Welded simbi pombiinokamurwa kuita mhando mbiri maererano yayo welding musono chimiro-yakatwasuka musono simbi pombi uye spiral simbi pombi.

Simbi pombi musono porosity haikanganisi chete kuwanda kwepombi welds, zvichikonzera kudonha kwepombi, uye inozova nzvimbo yekuora-inokonzeresa, ichideredza zvakanyanya kusimba kweweld uye kuoma.

Weld porosity zvinhu ndezvi: kuyerera kwemvura, tsvina, uye iron oxide, ukobvu hwezvinhu zvakashongedzwa uye kufukidzwa, uye nepamusoro pemhando yesimbi shizha kugadzira mativi mahwendefa, welding process uye pombi kuumba maitiro uye zvichingodaro.

Matanho ekudzora akakodzera ndeaya pazasi:

1.A flux component.Kana iine huwandu hwakakodzera hweCaF2 neSiO2, iyo welding process inotora huwandu hwakakura hweH2, uye inogadzira HF iyo ine kugadzikana kwepamusoro uye isinganyungudike mumvura yesimbi, nekudaro kudzivirira kuumbwa kwehydrogen gasi. makomba.

2.Kuunganidza ukobvu hwekuyerera kunowanzoita 25-45mm. Kana Flux iine zvidimbu zvihombe dhigirii uye diki density, tora iyo yakanyanya kuunganidzwa ukobvu, nepo kukosha kushoma;yakakwira ikozvino, yakaderera welding kumhanya inotora iyo yakanyanya ukobvu, nepo iyo shoma kukosha.Kunze kwezvo, kana muzhizha kana mazuva ekunyorova kwakanyanya, kudzoreredza kwekuyerera kunofanirwa kuomeswa usati washandiswa.

3 Steel pamusoro kurapwa.Kuti udzivise kunyunguduka kubva kune iron oxide uye imwe marara inowira mukuumbwa, mudziyo wekuchenesa bhodhi unofanirwa kumiswa.

4 Steel ndiro kumucheto kurapwa.Rust uye maburrs ekubvisa mudziyo unofanirwa kuiswa mupendero yesimbi kudzikisa mukana wekugadzira porosity.Nzvimbo yakanakisa yekuisa iyo yakajeka mudziyo iri padhuze nedhisiki yekucheka kumucheto milling michina, chimiro chemudziyo chinoshanda waya vhiri apo maviri chinzvimbo chinochinjika gap pasi, kumusoro uye pasi pasi pekumanikidza ndiro kumicheto.

5 Welding line profile.Welding form factor idiki zvakanyanya, weld chimiro chakamanikana uye chakadzika, gasi uye kusanganisa hakusi nyore kubuda uye nyore kugadzira pores uye slag.General weld factor control mu1.3-1.5, gobvu-yakavezwa pombi inosarudza iyo yakanyanya kukosha, uye hushoma kukosha kwehutete-madziro.

6 Kuderedza yechipiri magnetic field.Kuti uderedze zvinokonzeresa magineti kuvhuvhuta, iyo yekubatanidza chinzvimbo pane workpiece inofanira kugara kure neiyo terminal chikamu chewelding tambo kudzivirira yechipiri magineti inogadzirwa muworkpiece.

7 Technology:Inofanirwa kudzikisa kukurumidza kwewelding kana kuwedzera ikozvino, nekudaro kunonoka crystallization rate ye weld metal bath, kuitira kuti zvive nyore kusunungura gasi, asi kana nzvimbo yekuendesa isina kugadzikana, tambo inofanira kugadziriswa nenguva kuti ibvise. ekisesi yekumberi kuburikidza nekucheka kazhinji kana Bhiriji rakachengetwa richiumbwa, zvichiita kuti gasi ribude zvakaoma.
