Abstract

High speed GMAW (gas metal arc welding) is an effective way to improve the welding productivity, however, its application is usually limited by the occurrence of several weld bead defects, such as humping bead. Based on the experimental results, a mathematical model is developed to analyze the forming mechanism of humping bead for high speed GMAW through considering both the momentum and heat content of the backward flowing molten jet in weld pools. One term related to the momentum of backward jet is added to the equation of weld pool surface deformation, and the heat content of overheated droplets is distributed within the layer covering the whole pool. The humping bead forming process and its dimension and 3D geometry are numerically simulated, and compared with the experimental measurement under some welding conditions. It is found that the model can describe and characterize the humping formation in high speed GMAW quantitatively.

Key words: welding high-speed GMAW humping weld bead numerical simulation
