Esab 693000135 Round Ceramic Weld Backing 36 Ft/box

Product Description

The ESAB 693000135 is a round ceramic weld backing designed to support single-sided welding operations by providing a stable, heat-resistant surface on the back side of a weld joint. Each piece measures 1 inch in length and 1/2 inch in diameter. Ceramic backing holds the molten weld pool in place, promotes full-penetration welds, and eliminates the need for back-gouging or back-welding on many joint configurations. This product is installed by certified welders and welding professionals working in fabrication, structural, and pipe welding applications. Each box contains 36 packaging feet of backing material and weighs 1 pound.

Round ceramic weld backing is commonly used in structural steel fabrication, pressure vessel manufacturing, pipe welding, and general metal fabrication where single-sided access is required. The round profile suits circular or tubular joint geometries. It is appropriate for both shop and field environments where back-side access is limited or impractical. Welding contractors and fabricators select this backing type to improve weld quality consistency and reduce post-weld finishing labor.

Key Features

• Round backing profile suited for tubular and curved weld joints
• Ceramic construction withstands high weld pool temperatures
• 1 inch length per piece for precise joint coverage
• 1/2 inch diameter for consistent fitment on round joint geometries
• Supports full-penetration single-sided welds, reducing need for back-gouging
• 36 packaging feet per box for job-site or shop use

Compatibility

Designed as an OEM-style ceramic weld backing for use in single-sided welding applications on round or tubular joints across common base metals used in structural and fabrication welding.

Installation Notes

Ceramic weld backing is applied by qualified welders to the back side of a prepared weld joint prior to welding. Ensure the joint surface is clean, dry, and free of mill scale, oil, and moisture before applying backing. Secure the backing firmly against the root of the joint to prevent weld pool leakage. Follow applicable welding procedure specifications and relevant codes such as AWS D1.1 when using backing in structural applications.
