Abstract
A clad welding method, which can prevent the occurrence of incomplete fusion, and can cover the surface of a base material over a wide range with a weld metal, while suppressing the dilution of the weld metal, by use of a relatively simple technique, is provided. For this purpose, a welding heat input is increased at a location where one end () of a preceding weld bead () and the other end () of a succeeding weld bead () overlap, as compared with a welding heat input at a location where the preceding weld bead () and the succeeding weld bead () do not overlap, to produce a deep penetration portion () involving locally deep penetration ().
