Additive Manufacturing (Page 12)

Every year at FABTECH, the AWS Professional Program offers a full lineup of educational sessions led by industry experts on new developments and best practices in welding. This year, EWI is pleased to present eight technical talks in the program: Evolution of Analytical Modeling Approaches for Resistance Spot Welding: A Historical Perspective — Jerry Gould, Senior...

Errors that occur during large-scale additive manufacturing (AM) builds can be prohibitively expensive for manufacturers. Current in-line inspection methods are inefficient, but damaged and distorted end products waste too much time, material, and money. How can in-process inspection be optimized to improve productivity and ensure quality? EWI investigated this question using the laser-blown powder DED...

Laser powder bed fusion is being used with increasing frequency in manufacturing operations. Some L-PBF materials, however, are still prone to stress and cracking. EWI has created a new “laser stirring” technique that improves results in some of the most common L-PBF alloys including SS316L, Ti-6Al-4V, and Ni718. The results are discussed in Effect of...
