(JP10044246-A)      Two thermoplastics parts (20, 30) are connected by fusion welding using an electric heating wire (40) which is positioned between them, the parts being urged towards one another while an electric current, sufficient to heat the surrounding plastics to fusion temperature, is passed through the wire by electrodes which contact the wire through access apertures (25) provided on one part, and are withdrawn after fusion of the two parts.    The resulting part is claimed.    USE -   In joining a cover (30) to a casing (40) after parts, such as a battery, have been assembled in the casing.    ADVANTAGE -   Provides a casing in which the heating wire is completely enclosed within the body of the assembly, and which can be easily sealed to prevent ingress of liquids or contaminants.
