Tasneem Gul Kazi et al.

Summary: Research indicates that welders are exposed to higher concentrations of manganese and chromium in welding fumes compared to control subjects. The prevalence of anemia and stomach disorders is higher in adolescent welders, while asthma is more common in adult welders. Neurological issues are particularly observed in welders over 50 years old due to long-term exposure to toxic substances, especially manganese, in poorly ventilated workshops.

Process Stability, Microstructure and Mechanical Properties of Underwater Submerged-Arc Welded Steel

Maofu Zhang et al.

Summary: By adding water glass in underwater wet welding, the penetration of welds can be effectively increased and the frequency of arc extinction can be reduced. Despite the higher porosity, the comprehensive mechanical properties of the joints were not significantly improved. The application of epoxy resin to isolate water from the welding area greatly enhanced process stability, leading to an increase in elongation and impact toughness compared to underwater wet welding, as well as achieving a bending angle of 180 degrees in the joint.

Porphyridium purpureum microalga physiological and ultrastructural changes under copper intoxication

Zhanna Markina et al.

Summary: The study assessed the effect of copper on cell dynamics and structure of the microalga Porphyridium purpureum. Results showed that Cu inhibited population growth at 150 μg/L, increased chlorophyll a fluorescence at 100 μg/L, and enhanced phycoerythrin fluorescence at 150 μg/L. Furthermore, the content of ROS increased with increasing Cu concentration in a dose-dependent manner.

MATHEMATICAL ANALYSIS OF THE INFLUENCE OF THE FLUX-CORED WIRE CHEMICAL COMPOSITION ON THE ELECTRICAL PARAMETERS AND QUALITY IN THE UNDERWATER WET CUTTING

S. Parshin et al.

Summary: The research in the field of underwater wet cutting using flux-cored wires has led to the development of gas and slag systems, and determination of optimal parameters for cutting stability and quality. The underwater wet cutting mechanism involves cyclic formation of periodic keyholes in metal and can be analyzed based on cycle times, welding current, voltage, power, and short circuits for efficiency assessment. The authors also developed a method for analyzing oscillograms to calculate the probability density of current, voltage, and power to assess stability and efficiency.
