Sif Super Silicon No 9 is a new welding rod in the Sifbronze range for oxy-acetylene welding of cast iron, developed by Weldability-SIF. Designed for full fusion welding, the rod provides a machined high-strength weld metal and a good color match with the same structure as grey cast iron. Offered in 4mm, 6mm and 10mm diameter 1m rods, the rod is square in section and available in 1kg and 5kg packets. The rod is suitable for the welding and joining of castings found in general manufacturing, agricultural and construction industries. It can be used for welding cast iron to high alloy steel or cast iron to Mn steel plates. It can also be used to build up and repair worn, broken or damaged areas, as well as surfacing of new castings. Provided the surface area to be welded has been ground and angled to a fine point, this rod can be used for TIG welding.
