The gas metal arc welding (GMAW) process uses four basic modes to transfer metal from the electrode to the workpiece. Each mode of transfer depends on the welding process, the welding power supply, and the consumable, and each has its own distinct characteristics and applications. Meer weergeven In short-circuit transfer, the electrode touches the work and short circuits, causing the metal to transfer as a result of the short. This happens at a rate of 20 to more than … Meer weergeven Spray transfer is named for the spray of tiny molten droplets across the arc, similar to spray coming out of a garden hose when the opening is restricted. Spray transfer … Meer weergeven Globular transfer means the weld metal transfers across the arc in large droplets, usually larger than the diameter of the electrode being used. This mode of transfer … Meer weergeven In the pulse-spray transfer mode, the power supply cycles between a high spray transfer current and a low background current.
