“…The protective gas flow rate has its most suitable range in the welding process. When the protective gas flow rate is increased to support the molten pool, it will inevitably affect the weld morphology and plasma temperature [14,15]. In addition, the problems of narrow process windows, poor adaptability to misalignment and butt gap in overhead welding have yet to be effectively addressed.…”

During overhead welding, gravity inevitably drives the molten pool downward, resulting in poor adaptability and concave defect. To address this issue, this paper proposed a novel laser-MAG hybrid overhead welding technique utilising a copper liner (COL). Compared to single-arc welding, laser-MAG hybrid welding can reduce the volume of the molten pool, while the laser increases its support force. The COL can accelerate the molten pool's solidification rate. Additionally, the adhesion force between the molten pool and the COL can partially counterbalance gravity. As a result, good weld formation still was achieved even when the misalignment was 0-1 mm and the butt gap was 0-2 mm. Moreover, the back reinforcement height and width were not less than 0.71 and 3.66 mm, respectively.

“…[1,2] Thus, these pollutants affect the density and structural composition of the soil, and their accumulation leads to an ecological imbalance that adversely affects the environment. [3,4,5] Purpose of the study: to assess the ecological state of soils in the territories exposed to technogenic pollution near the ash dump of the thermal power plant.…”

This work evaluates the state of the soil that has undergone negative changes as a result of technogenic impacts, the presence of pollutants -heavy metals, considers the assessment of the state of the soil by the bioindication method. Shell amoebae, which are unicellular organisms, as well as earthworms and plants, were used as bioindicators. We also studied the ratio of the concentration of heavy metals in the soil to the distance of these soils from the source of heavy metals, and the seasonal dynamics of changes in the content of heavy metals in the soil. Using the method of stripping voltammetry, results were obtained on the presence of heavy metals in soil, earthworms and plants.
