Most of us have probably never given much thought to how two metal pieces bind together, but it is an essential part of most things around us. From cars to skyscrapers, the science of welding has an influence on how strong and durable these structures are. This is why welding technology continues to be one area where innovation thrives.
A bit of clever robot weld programming has come from local innovator, Andrew Turner, at NETPark – the science park just a few miles from Durham city. A former Senior Engineer for a major car parts manufacturer, Andrew drew from his own experience to solve a costly welding problem in automotive welding.
He essentially introduced laser light technology to enable the welding robot to be positioned with tremendous accuracy. The optimum torch position is reached when all four laser LEDs are combined to only a single focal point on the work-piece. If two or more points are visible the torch is either too close or too far away from the work-piece.
This results in shortening production times considerably, and offers savings during rework and quality control. This technology innovation has now been licensed to global welding equipment manufacturer Abicor Benzel in their Abidot product.
Andrew’s product design company continues to develop a pipeline of exciting products involving light technology, which we are looking forward to see in the near future.
The bright and always clearly visible laser point helps with the exact positioning of the welding spot in the often insufficiently illuminated working environment in a robot cell.
”It did not take me long to come up with this solution using laser light, and it is great having a global market player adopting the technology. What has also been really interesting while working on the Abidot product is the other applications I have found with laser light in a completely different sector. Watch this space!”
