LoTherme-635B

It is specially designed for surfacing of dies and tools in forging industries.

CHARACTERSTICS
  • LoTherme-635B is a low heat input, all conventional position electrodes depositing Cr-Ni-Mo-V-Co alloy. Balance of ltoughness and hardness with control chemistry.
  • The electrode gives soft & smooth arc which is easy to strike & lre-strike.
  • Superior operating characteristics with easy slag detachability.
  • The welds are of radiographic quality.
  • It has got superior deformation resistance at high temperatures.
Applications :
  • It is specially designed for surfacing of dies and tools in forging lindustries.
  • For repairs of large hot working dies, drop forging industry, punches and inserts by filling out of shape for further machining to get desired profiles.
WELD METAL HARDNESS:

First Layer : 34-36 RC

Third Layer : 37-40 RC

Welding Technique :

Re-dry the electrode at 250-300 C for one hour before use. Use low current, short arc and stringer beads. Preheat the job up to 400 C with slow cooling to eliminate the hot cracking.

Current Conditions : DC (+) / AC
