When manufacturing wind towers, it is often diffi cult to measure accurately the flatness or quality of a flange. Achieving geometrical correctness is made diffi-cult because tension and stress induced during welding and storage can change the dimensional characteristics and make the flanges out of spec. Laser systems can measure many geometrical features on many different components, including flatness, parallelism, bore position, level and straightness. Flange flatness, flange parallelism, blade hubs, blade flanges, base frames and foundations all can be measured using the same system. Important features for fast measurements and one-person operation include wireless remote control of the laser, wireless communication to the handheld device and touch-screen operation.
