1 Scope
This part of IEC 60352
covers ultrasonically welded connections and includes requirements, tests and practical
guidance information.
This document covers ultrasonically welded connections made with stranded or flexible
wires (class 2, 5 or 6 per IEC 60228) of copper or copper alloy, as well as of aluminium or aluminium alloy.
These welded metal-to-metal connections shall employ wires with cross-sectional area
of 0,08 mm 2 to 160 mm 2 and shall not exceed a total cross-sectional area, in case of wire bundle, of 200
mm 2 .
For aluminium or aluminium alloy wires, the minimum required cross-sectional area
is 2,5 mm 2 .
Additionally, information on materials, data from industrial experience and test procedures
are included to ensure electrically stable connections under prescribed environmental
conditions.
Lastly, this document aims to achieve comparable results when using ultrasonic welding equipment with similar performance and specifications as specified by the termination
manufacturer.
NOTE Figures in this document show examples of possible solutions of ultrasonically welded
connections of rectangular shape, but solutions are not restricted to the shape displayed.
