Pemamek introduces its PEMA Nozzle Welding Solution for pressure vessels and other heavy-duty welding applications. By automating the nozzle welding operation, man-hours required for multi-layer welding processes and defects are dramatically reduced.
Built-in lasers scan groove geometry in the workpieces, which typically contain largely 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 user-friendly WeldControl software family, which helps streamline the communication between the operator and machinery during welding operations.
“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,” said Michael Bell, Sales Director, North America.
The entire PEMA Nozzle Welding Station can accommodate workpieces measuring 500mm to 2000mm in diameter.
“ Any discrepancies between the pre-programmed groove geometry and the actual laser-scanned geometry are adjusted using the user-friendly WeldControl software family.“
“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 dramatic reduction in errors and defects is proof enough that this technology works.”
The entire PEMA Nozzle Welding Station can accommodate workpieces measuring 500mm to 2000mm in diameter, up to 6000mm in length, 100mm to 1000mmm nozzle diameter (30mm without scan function and depending on vessel radius), and 300mm distance between nozzles, and a weight of 15 tons.
