Weld backing tapes are manufactured in India with foreign technical consultation even for X ray quality welding. The weld backing tapes are flexible, self adhesive aluminum foil with non metallic ceramic backings
which do not require any magnetic clamp or fixture to be fixed in position. These are suitable for preheat up to 100°c to 150° c are available in various shapes for different types of weld joints. Like metal backing bar, it does not contaminate the weldment & also does not become part of it.
tapes when property positioned & fixed face to face under the weld-joint & welded. The roots pass welding results in uniform & sound penetration. Ultimately it eliminates back gouging / grinding & Rewelding form other side which leads to number of advantages.
SALIENT FEATURES OF CERAMIC WELD BACKING TAPES
· It is flexible & self adhesive and does not require any magnetic clamp or fixture to fix underneath the weld joint.
· It gives support to the root pass weld pool to give a desired shape.
· Can be used for Circular & Longitudinal weld seams.
· Tape can be used in all positions and for all weld joint configuration.
· GMAW / FCAW / (MIG / MAG) & SAW Welding Processes can be used directly from Root Pass to Final Pass.
· Tape can be used for welding of Carbon Steel, Alloy Steel, Stainless Steel & Aluminium etc.
· Gas purging not required while welding metals like Stainless Steel.
· No contamination with the weld pool, so no change in mechanical properties of the Weldment.
· It ensures enhanced safety, comfort & healthy work environmental condition to the Welder & Fitter.
