Welding Horizontal Vertical Position. PB - Welding in horizontal vertical position - PROMOTECH. In this position the weld axis remains horizontal and the weld is facing the vertical plane.
Fillet joints in the flat horizontal vertical and overhead position are designated as 1F 2F 3F and 4F respectively. 2F is a fillet weld position in which the welding is done on the upper side of the surfaces that is approximately horizontal that lies against a surface that is approximately vertical. Horizontal-position welding can be used on tee lap joints butt joints and tee joints.
When performing a groove weld the weld face will be along a vertical plane.
Welding position in which the welding is horizontal with the centreline of the weld vertical. In the horizontal welding position the weld bead is on the upper side of the horizontal surface and against a vertical surface by keeping an axis of weld in horizontal position. Figure 3-16 shows the weld axis and weld face. Welding Position according to ISO 6947 Flat Position PA.
