Esab 693000226 Ceramic Weld Backing 350R 36 Ft/box

Product Description

The ESAB 693000226 is a ceramic weld backing strip designed to support full-penetration welds from the root side of a joint. Ceramic backing holds molten weld metal in place during single-sided welding, allowing the welder to achieve a consistent root bead without access to the back of the joint. Each strip measures 1 inch long. The 350R backing type is suited for use on flat and slightly curved weld joints. Each box contains 36 packaging feet of backing. This product is used by certified welders and structural fabricators working in shop or field environments.

Ceramic weld backing strips are commonly used in structural steel fabrication, shipbuilding, pipe fabrication, and heavy equipment manufacturing. They are applied to the back side of a butt weld joint before welding begins, eliminating the need for back-gouging or back-welding operations. The 350R profile is designed for flat or low-curvature joint configurations. This product is appropriate for MIG, flux-cored, and submerged arc welding processes on carbon steel and similar base metals.

Compatibility

Designed as an OEM-style ceramic weld backing consumable for single-sided butt weld joints on flat or low-curvature surfaces. The 350R profile is a standard ESAB backing configuration. Supplier data also lists backing type 215R as an associated attribute for this SKU.

Installation Notes

Ceramic weld backing is installed by the welder or fit-up technician before arc welding begins. The joint must be properly fit and tacked before backing strips are applied to the root side. Ensure the ceramic strip is firmly seated against the base metal with no gaps that could allow weld metal to leak. Follow applicable welding procedure specifications and AWS or applicable structural codes for joint design and qualified procedure requirements.
