en iso 14700: t fe8 welding positions:
features benefits applications
? superior hardness as a result of special ? well suited for wear resisting parts subject to ? automatic and mechanized welding
carbides heavy impact and shock, as well as abrasion ? bucket and loader teeth
? good reignition characteristics ? surface remains free of cracks ? conveyors
? virtually no slag coverage ? no re-drying ? crusher jaws and cones
? smooth arc characteristic ? suitable for robot applications
? weld metal machinable only by grinding ? welding without shielding gas possible
? a buffer layer is recommended for critical
materials or multi-layer build up
wire type gas shielded metal-cored wire
shielding gas 75-85% argon (ar)/balance carbon dioxide (co2); welding without shielding gas possible
gas !ow 12-18 l/min
type of current direct current electrode positive (dcep)
standard diameters ? 1.6 mm (1/16?)
re-drying not required due to seamless wire design
storage the same conditions as for solid wire. product should be stored in a dry, enclosed
environment, in its original undamaged packaging
weld metal analysis (%) (typical values for mixed gas 82% ar / 18% co2 )
carbon (c) 1.3 nickel (ni) -
manganese (mn) 0.8 molybdenum (mo) -
silicon (si) 1.4
chromium (cr) 6.5
niobium (nb) 6.5
hardness of pure weld metal from the 3rd layer (typical values for mixed gas 82% ar / 18% co2 )
hardness rockwell (hrc) 56 - 64
the achieved hardness as well as the structure of the hardfacing depends
on (among others): base material, welding parameters, working and
interpass temperature, heating up, cooling down, number of layers,
hardfacing methods and shape of component
