Meta Vision, UK, is a leading supplier of laser vision systems to the tube and pipe sector. In recent years, Meta has had particular success in helping to improve the quality of output from both longitudinal and spiral pipe mills worldwide. There are three main variants of Meta’s VistaWeld system for pipe mills. Firstly, the VistaWeld provides mill control functions for spiral pipe mills. Secondly, the dual head VistaWeld system is designed for offline welding stations on spiral mills. Finally, the multi head VistaWeld MDK is used for UT guidance. VistaWeld is an advanced system for spiral pipe mill control. The well-proven system has been installed all over the world on both one-step and two-step mills in the last ten years. Continuous advances have brought the system to the point where advanced mill control functions can also be offered. With the rise in popularity of two-step mills, a special variant of VistaWeld specifically for the offline welding stations of two-step spiral mills has been developed and proven. Meta’s unique three-stripe laser sensor provides unrivalled performance and reliability, in combination with special software and functions for the ID welding head. Meta has also perfected the application of multi head laser vision systems for tracking

weld beads. One to four laser sensors can be connected to a single PC control and used to keep each UT head positioned correctly on the weld bead. This reduces the number of false indications and frees the machine operator to con- centrate on the UT signal – not on keeping the probes centred on the weld bead.
