WT 20 Tungsten electrodes Ansi/AWS A521 98

Product Overview

Description

Tungsten electrode WT-20

 

Standard:

ISO6848 ANSI/AWS

A5.12/A5.12M-98

 

Description:

High melting point, low arc ignition, good arc stability, non-consumable. Tungsten

electrode added 0.15-4% ThO2, CeO2, La2O3, ZrO2, which can reduce the burn-off

rate of electrode, prolong its service life, not pollute the welding seam, increase launching

ability of Tungsten electrode electrons with excellent welding appearance and quality.

 

Application:

Thorium-Tungsten Electrode is widely used as an additive oxide electrode ,having much more advanced comprehensive welding performance than the properties of Pure Tungsten Electrode and other additive oxide electrodes. It can not be replaced by other oxide electrodes during the long use process.

 

 It can be operated easily has a high current load and produce arc easily and steadily. In addition, the gap of the breaking arc is big ,loss less and life longer .It has  higher re-crystallized temperature, better conductivity and mechanical cutting property .

 

Now, Thorium-Tungsten Electrode is wildly used in welding carbon steel, stainless steel, nickel alloy and titanium metal. It becomes the first selection material for high quality welding.
