Backing tape used in the welding of seams or runs help to prevent weld failures and produce flat, slag-free welds requiring no grinding or backgouging. Weld Backing Tape from Huntingdon Fusion Techniques has been engineered for maximum heat resistance and to provide a flat, close-fitting surface under the weld. Helping to eliminate rewelds and reworking due to defects, thus decreasing costs, the tape also increases weld productivity, cutting setup and weld times significantly. The metallic, adhesive tape has a glass-fibre strip which is held up against the weld preparation area and maintains the weld in the same plane as the plates or tubes being joined. In certain circumstances, the use of backing tape can replace purging of the underside as oxygen is absent and coking, oxidisation or discolouration prevented. It is therefore suitable for situations where the use of purge gas is impractical or expensive.
