Composite Tungsten Electrodes

WE3 composite tungsten electrodes Along with the various tungsten electrode industrial developing ,the composite tungsten electrode becoming more and more popular ,especially about the W-E3 tungsten electrode .today we will introduce the advantages of composite tungsten.

W-E3 Tungsten Electrodes for AC or DC Welding

W-E3 Composite Tungsten Electrodes work well on AC or DC. They can be used DC electrode positive or negative with a pointed end, or balled for use with AC power sources.

W-E3 Tungsten Electrodes Have Minimum Impact on Your Process Documentation and Code Compliance

For operations concerned with AWS and ASME code compliance, a tungsten electrode of any type — pure, thoriated, ceriated, lanthanated, and others — is typically considered a non–essential variable, meaning that tungsten electrodes of different types can be introduced into the process without triggering the need to re qualify the process itself.

When a non–essential variable is changed, it should be documented by updating the Welding Procedure Specifications, but process requalification is not required for continued code compliance.

NOTE: It is the responsibility for every user of the various codes to review and confirm if changes in non–consumable tungsten electrodes, or changes of any other typically non–essential variable, could require requalification of the process.

W-E3 composite Tungsten Electrodes Similar Conductivity Compared to Thoriated Tungsten

W-E3 Tungsten Electrodes provide conductivity similar to that of thoriated electrodes. Typically, this means that E3 Tungsten Electrodes are exchangeable with thoriated electrodes without requiring significant welding process changes.

W-E3 Tungsten Electrodes are Individually Tested

Every electrode is tested for structural defects using an eddy current test method. This is your assurance that each and every electrode will perform well in the field.
