3D Profiling is an automated process of cutting 3-dimensional forms on metal pipes, beams and other profiles. These cuts prepare the profiles for the purpose of forming welded connections. While 2D profiling is where flat bars or plates are cut, 3D Profiling is the cutting of 3-dimensional forms on non-flat material, thus forming a precise geometrical fit in order to create strong welded connections.
3D Profiling is performed by means of a CAD-CAM (computer-aided design & computer-aided manufacturing) connection and a CNC cutting machine. Extra welding specifications can also be included into the dimensions of the cut, such as shrinkage, groove angle and root opening.
3D profiling is performed by a plasma or oxyfuel cutting torch mounted on a robotic arm. This profiling process also compensates for distortions in the material, such as curved beams or distorted pipes. This is done by a combination of laser measurement systems and clever mechanical engineering.
Thanks to the weld preparation applied during the design & detailing stage, the parts are ready for optimized fitting and welding immediately after profiling. Parts fit easily and weld volume is greatly reduced, which results in significant savings in time and costs.
