Fiback Fiberglass Weld Backing Tape is an innovative substitute for traditional back purging methods that provides protection to the backside of the weld environment and ensures a high quality finish. Fiback is flexible, heat resistant, and halogen and fluorocarbon-free, enabling it to be a complete solution for plate, sheet and pipe welding needs. This welding tape is composed of two adhesive areas around the outside edges with a center fiberglass strip, heat resistant up to 1,022°F (550°C) and withstanding applications up to 600 amps.
Suitable for SMAW (stick), TIG, and MIG Welding processes, Fiback can conform to various shapes making it superior to more rigid solutions that develop stress points between pieces and are prone to cracking and breaking over time. Fiback reduces set-up, clean up and weld time; eliminates post-weld grinding and back gouging and increases work efficiency while minimizing costs.
Suitable for stainless, carbon, duplex and chrome steels as well as other metals
Woven fiberglass and malleable aluminum tape easily conform to a number of complex shapes and uneven surfaces
A supportive weld pool is created by forming the tape into a convex shape resulting in an oxygen-free weld bead
Consistent in thickness, Fiback creates a continuous bead, ideal for lengthy applications

High Quality & Safe Components
Halogen and chlorofluorocarbon free, creating a safe work environment
Fiberglass formulation is also free of mercury, antimony, fluoride, bromide, phosphorous, sulfur, and lead
Virgin aluminum foil coated with free acrylic base adhesive
Tightly and finely woven, unadulterated fiberglass

Compatibility & Process Applications
Suitable for SMAW (stick), TIG and MIG welding processes
Ideal for welding sheet-to-sheet, plate-to-plate, pressure vessels, large diameter pipes and tanks, longitudinal and circumferential seams and anywhere that a back purging is not possible or very costly with gas

Increases Efficiency and Savings
Eliminates the need for back purging, increasing weld productivity and reducing labor costs
Saves gas as well as down time, allowing the user to bypass filling large structures; such as pressure vessels and bore pipes; with argon
Significantly reduces post-weld clean up time by eliminating gouging & grinding
Perfectly compatible with orbital welding machines
