Optimization of Gap Bridging Performance in Laser Butt Welding Using Beam Shaping Technology: Exploring the Application of Beam Shaping in Mass-Production [PDF]

Autogenous laser butt welding is widely used for its high precision, low heat input, and efficiency. However, variations in joint gaps can degrade weld quality. The conventional solution—using high-precision fixtures—is costly, time-consuming, and limits
