Abstract. Recent years have seen a lot of research on modern steels with higher yield strengths. The study investigates the microstructure and mechanical properties of two different welding techniques - gas metal arc (GMA) and laser beam (LB). The result of this study showed a significant softening effect in the heat-affected zone (HAZ) for both welding techniques, the GMA and LB, resulting from formation of a coarse-grained microstructure during welding. The findings of this study increased understanding and added to the body of knowledge in the rapidly growing field of GMA and LB welding processes of HSLA steels.

Abstract. Modern mechanical constructions consist of purchased elements and workshop-made elements. Undoubtedly, purchased components – made in specialized factories – have a definite advantage in quality and durability. Unfortunately, sometimes the operating parameters of a component for a given application are insufficient. Then it remains to design and manufacture a given element in the workshop – losing quality and costs. This paper presents a different approach. Application requirements can be customized just include an additional (simple) element, e.g. a force amplifier, and a purchased component can be used.

Abstract. This paper is devoted to the safety of mountaineering systems, which are designed to prevent falls from a height. The purpose of the paper is to investigate the safety of fall arrest systems and their effectiveness. In addition, the study is to answer the question of whether mountaineering systems are used in the industrial area. This area requires the use of different mountaineering systems than in the case of sport mountaineering. As parks at heights are included in the list of particularly dangerous works, an analysis of systems protecting employees against falling from a height was undertaken. For this purpose, surveys were conducted to determine their correct operation and the degree of employee protection. Employees working in the profession of industrial mountaineer were defined as the research group. As a result of the conducted research, it is determined that employees use individual and collective protection measures. Respondents declared that the means they use work correctly and determine high effectiveness of protection against falls from a height. The systems themselves are built in the correct way and the respondents did not clearly indicate one dominant disadvantage of the mountaineering systems they use.

Abstract. Spatial diversity of the natural environment can be presented using raster qualitative data. They can be the result of collecting field data or be the result of stochastic modelling of a certain complexity of the environment. One example of such modelling is the determination of similar elements of relief forms on the basis of morphometric variables. The use of unsupervised methods for clustering raster data in modelling can produce different maps. It is necessary to assess the compatibility of the obtained maps in order to assess how significant the differences between them are. The article presents selected stochastic and deterministic methods for assessing the spatial distribution of data. Exemplary methods of measuring variability at the global and local level were discussed.

Abstract: The article presents two methodologies for testing the effectiveness of camouflaging military equipment. The tested objects were camouflaged with deforming camouflage dedicated to the environment and season. The tests covered the visible spectrum and were carried out both in real conditions - training ground, and in a virtual environment – on a specially prepared calibrated stand, characterized by compliance with real conditions and human perception of vision – presented colors, as well as in terms of the amount of information and detail rendering. These two test methods were compared, attention was drawn to the high correlation of results and to some characteristic properties of both separately. The work confirms the legitimacy of developing and improving virtual research methods as supporting in the design and testing of modern camouflage patterns, especially at the initial stage of pattern design. It can also be useful when assessing masking systems in other ranges of electromagnetic radiation: UV, near infrared, or thermal range.

Abstract. One of the most often utilized metals in a variety of industries is aluminium alloy. Secondary aluminium alloys have drawn a lot of interest in recent years. Scrap aluminium may be recycled, which is good for the environment. In addition, compared to primary aluminium, it produces at a lower cost due to its lower energy requirement. Because it adversely affects their characteristics, secondary aluminium alloys' higher iron concentration presents the most frequent challenge. Manganese can be added to reduce its impact to some level. The objective of this research is to improve our knowledge of how iron and manganese affect the fatigue resistance of secondary aluminium alloys. Four alloys with various iron and manganese concentrations were tested to determine this impact.

Abstract. Nowadays, organizations continuously compete with each other and other market competitors. It is clearly visible in paper production market in Poland which is constantly developing taking over even the plastic product market due to the regulation of the reduction of the impact of certain plastic products. Therefore, for a single company there is a need to search and take competitive advantage. In order to build competitiveness it is possible to refer to improvement of quality process which can lead to additional benefits for organizations or customers. It can concern various aspects of the company such as structures, processes, activities or products. The aim of this paper is to propose methods and tools of quality management at particular stages of paper production process to build or improve market competitiveness in paper industry.

Abstract. For the analysis of the quality of metallurgical products, it is important to use techniques that identify the internal and external unconformity of the product without destroying it. These techniques are non-destructive testing (NDT). Although these techniques identify the unconformity of the product, they do not indicate the source of their creation. The purpose of the study was to develop a hybrid method to make decisions about the causes of product incompatibility. This hybrid method was created as a combination of NDT and quality management techniques, i.e.: 5W2H method, Ishikawa diagram, 5Why method. The subject of the study was an unconformity detected in the tube made of the magnesium alloy AMS 4439. Research was carried out using the FPI method. In the analyzed case, its application allowed the detection of a linear indication in the product. To identify the root of the linear indication, the 5W2H method, the Ishikawa diagram, and the 5Why method were used sequentially. The main causes were bad casting and pollution. The root cause was defective supplier material. Integration of the FPI method, the 5W2H method, the Ishikawa diagram, and the 5Why method in the performance of a comprehensive qualitative analyze of products, after which it is possible to identify the unconformity and the root of its occurrence. The integration of FPI and quality management techniques can be practiced to analyze the quality of products (including metallurgical products) in manufacturing and service enterprises.

Abstract. Computational data processing often poses significant challenges for individuals not professionally specialized in this area. In particular, the problem lies in finding suitable computational tools that, on the one hand, have the necessary functionalities and, on the other hand, are easy to use for users with intermediate or low-level competencies. During the academic year 2022/2023, the Faculty of Mechanical Engineering at the Cracow University of Technology conducted classes on data processing for three diverse groups: the third- and fourth-year students of a public high school with a math-physics-computer science profile, undergraduate students in safety engineering, and undergraduate students in applied informatics. The needs regarding the functionalities of the computational tools and the competencies in their usage were compared, both in the assessment of the instructors and the participants themselves. The article presents comparisons of computational tools in terms of various aspects, as well as guidelines for their application for each target group.
