What Is A Keyhole In Laser Welding
A keyhole in laser welding is a vapor-filled cavity created when a high-energy laser beam melts and vaporizes material. This process enables deep penetration and efficient energy absorption, making it essential for high-strength and precision welding applications. In this guide, we explain how keyholes form, why they matter, key factors affecting stability, common welding defects, and the differences between keyhole and conduction welding.
