Laser welding has quite different challenges from electrical welding as the heat-affected zone is so much smaller, much less energy is delivered to the metal to perform the weld. I'd like to read more about the research in the article to see what they've done to address this or if it was even an issue for them! It probably depends on the thickness and orientation of the metal and fixturing.
