Commonly in the ship building industry many joints are welded from a single side using a ceramic backing tape. The ceramic backing tape is like a mold to pour metal in, but in this case the electrode will fill that mold.
When ceramic backing tape is used it allows for full joint preparation and outstanding weld quality. This in return gives full control of the shape and penetration of the back side of the weld. Once the weld is finished,
the ceramic tape is simply peeled off, and thrown away. The great think about using ceramic backing tape is that it is just like welding an open root butt joint, but requires much less skill! The pictures below are of the
first time I used ceramic backing tape on a 3G weld joint. Its real easy as long as you keep the arc in the puddle!
