OK 92.58
SMAW
Type Basic-special high graphite

A nickel-iron-cored electrode for producing high strength welds when joining normal grades of cast iron, such as grey, ductile and malleable irons. The weld deposit has good ductility and is machineable.

OK 92.58 is recommended for the reclamation of faulty/damaged castings and the joining of castings to all cast or composite fabrications. Typical components are machine bases, engine blocks, gears and transmission housings.Deposition is performed on cold or slightly preheated cast iron. The weld metal is stronger and more resistant to impurities than the nickel-cored type.

When welding cast iron without preheat, the smallest electrode diameter and the lowest current should be used in order to limit the width of the heat affected zone. When welding thick sections and malleable irons, preheating to about 300C is advisable to minimise shrinkage stresses and cracking. During welding the joint can be lightly peened and on completion the workpiece should be allowed to cool slowly.
