Welding txhuas tuaj yeem yog cov haujlwm nyuaj, vim nws muaj kev paub txog kev sib tw thiab cov lus qhia tseem ceeb, koj tuaj yeem taug kev los pib nrog vuam aluminium .
Nkag siab Aluminium
Tooj dawbyog ib lub teeb yuag, cov hlau uas tsis yog-suab nrov nrog cov txheej txheem oxidation, uas tuaj yeem tsim qhov tseem ceeb rau tshem tawm nws ua ntej koj pib .
Cov Cuab Yeej Tseem Ceeb thiab Khoom Siv
Yuav kom weld txhuas ntse, koj yuav xav tau cov hauv qab no:
- TIG Welder: Tungsten inert roj (tsov) vuam yog txoj kev ntau tshaj plaws rau vuam aluminium vim nws qhov tseeb thiab tswj .
- Lo ntaub qhwv: Rau thicker aluminium, koj tuaj yeem siv tus tuav lo nyias nrog lub ntsej muag tshuab vuam .
- Hlau txhuam thiab ib qho sib tsoo: Kom tshem tawm cov oxide txheej los ntawm aluminium nto .
- CHONPING Rauj: Txhawm rau tshem tawm cov khoom siv tawv me lossis cov roj oxide oli.
Cov iav kom tsim nyog: Suav nrog cov vuam kaus mom hlau nrog qhov ntxoov ntxoo nrog txoj kev ntxoov ntxoo haum rau txhuas cov hnab looj tes, hnab looj tes, thiab lub tsho vuam {}}
Npaj cov txhuas
Ua ntej koj pib vuam, nws yog ib qho tseem ceeb kom npaj cov npoo txhuas:
- Ntxuav lub nplaim: Siv cov hlau txhuam los yog txoj hlua sib dhos kom tshem tawm cov av, roj, lossis oxide txheej los ntawm aluminium .
- Deoxidize: Siv cov tshuaj tua kab los yog cov tshuaj deoxidizer kom tshem tawm cov seem oxide .
Ntsig cov txhuas: Preheat lubtooj dawbrau qhov kub tsawg los txo qhov kev pheej hmoo ntawm oxidation thaum lub sij hawm vuam .
Vuam cov txheej txheem
Ntawm no yog qee cov lus qhia dav dav rau vuam aluminium:
Kev nyiam huv yog tus yuam sij: Kom cov txhuas dawb ntawm cov kev paug ua ntej koj pib vuam .
Siv txoj cai amperage: Pib nrog qis dua amperage dua li koj yuav rau hlau los tiv thaiv kev hlawv cov hlawv los ntawm txhuas.
Taug kev ntawm lub nrawm: Txav mus rau qhov chaw tsim hluav taws xob lossis tus pas nrig ntawm txoj kev sib nciab kom tsis txhob muaj kev kub ntxhov lossis nkag siab txog cov ntaub ntawv .
Kev xyaum: Tooj dawbvuam yuav tsum tau siv cov ntaub ntawv sib tsoo thiab kev sib koom tes zoo ntawm qhov muag ua ntej ua haujlwm rau ntawm qhov project.
Tom qab vuam
Tom qab koj tau ua tiav chav Weld, muaj ob pebcov kauj ruamYuav kom ntseeg tau tias qhov zoo ntawm koj txoj haujlwm:
- Txias: Tso cai rau Weld kom txias ib txwm muaj los tiv thaiv distortion .
- Tshawb xyuas Weld: Saib rau cov kab nrib pleb, porosity, lossis tsis muaj fusion .
Ntxuav cov weld: Tshem tawm ib qho slag lossis cov khoom seem nrog cov hlau txhuam lossis chwing rauj .
Kev ceev faj kev nyab xeeb
- Lub cev muaj kev nyab xeeb uas tsim nyog, nrog rau cov hnab looj tes qhib lub hnab looj tes, hnab looj tes, thiab cov hluav taws kub-resistant .
- Ua haujlwm nyob rau hauv ib cheeb tsam zoo-ventilated kom tsis txhob nqus tau pa |.
- Khaws lub tua hluav taws nyob ze thaum muaj xwm txheej ceev .
