Abstract
The aim of each engineer is to achieve the elimination of impact of welding technology on defects in the welding joint, resulting in weld joints of the required quality. The achieving of this goal allows for a modern welding technique that attempts to meet ever-increasing demands. This article is focused on the comparison of the welding quality created by metal active gas and shielded metal arc welding. In the introduction part, the article describes the researches on the subject presented in the world over the last period. The second part of the article is devoted to the description of materials and methods used in two experiments. In each of the experiments, five samples were subjected to non-destructive testing by a capillary method and an ultrasound method, followed by metallographic samples, which confirmed the results and detailed the welding joint to obtain a comprehensive picture of the defect. The final part of the experiment presents the Vickers Hardness Testing of created welds. The last part of the article describes the overall evaluation of achieved results.
