In a machine boom, one of the adjacent blocks has one of the upper and lower or left and right side walls protruding longer than the other side wall, and the inside of the other side wall has a longer longitudinal wall than the other side wall. A protruding lining wall is provided, and the other adjacent block has one short side wall and the remaining long side wall respectively abutting the side wall of the one block, and the long side wall of the other block is abutted against the side wall of the one block. A boom for construction machinery characterized by fitting onto the outer surface of the lining wall of the blocks to abut adjacent blocks, and welding these abutting side walls to each other.
