Which electrode inclination is typical in most FCAW techniques?

In FCAW, the angle of the electrode affects how the heat and molten metal are directed into the joint, as well as arc stability and slag behavior. A backhand (drag) technique with the electrode tilted about 10 to 30 degrees from the work surface is typical because it promotes a stable arc through the flux, good fusion into the joint, and smooth slag flow and removal. If the angle is too shallow (near 0–10 degrees), you can get weaker penetration and poorer slag control. If it’s too steep (45–60 degrees), the arc becomes hard to control, the bead can become too wide or distorted, and slag issues can increase. So, 10° to 30° backhand hits the right balance for most FCAW welds.
