KATBAK® Ceramic Backing Bar – 1" x 1" Tile, 7/16" Groove

Premium Gullco KATBAK Ceramic Weld Backing for X-Ray Quality Root Passes

The KATBAK® Ceramic Backing Bar (1x1 tile, 7/16" groove) is a professional-grade ceramic weld backing designed to deliver flawless, X-ray-quality back beads on root pass welds — every time. Manufactured by Gullco, a trusted leader in welding automation and ceramic backing solutions, this backing bar allows welders to complete a full weld from one side only, eliminating the need for back-gouging, grinding, or costly rework.

Key Features

• 1" x 1" tile size with 7/16" groove — sized to accommodate root gaps and provide ample space for slag runoff during welding
• Single-side welding capability — root weld and fill pass can often be completed in one operation
• X-ray quality back beads — produces clean, defect-free welds that meet strict inspection standards
• Non-toxic ceramic construction — safe for extended shop use
• Wide heat-receptive, pressure-sensitive adhesive foil — ensures strong adhesion to the workpiece and stays in place during welding
• Reduces defects and rework — minimizes costly downtime from failed inspections or repairs

Ideal Applications

This ceramic backing tile is well suited to processes involving slag, including flux-cored (FCAW), submerged arc (SAW), MIG (GMAW), and MMA/stick welding. It's commonly used in pipe welding, pressure vessel fabrication, structural steel work, and any butt-weld joint application where rear-side access is limited or unavailable.

Why Choose KATBAK Ceramic Weld Backing?

Welders and fabricators rely on KATBAK ceramic backing bars to save time and material while achieving consistent, high-integrity welds. By supporting and shielding the weld root from the back side, this backing bar helps you deposit more weld metal per pass, reduce gas consumption, and pass demanding code inspections — all while lowering labor costs associated with grinding and rework.
