OK 92.58
 
Strength Welding for all Cast Irons
OK Selectrode 92.58 is a new generation alloy electrode for welding and repairing of malleable and grey cast irons, and difficult-to-weld cast irons viz. S.G. iron.
 
The weldmetal is machinable, possesses high strength coupled with good toughness, thus making it suitable for joining cast iron to steels and filling-up cavities in castings.
 
ALLOY BASE
Ni, Fe, Mn, Si
 
SPECIAL FEATURES
  • Smooth bead consists of fine ripples
  • Excellent slag peel-off
APPLICATIONS
Joining of cast iron components, welding of cast iron to steels, rectification and build-up of defective castings giving good colour match. Repairing of complicated and crack sensitive castings involving hydrostatic pressure and dissimilar thickness, heavy sections and joints under restraint such as pumps, differential housings, cast iron dies, etc. Other applications are cast iron gears and pulleys, sliding tables for machine tools, cylinder blocks.
 
PROPERTIES
UTS : 44-47 kg / mm2
 
WELDING PROCEDURE
  • Clean the weld area of all scales, grease and dirt
  • The smallest possible electrode diameter and the lowest possible current should be used
  • Skip welding sequence may be used to limit the heating of the base metal
  • Although mostly preheating is not required, when welding thick sections and malleable irons, preheating to about 250 - 300°C is advisable to minimize the shrinkage stresses and cracking
  • Just after welding the joint can be lightly peened and should be allowed to cool slowly
CURRENT RANGE : (AC 50, DC+/-)
 
Size (mm) Length (mm) Current Range (Amp)
3.20 350 60-120
4.00 350 90-150
