VIBRATION WELDING METHOD FOR MANUFACTURING MANIFOLD FOR FUEL CELL

摘要

PURPOSE: A vibration welding method for manufacturing manifolds for fuel cells is provided to prevent the following deformation after welding of manifolds by pressing the top and bottom of the manifold during vibration welding. CONSTITUTION: A vibration welding method for manufacturing manifolds for fuel cells is as follows. When vibration-welding a plurality of individual manifolds(110,111,112) in contact with each other, following deformation positions of the individual manifolds are predicted. The individual manifolds corresponding to the predicted positions are pressed from the top and bottom and vibration-welded.
