Evaluation of Welded Joints of Automotive Sheets

Abstract:

Currently, the laser technology are used a broad-spectrum in combination with modern computer technology, especially in the field of engineering, energetics, electronics, medicine and the military. In engineering laser technologies record in coupling with robotization allowing five dimensional movements the biggest development mainly in the automotive industry. The most commonly are used for the heat processing of materials, cutting and in particular welding. The technology of laser welding is used in various industries. The thermal cycle at laser welding is usually faster than conventional arc technologies that lead to the small widths of welds and heat affected zones. To satisfy of difficult requirements of current time by this technology, it has to constantly develop and progress. Therefore, it is necessary to evaluate the quality of made products and thus to guide the production in direction towards improving their resulting properties. The paper is focused on the evaluation of mechanical properties, metallography and measurement of microhardness of automobile body sheets connected by laser welding.
