Abstract
A pointed wire-shaped filling material made of aluminium is utilized to contact the point at a position of an aluminium mould to be repaired. The wire-shaped filling material is charged with a current in order to melt the point of the filling material and form an arc which melts the mould at the position of repair. The filling material is then pressed into the mould at the position to be repaired. Upon filling the repair point, the wire-shaped filling material is cut close to the surface of the mould to complete the repairing process.
