Set up and operate machines to fabricate ornamental metal products.
Operates friction-welding machine to join metal components, according to work orders, specification tables, and diagrams: Installs, aligns, and adjusts fixtures and stops, using handtools and precision measuring devices, such as micrometers, calipers, verniers, and gauges. Positions parts to be welded into rotating and stationary cylinders of machine holding devices and aligns cylinders in parallel position, using wrench. Turns knobs to regulate speed and timing of rotating cycle and pressure force of stationary cylinder. Presses button to activate machine motor and depresses pedal to start friction-welding cycle to perform trial run. Removes welded parts from machine, using wrench. Periodically inspects workpieces, using precision measuring devices. May perform maintenance operations before and after machine functioning, such as greasing machine, adjusting tension of drive belts, and maintaining specified level of hydraulic fluids and coolants.
