7.3 Characterization of Ultrasonically Spot Welded Tecanat GF 20

7.3.1 Ultrasonically Spot Welded Lap Joints

The ultrasonically spot welded lap joints of Tecanat GF20 were characterized experimentally with a tensile lap shear test (based on ASTM 3164) and an impact test (based on ASTM 950) to assess their load bearing capacity. For impact testing, the lap joints used were unconventional without notches or other modifications to create stress concentrations to reduce the amount of material for each sample (Fig. 7.3).
