The polymer is molten due to the heat transfer between both materials, penetrates the surface of the metal joining partner and thus wets it.
Despite the complete overlap, both materials are not in full contact.
The effect is detectable for all investigated materials but depends on a corresponding melt volume and the temperature distribution.
