Welding Positions

Sandeep Anand

This article is about different welding positions used in Plate Welding, Pipe Welding & Stud Welding.

Plate Welding Positions

In plate welding, we have four different positions namely;

  1. Flat position (1G or 1F)
  2. Horizontal Position (2G or 2F)
  3. Vertical Position (3G or 3F)
  4. Overhead Position (4G or 4F)

Note: 1. G Designates groove welding (V-groove, J-groove, U-groove etc.)
          2. F Designates fillet welds (“T” – Joint, Lap Joint etc.)

FLAT WELDING POSITION (1G OR 1F)

In flat welding the welders head remains above the test coupon.

 

HORIZONTAL WELDING POSITION (2G OR 2F)

In horizontal weld position, movement of electrode shall be in horizontal plane. We have two different welding techniques in horizontal welding, these are;

  1. Rightward technique
  2. Leftward Technique
VERTICAL WELDING POSITION (3G OR 3F)

In vertical weld position, movement of electrode shall be in vertical plane. We have two different welding methods in vertical welding, these are;

  1. Uphill
  2. Downhill
OVERHEAD WELDING POSITION (4G OR 4F)

Overhead position is one of the most difficult positions because welder has to work against the gravity. In overhead welding, the test coupon (or workpiece) remains above the head of the welder.

Pipe Welding Positions

In pipe grove welding, we have four positions;

  1. 1G (Rotated)
  2. 2G
  3. 5G
  4. 6G (Inclined at 450)

In pipe fillet welding, we have five positions;

  1. 1F (Rotated)
  2. 2F
  3. 2FR (Rotated)
  4. 4F
  5. 5F

Stud Welding Positions

In stud welds, we have three positions, namely;

  1. 1S
  2. 2S
  3. 4S

 

The 1S position is more or less like flat position, welders head will be above the weld joint.

2S position is similar to horizontal position, welder will move the electrode in horizontal plane.

4S position is similar to overhead position, welder’s head will be below the welding joint.
