Abstract
The results of development and testing of hybrid laser-arc welding of large-diameter pipes are given. The main results of the research, in particular, on the peculiarities of weld formation in different regions of circumferential joints, mechanical properties of the welded joints, and potentialities of the available equipment for construction of main pipelines are generalized.
