Thin-walled cold-formed steel (CFS) offers many advantages over traditional
materials for structural applications including light weight, high-strength and
stiffness, dimensional stability, durable and non-combustible nature, energy
efficiency, recyclable nature, and structurally optimal shapes. The objective of
this study was to explore joining methods for cold-formed steel structures
including laser joining and friction stir welding. The processing methods used
and the resulting microstructure, mechanical and corrosion behavior will be
presented. The resulting defect density processing was correlated with the
manufacturing parameters. In addition, joining of dissimilar steel and aluminum
structures was also explored and the joints were characterized to understand
structure-property relationships.
