|Title:||Dynamic Factors Contributing to Buckling and Birdnesting During GMAW Wire Feeding|
|Published:||June 01, 2005|
|Abstract:||This study provides experimental data for determining the factors affecting wire feeding performance. Full-scale experiments show that feeding performance, in terms of wire feed speed and wire feeding force, varies with the material system and with the spatial layout of the wire liner. Video analyses of the feeding process show that sway of the hose package can propagate through the wire liner to influence the exit wire feed speed and overall wire feeding force. When the hose package is looped, overall feeding forces can increase 400 to 500 %, thereby contributing to buckling and/or birdnesting of the welding wire.|
