Abstract

Behavior of leading and trailing arcs in twin-wire submerged arc welding has been investigated with help of transient heat transfer analysis. An appropriate heat transfer model with dissimilar heat sources at leading and trailing arcs has been considered. The model has been simulated with different combinations of model parameters. Computed and experimentally measured temperatures have been compared and geometrical and heat distribution differences between leading and trailing heat sources have been suggested. The behavior of leading and trailing arcs along with comparison between the current and the conventional approach has been presented and discussed. The simulation indicates that the leading arc has a major share in producing penetration where as the trailing arc is more responsible for melting. Copyright © Taylor & Francis Group, LLC.
