A ball for laundry ball is provided consisting of two symmetric semi-spherical halves, a pair of annular plates and an inner porous armor to retain a plurality of washed solid particles within the same. The porous armor can easily be displaced in these two halves when they are assembled and are fixed between them by those annular rings to construct a washing ball by means of supersonic welding. The free end of the halves is provided with a connector edge, which has a plurality of positionally spaced apart holes. One of the annular rings is provided with a plurality of mounting pins that correspond to the positioned holes of the edges and connectors. Each one of the mounting pins can be received and retained within the positioned hole and are welded to another annular ring by means of supersonic welding.
