Weld Backing Tape, with no true melting point, helps to support weld roots and prevent ‘sugaring’ or ‘grapes’. Suitable for stainless, carbon, duplex, and chrome steels, as well as other reactive alloys, Weld Backing Tape is used for manual and automatic welding. It can help achieve higher welding speeds and dramatically reduce the amount of post-weld cleaning required.

 

The Weld Backing Tape comprises a 3-in. wide aluminum adhesive tape that has a 1-in. wide fiberglass band in the center onto which the weld can be cast.
