This article provides information on heat and mass transfer from the arc to the base metal in the gas-metal arc welding (GMAW) process. It discusses the development of welding procedures and the general operation of the process. The issues described in this article include the: total heat transferred to the base metal; partitioning of heat transfer between the arc and the molten electrode droplets; transfer modes of the droplets; role of the arc in droplet transfer; and simple model for welding procedure development based on an understanding of heat and mass transfer to the base metal.
