The Pema nozzle-welding system from Pemamek Oy is designed for automatic welding of pressure vessels and other heavy-duty welding applications. Built-in lasers scan groove geometry in the workpieces, which typically contain large prepared grooves and thick plates, and automatically create robotic welding programs that adapt to the varying groove layers by continuously welding the grooves until a solid bond is formed. Any discrepancies between the pre-programmed groove geometry and the actual laser-scanned geometry are adjusted using the WeldControl software, which helps to streamline the communication between the operator and machinery during welding operations. Production data monitoring, diagnostics, tracking, and robot programming can be performed by one operator on a one-panel control system on the shop floor.
“This nozzle welding solution can shave hours off of the amount of time it would typically take to perform multi-pass welding operations in thick-walled workpieces with irregular grooves,” says Michael Bell, sales director. “By combining the accuracy of laser scanning and the seamless transfer of the resulting scan data to the WeldControl software to generate a program specific to that application, robots can more quickly and accurately perform the multi-layer welding passes while the operator moves on to the next project.”
The Pema nozzle welding station can accommodate 15-ton workpieces measuring 500 to 2,000 mm in diameter, up to 6,000 mm in length, 100 to 1,000 mm nozzle diameter (30 mm without scan function and depending on vessel radius), and 300 mm distance between nozzles.
