What are the pipe welding positions?

Pipe welding positions can be divided into 4 groups: 1G, 2G, 5G and 6G.

• 1G Position. In the 1G welding position, the pipe is in the horizontal position and can be rotated along the horizontal (X) axis.
• 2G Position.
• 5G Position.
• 6G Position.
• Levels of Experience.

What positions can SMAW welding be performed in?

It is preferable to weld on work in the flat or horizontal position. However, when forced to weld in vertical or overhead positions it is helpful to reduce the amperage from that used when welding horizontally.

What weld positions are used only for pipe welding?

To begin with, pipe welding involves 4 different positions viz., 1G, 2G, 5G & 6G. In pipe welding generally the position of the specimen is fixed or it can be rotated or inclined along its axis according to the position of the welder.

What is G in 6G position means?

More by this Author. Our Editorial Process. Learn to identify 6G welding, the most commonly used kind of weld to test a welder for certification. The letter “G” stands for the type of weld, which is a grooveweld and the number “6” designates the position of the pipes welded.

What are the 4 basic pipe positions?

The above-mentioned welding positions, i.e, flat, horizontal, vertical, and overhead are the most basic types of welding positions used for plate welding.

What are the 5 SMAW operation set up?

SMAW Operation Set-up

1. Clean the workpiece.
2. Clamp the work close to the weld.
3. Insert the electrode into the insulated holder holder. Set amperage at levels recommended by the electrode manufacturer.
4. Determine the best arc length.
5. Have a chipping hammer available to remove any slag and before doing a 2nd pass with the weld.

What position is the SMAW 3F weld test performed in?

This type of welding is performed from the upper side of the joint. The face of the weld is approximately horizontal. Flat welding is the preferred term; however, the same position is sometimes called downhand….Flat Position Welding Procedures.

What is 5G in welding?

In the 5G position, the pipe is fixed at one or both ends and the welding operator must travel in one of two directions, either vertical-up or vertical-down. In this position, which is typically found in sub-assembly applications, the pipe is fixed at a 45-degree angle.

What is SMAW welding machine?

Manual metal arc welding (MMA or MMAW), also known as shielded metal arc welding (SMAW), flux shielded arc welding or stick welding, is a process where the arc is struck between an electrode flux coated metal rod and the work piece. Both the rod and the surface of the work piece melt to create a weld.
