The two main types of GMAW transfer are: Spray or globular transfer. Short-circuiting or dip transfer. Spray Transfer/Globular Transfer. This type of metal transfer generally occurs at high current and high arc voltage ranges, e.g., 250 - 600 Amps at 28 - 40 volts. As the current is increased the rate at which the droplets are transferred across the arc increases and they become smaller in volume. The droplets can be seen in a high-speed cine film but cannot be seen with the naked eye. It appears as if there is a spray of metal.

The main purpose of Industrial Welding Training is helps plant maintenance workers develop a working knowledge of and learn the theory behind gas and arc welding techniques and equipment, and the cutting of steel, pipe, iron and nonferrous metals.
