Problems of the behaviour of all-steel, laser welded sandwich panels in plate-to-web contact zone are presented. Results of laboratory tests on determination of deformation field around laser weld under bending load - obtained by laser interferometry technique - are shown. Analysis of strain field distribution is included and same conclusions related to modeling of behaviour of such connection are drawn.
