KATBAK Ceramic Backing Bar 1" Triangular — Premium Ceramic Weld Backing Tile Achieve X-ray quality root pass welds in a single pass with KATBAK Ceramic Backing Bar 1" Triangular, the trusted ceramic weld backing solution for submerged arc, flux-cored (FCAW), MIG (GMAW), and MMA welding processes. Product Overview The KATBAK Ceramic Backing Bar 1" Triangular is a purpose-engineered ceramic weld backing tile designed to support and shape the root pass on butt and groove welds. Its triangular profile creates full-face contact with the joint rather than the single-point contact typical of round backing tiles, giving welders superior support against burn-through and more consistent, defect-free back beads. Mounted on a wide, heat-resistant, pressure-sensitive adhesive foil, the backing bar adheres firmly to the reverse side of the weld joint. As the weld progresses, molten slag and weld pool are contained within the recessed channel of the ceramic tile, protecting and precisely shaping the external bead from beneath — eliminating the need for back gouging or grinding. Key Features 1-inch triangular ceramic profile — full-face contact for stronger, more stable joint support Compatible with SAW, FCAW/GMAW, and MMA (SMAW) welding processes X-ray quality back beads achievable on root pass, from one side of the joint only Wide, heat-receptive pressure-sensitive foil for superior adhesion to the workpiece Non-toxic ceramic construction — safe for industrial fabrication environments Single-pass welding capability — weld and fill in one pass, saving time and consumables Eliminates costly rework — no gouging or grinding required to clean up the back side of the weld Why Choose Katbak Ceramic Weld Backing? Backing bars like the KATBAK Triangular series are engineered to help fabricators and pipe welders: Reduce production time by welding from a single side Deposit more weld metal per pass for stronger joints Minimize costly defects, rejects, and rework Improve consistency across long production runs, thanks to reliable adhesive backing Ideal Applications This ceramic backing bar is well suited for structural steel fabrication, pipe and vessel welding, shipbuilding, and any application requiring a strong, full-penetration root weld without the ability to access the back side of the joint for gouging or finishing.
