Certain embodiments disclosed herein relate generally to fabrication of structural beams. More specifically, certain embodiment disclosed herein related generally to securing together the components of structural beams.
Structural beams come in a wide variety of forms. The form of a structural beam may be determined by a set of variables that may comprise the geometry of the beam and the material of the beam.
One method of fabrication of structural beams comprises welding together two or more components of structural beams. In some embodiments, the components of the structural beam may comprise a web and a flange. In some embodiments, the web and the flange may be joined together by a joining operation to form a beam.
Many materials undergo dimensional change in response to temperature change. Dimensional change in response to temperature change may also be known as thermal strain. Without limitation, some materials expand when heated and contract when cooled.
A joining operation may comprise heating of one or more components to be joined. In some joining processes, the component may have its temperatures changed dramatically from the temperature to which the component will be subjected to during normal use. In some joining processes one component or one part of the component may be heated or have its temperature changed unevenly with respect to other parts of the same component or other components. Uneven heating can result in uneven thermal strain or thermal distortion.
In some operations, uneven thermal strain of a component may result in unacceptable product quality, or may result in additional undesirable manufacturing cost or time. In some joining operations thermal strain of a component during or after joining operations may not be negligible and may result in unacceptable product quality, or may result in additional undesirable manufacturing cost or time. In some operations, uneven thermal strain or thermal distortion may result in unacceptable bending or warpage of the finished beam.
It remains desirable to provide methods of securing the components of beams so that uneven strain or distortion of the beam during or after joining operations, does not result in unacceptable product quality and does not result undesirable additional manufacturing cost or time.
