Vuam stainless hlau ntawv hlau yog ib qho kev coj ua hauv ntau qhov kev lag luam, suav nrog tsheb, aerospace, thiab kev tsim kho. Nws yog ib qho tseem ceeb kom nkag siab txog cov txheej txheem tsim nyog thiab cov txheej txheem rau welding hom ntawv hlau kom ntseeg tau tias muaj zog thiab ruaj khov. Hauv tsab xov xwm no, peb yuav tham txog ntau yam ntawm cov hlau tsis muaj steel, cov txheej txheem vuam, thiab cov khoom siv yuav tsum tau ua tiav vuam stainless hlau ntawv hlau.
Hom Stainless Hlau
Stainless hlau yog ib hom hlau uas muaj tsawg kawg yog 10.5% chromium. Cov chromium hauv cov hlau tsim cov txheej txheem oxide tiv thaiv ntawm cov hlau, uas pab tiv thaiv corrosion. Muaj ntau ntau hom stainless hlau, txhua tus muaj cov khoom sib txawv thiab siv. Feem ntau hom stainless hlau siv hauv cov ntawv hlau vuam yog:
►Austenitic Stainless Steel - Hom stainless hlau no feem ntau siv thiab siv ntau yam kev siv. Nws tsis yog-sib nqus thiab muaj qhov zoo weldability, ua rau nws yog qhov kev xaiv nrov rau cov ntawv hlau vuam.
► Ferritic Stainless Steel - Hom stainless hlau no yog sib nqus thiab muaj kev tiv thaiv qis dua li austenitic stainless hlau. Nws yog feem ntau siv nyob rau hauv automotive tso systems thiab lwm yam kev siv qhov twg corrosion kuj tsis yog thawj qhov kev txhawj xeeb.
►Martensitic Stainless Steel - Hom stainless hlau no yog sib nqus thiab muaj zog thiab hardness. Nws yog feem ntau siv hauv cutlery, riam, thiab lwm yam cuab yeej.
Vuam txheej txheem
Cov txheej txheem vuam feem ntau siv rau vuam stainless hlau ntawv hlau yog roj tungsten arc vuam (GTAW), tseem hu ua tungsten inert gas (TIG) vuam. GTAW yog cov txheej txheem vuam zoo uas ua kom huv thiab meej welds. Nws kuj tseem tsim nyog rau vuam ntau yam khoom siv, suav nrog cov hlau tsis muaj steel.
Ua ntej pib cov txheej txheem vuam, nws yog ib qho tseem ceeb uas yuav tsum tau ntxuav qhov saum npoo ntawm cov hlau stainless hlau kom huv si. Txhua yam av, roj, lossis lwm yam kab mob ntawm qhov chaw tuaj yeem ua rau lub vuam tsis muaj zog. Tom qab ntxuav, cov ntawv hlau yuav tsum tau clamped kom ruaj ntseg kom tsis txhob muaj kev txav mus los thaum lub vuam txheej txheem.
TIG welding txheej txheem yuav tsum tau siv ib tug tungsten electrode los tsim ib tug arc ntawm lub electrode thiab lub workpiece. Tom qab ntawd ib lub pas nrig muab ntxiv rau qhov arc los tsim cov vuam. Tus neeg teb xov tooj vuam yuav tsum tswj cov cua kub nkag thiab mus ncig ceev kom ntseeg tau tias muaj zog thiab sib xws.
Khoom siv yuav tsum tau
Txhawm rau welding stainless hlau ntawv hlau, yuav tsum muaj ntau yam khoom siv, suav nrog:
●Tungsten Electrode - Qhov no yog cov khoom siv hluav taws xob siv hauv GTAW txheej txheem los tsim cov arc ntawm cov electrode thiab cov khoom ua haujlwm.
●Filler Rod - Cov pas nrig muab tub lim yog siv los ntxiv cov khoom siv rau hauv cov vuam thiab tsim kom muaj kev sib koom ua ke ntawm ob daim hlau stainless hlau.
●Welding Torch - Lub vuam teeb yog siv los coj cov cua sov los ntawm arc mus rau qhov chaw ua haujlwm.
● Gas Shielding - Txhawm rau tiv thaiv cov vuam los ntawm oxidation thiab lwm yam kab mob, siv cov ntaub thaiv npog roj thaum lub sijhawm vuam. Argon feem ntau yog siv los ua cov roj tiv thaiv hauv TIG vuam.
Piv txwv
Txhawm rau muab ib qho piv txwv ntawm cov txheej txheem vuam, cia peb xav tias peb tau vuam ob daim ntawm 304 stainless hlau ntawv hlau ua ke.
► Ua ntej, peb yuav ntxuav qhov saum npoo ntawm cov ntawv hlau kom huv si kom tshem tawm cov kab mob. Tom qab ntawd, peb yuav clamp ob daim ntawv hlau ruaj ntseg rau hauv qhov chaw.
►Tom ntej no, peb yuav npaj cov khoom siv vuam TIG, suav nrog cov tungsten electrode, muab tub lim, vuam teeb, thiab roj tiv thaiv. Peb yuav teeb tsa cov cua sov kom tsim nyog thiab kev mus los nrawm raws li qhov tuab ntawm cov ntawv hlau thiab qhov xav tau lub zog weld.
►Thaum cov cuab yeej npaj tau, peb yuav pib txheej txheem vuam, tsim ib qho arc ntawm tungsten electrode thiab workpiece. Tom qab ntawd peb yuav ntxiv cov pas nrig rau lub arc, tsim kom muaj zog thiab zoo sib xws ntawm ob daim ntawv hlau. Thoob plaws hauv cov txheej txheem vuam, peb yuav xyuas kom meej tias cov cua kub nkag thiab kev mus los ceev tau tswj xyuas kom tsim tau cov vuam zoo.
►Tom qab cov txheej txheem vuam tiav lawm, peb yuav tso cai rau cov hlau tsis muaj steel hlau kom txias maj mam kom tsis txhob muaj kev sib tsoo lossis tawg. Thaum cov hlau tau txias lawm, peb yuav tshuaj xyuas qhov vuam ntawm qhov tsis xws luag lossis tsis zoo, xws li tawg lossis porosity. Yog tias pom muaj qhov tsis xws luag, peb yuav tsum rov weld cov chaw cuam tshuam kom ntseeg tau tias muaj zog thiab ruaj khov.
Hauv kev xaus, welding stainless hlau ntawv hlau yog ib qho kev coj ua hauv ntau qhov kev lag luam, thiab nws yog ib qho tseem ceeb kom nkag siab txog cov txheej txheem tsim nyog thiab cov txheej txheem los tsim kom muaj zog thiab ruaj khov. Cov txheej txheem vuam feem ntau siv rau vuam stainless hlau ntawv hlau yog roj tungsten arc vuam (GTAW), thiab nws yuav tsum tau siv ob peb yam khoom, suav nrog tungsten electrode, muab tub lim, vuam teeb, thiab roj shielding. Los ntawm kev ua raws li cov txheej txheem tsim nyog thiab siv cov cuab yeej tsim nyog, peb tuaj yeem tsim cov welds zoo uas ua tau raws li cov kev cai nruj ntawm ntau yam kev lag luam.
