Introduced in the 1960s, laser joining technology is commercially underutilized due limited understanding of complex laser-matter interactions. The National Institute of Standards and Technology (NIST) has undertaken an effort to augment and elucidate laser-material interactions to benefit the advanced laser manufacturing environment. The following presents methodology for developing “smarter” welding technology by combining in-situ metrology, advanced materials characterization, mechanical properties assessment, and dynamic thermophysical properties data analysis. Initial results are presented for fiber laser welding of low- and medium-carbon sheet steels for automotive applications including parameter development, profilometry, microstructural characterization, and mechanical properties assessment.
