Title:
BUILD-UP METHOD
Document Type and Number:
Japanese Patent JP2009012056
Kind Code:
A
Abstract:
To provide a build-up method by which in the case of build-up working each valve-seat part in a cylinder head, the development of crack into the build-up layer caused by a heat transmission from the other valve seat part is prevented and also, the strain of the cylinder head is reduced.
Since the build-up orders of respective valve seat parts 1-8, 1a-8a, are set so that the heat input of laser beam to the valve seat part built up at the number (n) is not transmitted into the valve seat part buit up at the number (n+1), the development of the crack to the build-up part of each valve seat part 1-8 and 1a-8a, is prevented and also, the strain of the cylinder head 10 can be reduced.
