A simulation model was developed for the monitoring, controlling and optimization of the Friction Stir Welding (FSW) process. This approach, using the FSW technique, allows identifying the correlation between the process parameters (input variable) and the mechanical properties (output responses) of the welded AA5754 H111 aluminum plates. The optimization of technological parameters is a basic ...

The present contribution is the first research reporting full penetration HLAW joints in 15 mm thick EH36 steel butt T-welds with square grooves on 2F welding position by single-sided welding. effects of parameters were investigated to increase quality joints. Conditions leading defect-free welds fulfilling naval regulations includes a laser power 12.5 kW, speed 1.6 m/min and vertical offset di...

Friction stir welding (FSW) is an innovative process that has been successfully used in joining aluminum alloys, normally difficult to weld. Important advantages over fusion welding are better retention of baseline material properties, lower residual stresses and excellent mechanical properties. Defects that occur in FSW joints are due to improper tooling or setup. Non-destructive techniques us...

In the present study, the evolution of microstructure in laser-welded joints of ferrite-based dual-phase Fe-Al-Mn-C steel sheets was analyzed and its effect on the mechanical properties of the joints was investigated. Laser welding was performed using different powers and welding speeds to attain different heat inputs. Electron backscatter diffraction (EBSD) examinations and hardness measuremen...

Fatigue characteristics of welded joints alloy 01420C made by resistance spot welding and automatic argon arc are obtained. The highest durability was shown with a longitudinal weld. Joints Produced simulating the edge line reinforced element have comparable to an unloaded weld spot, which in turn is inferior joint elements limited cross-section repair mechanical cut similar standard sample for...

Friction stir welding is a solid-state joining process widely used in several industrial applications. One of its variants, orbital friction welding, key importance fundamental industries such as oil and gas aerospace. For there need to develop not only new parameters but also tools ancillary mechanisms that can ensure sound, high-performing joints are obtained. This review assesses the current...

The paper deals with the analysis of influence parameters resistance spot welding. Resistance welding is high-efficiency process for joining metallic materials. application still most used method car body parts. was determined by an experiment. optimal achieving highest load-bearing capacity joints material TRIP40 / 70 a defined thickness 0.77 mm were determined. results reached values from 630...

The fatigue cracks of rib-to-deck welded joints in an orthotropic steel deck are one the critical conundrums that restrict sustainable development bridges. Double-sided were achieved by introducing internal welding technology to overcome initial “crack-like” manufacturing defects at roots single-sided joints. Through observation macro-section joint, differences between welding, partial-penetrat...
