Refers to how the slag follows the puddle. If the slag is close, it ?crowds? the puddle, making it more difficult for the welder to observe the arc. If the slag follows fast, it allows for faster travel speeds. ?Good? slag follow is when the puddle is clear with the travel speed at a rate that keeps the puddle oblong.
Welding Tech
The brittle mass that forms over the weld bead on welds made with coated electrodes, flux cored electrodes, submerged arc welding and other slag producing welding processes. Welds made with the gas metal arc and the gas tungsten arc welding processes are slag free. Less oxidation generally makes slag more difficult to remove. Reducing speed usually helps.
Mode of metal transfer in gas metal arc welding at low voltage and amperage. Transfer takes place each time the electrode touches or short-circuits to the weld puddle, extinguishing the arc. The short-circuiting current causes the electrode to neck down, melt off, and then repeats the cycle.
A gas metal arc welding process variation in which the consumable electrode is deposited during repeated short circuits.
Protective gas used to prevent atmospheric contamination.
