Abstract
The present invention is a fusion-bonded product having a high-strength part, comprising: a first preform () constituted by integrally, frictionally pressure-welding a first low-carbon steel part (L) made of low-carbon steel containing less than 0.45% of C and a high-carbon steel part (H) made of high-carbon steel containing not less than 0.45% of C; and a second preform () having a second low-carbon steel part (L) made of second low-carbon steel containing less than 0.45% of C; wherein the high-carbon steel part (H) of the first preform () is provided with a high-strength part () that has been previously formed into a desired shape and quenched, the second low-carbon steel part (L) of the second preform () has been previously formed into a predetermined shape, and the first low-carbon steel part (L) of the first preform () and the second low-carbon steel part (L) of the second preform () are bonded to each other by fusion welding.
