HDPE Butt Fusion Weld Inspection and Imaging Using Evisive
Above is an Evisive Scan#174; image of a 12 high density ployethylene (HDPE) thermal butt fusion weld. The several small indications in the melt zone of the weld are reconcilable to surface features, and do not represent weld defects. The scan above was performed using a manual rastertype pipe scanner (shown in the previous slide), but
