- ItemVliv svařovacího procesu na deformační chování oblasti bodového svarového spoje(Technická Univerzita v Liberci, 2009) Rys, Jaroslav; Neumann, HeinzThe aim of this theses was to suggest methodic suitable for research of deformation behaviour of weld joint zone. Theoretical part describes technology of resistive dot welding, basic relations used for calculation of welding parameters and resistance during passing of electric current throught materials. Further it deals with welding parameters and quality of weld. Also particular types of steel used in automotive industry are described in this part. Practical part contains results of micro rigidity measuring in dot joint zone and results of metallography on optical microscope. In the second part, deformation behaviour was examined with ARAMIS instrument on material DOCOL 1200.
