Mega Industries four-corner sprayarc argon® welding process is performed in precision fixtures on WR430 through WR2300. This ensures the highest quality waveguide, which is mechanically stable and designed for optimum electrical performance. We exceed EIA , IEC and Mil standards for both rectangular waveguide (IEC 60153-2, EIA RS-261, MIL-DTL-85 ) and cover flanges (IEC 60154-2, EIA RS-166, EIA RS-271, MIL-DTL-3922). Our standard models are commercial grade and military grade. For more information, please contact Mega Sales.
