one side weld backing strips
Widely used in one side welding technique such as CO2 semi-automatic and automatic welding

one side weld backing strips 

 Description

1. a ceramic backing material for welding

2. get perfect penetration without material for welding

3. get perfect penetration without cracks or hairline opening

4. saves welding cost approx. 40% & time approx 50%

5. suitable for ship building, marine facilities, plants and other steel structures

6. widely used for one side welding technique such as CO2 semi-automatic welding and automatic welding.

Feature

Ceramic backing 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 ceramic backing is heat-treated at high temperature, 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 temperature created good beads on the back side.

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

Advantages 

1. No back side grinding required.

2. Saves cost / Saves time.

3. X ray quality back beads.

4. No scope for rejections, failure to macro/ micro examination & radiography. Eliminates defects and  reworks, improves quality.

5. Deposit more weld metal for full penetration. Minimize rework & reweld.

6. 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

7. No oxidation, No pollution, No hydrogen inclusion.

8. Ensures enhanced safety, Comfort & Best work environmental condition to the Welder & Fitter.
