thus maintaining the rebar ductility based on experimentation using argon co 2 shielding gas with the 90 10 ratio and at approximately 35 cfh flow rate obtains the strongest fusion rebar weld a rebar panel containing a plurality of such fusion welds is inherently strong and self stabilizing thus the fusion welded rebar panels do not require any additional stabilizing structure to maintain panel integrity an independent testing facility was employed to examine the strength value of the weld and to examine the overall effect of the weld on the structural integrity of the rebar the conclusions reached by researchers at the independent testing facility are presented in appendix a and incorporated by reference herein the present invention anticipates a variety of alternative embodiments of the welded rebar manufacturing center without deviating from the scope of the present invention fig4 discloses a portable welded rebar panel manufacturing center 40 made in accordance with the present invention the portable welded rebar panel manufacturing center is mounted on a movable vehicle such as a trailer but otherwise includes the same components as described above namely rebar shear 12 rebar bender 14 welding jig 16 rebar welder 18 power source 20 and one or more rolling tables 22 the portable manufacturing center is designed to be transported to a construction job site for manufacture of rebar panels of various sizes this portable version of the invention is especially useful for producing large welded rebar panels that are difficult to transport intact from remote manufacturing facilities using existing technology in addition the portable manufacturing center is useful when especially complex panels are required in the construction process an alternative embodiment is shown with reference to fig5 7 which disclose a stationary welded rebar panel manufacturing center 50 fig5 discloses a building.
