Seam Probing
All welded seams must be probed with the Flex Seam Probe to determine
the quality and integrity of the weld. Allow the hot air welded seam to
cool to ambient temperature before beginning the probing process.
Apply pressure and pull the point of the seam probe along the edge of
the seam. The tool will not penetrate the edge of a properly welded
seam. Repair any voids discovered by cleaning and re-welding the seam.
After the repair cools, probe the area to confirm the proper weld.
All welded seams must be probed to test for secure welds
Defects and Repairs
Voids are repaired by cleaning the two sections of membrane and
inserting the nozzle of the hand welder into the void. Apply pressure
with the silicon roller and roll the top surface towards the outer edge to
cause the membrane to fuse together wrinkles in the seam, burn marks
or overheated areas, and any area where adhesive contaminated the
seam must have a patch installed over the defective area.
When installing a patch the area to receive the patch must be
thoroughly cleaned. The patch is to be made from the reinforced plain
backed membrane. The patch should be sized to extend past all edges
of the defective area a minimum of 2” with all corners rounded. The
patch is hot air welded to the existing membrane.
