Koj puas tuaj yeem qhia qhov txawv ntawm TIG thiab MIG vuam?

TIG

1.Daim ntawv thov :

   TIG welding(tungsten argon arc welding) yog ib txoj kev vuam uas siv cov ntshiab Ar yog siv los tiv thaiv roj thiab tungsten electrodes yog siv los ua electrodes.TIG welding hlau yog nkag rau hauv cov kab ncaj nraim ntawm ib qho ntev (feem ntau lm).Inert gas shielded arc vuam siv cov ntshiab tungsten los yog activated tungsten (thoriated tungsten, cerium tungsten, zirconium tungsten, lanthanum tungsten) raws li cov tsis-melting electrode, siv lub arc nruab nrab ntawm lub tungsten electrode thiab lub workpiece los yaj cov hlau los tsim ib tug hlau.Lub tungsten electrode tsis yaj thaum lub sij hawm vuam thiab tsuas yog ua raws li ib tug electrode.Nyob rau tib lub sijhawm, argon lossis helium yog pub rau hauv lub nozzle ntawm lub teeb rau kev tiv thaiv.Cov hlau ntxiv kuj tuaj yeem muab ntxiv raws li qhov xav tau.Thoob ntiaj teb lub npe hu uaTIG welding.

2. Qhov zoo:

Lub ntsiab kom zoo dua ntawm TIG vuam txoj kev yog nws muaj peev xwm welding ntau yam ntaub ntawv.Xws li cov khoom ua haujlwm nrog lub thickness ntawm 0.6 hli thiab siab dua, cov ntaub ntawv muaj xws li alloy steel, aluminium, magnesium, tooj liab thiab nws cov alloys, grey cam khwb cia hlau, ntau yam bronzes, npib tsib xee, nyiaj, Titanium thiab txhuas.Lub ntsiab ntawm daim ntawv thov yog vuam ntawm nyias thiab nruab nrab thickness workpieces raws li ib tug hauv paus hla ntawm thicker seem.

3. Ceev faj: 

A. Shielding gas ntws yuav tsum: thaum vuam tam sim no ntawm 100-200A, nws yog 7-12L / min;Thaum lub vuam tam sim no nyob nruab nrab ntawm 200-300A, nws yog 12-15L / min.

B. Lub protruding ntev ntawm lub tungsten electrode yuav tsum luv li ntev raws li qhov ua tau ntawm lub nozzle, thiab lub arc ntev yuav tsum tau tswj feem ntau ntawm 1-4mm (2-4mm rau vuam carbon steel; 1-3mm rau welding low-alloy steel. thiab stainless hlau).

C. Thaum cua ceev ntau dua 1.0m / s, yuav tsum tau ntsuas qhov ntsuas cua;xyuam xim rau qhov cua kom tsis txhob raug mob rau tus neeg teb xov tooj.

D. nruj me ntsis tshem cov roj, xeb thiab noo noo impurities los ntawm vuam qhov chaw thaum vuam.

E. Nws raug nquahu kom siv DC fais fab mov nrog cov yam ntxwv sab nraud, thiab tus ncej tungsten yog qhov zoo heev.

F. Thaum vuam cov hlau tsis tshua muaj siab tshaj 1.25% Cr, sab nraub qaum yuav tsum tau tiv thaiv.

MIG

1. Daim ntawv thov:

   MIG vuamyog melting ncej inert gas shielded vuam.Nws siv Ar thiab lwm yam inert gases ua lub ntsiab shielding gas, xws li ntshiab Ar los yog Ar roj tov nrog ib tug me me npaum li cas ntawm active gases (xws li O2 qis dua 2% los yog CO2 qis dua 5%) rau melting.Txoj kev welding ntawm arc vuam.MIG hlau yog nkag rau hauv coils lossis coils hauv txheej.Txoj kev vuam no siv qhov kub hnyiab ntawm qhov txuas txuas txuas txuas txuas txuas thiab cov khoom ua haujlwm raws li cov cua sov, thiab cov roj ejected los ntawm lub teeb nozzle yog siv los tiv thaiv lub arc rau vuam.

 

2. Advantage:

Nws yog qhov yooj yim rau vuam nyob rau hauv ntau txoj haujlwm, thiab tseem muaj qhov ceev vuam ceev thiab qhov tso nyiaj ntau dua.MIG-shielded arc vuam siv tau rau vuam ntawm cov hlau loj, nrog rau cov hlau thiab hlau alloy.MIG arc vuam yog tsim rau stainless hlau, txhuas, magnesium, tooj liab, titanium, picks thiab npib tsib xee alloys.Arc chaw vuam kuj tuaj yeem ua tau siv txoj kev vuam no.

3. Ceev faj:

A. Kev tiv thaiv roj ntws zoo dua yog 20-25L / min.

B. Qhov ntev arc feem ntau yog tswj ntawm li 4-6mm.

C. Qhov cuam tshuam ntawm cua yog qhov tshwj xeeb tsis zoo rau vuam.Thaum cov cua ceev siab tshaj 0.5m / s, yuav tsum ntsuas cua tiv thaiv;xyuam xim rau qhov cua kom tsis txhob raug mob rau tus neeg teb xov tooj.

D.Kev siv cov pulsed arc tam sim no tuaj yeem tau txais cov tshuaj tsuag arc ruaj khov, tshwj xeeb tshaj yog tsim rau vuam ntawm stainless hlau, nyias phaj, ntsug welding thiab surfacing vuam.

E. Thov siv Ar + 2% O2 roj ua ke rau vuam ultra-low carbon stainless hlau, tsis txhob siv Ar thiab CO2 sib xyaw vuam hlau.

F. nruj me ntsis tshem cov roj, xeb thiab noo noo impurities ntawm qhov chaw vuam thaum vuam.a6efce1b9d16fdfa2d6af3ddb98f8c5494ee7bfa
