Abstract
A method of manufacturing a metal product comprise forming a base region on a surface of a metal member by repeatedly scanning along a predetermined first direction while irradiating the surface of the metal member with a base laser beam over a first set of rows. The method further comprises forming a marking by repeatedly scanning along a predetermined second direction while irradiating the surface of the metal member with a marking laser beam over a second set of rows. The second direction is different from the first direction. An identification code having a predetermined pattern comprises a combination of the base region and the marking.
Claims20
A method of manufacturing a metal product, the method comprising:
- forming a base region on a surface of a metal member by repeatedly scanning along a predetermined first direction while irradiating the surface of the metal member with a base laser beam over a first set of adjacent rows;
- and
- forming a marking by repeatedly scanning along a predetermined second direction while irradiating the surface of the metal member with a marking laser beam over a second set of adjacent rows,
- wherein the second direction is different from the first direction, and
- wherein an identification code having a predetermined pattern comprises a combination of the base region and the marking.
A metal product comprising:
- an identification code having a predetermined pattern comprising with a combination of a base region and a marking formed on a surface of a metal member,
- wherein the base region comprises multiple rows of adjacent first laser grooves extending along a predetermined first direction, and
- wherein the marking comprises multiple rows of adjacent second laser grooves extending along a predetermined second direction which intersects the first direction.
A metal product comprising:
- a metal member;
- and
- an identification code having a predetermined pattern comprising a combination of a base region and a marking formed on a surface of the metal member,
- wherein the base region comprises multiple rows of adjacent first laser grooves extending along a predetermined first direction, each of the first laser grooves being formed by a plurality of pulse marks lying one upon another in a row along the first direction, and
- wherein the marking comprises multiple rows of adjacent second laser grooves extending along a predetermined second direction different from the first direction, each of the second laser grooves being formed by a plurality of pulse marks lying one upon another in a row along the second direction.
