The investigation addresses the over-all performance of dissimilar joints of low carbon steel and stainless steel thin sheets achieved by laser hybrid welding. First, the technological de-velopment of dissimilar laser hybrid welding of thin sheets is briefly pre-sented. Joint characterisation by means of macro and microstructural examination and hardness tests is fur-ther described. Microhardness testing was used as an alternative and effi-cient mean of assessing the changes in mechanical properties of difficult to characterize areas, like HAZ and fu-sion zone of these thin sheets Laser-GMA dissimilar welded joints. The overall tensile performance of the joint is discussed together with the weld metal strength overmatching. The ten-sile tests results indicate that in case of transversally loaded joints, the po-sitive difference in yield strength between the weld metal and the base materials (overmatching welds) may reduce the weight of the structure, without diminishing its strength.
