How To Welding Vertical Position. When performing a groove weld the weld face will be along a vertical plane. In general vertical down is used on thinner sheets because it is considered less prone to burn through as it provides for reduced penetration and it is faster than vertical.
5G downhill position is a very good and productive way of welding pipes manually. When performing a groove weld the weld face will be along a vertical plane. Here the rod angle is tilted by 0 to 15 degrees away from the direction of travel.
The welder conducts welding from the side of the pipe with horizontal welding direction.
The MIG gun should be pointing upward between 35 to 45 degrees and tilting about 15 to 35 degrees toward the direction of the weld. There are two techniques to be followed in this position of welding. Always keep it to a tight stringer beads on any joint. To prevent burn through keep the wire directed away from the weld puddle and on the leading edge.
