The is officially defined as an Overhead Fillet Weld . This means the welder performs the weld from the underside of the joint, with the weld axis roughly horizontal, and the face of the weld lying in a horizontal plane. Gravity is the welder's primary enemy here, as molten metal wants to drip, sag, or fall onto the workpiece or the welder. | Feature | Description | |---------|-------------| | |
