Welding workshops operated by SME companies are a basic unit of industrial manufacturing. Economic pressures are forcing these firms to find solutions for wasteful and time consuming tasks, like creation of custom clamping assemblies for each set of pieces to be welded. The design and fabrication of the clamping assembly itself involves time and costs both for design and fabrication. These clamping assemblies cannot be adapted to other production tasks, and become waste themselves.The recent assembly processes are CAD file driven, including welding processes as well. In this case the envisioned solution consists of an innovative software that can be optionally linked to existing hardware components.The software component of CLAMPIT can analyse any given option saved in the CAD file in order to determine the best conditions (e.g.: clamping angles/forces/etc., the required setup elements for clamping, the appropriate points for clamping the assembly pieces, the layout for optimised part distribution on the work-bench, the proper part order of the welding, the directions of optimised welding trajectories, etc...) to complete the welding process. Namely any task on the welding-table is driven by the processed orders of the software component what are partial utilised by the hardware components and partial should be setup according the orders handcrafted by the skilled workers.The software will give important information to the user on its own, but it can also be linked to any existing versatile clamping table on the market allowing the user to determine measurable fixing positions of the items intended to be welded.
