Establishments primarily engaged in manufacturing metal forming machine tools, not supported in the hands of an operator while in use, for pressing, hammering, extruding, shearing, die-casting, or otherwise forming metal into shape. This industry also includes the rebuilding of such machine tools and the manufacture of repair parts for them. Establishments primarily engaged in the manufacture of electric and gas welding equipment and soldering equipment are classified in Industry 3548; those manufacturing portable power-driven handtools are classified in Industry 3546; and those manufacturing rolling mill machinery and equipment are classified in Industry 3547.
