About
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.
Fiback 200 AMP
- Light duty
- Sufficient for thinner materials, such as aluminum, carbon steel, chrome steels, cast iron, nickel and cobalt alloys, copper nickel and many more
- Often used in general fabrication shops and for manufacturing pressure vessels and aircraft components
Fiback 600 AMP
- Heavy duty
- Typically used for denser metals, such as stainless steel, duplex stainless steel and other metals depending on thickness
- Often used for projects in the commercial and military ship manufacturing industry
- Can be used with automated equipment for more accurate results
Features and Benefits
Flexible
- 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
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.
