How ceramic welding backing tape works?

alignment

Align the required base metal with the required root gap. Place the fiberglass tape in the back center of the root gap.

position

Place the fiberglass tape in a convex position away from the back of the welding area to contain the gas blown from the top of the welding gun, but avoid material consumption. Journalism

Press the adhesive part of the tape onto the base metal along both sides of the root gap, and continue to center the fiberglass tape. When working along welded joints, remember to peel off the release pad from the strip. This procedure ensures that the adhesive on the strip is free of chips and foreign material.

After the tape is pasted on the whole length of the connecting metal, press the outer edge again to form a seal between the tape and the base metal.
