OK 92.60
 
The Last Word in Cast Iron Welding
OK Selectrode 92.60 is latest development in cast iron welding. With a specially designed slag it can weld extremely difficult to weld cast irons, in all positions. The refining action of the slag prevents hot shortness in high sulphur cast iron, giving a sound radiographic joint.
 
The weld deposit produced has exceptional strength over those created by run-of-the-mill cast iron electrodes. For repairing thick joints in cast iron it provides fail-proof performance and prolonged service life.
 
It can also be used for radiographic quality joints between cast iron and stainless steel / mild steel / manganese steel / Inconel alloys.
 
ALLOY BASE
Ni, Fe, Mn
 
SPECIAL FEATURES
  • High quality joints in any critical cast iron repairs
  • Nitrogenous slag gives clean inclusion-free joint
APPLICATION
OK Selectrode 92.60 is applicable for any cast iron application - joining buffering and surfacing. Applications involving high joint strength and fatigue in service condition should be welded only with this grade.
 
PROPERTIES
UTS : 56-61 kg / mm2
 
WELDING PROCEDURE
  • Clean the weld area of all scales, rust, grease and dirt
  • Use the smallest possible electrode diameter
  • OK Selectrode 92.60 has high current capacity, so for big jobs use sufficient current for proper base metal fusion and bonding
  • One may use skip welding sequp.nce to limit the heating of the base metal
  • Although preheating is not required in most cases, when welding complicated castings preheat to about 250 - 300°C to minimize the shrinkage stresses generated in the base metal
  • Just after welding peen the joint lightly with ball pen hammer and cool slowly
CURRENT RANGE : (AC 50, DC+/-)
 
Size (mm) Length (mm) Current Range (Amp)
3.25 350 75-150
4.00 350 90-175
