19 Dec Welding Positions

Welding is often done on structures in the position in which they are found. Techniques have been developed to allow welding in any position. Some welding processes have all-position capabilities, while others may be used in only one or two positions.

All welding can be classified according to the position of the workpiece or the position of the welded joint on the plates or sections being welded. There are four welding positions, which are illustrated below.Picture 1

Fillet Welding Positions – Fillet, groove and Surface welds may be made in all of the positions shown below.Picture 2

Flat Position Welding – In this position, the welding is performed from the upper side of the joint, and the face of the weld is approximately horizontal. Flat welding is the preferred term, but it is also referred to as a Down hand.

Horizontal Position Welding – The axis of a weld is a line through the length of the weld, perpendicular to the cross-section at its centre of gravity. Fillet Weld, Groove Weld, Horizontal Fixed Weld, and Horizontal Rolled Weld can all be done in this welding position.

Vertical Position Welding – In this position, the axis of the weld is approximately vertical. Vertical welding positions are shown in view C in the image above.

Overhead Position Welding – In this welding position, the welding is performed from the underside of a joint. Overhead position welds are illustrated in view D in the image above.

Pipe Welding Positions – Pipe welds are made under many different requirements and in different welding situations. The welding position is dictated by the job. In general, the position is fixed, but in some cases, it can be rolled for flat-position work.
