Joining of stainless steel to carbon is widely used in various industries. Resistance spot welding (RSW) a suitable process for joining sheets. Due the complexity and importance optimizing parameters, numerical simulation this was considered. In research, electrical-thermal-mechanical RSW 304 St37 performed using finite element method (FEM). Then, simulated weld nugget size compared with experi...

Resistance spot welding (RSW) is widely used as a main joining technique in industry and the electrode caps are frequently replaced because of degradation during service. In this study, G type copper RSW were coated with Fe Ni based Fe3Al, FeAl, Ni3Al, NiAl alloys by Electro-Spark Deposition (ESD), providing resistance to hot deformation, oxidation Zn evaporation from sheet metal. The ESD teste...

This work aims to respond the need derived from highly changing and competitive nature of industrial environment in which resistance spot welding (RSW) process is implemented, providing an updated structured comprehensive overview advances that are being made field quality control improvement for this manufacturing process.

Nowadays, Multimedia Communication has been developed and improved rapidly in order to enable users to communicate between each other over the Internet. In general, the multimedia communication consists of audio, video and instant messages communication. This paper surveys the functions and the privileges of different VoIP protocols (i.e. InterAsterisk eXchange Protocol (IAX), Session Initiatio...

The star–triangle transformation is used to obtain an equivalence extending over the set of all (in)homogeneous bond percolation models on the square, triangular, and hexagonal lattices. Amongst the consequences are box-crossing (RSW) inequalities for such models with parameter-values at which the transformation is valid. This is a step towards proving the universality and conformality of these...

In the literature, computational puzzle schemes have been considered as a useful tool for a number of applications, such as constructing timed cryptography, fighting junk emails, and protecting critical infrastructure from denial-of-service attacks. However, there is a lack of a general security model for studying these schemes. In this paper, we propose such a security model and formally defin...

Clinching is a manufacturing method of mechanically joining two or more materials without the use heat additional components. This process relies on high plastic deformation to create secure bond. technology widely used for various grades and thicknesses. Especially in automotive industry, clinching an alternative resistance spot welding. However, load-bearing capacity clinched joints comparati...

In order to study the effect of spot welding parameters such as welding force, welding time and welding current intensity on nugget formation and its size in resistance spot welding process of CR3 low carbon steel sheets using ANSYS commercial software package. A 2D axisymmetric electro-thermo-mechanical finite element (FE) model is developed to simulate the nugget forming process and to predic...
