The Gas Fusion Welding Process

Cast Iron Welding Services weld cast iron using gas fusion welding. This ensures a homogeneous stress free weld repair with improved metallurgical and machining properties compared to those of the parent metal. All castings are pre-heated at a controlled rate until the optimum welding temperature is reached. Whilst the entire component is maintained at this temperature, the area to be repaired is then subject to the application of intense localised heat bringing it to a fluid state.

The welding operative maintains a molten pool of the base metal into which is fed a carefully selected, own manufacture, cast iron filler material of the same grade. Controlled cooling from the fluid state to ambient temperature ensures a stress free homogeneous weld repair. Classification Society Approved – Work carries a twelve month warranty.
