Laser opto-acoustic and thermal-wave techniques have been applied for investigation of metals structure modification after laser and electric-arc welding. The changes in granular structure of steels due to welding have been considered. Anisotropy of thermal-conductivity due to thermal-induced stress in the heat-affected zone of laser weld seam has been obtained.
