However, Pemamek will have special emphasis on two areas: its new laser scanning software for weldments and its dedicated expertise and technology for offshore wind manufacturing.
Named PEMA WeldControl 500, the new laser scanning software for weld seams “reads” the weld groove before the weld and after the weld from two separate angles. In this new laser scanning solution, essentially the operator of the automatic welding system sees a graphical representation of the weld groove geometry on a display screen at any given point in the seam. It can be conveyed in several different ways, such as a groove fill graph. It presents and saves every piece of data, including speeds, fill volumes, temperatures, amperages, and more.
The scanning process acquires and stores the geometric, speed, and fill data as the robot welder travels along the seam. Alarms are set to sound or message when the weld goes out of tolerance for any parameter ranges established in advance in the system. The welding operator can go back and resolve the issue and then let the customer know that a repair was made exactly where and when.
Another benefit with this new technology is having remote access to the welding data out in a wind farm or at the power plant or wherever the installation stands or floats. For example, the data can be stored securely in the cloud while the wind tower or ship hull in question has a QR code associated with it that can be scanned by a QR code reader on a smartphone and the specific data can be reviewed.
“Nowadays, it’s all about data,” said Michael Bell, director of sales–North America. “This technology not only provides data for each point along the groove, but it is accurate, reliable, and searchable data that is extremely helpful to our customers and their customers, all the way down through the supply chain.”
Pemamek will be ready at Fabtech 2021 to discuss many large welding applications in a variety of industries, but it will have a special focus on the offshore wind market. The company views this is a growing market and has developed several packaged solutions for the welding of wind tower production. Wind sector experts will be available to share best practices in automatic welding for wind towers and foundational structures.
