LASER TREATMENT OF A HEAT-AFFECTED ZONE AFTER ARC WELDING OF CONSRUCTIONAL STEELS
The change of structure in a heat-affected zone of low-alloyed constructional steels after laser processing is considered. The influence of technological parameters of laser processing on structural changes of the investigated steels is determined. The factors influencing the change of mechanical properties and strength characteristics of materials depending on the depth of penetration of the laser radiation are shown.
