Effective Use

The magnitude of different aluminium alloys, especially the ones with higher strength, are increasing in the structural engineering, not just the usual applications (like the aerospace industry) but more likely in the automotive industry. There are more assumptions of the effective use of aluminium; we should highlight two important factors, the technological and the applicability criterions. The technological criterion is the joining of structural elements, frequently with welding thus the technological criterion ultimately is the weldability. The assumption of applicability comes from the loading capability of these structures, which is typically cyclic loading so the key issue from the point of view of applicability is the resistance to fatigue. This article represents physical simulation and fatigue test results both on the base material and on the welded joints.

Ring Analysis

The welding residual stress has different effects on the mechanical properties of aluminum alloy welded joints, such as size stability, fatigue strength and stress corrosion cracking. Therefore, it is very important to evaluate the welding residual stress accurately. In this paper, the residual stress of A7N01 aluminum alloy welded joints was measured by X-ray diffraction. In contrast to the traditional method, the cos[Formula: see text] method was used in this paper, the results were compared with those obtained by the conventional [Formula: see text] method. In addition, the influence of oscillation unit on the test results of the cos[Formula: see text] method was studied.

Penetrant Testing

Abstract It has been compared the dimensions of indications obtained in colour liquid-penetrant inspection. The indications arose from simulated pores drilled in test elements. The series of penetrant tests included different structural materials. On the basis of test results it has been ascertained the possibility of evaluation of the pores depth as well as it has been determined recommended development times for different constructional materials

The paper presents the test results on the fatigue crack growth under cyclic bending specimens at constant moment amplitude made of S355 steel with fillet welds. Plane specimens with stress concentrators in form of the external two-sided blunt notches were tested. The tests were performed under constant value of the stress ratio R = –1 without and after heat treatment. The article also presents the test results of the microstructure of welded joints taking into account changes in the material after heat treatment and the impact of these changes on the fatigue life of specimens. Keywords: welded joints, fatigue cracks length, number of cycle, bending, microstructure

Negative Temperatures

The experimental test results of strength of glued and glued-welded joints at room and negative temperatures after long exposure of them at –30 °С and –50 °С are presented. As glue materials, epoxy adhesive, anaerobic adhesive-sealant, silicone sealant and adhesive-melt based on copol-ymer of ethylene with vinyl acetate were used, as substrates, steel and aluminum alloy samples were used. It has been found out that silicone sealant ensures the best strength of glued-welded joints at low temperatures. It was determined that for all the studied types of the glued-welded joints, strength at –30 °С was worse than at –50 °С.
