WebAug 1, 2013 · Gas metal arc welding (GMAW) is an effective method for joining light-gauge metals such as carbon steel and austenitic stainless steel. Thin-gauge materials—24-ga. to 0.1875-in. carbon steel and 18-ga. to 0.1875-in. stainless steel—are used in applications such as HVAC, automotive, mobile machinery guards and cabs, and small … WebNov 12, 2013 · Welding electrical signal measurement and high speed camera are employed to study the differences of short circuiting metal transfer between …
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 200 times per second. The advantage of the short-circuit transfer is its low energy. This method is normally used on thin material ¼ inch … See more 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 generally is used on carbon steel only and uses 100 … See more 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 usually is … See more In the pulse-spray transfer mode, the power supply cycles between a high spray transfer current and a low background current. This allows for supercooling of the weld pool during the … See more WebThe sequence of metal transfer during the short-circuiting transfer method. A—The welding wire short-circuits to the weld pool.
