Founded in 1977 by metallurgist Alan Flash, Cerbaco Ltd. designs and manufactures non-metallic weld backings for full-penetration, finished-quality welds from one side. The Warrington company combines engineered formulations with hands-on technical assistance, creating custom shapes, sizes, and even new formulations when a welding application calls for something different. Cerbaco has worked with welding engineers around the world to address difficult fit-ups and inaccessible joint backs.
