Abstract
It is useful to join micro/nano materials with Joule heat because the melting and the following solidification at the contact of materials occur in self-completed manner. By the way, it is very important to join dissimilar metals for producing high quality micro/nano mechanical systems. In this paper, we join dissimilar-metal wires with Joule heat and measure the current for joining. By comparing the current for joining dissimilar-metal wires and that for cutting the wires, we investigate the condition for welding dissimilar-metal wires with Joule heat.
