Karolo e ka sehloohong ea ho tjheseletsa TIG ke ho sebelisa pulse e laoloang hona joale ho futhumatsa mosebetsi.Ha molumo o mong le o mong oa sekhahla o feta, mosebetsi oa futhumatsa le ho qhibiliha ho etsa letamo le qhibilihisitsoeng.Ha botlaaseng ba metsi bo feta, letamo le qhibilihisitsoeng le hoholeha le ho phatsima le ho boloka mollo oa arc.Ka hona, ts'ebetso ea welding ke mokhoa oa ho futhumatsa oa nakoana, 'me weld e phahamisoa ke letamo le le leng le qhibilihisitsoeng.Ho feta moo, arc e ntse e phunya, e fapanyetsana ka arc e kholo le e khanyang ea pulsed arc le potoloho e nyane le e lefifi ea arc, 'me arc e na le ts'ebetso e hlakileng.

Pulse TIG welding e ka aroloa ka:

DC pulse TIG welding

AC pulse TIG welding.

Ho ea ka frequency, e ka aroloa ka:

1) Leqhubu le tlase 0.1 ~ 10Hz

2) Haeba 10 ~ 10000hz;

3) Maqhubu a phahameng 10 ~ 20kHz.

DC pulse TIG welding le AC pulse TIG welding li loketse lisebelisoa tse tšoanang tsa welding joalo ka TIG e tloaelehileng.

TIG welding ha e sebelisoe hangata tlhahisong e sebetsang hobane tšilafalo ea lerata e bakoang ke arc e matla haholo hore batho ba ka e utloa.Hangata ho sebelisoa li-welding tse tlaase le tse phahameng tsa TIG.

Pulse TIG welding e na le melemo e latelang:

1) Ts'ebetso ea tjheseletsa ke ho futhumala ha nakoana, nako ea ho lula ha mocheso o phahameng oa tšepe e qhibilihisitsoeng e khuts'oane, 'me tšepe e hola ka potlako, e ka fokotsang tšekamelo ea mapetsong a thepa e sa utloeng mocheso;The butt weldment e na le mocheso o fokolang oa mocheso, matla a arc a concentrated le ho satalla ho phahameng, e leng se loketseng ho cheselletsa poleiti e tšesaane le poleiti e tšesaane haholo, 'me lenonyeletso le na le tšusumetso e fokolang ea mocheso;Pulse TIG welding e ka laola ka nepo mocheso oa mocheso le boholo ba letamo la weld ho fumana ho kenella ka mokhoa o ts'oanang, kahoo e loketse bakeng sa ho tjheseletsa ka mahlakoreng a le mong, ho etsoa ka mahlakoreng a mabeli le ho tjheseletsa boemo bohle.Kamora hore maqhubu a pulse a fete 10kHz, arc e na le shrinkage e matla ea electromagnetic, arc e ba mosesaane mme e na le tataiso e matla.Ka hona, ho cheselletsa ka lebelo le phahameng ho ka etsoa, ​​​​'me lebelo la welding le ka fihla ho 30m / min;

4) Oscillation e phahameng-frequency oscillation ea pulsed TIG welding e thusa ho fumana microstructure e feletseng ea lijo-thollo tse ntle, ho felisa li-pores le ho ntlafatsa thepa ea mochine oa motsoako.
