1.Vim li cas qhov chaw weld lub zog ntawm tin - plated steel ntawv qis?
Tsawg- melting-point, qis-resistivity cuam tshuam txheej:
Tin muaj ib tug melting point ntawm tsuas yog 232 degree, thaum hlau muaj ib tug melting point ntawm kwv yees li 1500 degree. Thaum pib, thaum siv tam sim no, cov tin txheej melts instantaneously, ua rau muaj kev hloov pauv loj thiab tsis ruaj khov hauv qhov chaw sib cuag thiab kev sib cuag ntawm ob daim hlau.
Tin's resistivity yog qis dua cov hlau, uas ua rau qee qhov tam sim no hloov mus los ntawm txheej txheej tin, txo cov cua kub zoo rau kev tsim cov hlau -rau- steel weld nugget.
Qhov nyuaj hauv weld nugget tsim:
Qhov zoo tshaj plaws weld nugget yuav tsum yog "fusion nugget" tsim los ntawm kev sib xyaw ntawm ob cov ntaub ntawv hlau. Txawm li cas los xij, molten tin paug qhov kev sib cuag, cuam tshuam ncaj qha fusion ntawm cov hlau thiab hlau. Nyob rau tib lub sijhawm, molten tin tuaj yeem raug nyem ib ncig ntawm lub weld nugget, ua "ntiv nplhaib- zoo li daim ntawv cog lus," zoo li welded, tab sis nrog ib tug me me los yog tsis muaj core steel - mus rau - steel fusion cheeb tsam (hu ua "txias weld").
Qhov no tsis tiav los yog tsis sib xws weld nugget ncaj qha ua rau txo qhov load-cov kabmob thiab txo lub zog.
Yooj yim rau spatter thiab defects:
Vim tias cov txheej txheem melting tsis ruaj khov ntawm cov tin txheej, nws yog ib qho yooj yim los ua instantaneous vaporization los yog hlau spatter, tawm hauv qhov tsis xws luag xws li qhov thiab cov kab nrib pleb nyob rau hauv lub solder nugget, ntxiv tsis muaj zog nws lub zog.
2.Thaum nrhiav kev siv zog, yuav tsum xaiv li cas?
Rau cov khoom sib xyaw thiab thauj khoom-cov kabmob (xws li lub cev lub cev, cov khoom siv chassis, thiab cov txee thav duab), txias- dov coils lossis lawv qhov txawv (xws li siab- lub zog steel, welded ua ntej galvanizing) yuav tsum tau siv los xyuas kom muaj kev ntseeg tau thiab kev nyab xeeb ntawm cov pob qij txha.
3.Thaum twg yog qhov yuav tsum tau siv cov tin- plated phaj?
Hard - Specification soldering: Ua haujlwm siab tam sim no thiab luv luv -lub sij hawm soldering tsis. Lub hom phiaj yog kom sai sai ua kom muaj cua sov txaus hauv cov phaj hlau los ua ib qho weld nugget ua ntej txheej tin tag nrho melts thiab ua rau muaj kev cuam tshuam loj heev.
Precise control: Yuav tsum muaj cov tshuab vuam ntau dua thiab cov ntsuas ntsuas.
Electrode tswj: Tin yooj yim ua raws li cov lus qhia electrode, ua rau electrode paug thiab deformation, yuav tsum tau sib tsoo ntau zaus thiab tu.
Lub zog xav tau: Txawm tias muaj cov txheej txheem ua kom zoo, qhov vuam lub zog feem ntau tsuas yog 60% -80% ntawm cov hlau txias-kuav los tiag ntawm tib tuab, nrog qhov sib txawv tseem ceeb. Tus tsim yuav tsum tau nce tus naj npawb ntawm cov ntsiab lus weld los yog siv lwm txoj hauv kev ntxiv dag zog.
4.Dab tsi yog qhov sib txawv ntawm qhov ua tiav ntawm qhov txias -rolled coils thiab tin- cov ntawv plated?
Txias-rolled coil: huv si, liab qab steel nto, tejzaum nws nrog lub teeb daim ntawv thov ntawm anti- xeb roj.
Tinplate: Nto yog txheej tin (thiab tin - hlau alloy txheej), feem ntau yog nrog cov zaj duab xis passivation thiab roj nplua nyeem.
5.Lub hauv paus ntsiab lus yog dab tsi thaum xaiv?
Yog tias lub zog vuam yog qhov tseem ceeb, qhov chaw vuam nrog tinplate yuav tsum zam; Yog tias tinplate yuav tsum tau siv vim qhov yuav tsum tau muaj xws li kev tiv thaiv corrosion, nws lub zog qis qis yuav tsum tau txais thiab ua kom zoo dua los ntawm kev tswj xyuas nruj.
