1g 2g 3g 4g 5g 6g Welding Position

Welders must be certified in each position in order to perform those types of welds.

1g 2g 3g 4g 5g 6g welding position. 1g 2g 5g and 6g. Welder had to make a fillet weld overhead. 6g pipe is inclined 45 degrees from horizontal and fixed. It is very uncommon and not a easy task to perform.

Now to further explain. 5g pipe is horizontal groove is vertical pipe is fixed. Welder qualifies with 6g welding position is major concern of the most of the industries. Pipe welding positions can be divided into 4 groups.

The welder conducts welding from the top of the pipe. Weld performed on plate butt in 1g position will qualify weld in same position on 150 nb pipe or greaterhowever the same rule does not apply for plate welded on 3g and 4g which qualifies welding in 1gany one have gone through with discussion on this subject matter. There are more depending on certification but these are more or less the basics. Sheet fillet welds are divided into.

1g 2g 3g 4g 5g 6g to distinguish between flat welding horizontal welding vertical welding overhead welding horizontal horizontal welding and pipe inclination 45 degree fixed welding. 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 flat vertical overhead 1g2g3g4g1f2f3. In untrained hands welding can be a safety hazard.

The position of the groove weld is divided into. That is why professional standard organizations such as asme aws iso jwes make rules and classifications for welding positions. There is also a 6gr position which is the 6g position with a restriction simulating ring around the pipe. Horizontal position 2g or 2f vertical position 3g or 3f overhead position 4g or 4f note.

In this position a pipe in horizontal and the plate vertically are welded. G designates groove welding v groove j groove u groove etc 2.
