In high-frequency longitudinally welded pombi(ERW simbi pombi), kuratidzwa kwekutsemuka kunosanganisira kutsemuka kwenguva refu, kutsemuka kwepanguva nenguva kwenzvimbo uye kutsemuka kusingaite kwepakati. Kunewo mamwe mapaipi esimbi asina kuputika pamusoro pepamusoro mushure mekugadzira, asi makatsemuka anozoonekwa mushure mekubata kumeso, kutwasanudza kana kuyedzwa kwemvura.

Zvikonzero zvekutsemuka

1. Hunhu husina kunaka hwezvigadzirwa

Mukugadzirwa kwepombi dzakasungirirwa, kazhinji kune mabhura akakura uye akawandisa mbishi hupamhi hwematambudziko.
Kana iyo burr iri kunze panguva yekugadzira welding, zviri nyore kugadzira inoenderera uye yakareba inopindirana yakatsemuka.
Upamhi hwezvinhu zvakasvibirira zvakakura zvakanyanya, gomba rekusvina rakazadzwa-rakazadzwa, richigadzira chimiro chepeach welded, macherechedzo ekunze akakura, welding yemukati idiki kana kwete, uye inotsemuka mushure mekutwasanuka.

2. Edge kona yakabatana mamiriro

Iyo kona yekubatanidza mamiriro ekumucheto kwechubhu isina chinhu chinhu chinowanzoitika mukugadzirwa kwewelded tubes. Iyo diki iyo dhayamita yepombi, iyo yakanyanya kuoma yekona yejoint.
Kusakwana kwekugadzirisa kugadzirisa chinhu chinodiwa kune majoini emakona.
Iyo isina kukodzera dhizaini ye squeeze roller pass, iyo yakakura yekunze fillet uye yakakwira angle yekumanikidza roller ndizvo zvakakosha zvinokanganisa angle joint.
Single radius haigone kubvisa matambudziko epakona anokonzerwa nekuumbwa kwakashata. Wedzera simba rekudzvanya, zvikasadaro iyo yekusvina roller inopera uye ikaita elliptical mune yekupedzisira nhanho yekugadzira, izvo zvinozowedzera kupinza kwakapinza kwepeach-shape welding state uye kukonzeresa kubatanidza kwekona.

Kubatana kwekona kuchaita kuti simbi yakawanda ibude kubva kumusoro, ichigadzira kusagadzikana kwekunyunguduka. Panguva ino, pachange paine yakawanda yesimbi inoputika, iyo welding seam ichave yakanyanyisa kupisa, uye ekunze burrs ichave inopisa, isina kujairika, yakakura uye isiri nyore kukwenya. Kana iyo welding yekumhanyisa ikasadzorwa zvakanaka, "kunyepedzera welding" yeweld inozoitika.

Iko kunze kwekona ye squeeze roller yakakura, kuitira kuti chubhu isina kuvharwa isati yazara mukusvina roller, uye kumucheto kwekubatana kwenyika kunoshanduka kubva pakufanana kusvika ku "V" chimiro, uye chiitiko chokuti mukati welding welding seam haina kuputika. .

Iyo yekusvina roller inopfekwa kwenguva yakareba, uye base bearing rakapfekwa. Iwo mashaft maviri anoumba kona yekukwirira, zvichikonzera kusakwana kwesimba rekudzvanya, vertical ellipse uye yakanyanya angle kubatikana.

3. Kusanzwisisika kusarudzwa kwemaitiro ekugadzirisa

Iyo maitiro parameters epamusoro-frequency welded pombi kugadzirwa anosanganisira welding kumhanya (unit kumhanya), welding tembiricha (yakakwirira-frequency simba), welding ikozvino (yakakwirira-frequency frequency), extrusion simba (kukuya chishandiso dhizaini uye zvinhu), kuvhura kona (kukuya. ) yedhizaini Dhizaini uye zvinhu, chinzvimbo cheiyo induction coil), inductor (chinyorwa checoil, inotenderedza nzira, chinzvimbo) uye saizi uye chinzvimbo chekuramba.

(1) High frequency (yakadzikama uye inoenderera) simba, welding kumhanya, welding extrusion simba uye yekuvhura angle ndiyo inonyanya kukosha maitiro paramita, izvo zvinofanirwa kufananidzwa zvine musoro, zvikasadaro kunaka kwewelding kuchakanganiswa.

①Kana kumhanya kwakanyanyisa kana kuderera, zvinokonzeresa kudzika-tembiricha welding kusamira uye kupisa-kupisa kwakanyanya, uye weld inotsemuka mushure mekubatika.

②Apo simba rekusvina harina kukwana, simbi yemucheto inosungirirwa haigoni kusungirirwa pamwe chete, tsvina yakasara mu weld haisi nyore, uye simba rinoderedzwa.

Kana iyo extrusion simba yakawandisa, iyo simbi inoyerera angle inowedzera, iyo yakasara inoburitswa nyore, iyo inopisa-inokanganiswa nzvimbo inova nhete, uye welding mhando inovandudzwa. Zvisinei, kana dzvinyiriro yakanyanyisa, inokonzera sparks makuru uye splashes, zvichiita kuti oxide yakanyungudutswa uye chikamu chesimbi yepurasitiki ibudiswe, uye weld inova yakatetepa mushure mokukwenya, nokudaro kuderedza simba re weld.
Yakakodzera extrusion simba chinhu chakakosha chinodiwa kuti uve nechokwadi chewelding mhando.

③Iyo kona yekuvhura yakakurisa, iyo inoderedza yakakwira-frequency kuswedera, inowedzera kurasikirwa kwazvino eddy, uye inoderedza tembiricha yewelding. Kana welding pakumhanya kwepakutanga, makatsemuka achaonekwa;

Kana kona yekuvhura iri diki, iyo welding ikozvino ichave isina kugadzikana, uye kuputika kudiki (intuitively a discharge phenomenon) uye kuputika kuchaitika pakusvina.

(2) Iyo inductor (coil) ndiyo chikamu chikuru chewelding chikamu chepamusoro-frequency welded pombi. Mukaha uripo pakati payo uye chubhu isina chinhu uye hupamhi hwekuvhura ine simba guru pamhando yewelding.

① Mukaha pakati peinductor uye chubhu isina chinhu yakakura zvakanyanya, zvichikonzera kudonha kwakapinza kweinductor kunyatsoita;
Kana mukaha uripo pakati peinductor uye chubhu isina chinhu iri diki, zviri nyore kugadzira kubuda kwemagetsi pakati peinductor nechubhu isina chinhu, zvichikonzera kuparuka kwewelding, uye zvakare zviri nyore kukuvara nechubhu isina chinhu.

② Kana hupamhi hwekuvhura hweinductor hwakanyanya, huchadzikisa tembiricha yewelding yemupendero webutt wechubhu isina chinhu. Kana iyo yekumhanyisa kumhanya ichikurumidza, manyepo ekunyepa uye makatsemuka zvinogona kuitika mushure mekutwasanuka.

Mukugadzirwa kwe-high-frequency welded pipes, pane zvinhu zvakawanda zvinokonzera weld cracks, uye nzira dzekudzivirira dzinosiyanawo. Kune akawanda akasiyana-siyana mu-high-frequency welding process, uye chero kukanganisa kwekubatanidza kunozopedzisira kwakanganisa kunaka kwewelding.
