TERROWELD CLH
 
Buffer for Oil Soaked & Dirty Cast Iron
A cast iron welding electrode for operation at low heat input depositing a non-machinable weld. The electrode is recommended for buttering of oily, greasy, and dirty cast iron to avoid contamination in the fi nal welding. It is suitable for non-critical welding in cast iron with high preheat.
 
It is also suitable for welding in deep holes and tight corners for all types of sections giving good colour matching as the deposit oxidizes in a similar fashion.
 
ALLOY BASE
Fe, Mn, Si
 
SPECIAL FEATURES
  • Spray type deposit insensitive to contamination
  • Good colour match
  • Can be used in final layer to give hardness and wear resistance
APPLICATIONS
Pump housing, machine casing, rotor bodies, cast frames & cover, gear box, flywheel, oil soaked castings, ash pipes, oxidized cast iron furnace equipment, discs, etc.
