As industries such as steel structures, shipbuilding, and construction machinery accelerate their digital transformation, more manufacturers are adopting robotic welding to boost productivity, reduce costs, and improve weld quality. Given the customized, small-batch, and multi-variety nature of welding tasks in these fields, demand for intelligent collaborative welding robots is surging.
ROKAE has been actively advancing robotic welding technology, drawing on its extensive portfolio of collaborative welding solutions, robust performance, and versatile features. With successful applications in steel structures, shipbuilding, and other industries, ROKAE has accumulated a wealth of practical experience.
Next-Generation Collaborative Welding Robots
ROKAE has launched its new generation of force-controlled collaborative welding robots, including SR3-C, SR5-C, CR7-C, and CR12-C models. Equipped with high-precision torque sensors in every joint, the robots achieve 10kHz real-time force control and enable ultra-sensitive drag teaching with as little as 1N of force.
With proprietary high-order dynamics algorithms, ROKAE robots deliver advanced vibration suppression and high-precision trajectory planning. A newly developed graphic programming system makes welding setup intuitive and user-friendly, offering a smarter welding experience beyond conventional collaborative robots.
Key Product Advantages
· More Precise：TrueMotion path planning and full-parameter compensation ensure linear trajectory accuracy within 0.5 mm and torch orientation error under 0.8 mm, meeting industrial-grade welding standards.
· More Stable: OptiMotion motion control and global vibration suppression deliver smooth, high-speed motion without torch oscillation, while robust hardware ensures durability even in demanding conditions. At the same time, it adopts motion planning based on dynamic constraints to ensure that the robot is stable and durable. Equipped with an IP54 high protection control cabinet that has been tested at a high temperature of 55 ℃, it is perfectly capable of working under demanding conditions.
· More Compliance: Full-joint force control allows natural drag teaching, improving programming efficiency by 20%.
· Safer: Ultra-sensitive collision detection based on full-joint force control, delivering 5 times higher sensitivity than traditional current-loop-based collaborative robots; an independently certified SIL3-rated RSC safety controller that monitors component status in real time; and a magnetic brake with a braking distance of less than 1 mm (vs. 10 mm for pin-type brakes), ensuring no drop during unexpected power outages for greater safety.
Smarter Welding Systems
ROKAE has also enhanced software intelligence to make robotic welding easier and more accessible:
· Graphical programming enables non-experts to master welding setup within minutes.
· An embedded welding expert database allows optimal parameter recall in 5 seconds.
· Adaptive groove welding automatically adjusts and optimizes paths.
· Weld bead fine-tuning offers precision control over interlayers and interpass gaps.
· Multiple weaving modes (e.g., bow, zigzag, triangular) support diverse applications.
· Smart arc-resume remembers seam positions, enabling seamless restarts after interruptions.
By combining precision, stability, compliance, and intelligence, ROKAE’s collaborative welding robots significantly improve welding efficiency and quality while reducing worker exposure to harsh environments.
Looking ahead, ROKAE will continue to enhance product performance and optimize welding systems to deliver intelligent, stable, and reliable automation solutions across even more welding scenarios.
