Semantic weldability prediction with RSW quality dataset and knowledge construction
Advanced Engineering Informatics, 2018Abstract This paper presents a semantic Resistance Spot Welding (RSW) weldability prediction framework. The framework constructs a shareable weldability knowledge database based on the regression rules from inconsistent RSW quality datasets. This research aims to effectively predict the weldability of RSW process for existing or new weldment design ...

Effect of Gap on AHSS RSW Weldability
SAE Technical Paper Series, 2009<div class="htmlview paragraph">When a gap exists in a resistance spot welded (RSW) joint, the lack of intimate contact between the members at the faying interface can have a significant influence on sheet steel spot weldability, especially for advanced high strength steels.

A via-loaded annular-ring RSW antenna
2008 IEEE Antennas and Propagation Society International Symposium, 2008Microstrip antennas excite surface waves and produce lateral radiation, and these fields deteriorate the radiation pattern due to diffraction and also couple with neighboring patches in an array environment. Recently, microstrip antennas denoted as ldquoreduced-surface-waverdquo (RSW) antennas were developed that minimize the surface-wave excitation ...

On Computer Simulation Models of RSW Process
2009 International Conference on Computer Engineering and Technology, 2009Due to its high complicacy and transitoriness and closeness, resistance spot welding (RSW), which is widely employed as a major sheet metal joining technology in automotive industry, has attracted specific attentions for computer simulations since last century. In this paper, four major RSW numerical models, namely thermal model, electro-thermal model,

Residual stress evaluation during RSW of DP600 sheet steel
Materials Testing, 2020Abstract In this study, resistance spot welding (RSW) process has been used on DP600 automotive steel at pressures of 2, 3, 4, 5 and 6 bar at a welding current of 7 kA. Microstructure, hardness and residual stress were examined to evaluate the effect of the welding pressure.

A Case Study of Reinforced Self-Supported Retaining Wall (RSW)
Applied Mechanics and Materials, 2013With increasing land prices and a lack of space in urban areas, urban construction sites are requiring deeper and larger excavations. For this reason, excavation is becoming more important. With deeper excavation, the retaining wall system needs to be adjusted, and a support system for retaining walls needs to be established so that the construction ...

RSW Modons and their Surprising Properties: RSW Turbulence
2018AbstractBy using quasi-geostrophic modons constructed in Chapter 6 as initial conditions, rotating-shallow-water modons are obtained through the process of ageostrophic adjustment, both in one- and in two-layer configurations. Scatter plots show that they are solutions of the rotating shallow-water equations.

Weldability Improvement Using Coated Electrodes for RSW of HDG Steel
SAE Technical Paper Series, 2006<div class="htmlview paragraph">The increased use of zinc coatings on steels has led to a decrease in their weldability. Weld current and time need to be increased in order to achieve sound welds on these materials compared to uncoated steels, and electrode tip life suffers greatly due to rapid alloying and degradation.
