<p>PURPOSE:To enhance tenacity, in the damping structure of a railroad or the like, by constructing a welded, structure using a thick damping metal plate wherein a zeolite type damping material is held between metal plates and subsequently subjecting said structure to stress removing annealing. CONSTITUTION:Thick damping metal plates each formed by bonding a zeolite type damping material 2 between thick metal plates 1, 1a such as steel plates under pressure by a hot press are welded at welding parts to construct a welded structure which is, in turn, subjected to stress removing annealing. By this method, the stress removing annealing of the welded structure using thick plates as structural members can be certainly performed and the welded structure excellent in tenacity can be stably formed.</p> |
