1. Yakasiyana yeganda mavara uye ruvara, welding makwapa
Chikonzero 1 : Nyaya yenzvimbo yewelding yakasiyana neyokutanga zvinhu.
Matanho anoenderana: Shandisa waya yekukweshesa inoenderana nehwaro zvinhu, zviri nani waya wakakosha welding unoshandiswa muzvigayo zvesimbi; chechipiri, akaona zvinhu kubva pahwaro zvinhu; kana kushandisa universal welding wire.
Chikonzero 2 : Kupisa kwekupisa kwenzvimbo yewelding kwakasiyana neiyo yenzvimbo yepakutanga, uye chimiro chinoshanduka.
Zviyero zvinoenderana: Kupisa kurapwa kunoitwa mushure mekuputika kuita kuti chimiro chezviyo chienderane; zvikamu zvakakosha zvinonyatsoshanda zvinoenderana nesimbi yechirimwa welding process.
2. Kutsemuka uye deformation
Chikonzero: Kana zvikamu zvakaiswa pasi peargon arc welding, zvinopisa munzvimbo, zvichiita kuti kutonhora kwakasiyana-siyana munzvimbo dzakasiyana dzezvikamu uye kuunza kupisa kwemukati kunetseka; mushure mekuputika, nzvimbo yakatarisana nenzvimbo yewelding inonyatso kudzima, uye nzvimbo iyi yakaoma zvikuru uye inowanzoputika.
Cherechedza:
1. Iyo yakakura nzvimbo yewelding, iyo yakanyanya kushushikana kwemukati inogadzirwa.
2 Iyo yakakwirira iyo kabhoni uye alloying element zvirimo, zvinotonyanya kuwedzera weldability. Kana ichidarika 0.4%, preheating uye post-heating inodiwa.
3. Iyo yakakwirira kuoma kwechikamu, iyo yakakura yepakutanga kushushikana kwemukati uye zviri nyore kutsemuka.
4. Iyo inopinza chimiro, zviri nyore kuti chikamu chitsemuke.
Matanho anoenderana: Preheat yese uye ita kupisa mushure mekupisa.
Cherechedza:
Nokuda kwekuisa kukuru, kuitira kuti udzivise kushushikana kunokonzerwa nekupisa (kunyange kana chikamu chose chichipisa, kutonhora kwechikamu kunobva kunze kusvika mukati, izvo zvinogona kuramba zvichikonzera kushushikana kwemukati) , Paunenge uchipisa, ramba uchidziya pakupisa kwepakati kwechinguva usati wapisa zvakare.
3. Makomba ejecha uye pores
Chikonzero 1: Welder tekinoroji matambudziko, mapundu mukuunganidza weld point.
Zvinoenderana matanho: Shandisa welding tsvimbo zvakanyanya sezvinobvira; Chenjerera uye chenjera paunenge uchiturika.
Chikonzero 2 : Kana ma part ane nitrided akasungwa, mamorekuru enitrogen anonyungudika oita pores nekuda kwekudziya.
Zvinoenderana matanho: welding pamberi nitriding; Gaya pasi nitride layer.
Chikonzero chechitatu : Pane kusvibiswa pamusoro welding surface uye tsvimbo yekugadzira haina kuomeswa sezvinodiwa, zvichiita kuti gasi rive chizvarwa panguva yekunyunguduka.
Zviyero zvinoenderana: Pamberi pekuputira, girisi, kupfeka, kugadzira lubricant uye oxide firimu pamusoro peiyo weldment inofanira kubviswa; matanda emoto anofanira kuomeswa sezvinodiwa.
4. Kuderedza kuoma uye annealing yemunharaunda
Chikonzero: Shanduko yekushisa panguva yekushongedza inokonzera kupisa kupisa pazvikamu, zvichikonzera kuchinja kwezvinhu zvezvikamu.
Matanho anoenderana: Tevedzera nzira yewelding inopihwa nemupi wesimbi.
5. Mamwe Mazano
Ruzivo rwekutanga rwesimbi kupisa kurapwa: 1. Kana simbi ichiiswa pakupisa kupisa senge nitriding kana general preheating welding, chenjerera kuti tembiricha haifanire kudarika tembiricha yekupisa yesimbi isati yabva mufekitori, kana zvisina kudaro kuoma kwesimbi kuchaderedzwa uye deformation yezvikamu zvichakonzerwa.
P20 yakazara preheating inokurudzirwa yakajairika kupisa kurapwa maitiro: preheat kusvika 350-450 madhigirii uye wozopisa, kushatirwa kwakatenderedza 550 madhigirii (yekuputira akakosha mould, maitiro ekupisa kupisa anofanirwa kudzorwa zvakanyanya maererano nekurudziro yemugadziri).
Kuti udzivise makomba ejecha akadzokororwa panguva yekukwenenzverwa mushure mekutsvaira, welding flaw detector inogona kushandiswa kutarisa kutanga mushure mekugadzira. Nzvimbo dzine dambudziko dzinogona kucherwa dzozoiswa weld kuitira kudzivirira makomba ejecha anodzokororwa.
Welding ye beryllium mhangura: Beryllium mhangura inonyanya kubatwa neoxidation. Inofanira kunge yakasungirirwa pakarepo mushure mokunge firimu reoxide rabviswa nebhurashi rinopinza kana sandblasting. Kuoma kwenzvimbo yakashongedzwa uye nzvimbo dzayo dzakapoteredza dzichaderera. Kana kuomarara kuderera kusingagamuchirwi, kurapazve kupisa kunodiwa.
