Muzvinyorwa zvekupedzisira, takakurukura zvikamu zvezvikonzero uye zviyero zvekudzivirira zvesimbi zvakasikwa zvisina kuremara pombi. Nhasi, tinoramba tichinyanyisa kufukura vamwe vese.
6. Crater
Chikamu chezuva pakupera kweWel of the weld yeiyo isina tsvina yelted yelded yePipe inonzi iyo arc crater. Iyo arc crater isinganyanye kushungurudza zvakanyanya simba remubenzi ipapo, asi zvakare anogadzira arc cratter cratter nekuda kwekusangana kwekusvibiswa.
Zvinokonzera: Chikonzero chikuru ndechekuti nguva yekugara yeARC ipfupi. Izvo zviripo zvakakura kwazvo kana takatetepa mahwendefa.
Matanho ekudzivirira: apo electrode arc Welding yakavharwa, iyo electrode inofanirwa kugara mudziva rakanyungudutswa kwechinguva kana kumhanya mune imwe kutenderera, uye ndokuenda kune rumwe rutivi rwekudzima iyo arc mushure mekudzima iyo del. Tungsten Argon Arc Tulting, panofanira kunge nekukwana nguva yekugara inochengeterwa uye arc inodzimwa mushure mekunge Wel.
7. Stomata
Paunotarisa svutugadzike simbi yakasviba yakavezwa. Porosity izere nehuremu hwakajairika, iyo inogona kukamurwa kuva porosity yemukati uye porosation yekunze muWeld. Stomata inotenderera, oiri, zvipembenene-yakaumbwa, yakaomeswa-yakaumbwa uye dense. Kuvapo kwemapombi hakuzoite kungoita kukosha kweiyo weld, asi zvakare kuderedza nzvimbo inoshanda yeiyo weld uye kuderedza michina yemuchina weiyo weld.
Inokonzera: Kune mafuta, ngura, kunyorova uye imwe tsvina iri pamusoro uye groove yeiyo hutsinye simbi yakasviba yechipomba Iyo yekuvhara yeiyo Electrode yakanyura panguva yeArC Tulting uye haina kuomeswa usati washandiswa; Iyo arc yakanyanya kureba kana kusarura ichivhuvhuta, kudzivirirwa kwakanyungudika kwePoolt hakuna kunaka, mweya unopinda mudziva rakanyungudutswa; Yakatwasira iripo yakanyanya, iyo electrode inova tsvuku, iyo coating inowira pasi mangwanani, uye maitiro ekudzivirira arasika; Iyo yekuvhiya nzira haina kunaka, sekuvhiringidza arc yekuvhara zvakanyanya, zviri nyore kuburitsa shiri, uye arc inoshamisa chiitiko chejoini haina kunaka, iri nyore kuburitsa desere stomata, nezvimwe.
Matanho ekudzivirira: usati wasvitsa, bvisa mafuta, ngura, uye unyoro mukati megore Bika nenzira yakasarudzika ne tembiricha uye nguva yakatarwa muElectrode bhuku; Sarudza nenzira kwayo Welding proceter emahara uye inoshanda nemazvo; Shandisa pfupi arc zvakanyanya sezvinobvira zvinobvira, kuvakwa kwemunda kunofanirwa kuve nezvivakwa zvemhepo zvemhepo; Electrodes isiriyo haitenderwe, sekuti seyekufambisa core Core Corrosion, kuunganidza kupaza, kutarisana, kunyanyisa kweccentricity, nezvimwe.
8. Zvinangwa uye kusagadzikana kwekuda
Kufambiswa kwacho kusiri-simbi kusanganisa uye nzombe inosara muWeld simbi inogadzirwa nemitolluriki maitiro. Silg inclusions dzakanyungudutswa dzinoramba dzasara muWel. Simbi isingabatsiri yePIPE SLAG ALCLUSIONS inogona kukamurwa kuita marudzi maviri: Spot slag inclusions uye strip slag castlusions. Iyo SLAG Kubatanidzwa Kunosimbisa Chikamu Chinobudirira cheWelk, nokudaro kuderedza michero yemakwenzi yeWeld. SlAg inclusions inogona zvakare kukonzera kushushikana kushushikana, iyo inogona kukuvadza nyore nyore chimiro chakarukwa kana chakatakurwa. Zvinokonzera: Iyo Interlayer slag haina kuchena panguva yekuita nzira; iyo nongororo iripo idiki kwazvo; kumhanya kwekumhanya kwakanyanya kwazvo; Iko kuvhiya kwacho kwakashata panguva yekuita mafambiro; Kuumbwa kwemakemikari ezvinyorwa zvekutengesa uye simbi yekutsika haina kunyatsoenderana;
Matanho ekudzivirira: Sarudza electrodes neakanaka slag kubvisa kuderedzwa kwekuita; nyatso bvisa inopindira pasi; zvine musoro sarudza tulating proceter ma parameter; gadzirisa electrode angle uye nzira yekufambisa.
Kana uchisarudza a Welded Pipe Production Line , iwe unogona kufunga nekuisa iyo yakangwara plc system. Hangocha Tech (Seko Machinery) Plc system haigone kutarisa data rekugadzira munguva chaiyo, asi zvakare kuti maitiro ekugadzira anogona kuwana zvinyorwa zveDatabase chero nguva.
9. Pisa kuburikidza
Munguva yeTalding maitiro, simbi yakanyungudutswa inoyerera kubva kumashure kweiyo groove, uye kuremara kwekutsamwa kweiyo pombi yetsvina yakacheneswa. Burn-kuburikidza neimwe yeiyo yakajairika kuremara muArc tulating.
Inokonzera: Yakakura Welding yazvino, inononoka kumhanyisa kumhanya, kupisa kwepombi yemhete; yakakura groove gakiti, yakaonda kwazvo grunt centra; murombo welder mashandiro ekushandisa, nezvimwe.
Matanho ekudzivirira: Sarudza yakakodzera testing proceteres uye yakakodzera groove size; Kuvandudza hunyanzvi hweWelder's Ekushanda, nezvimwe.

Makanda ehutsanana simbi isina kuchengetwa mapepa anokonzerwa nemarara anotonhora, marara anopisa uye tsandanywa makatsemuka maererano nekudziya uye nenguva dzinoitika; Vanogona kukamurwa muLongitudinal cracks, transverse marara, weld marara marara, etsion crater
(1) kupenga kunopisa
Munguva yekuita, iyo makatambudza inogadzirwa neSeam uye simbi munzvimbo inopisa-yakakanganisika inotonhora kune yakakwira tembiricha padhuze nemutsara weSimba. Icho chine njodzi ine njodzi iyo isingatenderwi kuvapo. Sekureva kwemuchina, tembiricha yemapipi uye chimiro chePIPE PIPE BRACKS, mapundu anokonzerwa nemachira, akakwira tyqueficistaction
Chikonzero: Chikonzero chikuru ndechekuti iyo yakadzika yekunyungudika poutectic uye kusvibiswa mune yakanyungudika simbi fomu yakakomba intragranault Pamwe chete miganhu yezviyo inodhonzwa kunze, inogadzira marara anopisa. Mbira dzinopisa dzinowanzoitika muAustenitic Stainless Simbi, Nickel Alloy uye Aluminium Alloy. Low-carbon simbi kazhinji haisi nyore kuburitsa mitsara inopisa panguva yeWelding, asi sezvo iyo kabhoni yezvinyorwa zvesimbi inowedzera, tsika yekupisa kupaza inowedzera. Zviyero Zvekudzivirira: Zvakanyatso kudzora zvirimo zvechisimba zvinokuvadza senge sulfurus uye phosphorous mune simbi yesimbi yakamonera uye kuderedza mafungiro emarara anopisa; Gadzirisa mamiriro emakemikari emasimbi emvura, achivandudza chimiro cheWeld, anatsikisa zviyo, achivandudza kupararira, kuderedza kana kuparadzira mwero wekusaririra; Shandisa alkaline welking midziyo yekudzikisa zvirimo zvekusvibiswa mune weld uye kugadzirisa huwandu hwekusaririra; Sarudza yakakodzera Welding proceters Shandisa iyo denderedzwa rakafanana-kunze simbi simbi, kana zvishoma nezvishoma kudzima arc, uye kuzadza iyo arc crater kuti udzivise kupaza marangi eArc.
(2) inotonhora marara
Iwo mabundu akagadzirwa apo iyo yakavezwa yakabatanidzwa kune imwe tembiricha yekudziya (yesimbi pazasi M. Tembiricha) inodaidzwa kutonhora marara. Cold cracks inogona kuoneka pakarepo mushure mekutora, kana inogona kutora nguva yenguva (maawa, mazuva kana kunyange kureba) kuoneka. Rudzi urwu rwekupaza runonziwo runononoka. Njodzi huru.
Inokonzera
Matanho ekudzivirira: Sarudza yakaderera-hydrogen Walding zvinhu, uye muvabate mukuwirirana nemirairo isati yashandiswa; Bvisa mafuta uye unyoro pane maWalkments usati wabereka, uye kuderedza iyo hydrogen yezvinyorwa muWeld; Sarudza Inonzwisisika Welding procetes uye kupisa yekuisa kuti uderedze kuomarara kwakaoma kweSEAM SEAM; Iyo hydrogen yekubvisa kurapa kunoitwa nekukurumidza mushure mekutora kuti hydrogen ichitiza kubva kujoina yakavanzika; Kune iyo simbi yesimbi yakacheneswa isina kuomarara, ichipfuudza isati yasvika uye yekupfura kurapwa munguva mushure mekutora mari inogona kuvandudza chimiro uye kunaka kwejoini. Kuita; Kuora matanho akasiyana siyana ehunyanzvi kuderedza kushushikana.
(3) REHEAT MAHARA
Mushure mekutyaira, iyo simbi yesimbi yakasviba inodzorwa mukati meimwe tembiricha yekudziya (kusimbisa kwekunyepedzera kupisa kana kumwe kuronga) uye mabundu anonzi renhema.
Zvinokonzera Mushure mekutenderera kwekutenderera kwemvura, ivo vanoiswa kunzvimbo inonzwisisika (550 ~ 650 ℃). Mazhinji emakonzo anobva munzvimbo ine coarse-yakagadzirirwa yeiyo yekupisa kupisa-inokanganiswa nzvimbo. Zvizhinji zveRehat marobhoti anoitika mune simbi yesimbi yakachengetwa uye kusagadzikana nzvimbo dzekusimbisa, uye rehetera cracks dzimwe nguva zvichiitika mune akawanda-layer welding.
Matanho ekudzivirira: Pane zvivakwa zvekusangana zvinodikanwa zvegadziriro, sarudza zvakaderera-simba zvekushandisa zvakaderera pane izvo zvesimbi pasi, uye kushushikana kwakazorora muWels kuti udzivise marara munzvimbo inopisa; kuderedza kushushikana kwakasara nguva uye kushushikana kushushikana; Dzora iyo Inosimbisa Kupisa Pombi yePombi Yakatemwa, Inonzwisisika Sarudza iyo yekunyepedzera uye kupisa kurapa tembiricha, uye kudzivirira nzvimbo inonzwisisika zvakanyanya sezvinobvira.
