Mechanical Properties of Metal Expansion Joint Manufactured by Mechanically Assisted Laser Forming

Abstract. The presented article describes the general principle of operation of metal expansion joint (MEJ) manufactured by mechanically assisted laser forming. These details are important elements designed to compensate for temperature differences and limitations of construction materials. The authors described and analyzed the traditional method of producing metal expansion joints and drew attention to its limitations and potential problems. This work mainly focused on strength tests. The resistance of the MEJ to tensile forces was tested. The rest of the article presents the results of strength tests of the proposed method of hybrid production of MEJ. The authors focused mainly on the recorded parameters of the testing machine and the stretching process. The results are presented in graphs. The results of the tests confirmed that the proposed method is effective and efficient, enabling precise control of the production process of metal expansion joints.
