BACKGROUND Over the last 2 decades arthroscopic stabilization and Bankart repair has gained popularity due to the advances in materials and surgical techniques. Results of arthroscopic stabilization have been similar to open without the risks of it. The number of anchors used has been suggested to be very important in "spot-weld" arthroscopic stabilization however the "purse-string" technique (...

High-strength aluminum alloys are of increasing interest to the aerospace and automotive industry for critical high-strength components. B-pillars and door beams being of particular interest to the automotive industry Refill friction stir spot welding (RFSSW) offers an attractive means of joining these difficult-to-weld alloys since bulk melting is avoided and no exit hole is left. In this stud...

Fast Breeder Reactor (FBR) steam generator assembly, is a shell and tube heat exchanger. In this equipment, steam is generated by the transfer of heat from sodium on shell side to water on tube side. Due to inherent dangers of sodiumwater reaction, the integrity and leak tightness of weld joints separating sodium and water/steam is very important. The tube to tube sheet (TTS) weldsin steam gene...

The performance of laser welding of Ti and two dental precious alloys (Ag-Pd-Au, Au-Pt-Ag) was investigated by mechanical testing and microscopic observation, using butt joint as design. The laser irradiation was done using a commercial Nd:YAG dental laser-welding device in a single pulse mode with output currents 150, 200, 250, 300A, spot diameters 0.6, 0.9, 1.2mm, and pulse duration 10ms. The...

The welding process parameters of resistance spot are determined by quality indicators, such as nugget diameter, and tensile shear test behavior, failure load location. In this study, deep-learning models were investigated to predict the indicators from base materials parameter information. For each model, hyperparameters, number hidden layers, nodes in layer, learning rate optimizer, epochs, o...
