Tuam Tshoj welding electrode 2% cerium WC20 cerium tungsten electrode Chaw tsim tshuaj paus thiab tsum

Vuam electrode 2% cerium WC20 cerium tungsten electrode

Lus piav qhia luv luv:

Cerium tungsten electrodes feem ntau yog siv rau TIG vuam vim lawv ua tau zoo nyob rau hauv ob qho tib si AC thiab DC vuam daim ntaub ntawv. Lawv paub txog lawv qhov zoo tshaj plaws arc stability, zoo ignition yam ntxwv, thiab kev ua tau zoo ib yam ntawm qis amperage, ua rau lawv haum rau nyias cov ntaub ntawv thiab complex welds.

Cov xim dab tsi yog tungsten nrog 2% Ceria?

Tungsten yog ua ke nrog 2% ceria los tsim tungsten-cerium oxide composite uas feem ntau yog siv los ua lwm yam tsis muaj hluav taws xob rau thoriated tungsten electrodes hauv kev siv vuam.

Cov xim ntawm tungsten uas muaj 2% ceria tuaj yeem sib txawv tab sis feem ntau yog lub teeb grey lossis xim dawb. Qhov ntxoov ntxoo tshwj xeeb yuav nyob ntawm seb yam xws li cov txheej txheem tsim khoom thiab cov txheej txheem ntxiv lossis kev kho mob siv rau cov khoom siv.

Qhov txawv ntawm Thoriated thiab Ceriated tungsten yog dab tsi?

Thoriated tungsten thiab cerium tungsten yog ob qho tib si tungsten electrodes rau vuam, tab sis lawv muaj ntau yam sib txawv thiab cov khoom:

1. Thoriated tungsten:
-Thoriated tungsten electrodes muaj me me ntawm thorium oxide (feem ntau yog li 1-2%). Qhov sib ntxiv ntawm thorium txhim kho cov qauv hluav taws xob emission ntawm cov electrode, ua kom yooj yim pib thiab tswj cov vuam arc.
-Thoriated tungsten paub txog nws lub peev xwm nqa tam sim no, zoo arc stability thiab lub neej ntev. Nws yog feem ntau siv hauv DC vuam daim ntawv thov, tshwj xeeb tshaj yog rau vuam cov ntaub ntawv xws li carbon steel, stainless hlau, npib tsib xee alloys thiab titanium.

2. Tungsten cerium:
- Cerium tungsten electrodes muaj cerium oxide ua cov khoom siv hlau. Feem ntau cerium tungsten compositions muaj 1.5-2% cerium oxide.
- Cerium tungsten muaj qhov pib zoo thiab ruaj khov, tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov vuam qis tam sim no. Nws yog tsim rau AC thiab DC vuam thiab yog li tsim nyog rau ntau yam ntaub ntawv thiab vuam txheej txheem.
- Cerium tungsten feem ntau raug xaiv los ua lwm txoj hauv kev tsis muaj hluav taws xob rau thorium tungsten los daws cov kev txhawj xeeb txog kev pheej hmoo ntawm kev noj qab haus huv cuam tshuam nrog thorium raug.

Hauv cov ntsiab lus, thaum ob qho tib si thoriated tungsten electrodes thiab cerium tungsten electrodes siv hauv vuam, lawv muaj ntau yam sib txawv thiab tsim nyog rau kev siv vuam sib txawv thiab cov xwm txheej. Thoriated tungsten paub txog nws lub peev xwm nqa tam sim no thiab feem ntau siv hauv DC vuam, thaum cerium tungsten muaj qhov pib zoo thiab ruaj khov thiab haum rau AC thiab DC vuam.

Puas yog 2% thoriated tungsten radioactive?

Yog lawm, 2% thoriated tungsten electrodes yog suav tias yog me ntsis xov tooj cua vim muaj cov thorium oxide nyob rau hauv cov electrode muaj pes tsawg leeg. Thorium yog ib yam khoom siv hluav taws xob uas tshwm sim nyob rau hauv tungsten electrodes uas emits qis qis alpha hais. Txawm hais tias cov xov tooj cua muaj tsawg tsawg, nws tseem ceeb heev uas yuav tsum tau ua kom zoo thiab pov tseg ntawm thoriated tungsten electrodes kom txo tau qhov tshwm sim.

Vim yog cov xov tooj cua ntawm thorium, kev siv, tuav thiab pov tseg ntawm thorium tungsten electrodes xav tau kev nyab xeeb thiab kev tswj xyuas. Raws li qhov tshwm sim, muaj kev hloov pauv mus rau lwm yam tsis muaj hluav taws xob xws li tungsten cerium, tungsten lanthanate lossis lwm yam tsis tshua muaj hauv ntiaj teb doped tungsten electrodes, tshwj xeeb tshaj yog nyob rau hauv kev lag luam uas cov neeg ua haujlwm kev nyab xeeb thiab kev txhawj xeeb ib puag ncig yog qhov tseem ceeb.
