Isici esiyinhloko se-pulse TIG welding ukusebenzisa i-pulse current elawulekayo ukushisa i-workpiece.Lapho ukushaya kwenhliziyo ngakunye kudlula, umsebenzi uyashisisa futhi uncibilike ukuze kwakheke ichibi elincibilikisiwe.Lapho isisekelo samanje sidlula, ichibi elincibilikisiwe liyajiya futhi licwebezele futhi ligcine ukuvutha kwe-arc.Ngakho-ke, inqubo yokushisela iyinqubo yokushisisa ngezikhathi ezithile, futhi i-weld ibekwe ngaphezu kwechibi elilodwa elincibilikisiwe.Ngaphezu kwalokho, i-arc iyaphephuka, ishintshana nge-arc enkulu negqamile eshayayo kanye nomjikelezo we-arc hlangothi oluncane olumnyama, futhi i-arc inezinto ezicwayizayo ezisobala.

I-Pulse TIG welding ingahlukaniswa ibe:

I-DC pulse TIG welding

I-AC pulse TIG welding.

Ngokusho kwe-frequency, ingahlukaniswa ibe:

1) Imvamisa ephansi 0.1 ~ 10Hz

2) Uma 10 ~ 10000hz;

3) Imvamisa ephezulu 10 ~ 20kHz.

I-DC pulse TIG welding kanye ne-AC pulse TIG welding ifanele izinto zokushisela ezifanayo njengokushisela okujwayelekile kwe-TIG.

Ukushisela kwe-TIG okuvama okumaphakathi akuvamile ukusetshenziswa ekukhiqizeni okungokoqobo ngoba ukungcoliswa komsindo okubangelwa i-arc kunamandla kakhulu ukuthi abantu bangezwa.Imvamisa ephansi kanye ne-TIG welding ephezulu ivame ukusetshenziswa.

I-Pulse TIG welding inezinzuzo ezilandelayo:

I-1) Inqubo yokushisela ukushisa okuphakathi, isikhathi sokuhlala sokushisa esiphezulu sensimbi encibilikisiwe yensimbi sifushane, futhi insimbi iyajiya ngokushesha, enganciphisa ukuthambekela kokuqhekeka ezintweni ezizwela ukushisa;I-butt weldment inokufaka okuncane kokushisa, amandla e-arc agxilile kanye nokuqina okuphezulu, okulungele ukushiselwa kwepuleti elincanyana kanye nepuleti elincanyana kakhulu, futhi ukujoyina kunomthelela omncane wokushisa;I-Pulse TIG welding ingalawula ngokunembile okokufaka kokushisa kanye nosayizi we-weld pool ukuze kutholwe ukungena okufanayo, ngakho ifanelekela ukushisela ohlangothini olulodwa, ukwakheka okukabili kanye nakho konke ukushisela indawo.Ngemuva kokuthi imvamisa yamanje ye-pulse yeqe ku-10kHz, i-arc inokuncipha okuqinile kozibuthe kagesi, i-arc iba mncane futhi ibe nokuqondisa okuqinile.Ngakho-ke, i-welding high-speed ingenziwa, futhi isivinini sokushisela singafinyelela ku-30m / min;

I-4) I-oscillation ye-high-frequency oscillation ye-pulsed TIG welding isiza ukuthola i-microstructure yesigaba esigcwele sokusanhlamvu okuhle, ukuqeda ama-pores kanye nokuthuthukisa izakhiwo zemishini yokuhlangana.
