Kukanganisa kwakajairika uye kudzivirira welded pombi

Kukanganisa kunogadzirwa mukugadzirwa chaiko kwepombi dzepamusoro-frequency welded (astm a53 giredhi b erw pombi) dzimwe nguva hazvikonzerwi nechikonzero chimwe chete, asi kazhinji mhedzisiro yekubatanidzwa kwezvinhu zvakawanda.Welding defects inogonawo kukonzerwa nezvimwe zvikonzero kunze kwenzvimbo yewelding, saka zvinhu zvakawanda zvinofanirwa kutariswa zvakakwana kune hurema , Dambudziko rinogona kugadziriswa chete nekunyatsoongorora zvikonzero.

Inclusions

Magadzirirwo ekugadzirisa kukanganisa ndeyekuti simbi oxide haina extruded nesimbi yakanyungudutswa, asi inoiswa sandwiched pamusoro welding.

Aya esimbi okisisi anowanzo kuumbwa pamusoro pesimbi yakanyungudutswa pakona yeV.Kana mupendero wemupendero unosvika pakumhanya wakadzikira pane kumhanya kwekunyunguduka, uye kukurumidza kunyunguduka kwakakwira kupfuura kumhanya kwekuyerera kwesimbi yakanyungudutswa, iyo yepamusoro yekuvhura-yakaita V inovhura simbi yakanyungudutswa uye Kuiswa kwesimbi oxides hakugone kuve kwakakwana. kuburitswa mushure memazuva ese extrusion.Kumusoro kwesimbi yakachena mhinduro inoputirwa neaya esimbi okisi, nokudaro kuumba hurema mukugadzira uye welding process.

Ichi chikanganiso chichaita kuti weld iparadze mushure mekugadzirisa, uye inclusions ichaonekwa pakuputsika kweweld.Ichi chikanganiso chiripo nenzira dzakasiyana, dzimwe nguva imwe chete, dzimwe nguva mucheni.

Matanho ekudzivirira ekubatanidza kukanganisa:

1. Iyo V-yakaita angle inodzorwa mukati me4 ~ 6
2. Kugadziriswa kweyuniti kuti ive nechokwadi chakagadzikana chekuvhura angle kureba
3. Chiyero cheMn/Si mumakemikari emutsetse mukuru kudarika 8:1
4. Deredza oxidation yenzvimbo yewelding

Pre-arc

Iri rudzi rwehurema hahuna kukwana fusion inokonzerwa ne pre-arc.Kazhinji, iyo burr kana oxide chiyero uye ngura pamucheto wemutsetse inogadzira zambuko pamberi pepamusoro pekona yeV, izvo zvinoita kuti pfupi pfupi iite kuti ikozvino kusvetuka uye kugadzira pre-arc phenomenon, uye pfupi-dunhu. ikozvino inoshandura hutungamiri huripo uye inoderedza Kupisa pakona yeV kunoderedzwa.

Kukanganisa kunokonzerwa nekuvharika kwepakarepo, kupenya uye kwakapfava ndege yakaputsika inogona kuoneka kubva kune weld fracture, dzimwe nguva hapana strip edge burr kana oxide scale, ngura, nezvimwewo, asi yakawandisa V angle kana yakawandisa voltage inokonzeresa pre- arc phenomenon , Izvi zvinokonzerwa nekubuda kwemagetsi epamusoro pamucheto wemutsetse.

Matanho ekudzivirira e pre-arc defects:

1. Iyo V-yakaita angle inodzorwa mukati me4 ~ 6
2. Mucheto wemutsara wakachena, wakatsetseka uye hauna burrs
3. Chengetedza mvura inotonhora yakachena, chengetedza mafambiro emvura inotonhorera, uye edza kunzvenga nzira V angle.

Kusakwana fusion

Ichi chikanganiso chinokonzerwa nekuti mipendero yezvimedu zviviri inopisa asi haina kunyatsobatanidzwa, uye weld yakanaka haina kuumbwa.Chikonzero chakananga chekusakwana fusion haina kukwana kupisa panguva yewelding.Pane zvakawanda zvine hukama zvinhu zvinotungamira mukusakwana welding kupisa, senge yakakwira-frequency simba.Iyo inobuda, V angle uye kureba kwekudziya, chinzvimbo chegineti bar, mamiriro ekushanda uye kutonhora kwegineti bar, saizi yeiyo induction coil, kumhanya kwewelding, nezvimwe, zvinhu izvi zvinopesvedzera mumwe nemumwe, uye mhedzisiro yakabatanidzwa. zvinotungamirira kukuremara kwakadaro.

Matanho ekudzivirira ekusakwana kwekukanganisa kwefusion:

1. Kufananidzwa kwewelding yekupinza kupisa uye welding kumhanya, maitiro eiyo mbishi zvinhu zvechubhu isina chinhu.
2. Mamiriro ekushanda emagnetic bar
3. V kona uye kureba kwekudziya
4. Induction coil tsanangudzo

Kugadzikana uye mamiriro akanaka emidziyo ndiyo mamiriro ekutanga ekudzivirira kukanganisa.Kunyatsoita kurekodha uye kuongororwa kwemaitiro parameters kunogona kuwedzera kunaka kwepombi.
