CORE DIFFERENCE BETWEEN A LASER BEAM WELDER AND A TRADITIONAL WELDING TECHNIQUE IN TERMS OF THE PHYSICAL PRINCIPLES INVOLVED, AND HOW DO THE LASER'S CHARACTERISTICS INFLUENCE THE WELDING PROCESS

A laser beam welder (LBW) employs highly concentrated light energy to achieve a precise, localized heat source, allowing it to fuse materials together. Unlike traditional welding techniques, which typically rely on mechanical or chemical heat generation from sources such as an electric arc, gas flames, or a heated electrode, laser welding works on
