EN ISO CODE:
A low heat input, Ni-Cu alloy (Monel) type electrode for machinable welding of cast iron.
LoTherme-702 is a nickel-copper alloy electrode for low heat input welding of cast iron without preheating. The welds are sound, strong and easily machinable. The electrode displays a soft and steady arc, which is easy to strike and re-strike and ability to operate on low currents.
LoTherme-702 is suited for joining of broken cast iron parts, repairing defects in cast iron foundry and repairs of fractured iron parts in all welding positions. Typical applications include rebuilding of worn out surface, gear teeth, pump impellers, etc.
Ultimate Tensile Strength : 335 MPa
Weld Metal Hardness : 160 BHN
Re-dry the electrode at 150°C for one hour before use. Clean the base material thoroughly free of any surface contamination. Use short weld runs followed by peening. In case of repair welding on castings, remove entire defective portion to sound metal prior to welding.
