Laser welding is used to join thin metal parts. At high speeds, it can leave bumps on the surface of the metal that make the weld weaker. Scientists used a powerful X-ray camera to take images during the welding process, which revealed key causes of the bumps forming. X-rays Reveal Why High-Speed Welding Goes Wrong
