Fiberglass Weld-Backing Tape
Stick this flexible tape to the back of welding seams to contain spatter and prevent oxygen, water vapor, and other gases from weakening the weld. Also known as back purge tape, it’s used for welding flat sheets, large tanks, and other applications where filling the space behind the seam with purge gas is difficult or expensive. Form the fiberglass spine into a small ridge over the weld joint, then press the adhesive foil down on each side. Compatible with MIG, TIG, and stick welding.
Apply 200 amp tape to thin welds on aluminum, cast iron, nickel and copper alloys, and steel.
Use 600 amp tape to shield thick welds on dense metals, such as stainless steel.
