Weld backing tapes provide a support for molten metal below welds. Huntingdon Fusion Techniques(HFT) has introduced a new, heavy-duty weld backing tape that can help manufacturers to obtain good underbeads even when welding at 600 Amps. The tape has an aluminum adhesive backing strip with the glass fiber running down the center of the tape. This varies in thickness depending on the welding current being used. The tape is used when it is difficult to control the root profile well in manual welding, and in production lines with automated welding that needs to be performed rapidly while still forming good underbeads.

HFT’s Argweld Weld Backing Tape is available in 80, 160, 240 or 600 Amp thickness, with the latter being the newest product in the range. The tape is suitable for use in MIG, TIG (GTAW) or Plasma (PAW) systems and does not affect the chemistry of the weld.
