Weld pombi weld porosity haingokanganisa kusimba kwepombi chete, zvinokonzeresa kuti pombi inodonhedza uye kuora kunokonzereswa kunoderedza zvakanyanya kusimba kweweld uye kuoma.Zvinhu weld porosity ndezvi: kuyerera mumvura, tsvina, oxide uye mafirita esimbi, welding zvinongedzo uye kuvhara kwevhavha, pamusoro pemhando yesimbi uye simbi padivi mahwendefa kugadzirisa, welding tekinoroji uye simbi yekuumba maitiro.

Matanho ekudzivirira anoenderana:

1. Flux ingredients.CaF2 uye SiO2 ine huwandu hwakakodzera hwewelding, iyo reaction inotora huwandu hukuru hweH2, ichigadzira kugadzikana kwakanyanya kweHF isinganyunguriki musimbi yemvura, nekudaro ichidzivirira kuumbwa kwemakomba ehydrogen gasi.

2. Ukobvu hwakawanda hwekuyerera kazhinji 25-45mm, hombe solder particle size, bulk density awa inotora ukobvu hwepamusoro, nepo kukosha kwepasi;yakakwira ikozvino, yakaderera welding yekumhanyisa kuunganidza inotora iyo yakakura ukobvu, nepo iyo shoma kukosha kwekuwedzera, zhizha kana mhepo humidity, flux kupora kunofanirwa kuomeswa usati washandiswa.

3. Pepa resimbi rakagadzirwa nepamusoro.Kuti udzivise kuvhurika-bhuku kuyera kubva kune oxide sikeri uye mamwe marara mukati mekugadzira maitiro, bhodhi rinofanira kusetwa yekuchenesa mudziyo.

4. Steel plate edge processing.Simbi ndiro mupendero inofanira kusetwa ngura uye burr yokubvisa mudziyo kuderedza zvinogona chizvarwa makomba.Kubvisa mudziyo wakaiswa munzvimbo yakanakisa mushure memuchina wekugaya uye disc shear, chimiro chechishandiso ndiyo inoshanda waya vhiri divi mbiri kumusoro uye pasi chinzvimbo chinogadziriswa gap, yekumusoro uye yezasi clamping plate edge.

5. Weld profile.Weld forming factor idiki kwazvo, yakamanikana uye yakadzika weld chimiro, gasi uye kubatanidza haisi nyore kubuda kunze, nyore kugadzira pores uye slag.General weld coefficient control mu 1.3-1.5, gobvu-yakakomberedzwa pombi inonyanyisa kukosha, hushoma kukosha kwehutete-madziro.

6. Kuderedza yechipiri magnetic field.Kuti uderedze pesvedzero yemagineti kuvhuvhuta kunofanira kuitwa pane workpiece welding tambo yekubatanidza nzvimbo inogoneka chete kure neanopinza terminal, kudzivirira imwe welding tambo yechipiri magineti inogadzirwa mune workpiece.

7. Kushanda.Zvinofanira kunge zvakakodzera kuderedza kana kuwedzera kumhanya welding ikozvino, nokudaro kunonoka crystallization mwero we weld simbi yekugezera kuitira kufambisa kupukunyuka kwegasi, panguva imwe chete, kana tambo yekutakura nzvimbo kusagadzikana, inofanira kugadziriswa nenguva. bvisa kazhinji kugadziridza zvakanaka mushure mekugashira ekisero yekumberi kana bhiriji kuchengetedza kuumbwa, zvichiita kuti gasi ribude zvakaoma.
