Learn, Network & Explore the Possibilities

By Betsy Marone

In its fifth year, Laser Institute of America’s Lasers for Manufacturing Event® (LME®) will continue its tradition of offering attendees a unique and comprehensive two-day look into the laser industry. Taking place at the Cobb Galleria Centre in Atlanta, GA, April 26-27, LME will serve as a one-stop shop for companies looking to integrate laser technology into their production. Since its inception, LME has filled a void in the laser industry by providing one event where attendees can see the latest advances in laser technology, network with elite members of the laser industry, discover solutions to both current and future manufacturing needs, and gain a better understanding of laser basics in free education sessions.

Orlando, FL (Sept. 17, 2014) – Presenting first in what will be a two-day education track, David Havrilla will lead a tutorial on Principles of High Power Laser Welding on Tuesday, Sept. 23, the first day of the Laser Institute of America’s fourth annual Lasers for Manufacturing Event® (LME®), in Schaumburg, IL.

Havrilla is the manager of products and applications for TRUMPF Inc.’s laser division and brings with him 23 years of industry knowledge and acumen.

TRUMPF is a worldwide conglomerate widely considered to be one of the eminent names in laser design and components,  with Havrilla representing their wealth of experience in manufacturing in his tutorial presentation.

Laser welding has revolutionized the manufacturing and machining world. Allowing metals previously thought impossible to weld to be joined, laser welding has taken the automotive, medical and aerospace component manufacturing industries into new territory. The focused and precise nature of laser welding has led to breakthroughs in design, stability and aesthetics in the markets taking advantage of this technology.

While glass is widely used in different industrial field due to its excellent physical and chemical properties, there exist no reliable joining procedures of glass at the moment. We have developed a novel fusion welding procedure of glass that can weld glass even with high coefficient of thermal expansion (CTE) using ultrashort laser pulse (USLP).

Recently, ultrashort laser pulse (USLP) has brought a new wave of laser welding that enables crack-free welding of dielectric material like glass without pre- and post-heating. The advantages of USLP welding of glass are provided by embedded molten pool due to the unique laser absorption mechanism of nonlinear process. It has been shown that the stress due to the thermal shrinkage of the weld bead can be in principle prevented in USLP welding of glass where molten pool is embedded in bulk glass. The embedded molten pool also provides advantage of local melting selectively only at the joint interface. Continue reading →

Production of High-Quality Welds Using Hybrid Laser/GMAW on Thick Steel

In the last years, several groups have worked on the development of hybrid laser/GMAW welding (HLAW), for various segments of the industry.  Depending on the intended application, the objectives are significantly different, and the definition of quality itself can differ a lot.  Nevertheless, new HLAW applications usually benefit from the ability of the process to produce deep welds in one pass without having to chamfer the parts.  As shown on Figure 1, the HLAW welds are drastically smaller than GMAW welds, going from several passes (six on the picture on the left) with chamfer and back gouging to a single pass without chamfer.
