Eyona nto iphambili ye-pulse TIG welding kukusebenzisa i-pulse elawulwayo yangoku ukutshisa i-workpiece.Xa i-pulse current nganye idlula, umsebenzi uyafudunyezwa kwaye unyibilike ukwenza ichibi elinyibilikisiweyo.Xa isiseko sangoku sidlula, ichibi elityhidiweyo liyajiya kwaye likhazimle kwaye ligcine ukuvutha kwearc.Ke ngoko, inkqubo ye-welding yinkqubo yokufudumala ephakathi, kwaye i-weld iphakanyiswe yi-pool enye etyhidiweyo.Ngaphaya koko, i-arc iyajikeleza, itshintshana nge-arc enkulu kunye eqaqambileyo kunye nomjikelo omncinci kunye nomnyama we-arc, kwaye i-arc ine-flicker ecacileyo.

I-Pulse TIG welding inokwahlulwa ibe:

DC pulse TIG welding

AC pulse TIG welding.

Ngokwe-frequency, inokwahlulwa ibe:

1) Ukuphindaphinda okuphantsi 0.1 ~ 10Hz

2) Ukuba 10 ~ 10000hz;

3) I-frequency ephezulu 10 ~ 20kHz.

I-DC pulse TIG welding kunye ne-AC pulse TIG welding zilungele izinto zokuwelda ezifanayo njenge-TIG yesiqhelo yokuwelda.

Ukuwelda okuphakathi kwe-TIG akufane kusetyenziswe kwimveliso ebonakalayo kuba ungcoliseko lwengxolo olubangelwa yi-arc lunamandla kakhulu ukuba lungaviwa ngabantu.I-low frequency kunye ne-high frequency ye-TIG welding idla ngokusetyenziswa.

I-Pulse TIG welding inezi zibonelelo zilandelayo:

I-1) Inkqubo ye-welding kukufudumala okuphakathi, ixesha lokuhlala lobushushu eliphezulu lesinyithi esityhidiweyo sesinyithi sifutshane, kwaye isinyithi sidibanisa ngokukhawuleza, esinokunciphisa ukuthambekela kweentanda kwizinto ezithintekayo kubushushu;I-butt weldment inegalelo elincinci lobushushu, amandla e-arc agxininisiweyo kunye nokuqina okuphezulu, okulungelelaniswa ne-welding ye-plate encinci kunye ne-ultra-thin plate, kwaye i-joint inempembelelo encinci ye-thermal;I-Pulse TIG welding inokulawula ngokuchanekileyo igalelo lobushushu kunye nobukhulu be-weld pool ukufumana ukungena okufanayo, ngoko ifanelekile ukuwelda okusecaleni, ukubunjwa kwamacala amabini kunye nayo yonke indawo ye-welding.Emva kokuba i-pulse yangoku iphindaphindeka ngaphezu kwe-10kHz, i-arc ine-electromagnetic shrinkage eyomeleleyo, i-arc iba bhityileyo kwaye ibe ne-directivity eyomeleleyo.Ngoko ke, i-welding ye-high-speed ingenziwa, kwaye isantya se-welding sinokufikelela kwi-30m / min;

I-4) I-oscillation ye-high-frequency oscillation ye-pulsed TIG welding ilungele ukufumana i-microstructure yesigaba esipheleleyo se-grains emihle, ukuphelisa ii-pores kunye nokuphucula iimpawu zemishini yokudibanisa.
