A&P Southampton and its engineering division - Helifusion, have announced that they have recently achieved Lloyds Register certification for a new weld process to supplement their existing class approved process Fleetfusion. The Fleetfusion spiral welding process originated in 1979 as a result of demand from the M.o.D for a cost effective repair for Hydroplane shafts on submarines, this process has served Helifusion well for many years and will continue in certain applications. Utilising the M.I.G. welding system however has its limitations in that the maximum deposition is 2.5mm per run thus inter run machining is required for multiple layer build ups.
