 Economic advantages

  • No gouging, grinding and reworking of the weld root.
  • Full penetration joints without turning over the workpiece.
  • High deposition rate processes can be used for the first pass.
  • Simplified bevelling through the elimination of root faces.

Application

  • Using KERAL backing does not require any special preparation, except that the surfaces to which the adhesive tape is applied must be free of grease, oil and loose rust.
  • The sections overlap : the assembly is sealed by overlapping the adhesive tape from each section to the next.

KERAL 01

Semi-porous type.

Compact ceramic at very low moisture pick up (< 0,5 %).

A middle fusion point allowing an optimal use at low and medium current (80 to 250 A).

KERAL 02, KERAL 03, KERAL 05, KERAL 07, KERAL R

Hyper compact ceramic with low moisture pick up (< 0,1 %).

High fusion point allowing the use of a very high welding current.

Example : MIG-MAG, flux cored wire and submerged arc (200 to 400 A).

Fibreglass Backing Tape

KERAL 07 S

Fibre-glass complex and powder ceramic.

Enables an extreme flexibility.

Low fusion point allowing a very good penetration even with low welding current.

Example : TIG (80 to 200 A).

KERAL F

Braided fibre-glass band.

Permits an extreme flexibility.

Low fusion point allowing a very good penetration even with low welding current.

Example : TIG (80 to 200 A).
