There is more to this than what meets the eye.
Most trailer frames are "cambered".
Haven't heard the term cambered, but from your description it sound like they are inducing stresses into the beam (pre stressing) by putting weld beads down. Never seen it done that way.
Inducing stress into the metal it a very common process, typically achieved by other means (think of it has a heat treatment, typically done on high carbon content steel).
I will look for signs of such 'cambering' (I would expect to see it on top of the beam or upper flange)?
