Reduction Of Area

While the importance of through-thickness ductility in minimizing lamellar tearing during the welding of carbon steel plates is well known, the importance of through-thickness toughness has not yet been fully realized. Examination of several cracked fillet weldments has clearly identified two distinct modes of lamellar tearing, one dependent on ductility and the other on toughness. Correlations with multiple linear regression techniques were established for throughthickness elongation, reduction of area, fracture strength and toughness with chemistry, inclusion characteristics and microstructure. About 80 cracked weldments and plates were examined and it was found that both inclusion characteristics such as size, thickness and area and chemical characteristics such as Al, Mn, P and Si influence the through-thickness mechanical properties of the plates. To examine further, the effect of sulphur content, 333 plates from 185 different heats were analysed and tested. The beneficial effect of lower sulphur content (fewer sulphides) on through-thickness elongation, reduction of area, fracture strength and charpy V-notch impact strength was confirmed.

Cover Plates

The article is devoted to the actual problem of assigning optimal parameters for connecting steel plates on cover plates with angular welds that are widely used in construction practice. The article presents the results of a comprehensive study of operation of a welded assembly of the plates connection on cover plates. An algorithm is proposed for determining the optimal parameters of a welded joint with fillet welds on the cover plates, which makes it possible to obtain a strength balanced connection. The results of full-scale tensile tests of models were presented. These results confirmed the correctness of the assumed design assumptions, and made it possible to obtain a form of destruction, not characteristic and not described in the normative literature, expressed by cutting the main elements along the length of the overlap in the joint. The possibility of such a form of destruction was confirmed by the results of numerical research in a nonlinear formulation. The optimal parameters of the nodal welded joint determined by engineering calculation are confirmed by experimental studies, as well as by the results of numerical experiments on models of calculation schemes, taking into account the physical nonlinearity of the material operation. The obtained dependence for determining the bearing capacity of the joint by the cut-off mechanism and the expression for limiting the overlap length of the cover plates will make it possible to predict the nature of the fracture and design equally strong joints.
