| Popis: | In the paper are presented the tests carried out on the specimens made of boot laser welded joints of high strength ferritic steel S960QC. The tensile properties materials for materials the weld, heat affect zone and base of welded joints were determined. For verification of strength welded joints during tensile test and registration of the strain fields created during joint loading used the optical video system Aramis. On the basis of strains, and using the true strain-stress dependencies, the stresses in the weld material and in the base material at the area of the occurrence of strain localization were determined. |
