Beam fabricating device

An I-beam fabrication device used to hold and weld two distinct T-shaped beam portions in a preshaped curved configuration, the beam fabricating device comprises a pair of vertically spaced support members defining a beam receiving area therebetween, a plurality of movable arm assemblies positioned on each of the vertical spaced support members, a plurality of guide rail support brackets secured to each of said vertical spaced support members, guide rails on said support brackets, means for activating said arm assemblies into engagement with a beam portion to clamp said beam portion against said guide rails, means for defining a predetermined curved configuration of said beam portions and means for supporting and bending said beam portions into said predetermined curved configuration, means for maintaining vertical alignment between said guide rails, means for adjustably positioning said beam portions within said receiving area to adapt to a variety of beam portion widths, and welding means movably positioned on one of said vertical support members.
