Optimization of different welding processes using statistical and numerical approaches – A reference guide

Abstract

Welding input parameters play a very significant role in determining the quality of a weld joint.The joint quality can be defined in terms of properties such as weld-bead geometry, mechanical properties, and distortion. Generally, all welding processes are used with the aim of obtaining a welded joint with the desired weld-bead parameters, excellent mechanical properties with minimum distortion.Nowadays, application of Design of Experiment (DoE), Evolutionary algorithms and computational network are widely used to develop a mathematical relationship between the welding process input parameters and the output variables of the weld joint in order to determine the welding input parameters that lead to the desired weld quality. A comprehensive literature review of the application of these methods in the area of welding has been introduced herein.This review was classified according to the output features of the weld, i.e. bead geometry and mechanical properties of the welds.

Simultaneous Optimization of Joint Edge Geometry and Process Parameters in Gas Metal Arc Welding Using Integrated ANN - PSO Approach

“…Nozzle-to-plate distance (D), arc voltage (V ), wire feed rate (F ), and welding speed (S) are the most prominent parameters in GMAW process [1,3,5]. Similarly, process quality measures include Bead Penetration (BP), Bead Width (BW), Bead Height (BH), and Heat-A ected Zone (HAZ).…”

“…Previous predictive studies on GMAW process have had various purposes. Researchers have attempted to model GMAW process and then tried to optimize it through di erent methods [3,4].…”

Minimização de defeitos em revestimentos de superligas de níquel depositada pelo processo TIG com alimentação de arame frio

“…Para superar este problema e tornar menos oneroso o processo de avaliação das condições operacionais em soldagem, vários métodos estatísticos de projeto de experimentos têm sido desenvolvidos para otimização dos parâmetros de entrada em função de uma ou mais características do produto/processo que se deseja alcançar [11]. Dentre os vários métodos de projeto de experimentos, o método Taguchi tem se destacado nos últimos anos no cenário industrial, sendo aplicado no controle e otimização de processos de fabricação como fundição, furação, torneamento, eletrodeposição, dentre outros [12].…”

Economic evaluation for use of advanced welding equipment

“…Measurement and registration of supply functional characteristics parameters guarantees verification of its compliance with the required ones and ensures high quality of performing manual arc welding processes, both with a consumable electrode and in the shielding gas environment [9], [10].…”
