The user friendly welding robot has taken over more than half of the man hours and has proven to provide high-quality work.** **![Lars Jakobsen fra Uniwelco (tv.) og Morten Bach Larsen fra Gromas (th.) foran svejserobotten RBCobot fra Uniwelco](https://www.uniwelco.com/hubfs/DSC_0263_jpg-jpg.jpeg)** "It's not possible" was what Morten Bach Larsen was told when he started to research the market for a more efficient solution for the welding work on rotors for water pumps. He ended up finding one and has now been reassured that this was the right decision. He is now reaping the benefits of the robotic arms controlled welding movements. **Better end products** It turns out that it *was* possible to meet the quality expectations of the welding seams at Gromas, that is a subcontractor of the food industry. The results were acutally better than the work done manually - they simply turned out more uniform and with fewer deviations from the desired end product. "Uniformity and the difficulty of handling the heat by hand, was something we were not able to compete with by manually welding" Morten says. When the robot has done its job, the welders are left with a better end product and less post-processing. This is especially true for the balancers previously added: Morten says: "We used to add 140 grams. Now, the worst ones only require 10-15 grams. The thin part of the axis, we need to be precise within 5 grams, and we normally don't see any deviations what so ever." ![Svejserobotten RBCobot der svejser en metal rotor til vandtank](https://www.uniwelco.com/hs-fs/hubfs/DSC_0243_jpg.jpg?width=1920&name=DSC_0243_jpg.jpg) **"It has freed up a lot of manual hours"** Apart from the unsatisfactory welding results, the robot was able to clearly deliver an improvement in workflow efficiency in terms of the items being weld. When the item is ready for the turntable, the welder is supposed to activate the pre-configured program, and then the robot will take care of the rest. Afterwards, a short amount of post-processing is required, but that has also considerably been reduced. The welding of all the seams on the pump takes exactly 52 minutes. Before the robot it took approximately 3 hours. The difference has many benefits, including to ensure the deliverabilty at Gromas: Morten elaborates: "The automation enables us to deliver all rotators we are supposed to. We were not able to before. Before we were able to deliver 550 finished rotators per year, now we are able to deliver 800." ![Lars fra Uniwelco snakker med Morten fra Gromas om svejserobotten RBCobot fra Uniwelco](https://www.uniwelco.com/hubfs/DSC_0267_jpg-jpg.jpeg) **Skilled professionals behind** The workers at Gromas has welcomed their new robotic coworker, which they have now had for 1,5 years: "It's been exciting to bring a robot in. It's nice to get new hardware, and some people have really been putting it to work." Morten says. He points out, that the skilled workers play a vital role in following up on the development, required by the customer: "The work put out by the robots will not be better than the input, "he says and further explains, that they have spend some time creating the right tempaltes for the welding of the pumps, which has further improved the end results. **Tags:** [Case](https://www.uniwelco.com/news/tag/case) ![Team Uniwelco](https://www.uniwelco.com/hs-fs/hubfs/Uniwelco%20logo%20sort%20(2)-Kittl%20(1)-1.png?width=120&height=120&name=Uniwelco%20logo%20sort%20(2)-Kittl%20(1)-1.png) Post by [Team Uniwelco](https://www.uniwelco.com/news/author/team-uniwelco) Mar 30, 2022, 10:46:02 AM ### Related Articles ##### [![Innovation in the Danish wind energy sector](https://www.uniwelco.com/hs-fs/hubfs/til%20cover%20artikel.png?width=520&height=294&name=til%20cover%20artikel.png) Case • Dec 20, 2022, 2:23:55 PM Innovation in the Danish wind energy sector 2 min read](https://www.uniwelco.com/news/windpower?hsLang=en) ##### [![CATEK successfully integrated welding robots, and reap the benefits](https://www.uniwelco.com/hs-fs/hubfs/2mdq9dm1jnzyqurb%20cropped.jpg?width=520&height=294&name=2mdq9dm1jnzyqurb%20cropped.jpg) Case • Jan 17, 2022, 11:41:16 AM CATEK successfully integrated welding robots, and reap the benefits 1 min read](https://www.uniwelco.com/news/catek-case?hsLang=en) [![Uniwleco Logo med Sort Tekst Nyt Logo (1)](https://www.uniwelco.com/hs-fs/hubfs/Uniwleco%20Logo%20med%20Sort%20Tekst%20Nyt%20Logo%20(1).png?width=200&height=58&name=Uniwleco%20Logo%20med%20Sort%20Tekst%20Nyt%20Logo%20(1).png)](https://www.uniwelco.com?hsLang=en) - [RBCobot Welder](https://www.uniwelco.com/en/what-is-rbcobot-welding-robot) - Add-ons & Software - [Training](https://www.uniwelco.com/en/training) - [Cases](https://www.uniwelco.com/news) - [About Uniwelco](https://www.uniwelco.com/en/about-uniwelco) ©2026 Uniwelco ApS.
