FuseRing Details

Solid State Fusion and FuseRing in tandem are the natural evolution of pipeline construction.

(Based on Patent # U.S. 9,644,769 B1 and Patent Pending applications.)

Solid State Fusion process has an inherent restriction. One part has to rotate thus limiting joining pipeline to valves or any segment that is non linear.

FuseRing steps in and acts as an intermediary between two non rotatable objects. This enables the entire pipeline segment to be joined using one system of fusion.

Furthermore U.S. Patent Application pending enables any pipeline to be laid in one continuous motion eliminating multiple handle points.

Macroetch Evaluation Test Report
A random transverse section of the weld pipe was cut and prepared according to ASTM E3-11. The section was etched in 5% Nital and then examined at 10X magnification for general comments ao weld imperfections and evidence of lack of fusion.

Examination of the specimen showed that the weld appeared to have no undercut, cracks or inclusions (refer to Figure 1). There was complete fusion observed throughout the weld. One void was observed in the weld metal slightly below mid-thickness on the inner diameter side measuring 0.33mm (refer to Figure 2).

Specimen examined at 6.3X, photo shown at approximately 6.3X. Etched in 5% Nital

Specimen examined at 50X, photo shown at approximately 50X. Etched in 5% Nital
