Individual particle characterization device for cold spray processes
The Rotoweld 3.0 twin configurations include two separate work bays and rotators to maximize the work cell’s throughput by allowing one work bay to be re-loaded while welding in the alternate one. The motorized welding carriage travels between work bays along a continuous track system, which also guides the idler rolls to maintain perfect alignment along the full length of the machine.

"We’ve had Rotowelds in our Lebanon plant for over 15 years…These machines quickly became a vital part of our production operations…Through the years, the Tecnar team delivered excellent response, service and parts delivery and replacement…We purchased Tecnar’s latest Rotoweld model, the 3.0. It is a giant leap forward for technical advancement, functionality, performance and up-time. It’s been running for over a year now—absolutely trouble-free. Everything was re-engineered, streamlined and, unlike some of the newer technologies, technically intuitive…The new robot manipulator, standard Siemens controls and “off-the-shelf” hardware place the Tecnar Rotoweld exponentially ahead of all their competitors. Tecnar is more than a quality vendor and supplier—they are a direct part of our Perma-Pipe team!"
