I was giving some thought of how to bind two metals together without using any heat or welding wires/rods and an idea struck me. Seeing that the atoms are similar to each other why not excite them using a frequency that would be applied to make them energetic enough to just bond together? If a sound frequency could be found that could make the atoms so energetic couldn't this actually be done? Just a thought, what's your thinking along this line?
