EFFECT OF HEAT INPUT DURING DISK LASER BEAD-ON-PLATE WELDING OF THERMOMECHANICALLY ROLLED STEEL ON PENETRATION CHARACTERISTICS AND POROSITY FORMATION IN THE WELD METAL

The paper presents a detailed analysis of the influence of heat input during laser bead-on-plate welding of 5.0 mm thick plates of S700MC steel by modern Disk laser on the mechanism of steel penetration, shape and mens tee depth of penetration, and also on tendency to weld porosity formation.Based on the investigations performed in a wide range of

In agriculture, new and sustainable strategies are increasingly demanded to integrate the traditional management of viral diseases based on the use of virus-free propagation materials and resistant or tolerant cultivars and on the control of insect vectors.Among the possible Integrated Pest Management (IPM) approaches, organic biostimulants have sh
