Purpose: The paper is focused on experimental verification of weldability of high-carbon steel C55E processed by the SPD DRECE (Dual Rolling Equal Channel Extrusion) process. Design/methodology/approach: A test of basic mechanical properties, metallographic examination and an analysis of residual stresses were performed on these joints. Findings: Acquired results show that the choice of an appropriate technology and the optimization of welding parameters allow to achieve solid welds even in the case of materials rather difficult to weld. The optimized welding process does not significantly degrade the properties acquired by SPD. Research limitations/implications: Mastering a proper coupling technology, welding materials after plastic deformation in particular, is one of key parameters for a successful application of given materials in technical practice. Within experimental works, test welded joints were made from the C55E steel with the use of 141-GTAW pulse welding technologies. Originality/value: The methods of intensive plastic deformation SPD (Severe Plastic Deformation) belong to a group of very attractive means of increasing utility properties of metallic materials (strength and structural characteristics).
