Ceramic Weld Backing Tapes

CERBACK is a ceramic backing material for welding, to get perfect penetration without material for welding, to get perfect penetration without cracks or hairline openings, saves welding cost approx. 40% & time approx 50%, developed first time in INDIA by technocrats & marketed by us. CERBACK is suitable for ship building, marine facilities, plants and other steel structures and is widely used for one side welding technique such as CO2 semiautomatic welding and automatic welding.

Ceramic Weld Backing Tapes
CERBACK is a fine ceramic product composed of adequately mixed natural inorganic substances (kaolin, talc, alumina, magnesia etc.) that are heat-treated at high temperatures of 1,350ºC~1,400º C span.

Since CERBACK is heat-treated at high temperatures its shock resistance to rapid heating and cooling is excellent (coefficient of thermal expansion is 1.85 - 2.5 x 10-6 at 1,000º C ) and maintains superb stability against the high temperatures created good beads on the back side.

CERBACK has excellent characteristics of ceramic such as anti-acid, anti chemicals.and anti-corrosion and also caused no change or reaction of steel at the time of welding.

Advanatges of Ceramic Weld Backing Tapes
• No back side grinding required.
• Saves cost / Saves time.
• X ray quality back beads.
• No scope for rejections, failure to macro/ micro examination & radiography.
  Eliminates defects and reworks, improves quality.
• Deposit more weld metal for full penetration .
  Minimize rework & reweld.
• Useful for different types of weld joints, i.e. single & double V butt joints,
  dished ends / shell to manhole / hand hole, tube plate to shell etc
• No oxidation, No pollution, No hydrogen inclusion.
• Ensures enhanced safety, Comfort & Best work environmental condition to
  the Welder & Fitter.
