www.lincolnelectric.com
Introduction
Lincoln Electric, the worldwide leader in welding
equipment and consumables, is proud to present
this manual to the American Welding Society’s
D1.8 Seismic Supplement.
Because welding is essential in the construction of
the vast majority of buildings, innovative welding
techniques are and will continue to be critical to
safer, sounder structures in seismic zones.
The leader in seismic welding solutions is
Lincoln Electric.
Our leadership comes from our history; for over
100 years Lincoln Electric has been at the forefront
of welding technology. It comes from our people;
Duane Miller, Lincoln’s Manager of Engineering
Services, chaired the D1.8 committee. And it comes
from our products; we have consumables and
welding solutions designed help you meet new
and evolving requirements.
To assist structural fabricators, erectors, inspectors
and specifying engineers, Lincoln Electric has
created this D1.8 Seismic Supplement Welding
Manual as an aid to understand seismic welding
requirements and the Lincoln Electric consumables
tested to meet the AWS D1.8 requirements.
This update to Lincoln Electric’s D1.8 Seismic
Supplement Welding Manual is just one more way
Lincoln sets the standard for the welding industry.
That is why, for the most reliable welds in seismic
zones, the structural fabrication industry chooses
Lincoln.
