In the transformation of manufacturing toward intelligence and automation, traditional welding methods are gradually unable to meet the demands of high-precision welding tasks. This is especially true in exquisite steel welding, where requirements for weld quality are far more stringent. Conventional methods that rely on manual experience or fixed programming often struggle to achieve stable and consistent results under complex conditions. To address this, the Weld Navigator® laser seam tracking sensor provides a brand-new intelligent solution for exquisite steel welding.
Principle of Laser Seam Tracking
The Weld Navigator® laser seam tracking sensor projects laser beams and uses high-precision imaging to capture the dynamic changes of weld position and the molten pool in real time. Based on advanced algorithms, the system quickly identifies weld features, calculates them, and extracts three-dimensional data such as weld center, width, depth, and groove shape. It then outputs deviation information to the Chaifu welding robot, enabling automatic path correction. This effectively avoids common problems such as weld deviation and torch misalignment, ensuring a precise and stable welding process.
Challenges of Exquisite Steel Welding
Exquisite steel, as a high-quality structural material, offers advantages such as high strength and low deformation. It is widely used in high-end equipment, precision instruments, and architectural curtain walls. However, its welding poses unique challenges:
-
Strict assembly precision: Gaps and misalignment during part assembly must be controlled within very small tolerances, as even minor deviations can lead to burn-through, incomplete penetration, or poor weld formation.
-
Thermal deformation: Small deviations may cause material distortion, rendering pre-set welding paths invalid.
-
Surface reflectivity: Conventional vision systems often struggle to accurately detect weld positions due to reflective surfaces.
-
Dependence on skilled workers: Welding adjustments often rely heavily on experienced welders, which lowers productivity.
Weld Navigator® Solution
To tackle these challenges, Weld Navigator® has developed a comprehensive intelligent welding solution in collaboration with Chaifu robots:
-
Real-time tracking: Dynamically captures the weld path during welding and automatically adjusts the trajectory to compensate for assembly errors and thermal deformation, achieving truly adaptive welding.
-
High precision performance: Maintains stable detection even under reflective or narrow-gap conditions.
-
Improved consistency: Reduces reliance on operator skill differences, ensuring stable weld quality.
-
Cost reduction: Minimizes rework rates, enhances production efficiency, and helps enterprises reduce costs while improving performance.
Application Case
In practice, the Weld Navigator® laser seam tracking sensor has been successfully integrated with Chaifu robots in the welding of exquisite steel components for a high-end equipment manufacturer. Before seam tracking was installed, the robot torch frequently deviated from the weld, causing welding failures. After activating the laser seam tracking system, the Chaifu robot was able to dynamically adjust its welding path, precisely follow the misaligned welds, and complete smooth, uniform welds.
As manufacturing continues to pursue higher quality and efficiency, intelligent welding has become an inevitable trend for industrial upgrading. The Weld Navigator® laser seam tracking sensor is compatible with more than 40 robot brands and specialized welding machines, providing enterprises with highly efficient and reliable welding solutions. Looking ahead, Weld Navigator® will continue driving advancements in welding automation technology and support more industries in achieving smart manufacturing transformation.
