Although most tube and pipe producers don't get too involved in the regrind process, it is crucial—reconditioning roll tooling can extend its useful life by 15 or 20 times. The regrind process reduces the producer's overall out-of-pocket tooling expenses, while helping to ensure the tooling continues to produce a consistent-quality product at the required speeds. A better understanding of the process, especially familiarity with the types of flaws that reconditioning can and cannot resolve, can go a long way toward a better working relationship between a tube and pipe producer and its regrind contractor.

Planning a productive intelligent robotic welding workcell requires many phases. These include preplanning with a computer simulation, getting the virtual results to translate into real-world operation, using multiple robots within the workcell for material handling as well as welding, and utilizing vision systems to help compensate for part variations.
