Simulation-based numerical optimization of arc welding process for reduced distortion in welded structures

This paper presents an effective numerical approach for welding process parameter optimization to minimize weld-induced distortion in structures. A numerical optimization framework based on coupled Genetic Algorithm (GA) and Finite Element Analysis (FEA) is developed and implemented for a low and a high fidelity model. Classical weakly coupled thermo-mechanical analysis with thermo-elasto-plast...

Arc Welding Robot Automation Systems

Robot automation systems are rapidly taking the place of the human work force. One of the benefits is that this change provides the human work force with the time to spend on more creative tasks. The highest population of robots is in spot welding, spray painting, material handling, and arc welding. Spot welding and spray painting applications are mostly in the automotive industry. However, arc...

Multi-Objective Optimization of Submerged Arc Welding Process

Submerged arc welding (SAW) is an important metal fabrication technology specially applied to join metals of large thickness in a single pass. In order to obtain an efficient joint, several process parameters of SAW need to be studied and precisely selected to improve weld quality. Many methodologies were proposed in the past research to address this issue. However, a good number of past work s...

Optimization of Arc Welding Process Using a Genetic Algorithm Parameters

The purpose of this study is to propose a method to decide nearoptimal settings of the welding process parameters using a genetic algorithm. This method tries to find the near-optimal settings of the welding process parameters through experiments without a model between input and output variables. It has the advantage of being able to carry out searches without modifying the design space, which...
