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.
