Lub ntsiab feature ntawm pulse TIG vuam yog siv cov mem tes tswj tau tam sim no kom sov lub workpiece.Thaum txhua tus mem tes tam sim no dhau mus, kev ua haujlwm yog rhuab thiab yaj los ua ib lub pas dej molten.Thaum lub hauv paus tam sim no dhau mus, lub pas dej molten condenses thiab crystallizes thiab tswj arc combustion.Yog li ntawd, cov txheej txheem vuam yog ib qho txheej txheem cua sov sib cuam tshuam, thiab cov vuam yog superimposed los ntawm ib lub pas dej molten.Ntxiv mus, lub arc yog pulsating, alternating los ntawm loj thiab kaj pulsed arc thiab me me thiab tsaus nti arc voj voog, thiab lub arc muaj pom tseeb flicker phenomenon.

Pulse TIG vuam tuaj yeem muab faib ua:

DC pulse TIG welding

AC pulse TIG welding.

Raws li qhov zaus, nws tuaj yeem muab faib ua:

1) Tsawg zaus 0.1 ~ 10Hz

2) Yog 10 ~ 10000hz;

3) High zaus 10 ~ 20kHz.

DC pulse TIG vuam thiab AC mem tes TIG vuam yog tsim rau tib cov ntaub ntawv vuam zoo li TIG vuam zoo tib yam.

Nruab nrab zaus TIG vuam yog tsis tshua muaj siv nyob rau hauv cov tswv yim ntau lawm vim hais tias cov suab nrov muaj kuab paug los ntawm arc muaj zog heev rau tib neeg lub rooj sib hais.Tsawg zaus thiab siab zaus TIG vuam feem ntau yog siv.

Pulse TIG vuam muaj qhov zoo hauv qab no:

1) Cov txheej txheem vuam yog qhov sib cuam tshuam cua sov, lub sijhawm nyob hauv qhov kub thiab txias ntawm lub pas dej ua ke hlau yog luv luv, thiab cov hlau condenses sai sai, uas tuaj yeem txo qhov kev nyiam ntawm cov kab nrib pleb hauv cov ntaub ntawv kub;Lub pob tw weldment muaj cov cua kub tsawg dua, muaj zog arc zog thiab siab tawv, uas yog qhov zoo rau kev vuam ntawm nyias phaj thiab ultra-thin phaj, thiab cov sib koom ua ke muaj kev cuam tshuam thermal me ntsis;Pulse TIG welding tuaj yeem tswj tau cov cua sov thiab qhov loj ntawm lub pas dej kom tau txais kev nkag mus zoo ib yam, yog li nws tsim nyog rau kev vuam ib leeg, ob sab sib sau thiab txhua txoj haujlwm vuam.Tom qab cov mem tes tam sim no ntau tshaj 10kHz, lub arc muaj zog electromagnetic shrinkage, lub arc yuav thinner thiab muaj zog directivity.Yog li ntawd, kev kub ceev vuam tuaj yeem nqa tau, thiab vuam ceev tuaj yeem ncav cuag 30m / min;

4) Lub siab zaus oscillation ntawm pulsed TIG welding yog qhov tsim nyog kom tau txais tag nrho-theem microstructure ntawm cov nplej zoo, tshem tawm qhov pores thiab txhim kho cov khoom siv ntawm kev sib koom ua ke.
