- Abstract
Comparative analysis of the structure and mechanical properties of welded joints of large-diameter pipes with wall thickness 30 mm produced commercially by submerged arc welding and by combination of the latter with hybrid laser-arc welding is performed. The results of impact tests and the data of fractographic studies are used to infer that that the combined welding process is more advantageous.
