EN 14700: T Cu1
• Special cored wire for GMAW
• The weld metal is a Cu - Mn - Ni - Al bronze
• Weld deposit resists the combined effects of corrosion, erosion and cavitation
• Sound, pore free deposits on ferrous and non-ferrous base materials
The building up of aluminium bronze, cladding components undergoing metal to metal wear under high pressure. Especially suited for marine environments.
The addition of nickel improves corrosion resistance in heat and rough seawater. Excellent resistance to cavitation and stress corrosion cracking.
Examples
Heat exchanger elements for sea-water desalination equipment, bearings, valves, gears etc.
Boat propeller castings as specified in American specifications Mil-B-21230-A

Stringer or weaved beads
Can be welded gun leading or gun trailing
The use of pulsed current is recommended for improved wetting and bead appearance
Higher currents and voltages can be used, but cause increased element burn-off (particularly Al) and dilution, leading to lower hardness levels.
