Process of joining similar metals with the application of heat and with or without the application of pressure.. While welding the edges of metal pieces are either melted or brought into plastic condition.. Corrosion. The iron in steel corrodes easily to form iron (II) oxide. Sodium metal reacts quickly to form sodium oxide. The copper roof of the parliament building corrodes to form copper carbonate. Tarnished silverware forms silver sulfide. The pores can be sealed (closed-cell foam), or they can form an interconnected network (open-cell foam).. The defining characteristic of metal foams is a very high porosity: typically 75-95% of the volume consists of void spaces..
