1   Scope

  This part of [IEC 60352](/search?q=IEC%C2%A060352)
   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](/search?q=IEC%C2%A060228)) 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.
