Abstract

In the paper we present the analysis of the hardness (HV₁₀) in more directions in transverse area of the joint, in the thermal-influenced area (TIA), in the basic metal (BM) and in weld, but we also analyze the embrittlement and stubcracking effect and the angle at static bending. The hardness analysis of melted material and also the study of embrittlementand stub-cracking effect and the analysis of static bending angle under constant load offer very important information over the quality of welded joints and their behavior when exploiting them.

Keywords
