Cast Iron Electrode - ELFER

Standards

Chemical Composition of Weld Metal % (Typical)

Typical Base Material Grades

• Repair of welding defects for facing of worn out parts of mold of automobile body, shielding process of metal frictioning works.
• Good results at joint welding of steel with cast iron.
• Basic coated, Barium compound free, iron based, Vanadium alloyed cast iron electrode which is used for repairing and maintanance of defective lameller and nodular cast iron equipment and machine parts. Also used for hard face welding of wear suspectible of cast iron parts Adventages of this Nickel free cast iron electrode is;
• The deposit metal is a close color match to cast iron.
• The similaritiy of chemical composition of wed metal and cast iron assures similar that expansion and contraction charactheristics, as a result there is no subject about thermal deformation.

Features and Applications

• When welding electrode is not hot, as a result welding can be done uninterrupted and more quickly
• Consumables of this alloy type are used as covered electrodes and as tubular cored electrodes.
• The core rod and the tube respectively consist of unalloyed steel.
• The covering and the core respectively contain carbide-producing elements.
• By welding of cast iron, the microstructure of the first layer will be ferritic with much carbide.
• As carbon combines with the carbide-producing elements, too much hardening by formation of martensite is avoided.
• Preferred application: Surfacing of grey and nodular cast irons and malleable cast irons. Buffer layers on aged cast irons will produce a good fusion to the parent metal.
