Laser welding utilizes high-energy laser pulses to locally heat a minute area of the material; the energy from the laser radiation diffuses into the material's interior via heat conduction, melting the material to form a specific molten pool. It is a modern welding method primarily designed for thin-walled materials and precision components, capable of performing spot welding, butt welding, lap welding, and seal welding. Key advantages include a high depth-to-width ratio, narrow weld seams, minimal heat-affected zones and deformation, high welding speeds, and smooth, aesthetically pleasing welds. The process yields high-quality, porosity-free welds that require little to no post-processing. It offers precise control, a small focal spot, and high positioning accuracy, making automation easily achievable.
