In which position is a "flat welding position" performed?

The flat welding position is performed when the workpiece is positioned horizontally. In this position, welders can work on the top side of the joint, which allows for easier access and control. This leads to improved penetration and fusion of the weld, resulting in stronger joints. The flat position is often preferred because it reduces the risk of weld defects and provides better visibility and stability for the welder.

The other positions, such as vertical, angled, or suspended workpieces, present different challenges in terms of gravity and welding technique, which can affect the quality of the weld. Working in a horizontal position, in contrast, leverages gravity's benefit, making it advantageous for attaining high-quality welds with less effort.
