1.2 The diameter of the electrodes to be used in SMAW depends on factors such as the workpiece thickness, the welding position, and the joint design. Large electrodes, with their corresponding high currents, tend to produce large weld pools. When welding in the overhead or vertical position, do you prefer using larger or smaller electrodes? 1.3 In arc welding, the magnetic field induced by the welding current passing through the electrode and the workpiece can interact with the arc and cause "arc blow." Severe arc blow can cause excessive weld spatter and incomplete fusion. When arc blow is a problem in SMAW, do you expect to minimize it by using DC or AC for welding?
