Laser welding is one of the earliest popular laser industrial applications. Many important laser application companies at home and abroad started from laser welding. Even now, laser welding technology has become a standard process in many industries, such as automotive, aviation, and power batteries that have emerged in recent years.
No matter what kind of laser source is used, the purpose of welding is to heat and melt two pieces of material, which may be the same material or different materials, and then re-condensate into one piece of material.
