekamuri.Iyo yakanakisa microstructure inogona kuwanikwa nekupisa kurapwa, uye iyo plastiki uye kuoma kunogona kuvandudzwa uku simba richiwedzerwa.Tempered martensite, yakaderera kabhoni martensite uye yakaderera bainite ine yakanyanya kuneta kuramba.Chechipiri, simba, plastiki uye kuoma kunofanirwa kuenderana.Kusimba ndiko kugona kwechinhu kuramba kutyora, asi yakakwirira-simba zvinhu zvinonzwa kune notches.Basa guru repurasitiki nderekuti kuburikidza nepurasitiki deformation, deformation basa rinogona kunyura, kushungurudzika kwepamusoro kunogona kuderedzwa, kushushikana kwakanyanya kunogona kugoverwazve, uye notch uye muromo wekuputika unogona kupfuudzwa, uye kuwedzera kwekuputika kunogona kuderedzwa kana kunyange kumira.Plastiki inogona kuve nechokwadi chekuti kusimba kwekutamba kwakazara.Nokudaro, nokuda kwesimbi yakakwirira-yakasimba uye simbi yepamusoro-yakasimba, kuedza kuvandudza zvishoma zvepurasitiki uye kuoma kuchavandudza zvakanyanya kuneta kwayo.
4.Zviyero zvakakosha zvekudzivirira
Atmospheric medium erosion inowanzokonzera kuneta kwesimba remidziyo, saka zvinobatsira kushandisa imwe yekudzivirira yekudzivirira.Semuyenzaniso, kupfekedza chitubu chepurasitiki chine mafiritsi panguva dzekushushikana inzira inoshanda yekuvandudza.
