which is stronger?
(OP)
when building a structure from tubular material, would the use of bends in continuous piece be stronger and more rigid than the same angle being made out of two straight pieces welded together? Assuming a good mandrel bend(outside radius stretched, inside radius commpressed)opposed to a large radius weld. The material is 4130 .083 thick.-thanks

Bending: cold working adds strength
welding: welds often are not perfect
The thichness limits bend radius

The two options should be considered for a design and fabrication veiw point since the there is little difference in the weld strenght.
