JOINING METHOD AND DEVICE THEREFOR

摘要

A joining method, which comprises an initial washing step (S1) of washing the surface of articles (1b, 2a) to be joined, to remove a material (G) interfering with joining, such as an oxide or an adsorbed material, a surface roughness controlling step (S3) of forming an uneven surface having a prescribed roughness on one joining face (1b), a surface treatment step (S5) of removing a re-adsorbed material (F) attached to joining faces (1b, 2a), and then pressing a joining face (1b) having the uneven surface formed above to another joining face (2a), to thereby join the articles. The above joining method allows the metal joining at an ordinary temperature under a condition of an atmospheric pressure.
