Argweld® Weld Backing Tape

Extending the Argweld® range of purging products, Huntingdon Fusion Techniques Limited, are providing an economical non metallic weld backing system for the backing of welds, where purging is required but not easily achieved, for quality and for supporting weld roots to improve weld bead profiles.

Typically for the welding of thin wall stainless steel sheet and vessels from one side only, the backing tape can be attached to the backside of the weld, to support the weld pool, keep the argon from the weld torch surrounding the weld pool and eliminate the need to back purge, while giving a consistent high quality underbead profile.

For purging large vessels the tremendous savings of purge gas and waiting time, pays for the use of the backing tape many times over.

The high temperature heat resistant adhesive aluminium backing foil is 75mm (3") wide and in the centre is a heat resistant band of woven glass fibre cloth 25mm (1") wide.

The glass fibre cloth has a weight of 1000 grams per square metre.

The 80 Amp tape comes in rolls of 25m (80") length and the 160 Amp tape rolls are 12.5m (40") long.

The thickest cloth will support single pass welding at weld currents up to 240 Amps, without change to the chemistry or metallurgy of the weld.
