NIST Study Will Help Industry Understand and Use Laser Welding
GAITHERSBURG, Md., May 2, 2019 — A better understanding of the interaction between laser and metal could give industry more control over laser welding, according to a three-year study in laser welding conducted by the National Institute of Standards and Technology (NIST). The data that NIST scientists collected is being used by computer modelers to improve simulations of laser welding processes, a step toward applying the findings to industry. The goal of the NIST team is to build a firm foundation for a model for laser
