Abstract
The experiments on development of techniques of multipass hybrid laser and laser-arc welding of pipe steels are described. Structure of produced joints, as well as their impact toughness and corrosion resistance were investigated. Rationality of further developments of appropriate technological processes for application of mentioned methods of welding to extend the service life of pipeline transport is shown.
