Abstract
A method of joining dissimilar materials of the present invention has a step of lapping a high melting point material on a low melting point material with a third material interposed therebetween. The third material is different from the high and low melting point materials. Further, the method has a step of irradiating an energy beam onto the high melting point material and a step of pressing the high and low melting point materials to cause eutectic melting between at least one of the high and low melting point materials and the third material and to join the high and low melting point materials in the form of a line.
Claims10
A method of joining dissimilar materials, comprising:
- laminating a high melting point material on a low melting point material with a third material interposed therebetween, the low melting point material having a melting point lower than that of the high melting point material, the third material being different from the high and low melting point materials;
- and
- irradiating an energy beam onto the high melting point material and then pressing the high and low melting point materials to cause eutectic melting between at least one of the high and low melting point materials and the third material to join the high and low melting point materials in the form of a line.
