Research sparks new insights on laser welding

On its surface, the work is deceptively simple: Shoot a high-power laser beam onto a piece of metal for a fraction of a second and see what happens. But researchers say the physics of laser welding is surprisingly complex. A better understanding of the interaction between laser and metal could give industry more control over laser welding, a technology that is becoming increasingly popular in manufacturing.

For the past three years, scientists at the National Institute of Standards and Technology (NIST) have been collecting data on the most fundamental aspects of laserwelding. The scope of their study is narrow, but the measurements of this complicated process are more accurate and comprehensive than any data ever collected on the subject, the researchers say.

Now, this information is starting to be used by computer modelers to improve simulations of laser welding processes, a necessary step to prepare the work for industry.

"Our results are now mature enough to where academic researchers are starting to use our data to thoroughly test their computer models in a way that they just haven't been able to do before, because this kind of data hasn't been available," said NIST physicist Brian Simonds.

Researchers run first tests of unique system for welding highly irradiated metal alloys

Scientists of the Department of Energy's Light Water Reactor Sustainability Program (LWRS) and partners from the Electric Power Research Institute (EPRI) have conducted the first weld tests to repair highly irradiated materials at DOE's Oak Ridge National Laboratory.

The welding system, designed and installed in a hot cell at ORNL's Radiochemical Engineering Development Center, safely encloses equipment for laser and friction-stir welding. It will allow researchers to advance welding technologies for repair of irradiated materials by developing processing conditions and evaluating post-weld materials properties.

As nuclear power plants age, materials that have been irradiated for several decades might require repair or replacement. Advanced welding techniques will be needed during the extended operational lives of America's nuclear power plants; construction on most began in the 1970s. These plants generate approximately 20 percent of the nation's electricity.

"Demonstration of advanced techniques for irradiated materials is a key step in validating weld repair as one mitigation strategy for extending the life of components and reducing costs for the nuclear industry," said ORNL's Keith Leonard, who leads research in the Materials Aging and Degradation Pathway for LWRS.

Novel technique expands industrial use of advanced high-strength steel alloys

The automotive industry's demand for high-performance alloys known as advanced high-strength (AHS) steels has increased in recent years owing to increasingly tough passenger safety, vehicle performance and fuel economy requirements.

Characterized by improved formability and collision resilience compared to conventional steel grades, high-strength steels have been used in critical safety locations in car body structures to absorb energy from impacts. However, some of these high-strength alloys tend to become brittle as a result of welding and may break when submitted to the hot stamping and forming required by many manufacturing processes.

"This problem makes it impossible to use AHS steel not only in the automotive industry but also in other industries such as aerospace," said Milton Sergio Fernandes de Lima, a researcher at the Brazilian Air Force Command's Institute for Advanced Studies (IEAv). To address this issue, Lima has developed an innovative method of high-temperature laser welding for AHS steel appropriate for aerospace applications.

The results, obtained while Lima was a visiting fellow at the Colorado School of Mines in the United States with support from the Sao Paulo Research Foundation, have now been published in the Welding Journal.
