When Universal Robots (UR) introduced North America’s first cobot welder at FABTECH 2017, it marked the beginning of a revolution in automation. Fast forward to today, and cobot welding has evolved at lightning speed, bridging the gap between traditional automation and collaborative robotics. From MIG to TIG, and even laser and spot welding, cobots are taking on more complex tasks than ever before. Let’s dive into the exciting world of cobot welding and explore how these innovations are transforming industries.
Back in the day, UR cobots were primarily used for air-cooled MIG welding solutions placed on carts. However, the game has changed dramatically. According to Will Healy III, global industry leader of welding at Universal Robots, cobots are now engaging in heavy-duty tasks like TIG, laser, and spot welding, and even plasma- and oxyfuel cutting. This leap in capabilities means that industries can now rely on cobots for tasks that were once too complex or labor-intensive.
At Universal Robots’ FABTECH booth, visitors can witness cobots “going beyond the cart,” with expanded work envelopes and dual-axis welding capabilities. The introduction of UR’s new MotionPlus package allows for coordinated motion, enabling cobots to sync with rotary positioners or linear rails. This advancement allows for seamless welding of parts without manual intervention, paving the way for more efficient and precise operations.
This year’s FABTECH saw a groundbreaking development in cobot welding with the introduction of UR’s MotionPlus package. For the first time in North America, multi-axis cobot welding with coordinated motion was showcased. This innovation is not just a technological marvel but a practical solution for tackling complex, multi-faceted parts in welding applications.
Vectis Automation, one of UR’s pioneering partners, launched the RevoTM Dual Axis system, which excels in positioning parts relative to gravity. Coupled with features like QuickTeach and AI Path Optimization, Vectis is setting new standards in cobot welding. QuickTeach allows users to teach weld points directly at the torch, while AI Path Optimization ensures welds meet procedure specifications with precision.
One of the most exciting developments in cobot welding is their newfound mobility. Gone are the days when cobots were confined to stationary positions. With innovations like the Inrotech-Crawler and Hyundai Welding’s portable cobot system, these robots are breaking free from traditional constraints and entering new production environments.
The Inrotech-Crawler, featuring UR’s smallest UR3 cobot, specializes in butt-weld connections and multi-pass welding. Its flexible rail system allows it to adjust welding parameters dynamically, making it ideal for complex welding tasks like those found in shipbuilding. Similarly, Hyundai Welding’s system addresses the tight confines of ship hull welding sections, providing an agile and efficient solution.
Welding is just one of the many tasks that cobots are mastering. At FABTECH, cobots were also showcased in press brake tending, finishing, and laser restoration. Mid Atlantic Machinery’s AutoTend system, featuring a UR10e cobot, demonstrated its ability to bend complex parts while interacting with press brake controls. Meanwhile, Cohesive Robotics’ Smart Finishing Workcell highlighted the potential of cobots in automated surface finishing tasks.
Advanced Laser Restoration showcased the seamless integration of laser cleaning technology with cobots, automating surface preparation tasks with pinpoint accuracy. These innovations not only enhance productivity but also open up new avenues for industries to explore automation in various applications.
In conclusion, the advancements in cobot welding and their expanding capabilities are revolutionizing industries. From complex welding tasks to portable solutions and beyond, cobots are proving to be invaluable tools in modern manufacturing. As we look to the future, the possibilities for cobot applications are endless, promising a brighter, more efficient tomorrow for industries worldwide.
