A specially formulated low-heat input 70/30 alloy for Cupro- Nickel welding.
LoTherme-536 is a copper - nickel electrode, for joining and surfacing of wrought and cast alloys of similar composition as well as 80/20 and 90/10 alloys. It operates in all conventional positions.
LoTherme-536 is used in offshore applications because of its good resistance to the corrosion in seawater. It is also suitable for shipbuilding, chemical process equipments, oil refineries, food industries, etc.
ULTIMATE TENSILE STRENGTH : 40 Kgf/mm2
ELONGATION (L=4d) : 28 %
Clean the weld zone thoroughly. Wall thickness in excess of 5 mm must be grooved out with a 90°V. Bigger work-pieces are preheated to about 200-250°C. To avoid overheating, guide the electrode vertically at high welding speed. Use only dry electrodes. Electrodes that have got damp must be dried 2 to 3 hours at 250°C.
