Abstract
PURPOSE: To prevent the occurrence of cracking in weld metal by welding the underlayer of welding in such a manner that the carbon content in the weld metal becomes less than the specific amount and welding an upper layer thereon in build- up welding of iron, steel or cast iron of the specific carbon contents.
CONSTITUTION: A groove 2 is formed in the damaged portion produced in the base metal 1 of iron, steel or cast iron of 1.3wt% or more and 2.4wt% or less in carbon content. Thence, the base metal is build-up-welded with the underlayer 3 of build- up welding by using an automatic welding machine and mild steel or low-alloy steel welding material in such a manner that the carbon content in its weld metal becomes 0.7wt% or less. Thence, the upper layer 4 of build-up welding composed of the specific composition is build-up welded on the underlayer 3 of build-up welding. These obviate the occurrence of cracking in the weld metal even if the build-up welding is done automatically on the rolling roller or adamite roll roller of high carbon contents.
