Opis:
In the mobile platform structure, there is an increasing necessity to weld steels from the various groups. For instance, it has become necessary to connect AHSS (Advanced High-Strength Steel) with fine-grained steels. This article verifies the possibility of obtaining accurate mixed welded joints from different grades of DOCOL 1400 steel (from the AHSS group) with S700 MC steel (from the fine-grained steel group). The structure, quality and mechanical properties of the obtained welded joints were thoroughly analysed. The joints were made at various welding speed with preheating to 80°C and without preheating.

Opis:
There is an increasing demand for mixed joints made of hard-weldable steels used in the construction of transport means. An illustration of this is the welding of movable platform elements such as a pin to arm joints. The pin is made of high-strength structural steel S690 QL (1.8928) while the arm of the movable platform is made of DOCOL 1200M steel from the AHSS group (Advanced High-Strength Steel). Such a joint is not easy to make due to the different chemical composition of both steels. The difference in thickness of welded elements creates an additional difficulty. The thickness of the cylindrical pin is 40 mm, whereas the thickness of the sheet metal used for the platform arm is much smaller and amounts to 2 mm. Joints of varying thickness and chemical composition tend to produce cracks in the heat-affected zone as well as in the weld. The purpose of this article is to determine the most appropriate welding parameters and the selection of additional materials to obtain correct joint with good mechanical properties, free of welding defects and incompatibilities.

Opis:
In the construction of mobile platforms, there is an increasing necessity to weld steels from the AHSS group (AHSS - Advanced High-Strength Steel) with low-alloy steels. This article verifies the possibility of obtaining accurate mixed welded joints from different grades of AHSS steel with S355J2 steel. The structure, as well as mechanical properties of the obtained welded joints, were thoroughly analysed.

Opis:
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:
The developing automotive industry has prompted an increase in the demand for new welding technologies in civil engineering and transport that reduce the mass of mobile platforms mounted on vehicles and increase their operational range at the same time. The AHSS steels are the materials most commonly adapted for the production of motor vehicles due to their high tensile strength. Nonetheless, the joints created with their use are less strong from the native material. This article examined whether the application of micro-jet cooling would alter the mechanical properties of the welds. Based on the performed tests, joints with better quality that passed positively in the hardness and tensile strength evaluations were obtained. The presented research proves that the use of additional elements in the welding process significantly affects the quality of the obtained welds and brings satisfactory results with a greater repeatability than before.
