INSTALLATION QUALITY ASSURANCE The Installation Quality Assurance Plan include routine trial welds at the beginning of the work day, where small samples of liner are welded and tested for shear and peel. Trial welds assist to check and adjust welding equipment heating temperatures, roller pressure and variable speed controls. Once calibrated, the welding commences. Destructive seam testing involves cutting out a section of the seam and tested on site. The overlapping welded strips are tensioned in opposite directions to observe weld strength or peeling. Random non-destructive vacuum or air channel tests may be conducted on the Double-track fusion welded seams.
