using Lasers in welding
and materials joining

EWI has been instrumental in furthering laser technology in a variety of industries. Using state-of-the-art laser processing equipment, our highly-trained staff help Members through development of welding, cutting, surface treatment and overlay procedures, laser beam analysis, in-plant assessments, process evaluations, and limited production runs.

Laser Technical Advisory Committee (LTAC)
Because EWI is committed to staying at the forefront of Laser technology, we formed the Laser Technical Advisory Committee (LTAC), which is comprised of representatives from EWI Member companies involved with laser materials processing. The goal of the committee is to identify central and common technical issues associated with laser materials processing and to guide EWI resources to make sure that these needs are met. LTAC also promotes networking of EWI Member companies with common laser processing interests. We invite you to visit LTAC Web Site.

Laser Basics
Lasers produce monochromatic and coherent beams of light that can be focused to spot sizes less than .030-inch in diameter. This results in power densities far greater than other traditional welding processes. The small spot size and high power density result in the following advantages:

• Ability to weld smaller, thinner components
• Deep, narrow welds in thick materials
• Increased travel speeds
• Non-contact welding
• Lower overall heat input resulting in minimal distortion, minimal degradation of material properties, and reduced thermal damage to nearby sensitive components.
