What term describes the rate at which an electrode melts into the weld pool?

The term that describes the rate at which an electrode melts into the weld pool is known as the deposition rate. This measurement indicates how much welding filler material is added to the weld joint per unit of time. A higher deposition rate means that more material is being melted and added to the joint, which can affect the overall productivity of the welding process as well as the properties of the finished weld.

In the context of Gas Metal Arc Welding (GMAW), the deposition rate is influenced by several factors, including the amperage, voltage, and travel speed. When the settings are optimized, a welder can achieve an efficient deposition rate, leading to strong and durable welds. Understanding the deposition rate is crucial for welders as it helps them evaluate and adjust their welding parameters to achieve the desired weld quality while maximizing efficiency.
