Product: Weld Backing Tape™

Description: This tape is best used for the backing of welds, where purging is required but neither easily achieved nor economically viable. It is a glass-fibre weld-backing system that supports and protects the weld root from oxidation. It is designed to trap the inert gas from the weld torch to hold the gas surrounding the weld pool, effectively providing a back purge facility. It’s available in three grades, and all consist of a high-temperature-resistant aluminum backing foil with a heat-resistant band of woven glass-fibre cloth. The thickest cloth will support single-pass welding at weld currents up to 240 A without changing the chemistry or metallurgy of the weld.
