Under the premise of the shortage of welders in China and the need to reduce staff and increase efficiency, the practical application of H-beam robot welding faces many challenges.
H-beam steel has large size and weight, and it relies on heavy equipment (such as turning machine) for handling and positioning, which is easy to cause weld deviation due to clamping deviation.
Influence of heat input: continuous welding produces high thermal stress, resulting in flange and web Angle deformation, wave deformation, and quality is difficult to reach the standard.
Workpiece size error, group gap uneven influence penetration and appearance, process fluctuation, resulting in poor weld quality consistency.
H-beam steel involves multiple types of welds (fillet welding, vertical welding, tilting welding), traditional teaching programming is time-consuming and labor-intensive, path planning is difficult, and complex weld programming efficiency is low.
The robot system (body, position shifter, sensor) and supporting facilities have high initial investment cost and long return period.
Multiple specifications and small batches require frequent switching of production lines, long machine downtime, low utilization, and poor flexibility.
In cooperation with Minyue Technology, a head steel structure enterprise launched a reverse modeling intelligent welding scheme to solve the problem of complex workpiece welding in three steps, aiming at the cost reduction and efficiency improvement of I-beam welding.
Minyue technology adopts self-developed SmartVision-structured light vision system, advanced large-range linear laser 3D camera, high precision in single line direction, high laser brightness, strong anti-ambient light interference, and can be applied to various work scenes. Using 3D vision, advanced optical devices and AI imaging algorithms, it can generate high-quality 3D point cloud data for high-reflective welding-groove/multi-reflective welds/sheet lap welds common in welding scenes, and the scanning speed can reach 100mm/s. Fast reverse modeling can be achieved in 20 seconds.
RobotSmart- Intelligent decision system, intelligent extraction of welding seam with one click, automatic generation of welding trajectory and robot motion code. Using digital twin technology, robot motion simulation, collision detection, singular point avoidance and axis limit detection are realized. Using advanced algorithm, with welding expert process library, 30 seconds to complete the calculation.
SmartEye - laser weld tracking system, fast scanning weld, speed up to 200mm/s, real-time correction in the welding process, perfect welding, 2 minutes arc.
Welding speed 6.6mm/s,400mm/min, no programming, no teaching, one person can see 4 machines.
