KATBAK CERAMIC BACKING BAR 13MM ROUND

KATBAK Ceramic Backing Bar 13mm Round – Premium Welding Backing Tile for Pipe & Plate Welding

Product Overview

The KATBAK Ceramic Backing Bar (13mm Round profile) is a high-temperature, heat-resistant ceramic backing tile engineered to support single-sided welding of pipes, plates, and vessels. Designed for root-pass welding applications, this 13mm round-groove ceramic bar ensures consistent weld pool control, uniform root penetration, and a clean, oxide-free underbead — eliminating the need for back-gouging or grinding.

Key Features

• 13mm Round Groove Profile – Precision-molded round channel supports controlled weld pool formation and consistent root bead shaping for medium-to-heavy wall thickness joints.
• High-Temperature Ceramic Composition – Withstands extreme welding arc temperatures without cracking, melting, or deforming, ensuring safe and stable backing throughout the weld pass.
• Self-Adhesive / Tape-Backed Options – Easy application to the joint underside with strong adhesive backing (where applicable) for quick, secure positioning before welding.
• Reduces Post-Weld Finishing – Produces a smooth, defect-free root bead, minimizing time spent on grinding, back-gouging, and rework.
• Compatible with Multiple Welding Processes – Suitable for GTAW (TIG), SMAW (Stick), FCAW, and SAW welding of carbon steel, stainless steel, and alloy pipe/plate joints.
• Segmented / Flexible Design – Bends and conforms to curved surfaces, making it ideal for circumferential pipe welds as well as straight plate seams.
• Consistent Weld Quality – Prevents weld metal sag-through, undercut, and porosity by fully supporting the molten pool during the root pass.

Applications

• Pipeline welding (oil & gas, water, and process piping)
• Pressure vessel and tank fabrication
• Structural steel plate welding
• Shipbuilding and heavy fabrication
• Power plant and petrochemical piping systems

Why Choose KATBAK Ceramic Backing Bars?

KATBAK ceramic backing bars are manufactured to strict quality standards, offering welders and fabricators a reliable, cost-effective solution for achieving code-compliant, defect-free root welds on the first pass. The 13mm round profile is specifically suited for medium-gauge pipe and plate applications where consistent root reinforcement and bead contour are critical.
