Backing Tape

Backing Tape is a heat resistant aluminium tape with a woven fiberglass center strip, designed to eliminate or reduce the need for purging and create a weld pool enclosure.

Backing Tape also:
• reduces setup time
• eliminates/minimizes need for back purging
• reduces post-weld grinding
• cuts down on post-weld grinding
• increases weld productivity, reduces costs
• heat resistant

	Step 1: Peel away backing tape covers from both sides. Gently coil the adhesive tape edges back and push the woven fibreglass strip outwards

	Step 2: Center and apply the woven fibreglass strip firmly to the backside of the root gap. Peel away tape cover from the other side

	Step 3: Beginning from the center and slowly moving outward, apply the adhesive aluminium tape to the area surrounding the root gap, providing a smooth, air-free seal

Backing Tape can be used with carbon steel (left photo) or stainless steel (right photo), for sheet to sheet or pipe to pipe welding. The 1/4 gap between the sheet metal has been welded with .045” flux core. Notice that the fibreglass has not burned away and there is no appearance of oxidation.

Backing Tape consists of two outer adhesive strips separated by a woven fibreglass center strip. The adhesive edges stick to the area surrounding the root gap with the woven fibreglass strip being positioned to the backside of the root gap.
