What is flat position welding?
1. Flat position. Also referred to as a “downhand” position, the flat position weld is the easiest and often the first weld that new students learn. The metals to be joined are placed flat, and the welder passes the electric arc over them, moving across the workpiece in a horizontal direction.
What are the four positions of welding?
Generally, welding positions are the angles at which metals are joined. They usually fall into four categories: horizontal, vertical, flat, and overhead.
What position is the metal piece in a flat welder?
For flat welding, the metal piece is in the horizontal position and remains parallel to the welder’s torso as he welds it while he stands in front of the machine.
Why is butt welding more complicated than flat welding?
The butt weld in the 2F/2f position may be somewhat more complicated than flat welding because the molten metal flows downward, and the torch is heated upward from the joint. Therefore, a uniform deposit is not possible at joints. Generally, welders should align the metals and secure the joint at both ends.
What clamps do you use for gripping pipes?

The 1G welding position is a position where the pipe is in horizontal positions & the pipe can be rotated against the horizontals axis or the X-axis. The welder does the welding from the top of the pipe. The position of the welder does not change.
What is vertical position welding?
For verticals position welds, both the weld & the plate will be located vertically. One of the major problems when performing these welds is the molten metal flowing down and accumulating. Welding in a vertical position downhill or uphill can prevent this problem.
What angle should the torch be held at when welding?
This position can be used to obtain either a fillet or a groove weld. For a fillet weld, the torch will be held at a 45-degree angle. The weld axis is horizontal. How the positions are executed depends on the type of weld.
What to use when welding in overhead position?
You may want extra protection on the top of your head, such as a bandana under your welding helmet. Use a fully leather welding jacket, especially with a process like stick welding, which produces more sparks and spatter.
How to get better results in vertical welds?
Adjust the weld parameters to achieve the best results in vertical welds. Use a reduced wire feed speed and voltage to make sure the puddle does not get too fluid and falls or sags out of the joint. If you’re using a welding power source with Auto-Set™ technology, be sure to use the parameters designed for a thinner material, even if you’re welding thicker base metal. This helps keep the heat input lower to fight gravity.
What is vertical weld?
Vertical welds can be done in either vertical up (moving bottom to top in the weld joint) or vertical down (moving top to bottom in the weld joint). Vertical up is typically more common, especially on thicker materials. This welding position may be required when you’re working on a large weldment that cannot be easily moved into the flat or horizontal position.
What is a weld number?
To help operators understand the type of weld joint (fillet or groove) and the weld position, each weld is given a number and a letter — 1G, 2G, 3G, 4G or 1F, 2F, 3F, 4F — to indicate the position and the type of weld required. Welds with a 1 are flat position, 2 is horizontal, 3 is vertical and 4 is overhead. F stands for fillet weld, while G is a groove weld. A fillet weld joins together two pieces of metal that are perpendicular or at an angle. A groove weld is made in a groove between workpieces or between workpiece edges. Using this system, a 2G weld is a groove weld in the horizontal position.
What is the best welding method?
Regarding processes and modes of transfer, here are some general guidelines: 1 TIG welding can be done in all positions. 2 Short-circuit MIG can be done in all positions. 3 Spray transfer MIG is recommended for flat and horizontal welding only. 4 Pulsed MIG can be used in all positions. 5 Stick and flux-cored welding can be used in all positions, but the choice of filler metal is the main driver in this.
Why is flat welding easier?
Generally, flat is an easier position to weld in since you’re not fighting gravity. The weld puddle stays fluid and wets into the joint evenly. As a result, operators can typically run hotter with higher deposition rates in the flat position because there is no worry about the puddle becoming too fluid and gravity pulling it out of the joint.
What is a WPS welding?
Welders are likely to see these designations in a welding procedure specification (WPS) or on filler metal data sheets, which use them to call out the positional capabilities of specific filler metals.
What are the different welding 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. However, these do not completely describe pipe welding positions. As far as pipe welding is concerned, there are four types of piping welding positions.

What is welding position 2F?
Welding position 2F is for a fillet weld where the welding is performed on the upper side of a horizontal surface and against an approximately vertical surface keeping to welding torch at a 45-degree angle.
Why care about Pipe Welding Positions?
Welding position is one of the most important variables that determine weld quality. For each pipe weld position, welders need to undergo certification processes. If a welder is qualified to weld in a 1G position, he is not allowed to weld hard positions like the 6G position. But on the other hand, if the welder is certified for the hardest 6G position then he can work in the 1G position. So, expertise over each weld position levels up a welder’s skills and qualifications.
What is vertical welding?
In vertical position welding, the weld axis is almost vertical. Both the weld and the plate will lie vertically. For welding vertical surfaces, the molten metal runs downward by gravity and pile up. Welding in an upward or downhill vertical position can resolve this problem.
Why is welding important?
The welding position is very important as it affects the flow of molten filler material. It’s desirable that the welding operator understands the types of welding positions to smoothly accomplish the task. Also, at a certain position of the welder different welding processes are performed. In this article, we will learn about ...
How to get rid of a high crown in welding?
In overhead welding positions, the metal deposited tends to drop or sag on the plate that results in a bead with a high crown. To get rid of this difficulty, the molten puddle should be kept small. When the puddle becomes too large, one can remove the flame momentarily for molten metal to cool.
What is flat welding?
The flat welding position is easier and faster and the molten metal is drawn downward. Flat welding position is also known as down hand welding position.
