My friend has 200 used hospital beds that have 2 pieces of angle iron each (about 6' long after removing the ends). Off hand I believe this angle is about 1.25" x 1.25" x 1/8". It is that type of iron that is next to impossible to drill. Harder than heck. But not brittle (yet). My friend has hopes of using this angle to fabricate trusses to span 32 feet. Using 1/4" plate gussets to hold the trusses together. Each top and bottom chord will have a minumum of two angles with the gusset sandwiched between. Legs (no longer than 30") in compression will have a 'stabilizer' in the middle. At not time will a bead be placed across the angles. All beads will be on the long edges. Is there any safe way to weld this hard angle to the hot rolled plate brackets?
