Abstract
This paper presents the comparison results of laser and arc welding methods. The modes for laser welding, hybrid laser-arc welding and laser welding with filler wire for the St3 plates with the thickness of 10 mm were developed. Three test joints were welded by each welding method using the developed modes. The metallographic studies were conducted demonstrating stable formation of the welded joint and absence of internal defects. The residual deformations were assessed for the following types of welding: laser welding, hybrid laser-arc welding, laser welding with filler wire, single-sided and double-sided manual arc welding, single-sided and double-sided mechanized welding in the active gases and mixtures. The test samples for each welding type were analyzed in terms of the level of residual deformations after welding by comparing geometric dimensions and using the 3D scanning procedure. A comparative technical and economic analysis of welding methods was performed.
