Welding inspection control measures 1) Product surface inspection: After the HDPE geomembrane is unfolded, it is necessary to visually inspect for defects and mark the areas with defects or doubts for repair. 2) The inspection of welds is divided into visual inspection and leak testing (non essential). Visual inspection of welds mainly involves careful inspection of the appearance of the weld, the treatment of T-shaped and cross shaped welds, and the presence of impurities on the base layer. 3) Non sexual testing: Inflatable (double weld) Double weld inflation testing: Gas sealed at a certain pressure is used to determine its airtightness by detecting the changes in the pressure gauge attached to the detection needle.
