SOFTWELD® 55 Ni (ENiFe-CI)

A versatile, all-purpose electrode for repairing and reclaiming gray cast iron. It is recommended for repairing heavy sections and phosphorous bearing castings. Welds made with this electrode are strong and ductile. Multi-pass welds are typically machinable. Operational characteristics are excellent.

SOFTWELD® 99 Ni (ENi-CI)

A high nickel electrode specifically recommended for applications where machinability is important. Even single pass welds are machinable.

It is recommended for surfacing applications and repairing small casting defects when the deposit will require machining.

FERROWELD® (ESt)

A low cost steel electrode for repairing cast iron. It is recommended for repairing pits and small cracks in castings. The deposits are not machinable but may be finished

The serviceability of a product or structure utilizing this type of information is and must be the sole respon- sibility of the builder/user. Many variables beyond the control of The Lincoln Electric Company affect the results obtained in applying this type of information. These variables include, but are not limited to, weld- ing procedure, plate chemistry and temperature, weldment design, fabrication methods and service re- quirements.

ALUMINWELD® 43 (E4043)

An extruded electrode for both metallic arc and carbon arc welding aluminum plate. The dense high strength welds can be polished leaving practically no discoloration. The molten flux retards oxidation and dissolves excess aluminum oxide to produce high quality deposits.

GUIDELINES FOR WELDING CAST IRON

The majority of cast iron parts are gray cast iron. These guidelines are limited to welding this material. Because of its hard and brittle structure, welding white cast iron is generally impractical. Malleable, nodular, and other heat treated types of cast iron usually require heat treat-

ing after welding to restore the strength and ductility requirements to the part. Although they can be welded, the special procedures and heat treating required makes repair welding these materials expensive.

How to Locate Cracks - A simple but effective way of locating surface cracks is to use commercial dye penetrant methods. As an alternate, you can swab the damaged area with a kerosene soaked rag to remove grease and dust. Immediately chalk over the area with common
