Abstract

A heat source model is proposed to simulate the effect of periodic and recurrent arcing and metal deposition phenomena in the cold metal transfer type of welding. This model will facilitate studying of weld pool behavior and resultant mechanical properties in detail for this type of welding. The proposed model utilizes a double-ellipsoidal heat source model as the basis and makes the geometrical and heat input parameters dependent on time.
