Single-side full penetration welding is the primary welding process in shipbuilding. This process requires the use of a backing to support the molten metal. Conventionally, copper has been used as the backing material in the shop and ceramic tiles for jobs on the field. However, copper has shown to contaminate the weld and produce adverse effects and ceramics have shown to produce porosities in the weld. A new backing with an intermetallic layer (NiAl) on the copper surface has been fabricated. The results indicate that this backing could alleviate the contamination problems and produce quality welds.
