Ntau tus neeg muas zaub yuav nug, koj puas tuaj yeem ua txhuas phaj? Thaum welding aluminium yog ntsib feem ntau hauv kev ua, qhov tseeb, aluminium vuam tsuas yog nyob ntawm cov khoom siv. Feem ntau cov ntawv txhuas, txhuas daim hlau, txhuas daim hlau, thiab lwm yam Peb yuav tsum xyuam xim rau dab tsi thaum vuam? Cia peb saib:
1. Siv vuam hlau rau txhuas phaj vuam
Thaum welding ntshiab txhuas daim hlau (1060 txhuas daim hlau), purity ntawm cov hlau feem ntau tsis qis dua lub hauv paus hlau.
Thaum cov nplooj ntawv aluminium alloy yog welded, cov tshuaj muaj pes tsawg leeg ntawm cov hlau feem ntau cuam tshuam los yog ze rau lub hauv paus hlau.
Thaum welding aluminium alloy daim hlau, cov ntsiab lus corrosion-resistant (magnesium, manganese, silicon, thiab lwm yam) nyob rau hauv cov hlau feem ntau tsis qis dua lub hauv paus hlau.
2. Xaiv txoj kev vuam ntawm txhuas phaj
Castings thiab vuam zoo yuav tsum tau rau welding ntawm txhuas daim hlau tsis zoo thiab feem ntau yog siv rau cov roj welding.
Vuam electrode arc vuam siv tau los kho aluminium alloy castings.
Inert gas welding (TIG lossis MIG) yog txoj kev siv dav tshaj plaws rau vuam txhuas thiab txhuas alloys.
Pure aluminium thiab aluminium alloy daim hlau tuaj yeem siv rau tungsten arc vuam lossis tungsten pulse argon arc vuam.
Pure aluminium thiab aluminium alloy tuab daim hlau tuaj yeem siv rau tungsten arc vuam, argon-helium sib xyaw tungsten arc vuam, arc arc vuam thiab mem tes arc arc vuam. (Argon lossis Argon / Helium) Gas Shielded Vuam thiab Pulse Melting Electrode Gas Shielded Vuam (Argon thiab Argon / Helium Mixed Gases)
Ntawm chav kawm, thaum vuam, ntxuav thiab ua haujlwm tu yuav tsum tau ua ua ntej vuam. Ntev npaum li txoj kev vuam yog qhov tseeb, cov kab nrib pleb yuav tsis tshwm sim tom qab vuam aluminium.
