Nzira dzekusiyanisa pombi dzesimbi dzakasungwa kubva papombi dzesimbi dzisina musono.

1. Metallography

Metallography ndiyo imwe yenzira huru dzekusiyanisa mapaipi esimbi ane welded kubvamapaipi esimbi asina musono. Yakakwirira-frequency kuramba welded simbi mapaipi haawedzere welding zvinhu, saka weld musono mu welded simbi pombi yakamanikana. Kana iyo nzira yekukuya yakaoma uye ipapo corrosion inoshandiswa, weld seam haigone kuonekwa zvakajeka. Kana iyo yakakwira-frequency kuramba yakakwenenzverwa simbi pombi yakasungwa uye isati yaitwa kupisa kurapwa, iyo weld chimiro ichave yakasiyana zvakanyanya kubva kune mubereki zvinhu zvepombi yesimbi. Panguva ino, iyo metallographic nzira inogona kushandiswa kusiyanisa welded simbi mapaipi kubva musono simbi pombi. Muchiito chekusiyanisa mapaipi maviri esimbi, zvakakosha kucheka sampuli diki nehurefu uye hupamhi hwe40mm panzvimbo yewelding, kuita kukuya kwakakasharara, kugaya kwakanaka uye kupukuta, uye wozoona chimiro pasi pemetallographic microscope. Kana ferrite uye widmanstatten, zvinhu zvevabereki uye weld zone dhizaini zvichionekwa, iyo welded simbi pombi uye musono pombi yesimbi inogona kunyatsosiyaniswa.

2. Corrosion nzira

Mukuita kwekushandisa nzira yekuora kusiyanisa pombi dzesimbi dzakasungwa uye pombi dzesimbi dzisina musono, weld yepombi yesimbi yakashongedzwa inofanirwa kukwenenzverwa. Mushure mekunge kupenya kwapera, zviratidzo zvekupenya zvinofanira kuonekwa. Zvadaro, chiso chekupedzisira chinoputirwa nejecha paweld, uye chiso chekupedzisira chinobatwa ne 5% nitric acid alcohol solution. Kana weld iri pachena ichionekwa, zvinogona kuratidzwa kuti pombi yesimbi ipipi yesimbi yakashongedzwa. Iko hakuna mutsauko wakajeka mumagumo kumeso kwepombi yesimbi isina musono mushure mekuora.

3. Kusiyanisa mapaipi esimbi akasungwa uye mapaipi esimbi asina musono maererano nemaitiro

Mukuita kusiyanisawelded simbi pombiuye mapombi esimbi asina musono maererano nemaitiro, ese akasungwa simbi pombi anoiswa welded zvinoenderana nemaitiro akadai sekutonhora kukunguruka uye extrusion. Uye zvakare, kana yakakwira-frequency, yakaderera-frequency arc welding pombi uye kuramba welding pombi dzinoshandiswa kubatanidza pombi dzesimbi, spiral pombi welding uye yakatwasuka musono pombi welding ichaumbwa, iyo inoumba mapaipi esimbi akatenderera, sikweya simbi pombi, oval simbi. mapaipi, mapaipi esimbi ane mativi matatu, mapaipi esimbi ane hexagonal, pombi dzesimbi dzakasvava, pombi dzesimbi dzine makona, uye kunyange pombi dzesimbi dzakaoma kunzwisisa. Muchidimbu, maitiro akasiyana anozogadzira mapaipi esimbi emhando dzakasiyana, kuitira kuti mapaipi esimbi akasungwa uye mapaipi esimbi asina musono anogona kunyatsosiyaniswa. Nekudaro, mukuita kusiyanisa pombi dzesimbi dzisina musono zvichienderana nemaitiro, dzinonyanya kusiyaniswa zvichienderana nekupisa kukungurukwa uye kutonhora kukungurutswa nzira dzekurapa, uye isina musono pombi dzine mafomu maviri makuru, anoti inopisa-yakakungurutswa seamless simbi pombi uye inotonhora- pombi dzesimbi dzisina musono. Mapaipi esimbi anopisa-akakungurutswa asina musono anoumbwa nekuboora, kukunguruka uye mamwe maitiro, kunyanya mahombe-dhayamita uye akakora musono pombi dzesimbi dzakasungwa nemaitiro aya; mapaipi anotonhorera anoumbwa nekudhirowa kunotonhora kwepombi, uye kusimba kwechinhu chacho kwakadzikira, asi nzvimbo dzayo dzekunze nedzemukati dzakatsetseka.
