Aluminium Bronze electrode for sea water corrosion resistance.
LoTherme-534 possesses outstanding welding properties and can be used in all positions, except vertical down. The weld metal displays high mechanical properties and is tough, pore-less and not prone to cracking.
LoTherme-534 is used for joining and surfacing on aluminium- bronzes (up to 10% Al), copper and copper alloys as well as surfacing on steel, cast steel and cast iron. It is also suitable for welding pipe cavities in new aluminium-bronze castings. Its corrosion resistance allows it to be used on marine propellers, acid pumps and fittings.
Ultimate Tensile Strength : 450 MPa
Elongation (L=4d) : 20 %
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 150-250°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.
