Welded Pipe Process

Magetsi Resistance Welding Process (ERW)

Pipe yeSimbi Muchigadziro chekusimudzira, mapaipi anogadzirwa nekupisa, uye kutonhora kuumbwa kwepepa resimbi yakatsetseka mune cylindrical geometry. Magetsi emagetsi anobva apfuura nemumicheto yesimbi silinda yekupisa simbi uye kugadzira chisungo pakati pemicheto kusvika painomanikidzwa kusangana. Munguva yeREG maitiro, zvinhu zvekuzadza zvinogona kushandiswa zvakare. Kune marudzi maviri ekupikisa welding: high-frequency welding uye inotenderera yekubata vhiri welding.

Chinodiwa chepamusoro-frequency welding chinobva pamaitiro ezvigadzirwa zvakadzika-frequency welded kuti zvisarudze kuparara kwemajoini, kuputika kwehokwe, uye kusakwana kwemajoint bonding. Nokudaro, zvisaririra zvinoputika zvehondo yepasi-frequency haachashandiswa kugadzira mapaipi. Iyo yakakwira-frequency ERW process ichiri kushandiswa mukugadzira chubhu. Kune marudzi maviri epamusoro-frequency REG maitiro. High-frequency induction welding uye high-frequency contact welding imhando dzepamusoro-frequency welding. Mune yakakwira-frequency induction welding, iyo welding ikozvino inotumirwa kune iyo zvinhu kuburikidza nekoiri. Iyo coil haisangani nepombi. Magetsi azvino anogadzirwa muchubhu zvinhu neiyo magineti yakatenderedza chubhu. Mu-high-frequency contact welding, magetsi emagetsi anotumirwa kune zvinyorwa kuburikidza nevanosangana pamucheka. Welding simba rinoshandiswa zvakananga kune pombi, zvichiita kuti nzira yacho ibudirire. Iyi nzira inowanzosarudzwa pakugadzira mapaipi ane madhayamita makuru uye kukwirira kwemadziro.

Imwe mhando yekupikisa welding ndiyo inotenderera yekubata vhiri welding process. Munguva iyi, magetsi emagetsi anofambiswa kuburikidza nevhiri rekubatanidza kusvika kune welding point. Gumbo rekusangana rinogadzirawo kudzvanywa kunodiwa pawelding. Rotary contact welding inowanzo shandiswa kune zvikumbiro zvisingakwanise kugadzirisa zvipingamupinyi mukati mepombi.

Magetsi Fusion Welding process (EFW)

Iyo yemagetsi fusion welding process inoreva maerekitironi beam welding yendiro yesimbi uchishandisa kumhanyisa-kumhanya kweyerekitironi danda. Iyo yakasimba simba kinetic simba remagetsi erekitironi rinoshandurwa kuita kupisa kupisa workpiece kugadzira weld seam. Iyo weld nzvimbo inogona zvakare kupisa kupisa kuita kuti weld isaonekwe. Mapombi akaiswa simbi anowanzo kuve neakasimba dimensional kushivirira kupfuura mapaipi asina musono uye, kana akagadzirwa muhuwandu hwakafanana, anodhura zvishoma. Inonyanya kushandiswa kugadzira mahwendefa esimbi akasiyana-siyana kana simba guru remagetsi, simbi yakasungirirwa zvikamu zvinogona kukurumidza kupisa kusvika kune tembiricha yakakwira, ichinyungudusa simbi dzese dzinoramba uye alloys.

Submerged Arc Welding process (SAW)

Kunyudzwa kwearc welding kunosanganisira kugadzira arc pakati pewaya electrode uye workpiece. Rukova runoshandiswa kugadzira gasi rekudzivirira uye slag. Sezvo iyo arc inofamba ichitevedza musono, kuyerera kwakanyanya kunobviswa kuburikidza nefunnel. Nekuti iyo arc yakafukidzwa zvachose neiyo flux layer, kazhinji haionekwe panguva yewelding, uye kurasikirwa kwekupisa zvakare kwakadzikira zvakanyanya. Kune marudzi maviri eakanyura arc welding process: vertical undermerged arc welding process uye spiral yakanyura arc welding process.

Mune longitudinal yakanyudzwa arc welding, kureba mipendero yemarata esimbi inotanga kubhedhenurwa nekugaya kuti iite chimiro cheU. Mipendero yemapureti akaita U-anobva asungwa. Mapombi anogadzirwa neichi maitiro anoiswa pasi pekuwedzera mashandiro kuitira kudzoreredza kushushikana kwemukati uye kuwana yakakwana dimensional kushivirira.

Mu spiral undermerged arc welding, weld seams akafanana nehelix yakatenderedza pombi. Mune ese ari maviri ehurefu uye spiral welding nzira tekinoroji imwe chete inoshandiswa, mutsauko chete ndeye spiral chimiro chemisono mu spiral welding. Maitiro ekugadzira ndeyekukungurusa simbi tambo kuitira kuti inotenderedza nzira iite kona ine radial kutungamira kwechubhu, chimiro, uye weld kuitira kuti weld mutsara urare mukutenderera. Iyo inonyanya kuipa yeiyi nzira ndeye hurombo hwemuviri huyero hwepombi uye yakakwirira majoini kureba izvo zvinogona kutungamirira nyore kuumbwa kwekuremara kana kuputika.
