Use of acoustic emission in the evaluation of corrosion resistance of CMT welds

Popis výsledku v původním jazyce

The objective of this paper was to investigate and respond to the quality and strength of CMT welds that were subjected to degradation effects and subsequently to tensile testing. The tensile test was recorded using AE acoustic emission. The experiment focused on the quality of CMT welds (Cold Metal Transfer) and the resistance of these welds to corrosion degradation. Welds are generally exposed to environmental influences such as high stress, stress and degradation effects. The combined effect of these factors may in some cases result in the destruction of weld joints. For this reason, emphasis is placed on the quality of welds and their resistance to environmental influences. For this measurement there were ten samples prepared, divided into two groups, each having five samples. One group was subjected to corrosion degradation, while the other one was at the same time subjected only to environmental influences. Subsequently, all samples were subjected to tensile testing. The course of this test was recorded using the AE acoustic emission, where the AE sensor was attached to each weldment to record dislocations during the tensile test. Named values were evaluated in the Dakel-Daeshow program.
