TL;DR: In this article, three back-propagation artificial neural network models were used to predict the impact toughness of quenched and tempered pressure vessel steel exposed to multiple postweld heat treatment (PWHT) cycles, hardness of the simulated heat affected zone in pipeline and tap fitting steels after in-service welding, and hot ductility and hot strength of various micro-alloyed steels over the temperature range for strand or slab straightening in the continuous casting process.

TL;DR: In this paper, the feasibility of friction stir spot welding advanced high-strength steel sheet metals was investigated and the fixed pin approach was used to weld 600MPa dual phase steel and 1310MPa martensitic steel.
Abstract: An exploratory study was conducted to investigate the feasibility of friction stir spot welding advanced high-strength steel sheet metals. The fixed pin approach was used to weld 600MPa dual phase steel and 1310MPa martensitic steel. A single tool, made of polycrystalline cubic boron nitride, survived over one hundred welding trials without noticeable degradation and wear. Solid-state metallurgical bonding was produced with welding time in the range of 2 to 3 seconds, although the bonding ligament width was relatively small. The microstructures and hardness variations in the weld regions are discussed. The results from tensile-shear and cross-tensile tests are also presented.

TL;DR: In this paper, the quality of dissimilar weld joints between copper and stainless steel (SS) plates using electron beam welding with and without beam oscillation was evaluated through microstructural analysis, hardness, tensile, bend and impact tests.
