Aluminium welding hlau yog ib hom tshwj xeeb ntawm vuam consumable siv los koom nrog txhuas qhov chaw hauv tsheb thiab aerospace daim ntaub ntawv. Aluminium, paub txog nws lub teeb yuag thiab siab zog-rau-hnyav piv, yog cov khoom siv nrov siv hauv kev tsim tsheb thiab dav hlau vim nws cov khoom tsim nyog.
Thaum nws los txog rau vuam aluminium, nws tuaj yeem nyuaj vim nws cov thermal conductivity thiab qis melting point piv rau lwm yam hlau. Yog li ntawd, xaiv qhov zoo ntawm aluminium welding hlau yog qhov tseem ceeb los xyuas kom meej vuam kev ua tau zoo thiab zoo welds nyob rau hauv automotive thiab aerospace daim ntaub ntawv.
Nov yog qee yam tseem ceeb uas yuav tsum tau xav txog thaum xaiv aluminium vuam hlau rau kev siv tsheb thiab aerospace:
Alloy muaj pes tsawg leeg: Aluminium welding xov hlau muaj nyob rau hauv ntau yam alloy compositions, txhua tus muaj cov yam ntxwv thiab cov yam ntxwv. Feem ntau cov alloys siv nyob rau hauv tsheb thiab aerospace daim ntaub ntawv yog 5xxx thiab 6xxx series alloys, uas paub txog lawv zoo heev zog, corrosion kuj, thiab weldability. Lwm cov alloy series xws li 2xxx, 3xxx, thiab 7xxx kuj tseem siv tau rau hauv cov ntawv thov tshwj xeeb.
Hlau txoj kab uas hla: Txoj kab uas hla ntawm vuam hlau yog ib qho tseem ceeb rau kev txiav txim siab vim nws cuam tshuam rau cov cua sov nkag thaum lub vuam. Cov xov hlau Thicker xav tau cov vuam tam sim no dua, thaum cov xov hlau nyias nyias yuav xav tau qis dua. Qhov kev xaiv ntawm txoj kab uas hla yog nyob ntawm qhov tuab ntawm cov txhuas qhov chaw raug welded thiab cov txheej txheem vuam siv.
Hlau hom: Aluminium welding hlau muaj nyob rau hauv ntau hom, xws li cov xov hlau, flux-cored xov hlau, thiab hlau-cored xov hlau. Cov khoom siv hlau feem ntau yog siv rau cov roj hlau arc vuam (GMAW) lossis tungsten inert gas (TIG) vuam, thaum cov xov hlau flux-cored thiab hlau-cored yog siv rau cov txheej txheem vuam sib txawv xws li roj-shielded flux-cored arc vuam (FCAW). ) thiab pulsed gas hlau arc vuam (GMAW-P).
Shielding gas: shielding roj yog siv los tiv thaiv cov vuam ntawm atmospheric paug thaum vuam. Rau txhuas vuam, sib tov ntawm argon thiab helium los yog argon thiab hydrogen feem ntau yog siv los tiv thaiv roj. Qhov kev xaiv ntawm shielding roj nyob ntawm cov txheej txheem vuam, alloy muaj pes tsawg leeg, thiab qhov xav tau vuam kev ua tau zoo.
Zoo thiab ntawv pov thawj: Automotive thiab aerospace daim ntawv thov xav tau zoo welds nrog nruj kev xav tau rau lub zog, durability, thiab kev ntseeg tau. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tau xaiv cov txhuas vuam hlau uas ua tau raws li cov qauv kev lag luam thiab cov ntawv pov thawj, xws li AWS (American Welding Society) thiab ISO (International Organization for Standardization) kom ntseeg tau tias qhov zoo sib xws thiab txhim khu kev qha weld.
