The study discussed in the article aimed to compare the high-performance robotic MAG TANDEM process with the partly mechanised MAG STANDARD process. Experimental tests involved comparisons concerning the heat effect of the dual-electrode MAG TANDEM process with that accompanying the single-electrode MAG STANDARD process. The tests also included comparisons of linear welding energy (heat input) and...
The study presents possible savings resulting from the use of deep-penetration welding processes in the fabrication of welded structures. The study-related tests revealed 80% savings of filler metals and the 50% reduction of welding distortions without compromising the maximum load-carrying capacity of welded joints. The tests involved steel grades S355J2, S460NL, S700MC, S690QL and 450HBW (Hardox)...
The study presents the geometry as well as results of the peeling, shearing and metallographic tests of copper and aluminium welded joints used in the absorber panels of flat solar collectors. The article discusses desired characteristics and mechanical properties of ultrasonic welded joints and compares the latter with laser welded joints. In addition, the study indicates prospective implementation...
