HELP Backing Tape for Welding

Backing Tape

GLASS FIBER TEXTILE (550c) incombustible, high temperature stability (max temperature:550c). good flexibility, low thermal conductivity, good mechanical and chemical agents resistance, good electrical properties.

SIL-TEX TEXTILE (1000c) Good abrasion resistance, incombustible, good mechanical and chemical agents resistance, good dimensional stability, good flexibility, low thermal conductivity, high temperature stability (max temperature 1000c). good thermal shock resistance.

It is possible to weld onto the tape with MIG, Stick, Tig or Plasma processes, so long as the recommended current levels are not exceeded.

Weld Backing Tape

A simple alternative to back purging, HELP Weld Backing Tape can offer huge benefits by simply applying a strip of self adhesive welding tape to the back of the weld.
Whether the quality of the finished product is dictated by weld integrity or just cosmetic appearance, HELP Weld Backing Tape can offer huge benefits:

1.
Less back purging
2. Less post weld dressing
3. Less fettling
4. Smoother flatter welds
5. One sided welding
All these can be minimised or actually eliminated by simply applying a strip of self-adhesive Welding Tape to the back of the Weld.  This is not a gimmick; this product has been available for decades and companies that use it do so again and again.
Applications include large diameter pipes and tanks, where it is not practical or too expensive to back purge with gas.  This simple backing tape dramatically reduces the time and aggravation involved in welding these products.
The tape comes in 2 standard sizes of 100mm wide fiber (up to 550° C) and 100mm wide (up to 1000° C) in roll lengths of 25m., on Aluminum back with adhesive on both sides, A Silicon glass and fiber weave down the center of the tape 25mm wide is placed directly under the weld.
