Title: Welding method of plating material

Abstract: In  method  for  spot-welding,  a  spot-welding  process  is characterized by making holes in substrate for evaporating plating solutions and then welding the substrate to another  substrate  in order to reduce contact area with plating solutions. In the  above method, as the increase of perforated area  in  substrate  reduces the contact area between bracket and bottom cover, it can  protect plating substrate from inclusion of  plating  solutions  into  gap between bracket and bottom cover. And it can prevent plated  metal which is welded by this method from corrosion by residual  plating solutions.
