Types of Welding Positions – Information & Guide

Filed Under: How to's Last Modified: May 22, 2021

The welding position alludes to the situation of the welding administrator towards the work-piece to be welded. Due to gravity, the welding position influences the progression of liquid filler metal. It’s imperative to comprehend the sorts of welding positions as various welding measures need to be performed in a specific situation of the welder.

Methods have been created to permit welding in any position. Some welding measures have all-position abilities, while others might be utilized in just a couple of positions. Everything welding can be arranged by the situation of the workpiece or the situation of the welded joint on the plates or areas being welded.

Basic Welding Positions

According to American Welding Society (AWS) there are four welding positions that are explained below:

  • First refers to a flat position – either 1F or 1G
  • Second refers to a horizontal position – either 2F or 2G
  • Third is a vertical position – either 3F or 3G
  • Fourth is an overhead position – either 4F or 4G
Four Basic Welding Positions by AWS

Flat Position (1G and 1F)

The most effortless sort to perform is the level position, which is likewise in some cases called the down hand position. It includes welding on the top side of the joint. In this position, the liquid metal is drawn down into the joint. The outcome is a quicker and simpler weld.

A little puddle ought to be framed on a superficial level when making a dot weld with a welding pole. The welding bar is embedded into the puddle, and the base plate and bar are dissolved together. The light ought to be moved somewhat from one side to another to get a great combination. The size of the dot can be constrained by fluctuate the speed of welding and the measure of metal stored from the welding bar.

The movement of the fire ought to be controlled to meet the sidewalls of the plates and enough of the welding pole to deliver a puddle of the ideal size.

A liquid puddle of a given size can be conveyed along the joint by swaying the light tip. This will guarantee both complete infiltration and adequate filler metal to give some support at the weld. In 1G and 1F, the number 1 alludes to the level position, while the letter G represents a score weld and letter F represents a filet weld.

Horizontal Position (2G and 2F)

This is an out-of-position welding position. It’s a more troublesome position contrasted with the level position and it requires more ability from the welding administrator to do them well. Level welding – is somewhat harder to dominate than level position. This is because of the propensity of liquid metal to stream to the lower side of the joint.

The warmth from the light ascents to the upper side of the joint. The blend of these contradicting factors makes it hard to apply a uniform store to this joint. Adjust the plates and tack weld at the two finishes. The light should move with a slight wavering all over to appropriate the warmth similarly to the two sides of the joint, subsequently holding the liquid metal in a plastic state.

This forestalls the inordinate progression of the metal to the lower side of the joint and allows quicker hardening of the weld metal. A joint in a flat position will require significantly more practice than the past methods. It is, in any case, significant that the procedure is dominated prior to giving to different sorts of weld positions.

2G is a groove weld position that includes putting the welded hub in an even plane or around the level. Concerning the essence of the weld, it should lie in and around the vertical plane. 2F is a filet weld position, in which the welding is done on the upper side of the surfaces that are around the level that lies against a surface that is roughly vertical. In this position, the light is generally held at a 45-degree point.

Vertical Position (3F and 3G)

In this position both the plate and the weld lie upward or in an upward direction. The 3F and 3G elude to vertical filet and vertical section positions. When welding upward, the power of gravity pushes the liquid metal descending thus it tends to accumulate. To balance this, you can utilize either a vertical or downhill vertical position.

The progression of metal can be constrained by pointing the fire up at a 45-degree point to the plate and holding the bar between the fire and the liquid puddle (see above). The control of the light and the filler bar holds the metal back from hanging or falling and guarantees great entrance and combination at the joint.

Both the light and the welding pole ought to be wavered to store a uniform globule. The welding bar ought to be held somewhat over the centerline of the joint, and the welding fire should clear the liquid metal across the joint to circulate it uniformly.

To control this in the vertical position, point the fire up, holding it at a 45-degree point to the plate. Along these lines, the welder will utilize the metal from the lower portions of the work-piece to weld against the power of gravity. In the declining position, the metal from the upper parts and the electric circular segment’s active power are utilized.

Overhead Welding Position (4F and 4G)

In this position, welding is conveyed from the underside of the joint. It’s the most muddled and troublesome situation to work in. The 4G and 4F positions represent notch and filet welds individually. In the overhead position, the metal stored to the joint will in general list on the plate, bringing about a dab with a higher crown.

To forestall this, keep the liquid puddle little. In the event that the weld puddle turns out to be excessively huge, eliminate the fire briefly to permit the liquid metal to cool. The position level, even, vertical, and overhead are the essential kinds of welding positions. Be that as it may, they don’t sufficiently depict pipe welding positions. Line welding should be possible under various prerequisites.

Wrapping Up

Shortly, there are basic four types of welding positions. All the above-mentioned positions are also called AWS welding positions. All other positions are derived from these four. We can’t say which is better or not. The reason is that each weld position has its applications and usage. Just pick up your!
