Welding Simulation of Complex Automotive Welded Assembly
2013Vor der Entwicklung der Computertechnik wurden Wärmeleitfähigkeitsprobleme hauptsächlich durch analytische Techniken gelöst. Analytische Berechnungen sind exakte Lösungen von Differentialgleichungen, bei denen physikalische Phänomene, wie z.B. die Temperatur, lokal für einen einzigen Punkt, unabhängig von der übrigen untersuchten Struktur, ermittelt ...

Simulating welding with shell elements
Journal de Physique IV, 2004Finite element simulations can be used to evaluate residual stresses and distortions induced by welding. Such simulations must account for complex interactions between thermal, metallurgical and mechanical phenomena. “Local” simulations are often sufficient for satisfactory predictions of residual stresses in the heat-affected zone (HAZ), but 3D ...

EFFECT OF VIRTUAL WELDING SIMULATOR ON TIG WELDING TRAINING [PDF]
, 2020 The objective of the study is to analyze the contribution of our simulator to assisting trainees in developing their TIG (tungsten inert gas) welding skills. With use of the developed virtual welding simulator, three-dimensional welding processes can be performed in virtual environments comparable to those that occur during real welding.

General Standard for Welding Simulation*
Materials Testing, 2011Abstract For differentiating the applicability of various numerical welding simulation methods as well as unifying the prerequisites and the steps to be taken in simulation, normative codes are required for the user. Since any standard-like documents are currently still lacking in this field, the DIN German Institute for Standardization ...

Research on Welding Deformation Simulation
Advanced Materials Research, 2011A method to obtain welding deformation values and simulating welding deformation effect is proposed in the paper. In this method, the structure is subdivided into Triangular element, the coordinates for nodes adopt the actual value, the coordinates of points are calculated with interpolation of all nodes in the element, and the normal vector of node is

Numerical simulation of weld nugget in resistance spot welding process
Materials Today: Proceedings, 2020Abstract The resistance spot welding (RSW) stands different over other welding techniques as the actual weld nugget is shaped internally relative to the surface of the base metal. The weld formed is fundamentally a mix of heat, pressure and time. The welding conditions are precisely controlled to produce sound nuggets.

Simulation of Friction Stir Welding
2010Abstract This article discusses the fundamentals of friction stir welding (FSW) and presents governing equations and an analytical solution for heat transfer. It provides the solutions for structural distortion in FSW. The article describes various techniques that have been adopted to solve the equations and simulate the FSW process. The

Simulation of Rotational Welding Operations
2010Abstract Friction welding is based on the rapid introduction of heat, causing the temperature at the interface to rise sharply and leading to local softening. This article illustrates the basic principles of direct-drive rotational friction welding and inertia friction welding. Modeling the effective friction response of the materials is

SUBMODELING SIMULATIONS IN FUSION WELDS
Journal of Multiscale Modelling, 2012The technological properties of fusion welds are formed due to the simultaneous effects of different physical phenomena which occur on different length scales. Correspondingly, the simulation of technological properties of fusion welds requires the multiscale approach.

Simulation of Arc Welding Process
Advanced Materials Research, 2013This paper presents a program for modeling and optimization of the arc welding process. Interface of the program is divided: time-synchronized monitoring multiple welding robots, a quick calculation options are various parameters, quickly replace the original design parameters (sequence of welding, etc.), the high degree of reliability modeling of ...
