Research of a laser welding of thin-shit construction steels by continuous laser radiation

Abstract

© 2019 IOP Publishing Ltd. All rights reserved. The results of the laser welding by continuous radiation of thin-sheet low-carbon steels on the example of steel 08U presented in this paper. Metallographic studies of the laser weld were conducted. Tensile tests were carried out as a result of which it was determined that the nature of the fracture is adhesive, and after cohesive failure of the specimens, it is show the high quality of the welded joints at the beginning of the weld.
