Tungsten electrodes - ib tug tseem ceeb ib feem ntawm lub arc welding.

Ib tug tungsten electrode rau Vuam pas nrig yog coated nrog ib tug tshwj xeeb txheej (los yog tsis muaj nws). Lub electrode hlau tej zaum yuav txawv los ntawm cov nram qab no nta:

1. Qhov ntev ntawm tus pas nrig.
2. Cov kab uas hla ntawm lub pas nrig.
3. Tshuaj nyob tus yeees. Nws muaj ib tug tseem ceeb feem rau qhov zoo cov yam ntxwv ntawm cov weld, thiab kuj pab txoj kev arc stability thiab los tiv thaiv cov hlau los ntawm ib puag ncig influences. Txij li thaum tungsten electrodes tej zaum yuav loj nrog ib tug ntxiv txheej los txhim kho no los yog lwm yam zoo txawv alloying, tshuab, slag, deoxidizing thiab stabilizing txheej.
4. Electrode hom. Tungsten electrodes yog sawv cev xwb nyob rau hauv qhov kev kawm ntawm uas tsis yog-consumable. Zoo cov yam ntxwv ntawm no hom ntawm electrodes tso cai rau lawv ua tus khaws cov zoo thaum lub sij hawm tag nrho vuam txoj kev. Txawm li cas los, nws yuav tsum tau nco ntsoov tias twb nyob rau hauv cov ntaub ntawv no, siv ib tug ntxiv muab tub lim khoom uas yog fused rau lub welded qhov chaw, txoj kev nrog lawv ib qho weld pas dej ua ke.

Tungsten electrodes yog xam tau tias yog ib tug ntawm cov tseem ceeb tshaj plaws hais nyob rau hauv lub arc welding. Txij li thaum tus txheej txheem no yuav melting cov khoom los ntawm txoj kev thermal zog, uas los ntawm lub arc paug generated ntawm lub electrode thiab lub workpiece. Lub arc - muaj hwj huam qhov hluav taws xob paug uas tshwm sim nyob rau hauv lub medium ntawm ionized roj thiab hlau vapor.

Yog li, lub tungsten electrodes pab raws li tam sim no conductors nyob rau hauv lub vuam tsam thiab los ntawm cov muab tub lim cov ntaub ntawv uas muab ob peb qhov chaw ua ke. Siv ntawm no hom ntawm electrodes txhawb lub tsim ntawm high-zoo leeg (tsis hais txog ntawm cov khoom ntawm welded qhov chaw).

Tungsten electrodes ua los ntawm tungsten hlau nrog tshwj xeeb additives uas muaj ib tug zoo ntxim rau qhov zoo ntawm cov weld.

Lub ignition ntawm lub fais arc nyob rau hauv lub vuam tsam tshwm sim nyob rau hauv ob peb theem:

1. Ua ntej, muaj ib tug luv luv Circuit Court tam sim no ntws los ntawm tus electrode mus rau lub workpiece.
2. Lub electrode tsiv tseg ib me ntsis, ncab ib ce lub arc.
3. ib tug ruaj khov arc yog ib tug ntawm cov manipulations.

Txawm li cas los, qhov no kev theem ntawm cov txheej txheem thiab yog ib tug disadvantage ntawm kev siv tungsten electrode: zoo txaus zazhigaemost arc tawm. Yuav kom tshem tawm tungsten electrodes coated nrog ib tug zirconium txheej.

Nyob rau hauv no hais txog, rau qhov tungsten electrodes muaj cov nram qab no:

1. Tsis tshua muaj melting tus nqi.
2. Ib tug tsawg degree ntawm deformation ntawm lub electrode.
3. Stability ntawm lub arc tawm.
4. Saj zawg zog daim ntawv thov.
5. Khov kho tam sim no.

Niaj hnub nimno tungsten electrodes muaj zoo zoo nta, uas muab siab arc thiab yog li ntawd kom zoo weld. Nrog txoj kev uas cais flickering ntawm lub arc paug, ib tug high degree ntawm arc stabilization.
