Title:
金属部材の加熱方法、加熱した金属部材の接合方法、及び金属部材の加熱装置
Document Type and Number:
Japanese Patent JP6690270
Kind Code:
B2
Abstract:
To provide a heating method for a metal member, a junction method for a heated metal member, and a heating apparatus for a metal member. A heating method includes an oxide film formation step S110 and a heating step S120, where the film thickness [alpha] of an oxide film is set to a first range Ar1 including a first maximal film thickness A corresponding to a first maximal value a with the film thickness of an oxide film OM exceeding zero to make an absorption coefficient emerge as a maximal value at first and a second maximal film thickness B corresponding to a second maximal value b to make an absorption coefficient emerge as a maximal value at next, in the relation with an absorption coefficient having periodicity, and where the absorption coefficient is smaller than a second minimal film thickness BB corresponding to a second minimal value bb with the film thickness to make an absorption coefficient emerge as a minimal value, between the second maximal value b and a third minimal large film thickness C corresponding to a third maximal value c to make an absorption coefficient emerge as a maximal value at next to the second maximal value b.
