Ceramic backing material for welding

During welding, the backing is a support for the weld pool helping to achieve a compact root pass in all single-sided welding positions. Many rigid and articulated weld backing profiles are available to match a wide range of welding joint configurations: ■ Flat backing tapes ■ Shoulder backing tapes ■ Raised backing tapes ■ Round backing tapes They are made of a water repellent ceramic and are secured with an adhesive aluminum tape or a metal rail to adapt to any welding position. The ceramic weld backing procedure generates a significant productivity gain. ■ Increase in the first pass deposit rate ■ Simplification of chamfering preparations ■ Total penetration without turning workpieces ■ Total penetration of hard-to-reach joints in reverse position ■ Eliminates the risk of weld collapse ■ Eliminates need for grinding, gouging and rooting of the weld
