F. Thermal bonding the Liner
1. Using leftover material, cut 3” to 4” wide strips the length of the seams
(Figure 17)
Figure 17
2. Prepare for Bonding
Clean working area
No debris between bonding parts
Clean nozzle
Preheat thermal bonding unit to 525° F
Allow 10 minutes for welder to stabilize
3. Lay liner pieces with about a 2” overhang
4. Lift upper liner until lower liner edge is nearly exposed
5. Set the nozzle at a 45 degree angle with the joint
6. Slowly run the nozzle parallel to the upper edge, use the roller to evenly
secure the 2 pieces (Figure 18)
The edge of the upper liner should show some signs of “bleed”
Discoloration is a sign that the bond is too hot, check temp and
clean nozzle
7. After bond has cooled (approx. 30 min) check the integrity of the weld
