Copper plated, seamless metal cored wire for hardfacing. Very high resistance to wear caused by the abrasive action of minerals, clay, sand, gravel, … Well suited for wear resisting parts subject to heavy impact and shock, the molten pool is easily controlled and the beads are smooth.
The absence of slag allows welding in several layers, without the necessity to remove the slag.
The deposited metal is crack-resistant, also after several layers.
The coppered wire is hermetically sealed and does not absorb moisture, not even after longer storage periods.
Mechanical spades, bulldozers, scrapers, crushing hammers, bucket and loader teeth, conveyors, crusher jaws, crusher cones, etc.
Hardness: 55 - 65 HRC.
The coppered seamless wire can be welded with standard driving wheels but for smaller types of driving wheels the serrated wheels for tubular wire can work better.
Mixed gas Ar-CO2 at about 12 litres a minute.
The interpass temperature should be maximum 250 °C.
The weld metal requires no buffer layer except on materials considered critical.
In this situation, Lastifil 20 TB or Lastifil 8070 is to be used as a buffer.
The weld metal is machinable by carbide tools, hardening is possible.
