APPLICATION INFORMATION
SEISMIC STRUCTURAL WELDING APPLICATIONS
The electrodes below have been tested in accordance with FEMA
353 - Recommended Specifications and Quality Assurance
Guidelines for Steel Moment-Frame Construction for Seismic
Applications. FEMA 353 test certificates are available upon
request. These certificates contain mechanical test results at low
and high heat input levels and diffusible hydrogen classifications.
The electrodes indicated with a * also have electrode exposure
time on the certificate.
ELECTRODE EXPOSURE
FEMA 353 and other specifications which limit electrode exposure
may require monitoring electrode exposure time and/or conditions
after removal from a sealed package.
