CERBACK is a ceramic backing
material for welding, to get perfect penetration without cracks
or hairline openings, saves welding cost appox. 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.
Product
Feature 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.

Models CERBACK speeds production, improves worker efficiency and
reduces costs. It allows one-sided welding for steel, alloys and
aluminum of any thickness. The product is composed of ceramic tiles
attached to aluminum tape on which specific heat-resistant adhesives
are spread. Designed for one-sided welding, it produces smooth and
homogeneous back beads even with high electric current. This product
is designed to provide welds that are free from porosity and
inclusions. The CERBACK series can be used with most types of
one-sided welding including GMAW, SMAW, FCAW, GMAW, SAW, MIG, TIG,
PLASMA, CO2, SEG ARC, Almost all types of welding procedures & for
all types of metal.
APPLICATIONS * Heavy industries such as shipbuilding
* Marine-plant industries which have mostly employed two sided
welding that accompanies back gouging work for full penetration
* Fabrication industries doing double side welding
* For Wind Mills

CERBACK “Ceramic Weld Backings” are manufactured in many shapes and
sizes for the conditions of
heavy metal fabrication.
When properly positioned and attached to the back-side of weld joint
openings, produce a condition which
results in root welds free of defects.
The use of CERBACK Ceramic
Backing can be justified by the following advantages:
• Reduction of labour to elimination of many operations (cutting
the
root of weld, pre-welding, rotating the construction),
• Welding operations are carried out on one side in technically
convenient positions,
• Semi-qualified welders can be employed,
• Eliminating defects of weld in its root part and eliminating
necessity to do repairs.
Standard length of each backing strip is 600 mm
