Welding zvimiro zvemhando dzakasiyana dzemhangura alloys

Welding zvinhu zvakasiyana-siyanaalloys emhangura:

1. Thermal conductivity yemhangura tsvuku yakakwirira.Iyo yekupisa conductivity yemhangura tsvuku pane tembiricha yekamuri inenge kasere yakakura kupfuura iyo yekabhoni simbi.Zvakaoma kudziya munzvimbo yemhangura weldment kune tembiricha yekunyungudika.Naizvozvo, chitubu chekupisa chine simba rakawanda chinofanira kushandiswa panguva yewelding.Kutsemuka kunowanzoitika apo mhangura nemhangura alloys zvakasungwa.Kutsemuka kunowanikwa mune welds, fusion mitsetse uye nzvimbo dzakakanganiswa nekupisa.Iyo yakatsemuka ndeye intergranular kukuvara, uye pachena oxidation ruvara runogona kuoneka kubva pamuchinjikwa chikamu.Munguva yewelding crystallization process, tsvaga okisijeni nemhangura fomu Cu2O, uye gadzira yakaderera-yakanyunguduka eutectic (α+Cu2O) ine α mhangura, uye nzvimbo yekunyungudika i1064 ° C.

2. Mutobvu haunyungudike mumhangura yakasimba, uye mutobvu nemhangura zvinoumba eutectic inonyungudika yakaderera ine nzvimbo yekunyungudika inosvika 326°C.Pasi pechiito chekusimudzira kushushikana kwemukati, mhangura nemhangura alloy majoini pakupisa kwakanyanya kuumba kuputika muzvikamu zvisina kusimba zvemajoini akasungwa.Mukuwedzera, hydrogen mu weld inogona kukonzera kutsemuka.Porosity inowanzoitika mune welds yemhangura nemhangura alloys.Porosity mu pure copper weld metal inonyanya kukonzerwa nehydrogen gasi.Kana CO gasi inonyungudutswa mumhangura yakachena, pores inogona zvakare kukonzerwa nemhute yemvura uye CO2 gasi inogadzirwa nekuita kwekabhoni monoxide uye oksijeni.

3. Iyo porosity yekugadzira maitiro emhangura alloy welding yakakura zvikuru kupfuura yemhangura yakachena.Kazhinji, ma pores akagoverwa pakati pe weld uye padyo nemutsara wekusanganisa.Kana mhangura yakachena nemhangura alloys yakashongedzwa, iyo mechanical properties yejoint inowanzodzikira.Mune welding process yemhangura alloys, mhangura oxidation, uye evaporation uye kupisa kwezvinhu zvealloy zvichaitika.Iyo yakaderera melting point eutectic uye kwakasiyana-siyana welding defects inotungamira mukudzikiswa kwesimba, plasticity, corrosion resistance uye magetsi conductivity yejoint welded.
