TL;DR: In this paper, a high-performance controlled short-circuiting metal transfer process at a wire feed rate of 12m/min for wire arc additive manufacturing (WAAM) with an Al-Mg-Mn alloying system was developed.

TL;DR: In this paper, the main breakdown products that influence the current waveform are oxygen and carbon monoxide, and the main coatings breakdown products are polyacrylate, polyvinyl butyral, epoxy zinc filled, vinyl chloride, vinyl isobutyl, and organosilicate coatings.

TL;DR: In this paper, a finite element model was developed to determine the temperature distribution in the preheating phase of the friction surfacing (FS) process, where the variable parameters were the axial force and the speed of rotation of the consumable rod.

TL;DR: In this paper, a comparison of porosity evaluation methods was held using the sample of welded-brazed zinc coated steel and Al-Mg-alloy plates joint.

Abstract: On the basis of arc metal deposition process the technology for carbon nanotubes (CNT) addition to metal was developed. It uses extruded metal rods with CNT’s as additional material. For this study the developed technology was used for modification of metal Al-5Mg alloy. Comparison of macroand microstructure for metal obtained with developed technology with CNT’s and without it shows no strong difference for modified and not modified metal. Nevertheless CNT’s were observed in modified metal with use of SEM and analysis of microhardness showed that addition of CNT increases microhardness in upper layers of deposited metal.
