3d laser welding

What is 3D Laser Welding?

As economies and industrial landscapes continuously evolve towards advanced technologies, sectors like aviation, high-speed rail, automotive, and renewable energy have been experiencing exponential growth, driving an escalating demand for highly efficient, precise, and eco-friendly manufacturing processes. In these progressive industries, there is a pressing need to tackle the complexities inherent in large size sheet metal components featuring intricate profiles, curved surfaces, and challenging materials that are difficult to manipulate using conventional methods. It is against this backdrop that the advent of 3D automatic laser welding has emerged as a pivotal solution, tailor-made to address these sector-specific requirements.

3D laser welding is a precise welding process that uses a laser beam to weld workpieces in three-dimensional space. Compared to traditional flat laser welding, 3d laser welding machine fills the gap in high-tech industries for high-quality welding of complex structures and special materials with its advantages of high efficiency and precision. 3d robotic laser welding integrates high-performance laser welding system, flexible robotic arms, precise three-dimensional scanning technology, and intelligent control systems to achieve three-dimensional welding of metal components of various shapes and thicknesses.

In three-dimensional laser welding, the laser beam is focused to create a high-energy density heat source on the surface of the workpiece, causing localized melting and fusion with other workpiece components. By controlling the movement trajectory and focal point position of the laser beam, precise welding can be achieved in three-dimensional space.

3D laser welding systems are capable of handling complex production processing requirements, providing high-speed operation, high precision, and high-quality results to meet the needs of various industries such as sheet metal processing plants, hardware processing, kitchenware, automobiles, electronic devices, artworks, small toys, lighting fixtures, woodworking saw blades, electrical equipment high-voltage switch cabinets, various metal products, textile equipment, grain and oil machinery, eyeglass frame manufacturing, and instrument equipment.

Advantages of 3D Laser Welding

By integrating a high-power and stable laser generating device, precise control and efficient energy utilization are ensured during welding, facilitating fast and uniform melting of different metal parts. Moreover, the flexible six-axis robotic arm system allows real-time adjustment of laser beam position and angle in three-dimensional space, effectively handling welding challenges on complex curved surfaces and deep cavity structures. Advanced intelligent control algorithms enable accurate tracking and adaptation to workpiece geometry changes, ensuring weld seam consistency and integrity.

Multi-angle Welding: Laser welding robots can achieve multi-angle welding for complex workpieces. Before starting work, programming is required, including setting parameters such as the swing range, type, and frequency of the welding torch. Through real-time interfaces, laser welding robots can be connected to scanner optical configurations, controls, and optical sensors, enabling application in more complex scenarios.

Enhanced Production Efficiency: Traditional welding is affected by welding environment and human factors, slowing down the process and hindering proper production planning. High levels of automation in Lush Smart Welding Robots allow for continuous operation and long welding tasks, thereby boosting production efficiency.

Superior Welding Results: 3D laser welding is up to 10 times faster than traditional MIG welding and 40 times faster than traditional TIG welding, reducing labor costs. It can manufacture higher-quality products at lower costs, with lower electricity consumption and consumables usage, ensuring stable welding quality.

High Precision: Laser welding is inherently more precise than traditional welding. When combined with advanced 3D vision systems, welding precision can exponentially increase even for large-scale and multi-pass parts.

Reduced Labor Costs: Welding robots equipped with auxiliary equipment can automatically flip plate elements and perform repetitive production tasks, reducing labor costs.

Compared to traditional 2D laser welding, although 3D laser welding may be slightly less accurate in absolute terms, it is able to overcome complex 3D geometries that cannot be handled by 2D welding, and is particularly suited to applications that require refined, distortion-free welding. 3D laser welding technology controls the manipulator’s path of action through pre-programmed 3D routines and supports independent offline programming and virtual simulation, allowing engineers to visually preview and optimize weld paths before they are actually operated.
