Title:
HEATING METHOD FOR METAL MEMBER, JUNCTION METHOD FOR HEATED METAL MEMBER, AND HEATING APPARATUS FOR METAL MEMBER
Document Type and Number:
Japanese Patent JP2017074620
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a heating method for a metal member that enables the stable and high-efficient heating of a metal member by improving the absorption coefficient of laser beams with a thin oxide film capable of being formed at low cost, a junction method for a heated metal member, and a heating apparatus for a metal member.SOLUTION: A heating method includes an oxide film formation step S110 and a heating step S120, where the film thickness α 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.SELECTED DRAWING: Figure 1
