WELD BACKING TAPE™
Extending the Argweld ® range of purging products,
Huntingdon Fusion Techniques 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.
160 and 240 Amp tape rolls are 12.5m (40”) long.
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.
Features:
With the thickest cloth Argweld® Backing Tape will support
single pass welding at weld currents up to 240 Amps, without
change to the chemistry or metallurgy of the weld.
