How Fiback Works

Align

Align desired base metals with the required root gap. Center the fiberglass strip over the backside of the root gap.

Position

Position the fiberglass strip in a convex shape away from the backside of the weld area to contain the purge gas from the torch tip but avoid consuming the material.

Press

Press the adhesive sections of tape along the sides of the root gap to the base metal, continuing to center the fiberglass strip. Remember to peel the release liner from the aluminum tape while progressing along the weld joint. This procedure ensures the adhesive on the aluminum tape is free from debris and foreign matter.
After Fiback has been applied to the entire length of the metals being joined, press outer adhesive edges again to create an air tight seal between the tape and the base metal.

Weld

Begin welding the desired seam.
