Hybrid Metal Extrusion & Bonding (HYB) is a new solid state joining technique that uses filler material addition and plastic deformation to create sound joints. The filler material addition makes the HYB process more flexible and less vulnerable to weld defects compared to conventional solid state joining techniques. Moreover, the operational temperature during processing is even lower than that reported for conventional joining techniques, which reduces the width of the heat affected zone (HAZ) significantly as well as residual stresses and contaminants in the weld zone. Here we report the joining of the dissimilar materials aluminum alloy 6082-T6 and structural steel 355. The joint is found to be free from defects like pores and internal cavities and is fully characterized herein from a metallurgical point of view.
