The United Musical Instruments' (UMI) brasswind plant in Eastlake, OH, are making brass instruments using plasma arc welding (PAW) technology. The PAW machines weld 150-200 instruments a day using Alloy 360 yellow brass, red brass, nickel-silver and other sensitive materials, with metal thicknesses 0.018-0.028 in and tolerances as close as one-fifth of a thousandths of an inch. Using argon gas, no filler material, keeping control of heat and water cooling throughout, an operator welds a radial butt joint connecting brass horn bells to the stem tubing, all while carefully monitoring welding speed, which averages 3 in/min.
