COB Industries introduces its innovative Weld Backing Tape® to support all welding currents, from 80 amps, up to as high as 600 amps, providing the support to produce perfect weld underbeads.
COB Industries said, “Weld Backing Tape® is a glass fibre weld backing system that supports and protects the weld root from oxidation. It will trap the inert gas from the weld torch to hold the gas surrounding the weld pool, effectively providing a back purge facility. We manufacture four grades of Weld Backing Tape for use up to 80, 160, 240 or 600 Amps.”
Each tape comprises of a 3” (75mm) wide aluminium adhesive tape backing strip, in the centre of which is a 1” (25mm) wide band of woven glass fibre matting running down the centre. The glass fibre matting has differing thicknesses to match the welding current in use.
