Weld Back-up Tapeweld

Fiber Glass Weld Back-up Tape

   Product Specifications:

Safex Fiber Glass Weld Back-up Tape is a 75 mm wide, metallic heat resistant adhesive tape, which has a 25 mm wide cloth strip of fiber glass which is held up against weld preparation area and maintains weld in same plane as plates or tubes being joined.
Available in light duty use up to 80 amps and heavy duty for use up to 160 amps. For above 160 amps, different product of fiberglass band with refractory silica glass in the center is available.
Both the types of tapes, i.e. light duty and heavy-duty tapes, are available in 20 Meters long rolls.

   Advantages:

	Facilitates perfect weld penetration and proper merging
	Saves argon gas as no purging will be necessary, which results into less cost on purging gas.
	Imparts X-ray quality back beads on root pass
	Makes process faster as it saves time in preparation and assemble. Welds one side only
	Deposits more weld metal
	Root weld and fill in one pass
	Eliminates back chipping
	Eliminates defects and reworks
	Eliminates costly unnecessary grinding and gauging
	Provides incombustible, high temperature stability. More flexible, low thermal conductivity, good thermal shock resistance, good mechanical and chemical agents resistance, good electrical properties.

Ceramic Weld Back-up Tape

   Product Specifications:

Safex ceramic weld back-up tape is composed of specially designed ceramic tiles overlaid on a temperature resistant metal backing. It is specifically designed for different types of welding applications. Different shapes of ceramic tiles, helps to deposit more weld metal for more accurate welding.

Safex Ceramic Weld Back-up Tape is 100 mm wide, metallic heat resistant adhesive tape, which has ceramic tiles of different size and different shapes, as per the welding requirement.

Regular available size of this tape is 20 inches long pieces.

   Advantages:

	Imparts X-ray quality back beads on root pass
	Welding required on one side only, no welding on the back side. No need for back gouging, dye penetrant test & re-welding. No scope for rejections, failure to macro/micro examination & radiography.
	Deposits more weld metal for full penetration
	Root weld and fill in one pass
	Quick execution, saves man power & time which results into better improved productivity.
	Eliminates defects and reworks, improves quality
	Eliminates costly unnecessary grinding and gauging
	Useful for different types of weld joints, i.e. single & double V butt joints, dished end/shell to manhole/hand hole, tube plate to shell etc.
	Utilizable for every metal
	No oxidation, no pollution no hydrogen inclusion.
	Can use for any type of welding process, e.g. CO2 semi automatic welding & automatic welding, SWAM, GMAW, MIG, SAW, SEG etc.
	Root pass to final pass by continuous & fast welding processes possible. E.g. FCAW, SAW. I.e. elimination of non-continuous & siow SMWA, TIG processes.
	Ensures enhanced safety, comfort & best work environmental condition to the welder & fitter.
