Esab 693000200 Triangle Ceramic Weld Backing 1 in 75 Deg

Product Description

The ESAB 693000200 is a triangle-profile ceramic weld backing strip used to support the weld pool during single-sided fusion welding operations. Measuring 1 inch in length with a 75-degree angle profile, this ceramic backing holds molten metal in place at the root of the joint, promoting full-penetration welds without requiring a backing pass from the reverse side. Each box contains 24 pieces. Ceramic weld backing is a standard consumable in structural, pipeline, and fabrication welding, applied by welders and certified weld technicians wherever back-gouging is impractical or impossible.

Triangle ceramic weld backing is suited for groove weld joints where the backing geometry needs to conform to a specific included angle. The 75-degree angle profile fits tight-angle joint configurations common in structural steel fabrication and shipbuilding. Single-sided welding with ceramic backing reduces labor time by eliminating the need to flip workpieces or back-gouge and re-weld the root. This product is intended for professional use in shop or field fabrication environments where AWS or applicable structural welding codes govern procedure qualification.

Key Features

• Triangle backing profile with 75-degree angle for precise root support at angled joint geometries
• 1 inch length per piece for segment-by-segment placement along the weld joint
• Ceramic construction withstands weld pool temperatures without contaminating the root bead
• Eliminates back-gouging and back-welding on qualifying single-sided joint designs
• 24 pieces per box for consistent jobsite inventory management

Compatibility

Designed for use as ceramic weld backing on single-sided groove welds in structural steel and fabrication applications where a 75-degree triangle backing profile is required by the joint design or welding procedure specification.

Installation Notes

Ceramic weld backing is applied by qualified welders or weld technicians following an approved welding procedure specification (WPS). Backing strips are typically secured to the reverse side of the joint using adhesive tape supplied separately before welding begins. Ensure the base metal is clean, dry, and free of mill scale, oil, and moisture at the joint area prior to backing placement. Follow all applicable AWS structural welding code requirements for joint fit-up and backing strip continuity.
