Fillet welds are one of the most commonly used weld joints but one of the most difficult to weld consistently. This paper presents a technique using Artificial Neural Networks (ANN) to identify the key Gas Metal Arc Welding (GMAW) fillet weld parameters and interactions that impact on the resultant geometry, when using a metal cored wire. The input parameters to the model were current, voltage,...

To solve the knowledge modelling problem of strong nonlinear characteristics such as multivariable, high coupling and stochastic interference in GMAW process hull structures, a clustering similarity particle filter (CSPF) method based on consistency principle state trajectory is proposed to establish model for welding dynamics. The mechanism selected construct Hammerstein with uncertain noise r...

The manufacturing of structures ranging from bridges and machinery to all types seaborne vehicles nuclear reactors space rockets has made considerable use arc welding technologies. This is as a result benefits including increased joint efficiency, air water tightness, no thickness restriction (0.6 25 mm), decreased fabrication time cost, etc. when compared alternative methods. Gas metal (GMAW) ...
