Remove any <br />foreign material from the area to be seamed prior to the beginning of seaming <br />operations. <br />3. Welding equipment shall be capable of delivering sufficient amounts of heat <br />and pressure to the seam area to produce a continuous thermal weld. <br />4. Continually inspect all seams. If any seam defects are noted, cease seam <br />production immediately, remove affected area, adjust equipment and repair <br />as outlined in below section. <br />D. Repair <br />1. Inspect the liner for punctures, tears and other defects. <br />2.
