　　Quality Inspection Method for HDPE Geomembrane Hot Melt Double Track Welding

　　There are two types of welding quality testing for HDPE geomembranes: non-destructive testing (leak testing) and destructive testing. The double weld formed by hot melt welding is inspected using the inflation method, while the single weld formed by extrusion welding is inspected using the electric discharge method.

　　1. Inflatable method testing

　　Seal both ends of the HDPE geomembrane weld cavity that needs to be tested. After connecting the testing equipment, insert the measuring needle into one end of the cavity. Start the air pump, input high-pressure gas to reach 0.15~0.2MPa, and stop pressurization. Within 1-5 minutes, there was no significant decrease in pressure. When the other end was opened, the gas in the cavity disappeared. The Guizhou HDPE anti-seepage membrane slurry pool and 0.5mm anti-seepage membrane indicated that the entire weld seam passed the inspection. If the pressure gauge drops significantly within 1-5 minutes, it indicates that this weld seam needs to be repaired or reworked.

　　2. Spark detection method

　　By utilizing the characteristics of HDPE geomembrane as an electrical insulator, bright electrical sparks are generated when the instrument scans a part with holes or holes connected to the ground.

　　Testing procedure: embed fine copper wire before extrusion welding construction. Connect the power supply during testing at the Zhejiang PE geomembrane industrial landfill site. Use a detector to detect 1.5HDPE geomembrane at a height of about 30mm from the weld seam. If no sparks appear, the weld seam is firm. If sparks appear, it indicates that there is detachment, virtual welding, etc. in this area, which needs to be repaired and retested.

　　3. Destructive testing

　　Whether it is HDPE geomembrane double track hot melt welding double weld or extrusion welding single weld, the strength inspection of the weld, including shear strength and peel strength, must be carried out. The strength inspection is conducted at a frequency of testing every 1000 meters of weld seams (with at least five samples per group), designated by the owner or supervisor or randomly sampled for testing. Generally, it is selected to be conducted at locations where overheating, contamination, weld deviation, or insufficient welding are suspected.
