<p><P>PROBLEM TO BE SOLVED: To provide a method for joining dissimilar materials which suppresses influence on property (characteristic) at a steel material side and obtains a joining part having high joining strength by spot welding without excessively increasing production cost of a steel material. <P>SOLUTION: The method is used for joining dissimilar materials of the steel material with a specified composition and a 6000 series aluminum alloy material by spot welding. Aqueous glass is preliminarily coated on a joining surface at the steel material side and is forcedly dried before the spot welding, and the spot welding is carried out under conditions of specified pressurizing force between electrodes, electric current between the electrodes, and energization period. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
