There should be no oil dirt or dust at the joints. The overlapping section of the HDPE impermeable membrane should not be debris, dew, moisture, etc. When there are debris, it is necessary to clean it up before welding.
The waterproof board needs to be regular and beautiful in the welding seam, and must not have sliding welding or jumping away.
At the beginning of welding every day, a sample of 0.9mm*0.3mm should generally be welded on site, with a lap width of not less than 10cm, and peeling and shearing should be stopped at the site. After the sample is qualified, it can be adjusted at the time.
