Opis:
This paper focuses on the weldability of advanced high-strength steels (AHSS), commonly used by the automotive industry and civil engineering. These steels have found application in the construction of mobile platforms mounted on vehicles. AHSS significantly outperform other materials when it comes to performance flexibility and mass reduction potential. This article verifies whether the application of micro-jet cooling technology during the welding process might help to overcome these issues. The aim of this article is to choose welding parameters in the process with micro-jet cooling to obtain the best mechanical properties of the welded structure (elongation). The best welding parameters for these difficult-to-weld constructions are presented in detail.

Opis:
This paper examines the possibility to improve mixed weldability of pins to mobile platforms. There is an increasing demand for mixed joints made of hard-weldable steel used in civil engineering and the automotive industry. A good example of this is welding of movable platform elements such as a pin to arm joints. The pin is very often made of yield structural steel S690 QL (1.8928), while the arm of the movable platform is mainly made of DOCOL 1400M steel from the AHSS group (advanced high-strength steel). This kind of joint is not easy to manufacture due to the different chemical compositions and thicknesses of both grades of steel. The difference in the thickness of welded elements creates an additional difficulty. The main aim of this article is to determine the most appropriate welding parameters and select additional materials to obtain the correct joint with good mechanical properties, free from welding defects and incompatibilities. This article examines whether the application of micro-jet cooling technology during the welding process might help to overcome these issues. For the first time, micro-jet cooling was not used to weld these grades of steel. The welding parameters and the micro-jet cooling parameters were investigated.

Opis:
Purpose: Checking the quality of a joint made with a newly developed method. Design/methodology/approach: A new welding method has been developed in order to obtain a high-quality joint. The properties of the joint were checked by NDT (Non Destructive test) tests and the strength and fatigue strength were tested. Findings: Now, adding to the shielding gas mixture can improve the quality and properties of the weld. Research limitations/implications: In the future, it can be suggested to investigate the effect of nitrogen in other gaseous shielding mixtures of the MAG welding process. Practical implications: The proposed innovation will not cause problems in the production process. Only the shielding gas will be modified without affecting the technological process, management and economic aspects. Social implications: Modifying the welding method will not affect the environment and production management methods. Originality/value: What is new is to propose a new solution with its scientific justification. The article is addressed to manufacturers of structures made of HSS and AHSS steels.

Opis:
Klęski humanitarne to nieodłączny element życia na Ziemi. Z powodu różnych katastrof, naturalnych i powodowanych przez człowieka, w których budynki ulegają zniszczeniu, mieszkańcy terenów zurbanizowanych zmuszeni są niejednokrotnie do zamieszkiwania w odległych od swych dotychczasowych domostw miejscach. Ideą projektu było przeprowadzenie prac badawczo-projektowych mających na celu opracowanie kontenera nowej generacji, który mógłby być multiplikowany w sposób wertykalny, przybierać różne funkcje, być budowany i rozbierany przez samych użytkowników, składać sięw pewnych swych częściach z materiałów biodegradowalnych, w innych na tyle lekkich i wytrzymałych, by wykorzystać je wielokrotnie (zgodnie z ideą gospodarki obiegu zamkniętego - gospodarki cyrkularnej).
Humanitarian disasters are an integral part of life on Earth. Due to various disasters, natural and man-made, in which buildings are destroyed, residents of urban areas are often forced to live in locations far away from their existing homes. The intention of the authors was to conduct research and design work to develop a new generation container, that could be multiplied in a vertical way, take on different functions, be built and taken apart by its users, be composed of biodegradable materials in some parts, and in other parts be light and durable enough to be reused many times (in accordance with the idea of circular economy).

Opis:
The development of a technology that increases the service life of valve seats in CNG/LNG-powered vehicles requires the appropriate selection of material and the technology of its application. Commercially used valve seat materials show accelerated wear under operating conditions, especially in natural gas vehicle engines. The authors developed a new material concept and a new technological concept for the protection of the valve seat in CNG/LNG-powered vehicles. This article aims to present the first stage of tribological research. Two materials were used in the research: Stellite 6 alloy and Fe3Al intermetal. A commonly used material for valve seats of combustion engines is Stellite 6. The Fe3Al is the new proposed material coating for the protection of the valve seats of internal combustion engines. This article compares the abrasive wear resistance of these materials. The abrasion tests were performed on a T-11 pin-on-disc tester, and the counter-sample was steel S235JR. The test conditions were similar to those prevailing during the operation of the valves in the head of the internal combustion engine, without the influence of temperature. The obtained results indicate that the Fe3Al intermetal is characterized by a lower coefficient of friction and lower wear intensity than Stellite 6. The results confirm that the Fe3Al phase is a prospective material to be used as a protective material on the valve seat of vehicles.

The paper presents the possibilities of using light alloy components in vehicle construction. Material 6082 was chosen for use in responsible structural components. The structure and strength parameters of the material in the delivery state were tested. Tested material parameters were compared with normative requirements. The purpose of the paper is to check the mechanical properties of aluminum alloy welded joints by various processes and parameters. Until now, welding of 6082 alloy did not give good and repeatable results. Because of that, two welding methods were analyzed (MIG and TIG) in the field of the quality of welds, strength of welded joints, and material structures obtained as a result of welding with various parameters.

Opis:
Aluminium alloys were used in many structural applications, including the civil engineering field. The innovative technology of welding with micro-jet cooling was tested and the effects were reported. The main information is given on the parameters of aluminum welding with the micro-jet cooling process. Information was also reported on the influence of various micro-jet parameters on the metallographic structure. Subsequently, metallographic and certain physical properties of welding structures (for example, mechanical resistance, electrical conductivity) were tested. Aluminum alloys are lightweight and resistant to corrosion in the natural and aquatic environment, which is why they are a suitable material for responsible structures (in the construction of ships, vehicles, electrical conductors). This article focuses on the mechanical and electrical properties of busduct welds made with the micro-jet cooling pioneering technology.
Stopy aluminium były wykorzystywane i zastosowane w wielu konstrukcjach, w tym dla potrzeb inżynierii lądowej. Przetestowano innowacyjną technologię spawania z chłodzeniem mikro-strumieniowym i przedstawiono wyniki badań. Główne informacje dotyczą parametrów spawania aluminium z chłodzeniem mikro-strumieniowym. Podano również informacje o wpływie różnych parametrów chłodzenia mikro-strumieniowego na strukturę stopiwa. Sprawdzono strukturę spoin i pewne właściwości fizyczne złączy spawalniczych (na przykład wytrzymałość na rozciąganie i przewodność elektryczną). Stopy aluminium są lekkie i odporne na korozję w środowisku naturalnym i wodnym, dlatego są odpowiednim materiałem na odpowiedzialne konstrukcje (w budowie statków, pojazdów, szynoprzewodów). W tym artykule skupiono się na właściwościach mechanicznych i elektrycznych spoin szynoprzewodów wykonanych z użyciem pionierskiej metody chłodzenia mikro-strumieniowego.

Opis:
The paper focuses on modern martensitic steel (Docol 1200M) and its joint manufactured by means of welding process supported by micro-jet cooling for special vehicles’ structures. Docol 1200M is a type of material denoted as AHSS (A- advanced; H - high; S – strength; S - steel) with important material characteristics, which allows the potential to reduce the weight of the construction of transport means. The paper verifies if the use of micro-jet cooling after MAG welding process could help to maintain initial mechanical parameters of special vehicles’ components. The quality of the joining process was checked by nondestructive and destructive tests. Results from tensile tests have enabled capturing the stress-strain curve as well as mechanical parameters and comparison with data of the parent material. Fatigue properties of the weld are described in terms of the fatigue limit and fatigue diagram, presenting fatigue limit as a key mechanical parameter with respect to the application of the joint examined. Testing the fatigue strength of a new steel grade for special vehicles’ structures in the innovative MAG process at micro-jet cooling was treated as the main goal of the study.

Opis:
Stainless steel could be treated as the main material used to construct various means of transport, including mobile platforms and tank trucks. An austenitic steel known as 316L steel (1.4401) has high resistance to atmospheric corrosion, natural waters, water vapor, alkaline solutions, and acids, even at elevated temperatures. This steel is weldable, although it is also prone to various types of welding cracks. Many factors influence the quality and mechanical properties of a joint. The most significant of these is the appropriate selection of welding parameters, which should be determined precisely and separately for each type of sheet, depending on its thickness and geometric features. The aim of the present article is to study the influence of main TIG (Tungsten inert gas) welding parameters on the creation of proper joints used in the construction of mobile truck platforms or tank trucks. The proper selection of parameters enables the production of welds with good functional properties. A novelty of this article is the proposal to weld each layer of a thick joint with different parameters, which has an important influence on the mechanical properties of the joint. It is expected that the new material and technological solution will yield a joint with good corrosion resistance and increased mechanical properties. This is important in the responsible construction of means of transport, using the example of mobile platforms and tank trucks. Different tests verifying the properties of joints, including non-destructive testing, tensile strength tests, and fatigue tests, as well as a hardness probe, were applied.

Purpose: The aim of the study is to find out whether and to extent the change of selected parameters of the system, such as the type of tires, tire pressure and axle load, changes the result of the technical test of the analysed vehicle in the field of measuring braking forces. Design/methodology/approach: Diagnostic tests, tire pressure measurements, axle load measurements, braking force measurements on a roller device were carried out. Findings: The relationships between the pressure in the tires and the braking force measured on the wheel as well as between the braking force and the load acting on the vehicle axle have been demonstrated. Research limitations/implications: Mathematical relationships between tire pressure and vehicle braking force can be derived in the future. Practical implications: In the course of the tests, it was found that the technical tests made it possible to determine the braking forces only while maintaining the nominal ±1×105 Pa tire pressure. Changes to this parameter may influence the measurement results. Moreover, the influence of tire pressure on the change of the measured braking force values was found, which translates into the safety of the vehicle in road traffic. Originality/value: approach to brake system.

In recent years, the development of IT systems for fleet monitoring was observed. Tire pressure monitoring systems are constantly improved. Decreased values in tire pressure can cause deformation of tires. Monitoring of tire pressure is an important function in oversized transport trucks. Tire pressure and rolling resistant influence fuel consumption. The purpose of this paper was to determine the impact of tire pressure on fuel consumption in a fleet of trucks with tire pressure monitoring system installed and to determine the impact of other factors that may affect fuel consumption, such as the vehicle weight, brake usage and cruise control usage. The results of the research were developed using a multiple regression model describing the above dependence.
