Galvo laser welding is a process that harnesses the energy of a high-power laser beam to directly melt-weld the surface of a workpiece. The laser beam is initially focused onto the reflector mirror, and through the control of the galvanometer, the position of the focus is manipulated. This ensures that the laser energy is accurately directed onto the surface of the workpiece during welding. The high-energy laser beam swiftly heats the metal material on the workpiece surface, causing it to melt rapidly and form a weld seam. Throughout this process, the angles and positions of the laser galvanometer continuously change, enabling continuous, seamless welding of the seam while avoiding issues such as deformation and residual stress.
Galvo laser welding comprises three main components: the optical system, laser source, and control system. During operation, the laser beam energy is generated by the laser source and is precisely aligned and focused onto the reflector mirror through the optical system. The galvanometer control system then regulates the position and angle changes of the focus, facilitating the welding process on the surface of the workpiece.
Galvo laser welding is characterized by its simplicity of operation, high-quality weld seams, and precision. These attributes make it widely applicable in critical fields such as automotive, aerospace, and robotics.
In industrial production, galvo laser welding technology finds extensive applications in welding various materials, including metals, plastics, ceramics, and more. When compared to traditional welding methods, galvo laser welding presents several notable advantages:
High-Quality Weld Seams: The precise control of welding power and time in galvo laser welding results in fine, stable, and high-quality welding outcomes.
High Welding Speed: Galvo laser welding allows for high-speed, continuous welding, significantly enhancing production efficiency and speed.
Ease of Operation: The simplicity and convenience of operation and maintenance make galvo laser welding more user-friendly than traditional welding methods.
Minimal Impact on Materials: The concentrated heat generated during the welding process affects only the welding interface, leaving the rest of the welded material unaffected.
As laser technology continues to evolve, so does the refinement and improvement of galvo laser welding techniques. Presently, galvo laser welding has become an integral part of the manufacturing industry, particularly in sectors like automotive, aerospace, and electronics, where its applications continue to expand. The future trends in galvo laser welding development focus on further enhancing welding quality and speed to enable even broader applications across various industries.
