- WELDING WORKBOOK. // Welding Journal;Feb2014, Vol. 93 Issue 2, p70
The article discusses the modes of metal transfer for gas metal arc welding (GMAW) and the factors in determining them. Metal transfer modes globular transfer, spray transfer and short-circuiting transfer are discussed. Factors influential to the identification of the modes such as electrode...
- Artificial Neural Network Prediction of Weld Geometry Performed Using GMAW with Alternating Shielding Gases. Campbell, S. W.; Galloway, A. M.; McPherson, N. A. // Welding Journal;Jun2012, Vol. 91 Issue 6, p174
An artificial neural network (ANN) model has been applied to the prediction of key weld geometries produced using gas metal arc welding (GMAW) with alternating shielding gases. This is a recently developed method of supplying two individual shielding gases to the weld area in which the gases are...
- Effects of current on droplet generation and arc plasma in gas metal arc welding. Hu, J.; Tsai, H. L. // Journal of Applied Physics;9/1/2006, Vol. 100 Issue 5, p053304
In gas metal arc welding (GMAW), a technology using pulsed currents has been employed to achieve the one-droplet-per-pulse (ODPP) metal transfer mode with the advantages of low average currents, a stable and controllable droplet generation, and reduced spatter. In this paper, a comprehensive...
