Qhov txawv ntawm cov MIG vuam thiab TIG vuam


MIG vuam (inert gas hlau arc vuam)

Ntxiv rau cov MIG vuam tsau tsis tungsten electrode nrog cov nyob ntawm tej xov. Lwm yam thiab TIG vuam. Yog li ntawd, cov hlau welding melted los ntawm arc, thiab xa tuaj rau hauv qhov chaw welding. Hwj huam uas tau tsav cov menyuam raws li welding tus hlau yuav tsum tau mus ua welding teeb los ntawm cov lus.

Qhov kub tseem DC arc, tab sis cov polarity thiab TIG vuam siv nyob rau hauv cov lus rov. Cov tiv roj siv no kuj txawv, thiaj li yuav txhim khu lub stability ntawm lub arc los ntawm kev ntxiv l % nqa pa mus rau hauv lub argon gas.

Tseem muaj ib txhia sib txawv me ntsis hauv tus txheej txheem basic, piv txwv, tshuaj tsuag, mem tes txhaj, pob thiab luv Circuit Court hloov.


TIG vuam - ua hauj lwm tso

TIG vuam kub tsub rau cov DC arc vuam voltage ua hauj lwm ntawm 10 mus rau 15 volts, tiam sis cov chaw li 300, cov workpiece li cathode, teeb nyob hauv lub tungsten electrode ua tus anode.

Roj inert yog feem ntau argon.

Inert roj mus teeb rau arc thiab weld pas ua ncig daim ntaub thaiv npog. Thiaj li yuav ua rau kom cov tswv yim thaum tshav kub kub, 5% hydrogen yog feem ntau ntxiv rau lub argon. Tiam sis, thaum hlau stainless ferritic welded, nws tseem tsis tau mus ua hydrogen ntxiv nyob rau argon. Cov roj noj yog li 8 rau 10 liters ib feeb xwb. In the Process of vuam tsuas yog los ntawm muaj tshuab cov pa vuam teeb inert, roj los zoo weld kev tiv thaiv rau cov tshuab weld.

Yog hais tias yuav tsum tau, lub qub welding hlau, uas yog lawm ua tus sau nyob rau hauv lub pas weld ntawm lub weld pas, tau lawm ua tus sau nrog cov khoom tib yam li austenitic cov ntaub welded.
