Suppose I have two cubes of the same material, say gold for example. Suppose the pieces are each single crystal, with the same crystal orientations relative to the surfaces of the cubes. Let us also suppose the surfaces are very flat. If I now clean any oxides off the surfaces, and bring two surfaces together,why won't the two gold cubes link together and become a single solid? Shouldn't mutual attraction between atoms at surface of each cube pull the solid together?
Re: Why is welding necessary? Why don't atoms on surface of solids link up?
