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.

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.

The austenitic 316L steel (1.4401) is an important stainless material used to build various means of transport. Austenitic steel has high resistance to atmospheric corrosion. The austenitic steel is treated as a good weldable material, although cracks are possible. This paper analyses the influence of various MIG welding parameters on the creation of correct joints used in the stainless steel structures of mobile platforms elements, as an example of welding structures, in various means of transport. Various tests verifying the mechanical properties of MIG welds, including non-destructive tests, tensile strength and hardness tests, were carried out. This article aims to show how important and complex the task is to select the correct welding parameters for elements of means of transport made of austenitic steel on the example of elements of mobile platforms.

Opis:
Telecommunication, transport and civil engineering play an important role in new research areas. New antennas based on innovative materials are being developed. At the same time, the methods of antenna mounting with the use of high-strength materials to ensure high structural rigidity with the lowest possible weight are being planned. These materials include AHSS steels with ultimate tensile strength (UTS) up to 1700 MPa and elevated yield point (YS); however, welded joints made of these steels have much worse mechanical properties, compared to the native materials. In this paper, it was planned to test the MAG welding of DOCOL 1400M steel (AHSS group). Directly after welding, a micro-jet joint cooling was applied. It was determined to create thin-walled joints that could be used in the formation of antenna mounts.

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:
Advanced high-strength steel (AHSS) is being used increasingly often in the structure of means of transport. Welds made of these steels can crack in the heat-affected zone (HAZ) and have inferior mechanical properties compared to the base material. The goal of this paper was to solve the technological and material problem of obtaining highstrengh thin-walled welded structures of AHSS steel designed for heavily loaded elements of transport means. The novelty of the article is its presentation of a modified welding process which enables a high-strength structure of the obtained joint to be obtained without welding defects and incompatibilities. Copper backing was selected as an effective method of heat dissipation in the process, and, using the basic solutions method, the leverage of a heat flow process in the weld method deposit (WMD) was checked after cooling down the substrate. The fundamental solutions method was used to determine the optimal shape of the backing. It has been shown that the new backing affects the structure and mechanical properties of welds. In order to verify the newly developed method, tensile tests of the obtained joint were carried out, the hardness was assessed, the metallographic structure was analyzed, and non-destructive tests were performed. The developed material and technological solution were used, for example, for the construction of the arm element of the mobile platform.

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 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:
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:
Both the processes of welding and stamping are becoming increasingly more common in the construction of means of transport. Heavily loaded vehicle components should have good plastic properties so that cracks do not occur under operating conditions. Welded joints often crack, especially when they are subjected to additional treatments, such as stamping. In this article, the possibility of MAG welding (Metal Active Gas) of low-alloy steel using (MJC) micro-jet cooling was checked. Then, the made joints were subjected to a stamping test. Weld metal deposit (WMD) was carried out for the classic MAG process and compared with the modern method using MJC. Joint sand stamping tests of low-carbon and low-alloy steel were carried out. Welding with micro-jet-cooling could be considered promising due to the useful structure of WMD. This structure yields better mechanical properties, i.e. higher impact toughness for subzero service. For the first time, it was decided to check the pressure of the sheets welded with an innovative welding process. Then, the samples obtained by welding were subjected to the process of stamping. The result of stamping of welded sheets was investigated. The results of stamping show that only after correct welding process might the expected mechanical properties be achieved.

Opis:
Various types of structures and materials play an important role in the creation modern means of transport, including various grades of steel with different mechanical properties. For the rolling stock, proper operation and meeting the operational conditions is very important. Welded structures play an important role in the construction of various means of transport. Correct welding of carriages is important both in production and when carrying out various types of repairs. Each repair a carriage depends on its advancement and condition and the time of its operation. Each inspection for a refurbished carriage is defined either by the service life or the big distance traveled by the carriage. Important factor that may lead to damage is the effect of the load transported in the carriage. Therefore, the causes of the wear of the rolling stock are investigated and measures are taken to prevent any damage. The appropriate technical condition of the carriage also ensures safety on railroads for users and owners of the rolling stock. In the case of welded structures in carriages, it is influenced by poorly materials choice, incorrectly selected production processes and wrong selection of parameters. The goal of this paper is the mechanical properties analyse of weld low alloy steel structure of carriages after MAG welding using the parameters of the process. Thick-walled steel structures are used to build carriages, which is often a serious welding problem. The main role of welding conditions is connected with filer materials, welding technology, state of stress and temperature. In this paper, the properties of low alloy steel S3555J+N structures after MAG welding are presented. Furthermore, metallographic structure, tensile strength, bending test and impact toughness welded joints were analysed regarding welding parameters. The amount of acicular ferrite in WMD oxygen after welding was tested. Gas mixtures of argon and carbon dioxide with various percentage was used for shielding gas.
