I just measured the thickness change at the melted area. The average thickness in the non melted areas is .075inches and in the melted area it is down to .062 inches so it lost almost 18% thickness which is the cause of the severe pulsing that was experienced after the melting. Close examination does not reveal any delamination between the steel and aluminum.
