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

1g welding position is a position where the pipe is in a horizontal position and the pipe can be rotated against the horizontal axis or the x axis.

There are more depending on certification but these are more or less the basics. G designates groove welding v groove j groove u groove etc 2.

Sheet fillet welds are divided into. That is why professional standard organizations such as asme aws iso jwes make rules and classifications for welding positions.

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. The position of the groove weld is divided into. Now to further explain. 5g pipe is horizontal groove is vertical pipe is fixed.

The welder conducts welding from the top of the pipe. 6g pipe is inclined 45 degrees from horizontal and fixed. Pipe welding positions can be divided into 4 groups. 1f 2f 3f 4f respectively ship type welding horizontal welding vertical welding overhead welding.

Different welding test positions based on aws and iso qualification based on test plates and pipes. 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. This is the easiest welding position.

Welder qualifies with 6g welding position is major concern of the most of the industries. Welders must be certified in each position in order to perform those types of welds. In this position a pipe in horizontal and the plate vertically are welded. Qualification for welder 1g 2g 3g 4g 5g 6g pipe welding positions 1g pipe welding position.
