Nanofoil is a new nano–material and is made up of thousands of alternating nanoscale foils, which can be used in welding process. When nanofoil is applied in welding, firstly, the nanofoil is activated by a small energy pulse from electricity, light or heat sources, and then the temperature can be increased to about one thousand degrees in a fraction of a second.
