Ceramic backing holds molten weld metal in place during the first pass, allowing welders to achieve full-penetration welds without a backing bar or second-side access. This piece measures 1 inch in length and is cut at a 45-degree angle, making it suited for corner joints and angled seam configurations. The FBF backing type is a formed ceramic tile backed with adhesive tape that bonds directly to the base metal. Licensed welders and certified welding inspectors typically specify ceramic backing for structural, pipe, and plate work where backgouging is not practical.\u003c\/p\u003e\u003cp\u003eThis ceramic weld backing is used in structural steel fabrication, shipbuilding, pressure vessel construction, and general plate welding. The 45-degree angle profile fits joints where a straight strip would not conform correctly to the weld groove geometry. It is appropriate for MIG, TIG, and submerged arc welding processes where a clean, supported root bead is required. Each box contains 36 packaging feet of backing strips.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFBF backing type with adhesive tape for direct bonding to base metal surface\u003c\/li\u003e\n\u003cli\u003e45-degree angle cut for compatibility with angled joints and corner configurations\u003c\/li\u003e\n\u003cli\u003e1 inch length per strip supports controlled root bead formation\u003c\/li\u003e\n\u003cli\u003eCeramic construction withstands welding heat and prevents burn-through on the root pass\u003c\/li\u003e\n\u003cli\u003eEliminates the need for backgouging or second-side access on qualifying joints\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style ceramic weld backing strip for single-sided groove welds in structural and fabrication applications where a 45-degree angle profile is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eApplication is performed by a certified welder or welding operator following applicable AWS or shop welding procedure specifications. Clean the base metal surface thoroughly before applying the adhesive backing to ensure proper adhesion and prevent contamination of the weld pool. Do not weld over damaged or partially adhered backing strips. Remove ceramic residue after weld cooling per the project quality plan.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Type\u003c\/strong\u003e: FBF Ceramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAngle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaging Feet per Box\u003c\/strong\u003e: 36\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ESAB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 693000291\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ESAB","offers":[{"title":"Default Title","offer_id":51540906180914,"sku":"693000291","price":301.87,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/adf036c4db096c8d9c97fe1ab41dca12.jpg?v=1785865689","url":"https:\/\/voomisupply.com\/products\/esab-693000291-fbf-ceramic-weld-backing-1-inch-45-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
