Smart robot that determines its own welding path
Instead of learning each welding point individually, all the operator has to do is bring the robot to its starting position. The rest is done by the technology.

Smart robot that determines its own welding path

At the upcoming edition of Schweissen & Schneiden, the world's leading trade fair for joining, cutting and surface technology, TRUMPF will show a robot that uses sensors to program its own weld path. To do so, the robot relies on TRUMPF's new smart weld path tracking technology, Smart Seam Tracking. The high-tech machine manufacturer from Ditzingen developed it in close cooperation with the Fraunhofer Institute for Manufacturing, Engineering & Automation IPA. "Basically, we developed a way for the robot to program itself," summarizes TRUMPF R&D manager Sven Klingschat. From the head of the welding torch, the sensor automatically calculates the welding path for each part.

With Smart Seam Tracking from TRUMPF, the robot calculates its own weld path.

With traditional welding robots, operators must program each new weld point into the software if they want to make the robot change direction. A process that is extremely time-consuming, especially when it involves complex pieces with many turns and angles. Fortunately, the new weld seam tracking system Smart Seam Tracking makes this process a whole lot easier. All the user has to do is place the welding robot in the start position. The technology then does the rest. Using the sensor, the robot automatically plots its welding path. In no time, the system software calculates the welding points and generates a welding program for the piece in question. In a few seconds, the robot is ready to begin its job. A solution that makes it much easier to program the robot. 

"The process still only takes seconds, even for complex pieces like spiral arcs. And it doesn't require a rocket scientist at the controls," Klingschat assures. Even more, thanks to the intuitive user interface, many welding tasks can be performed, such as sealing or laying identical welds.

Simple programming
The welding robot can be programmed within seconds, even for complex pieces. This unburdens employees and helps companies address the shortage of technically skilled workers.

Less waste and a more stable process

Smart Seam Tracking helps companies save time and costs, while making the work of operators on the production floor much easier. The robot's ability to automatically adjust its weld path makes the entire process much more stable. It also further simplifies dealing with the tightest tolerances and warping or deformation. This is the right solution for any company looking at automation to increase productivity. It is particularly suitable for manufacturing companies that weld large and complex pieces. Creating an individualized weld path for each individual piece is an excellent way to deliver consistently high quality. Components for wind turbines or screw compressors for the animal feed industry are just two examples of components that can benefit from this innovative and efficient method. TRUMPF will integrate the solution into its TruArc Weld 100 welding arc machines. They can also be retrofitted into existing TruArc Weld systems.
