2. Perform Weld Carbon Steel Plates In Horizontal Position

After performing Weld Carbon Steel Plates In Horizontal Position, Let the trainer evaluate your work.


INFORMATION SHEET NO. 1.2-1Horizontal Welding

When welding in the 2G or 2F position it is necessary to control the weld puddle and travel speed to produce a strong weld. The horizontal position is used widely in agricultural sectors to make repairs.

The steps necessary to perform welds in the 2G or 2F position are:

-Secure the plate in a position for running beads in a straight line from left to right. Use adjustable locking piers or C-clamps to secure the metal firmly.

-When performing this type of weld, the electrode and the plate sides should form a 90 angle. Lean the electrode slightly in the direction of the weld area.

-Adjust the amperage, travel speed, and arc length to prevent the weld puddle from running or sagging.

-Metal that is over 1/8 inch thick should be beveled prior to welding in the horizontal position. If welding thicker metal, or metal that has been beveled, it is necessary to make more than one weld pass to enhance the strength of the weld.

-A root, filler, and cap pass will be necessary.

2. Perform Weld Carbon Steel Plates In Vertical Position

After performing Weld Carbon Steel Plates In Vertical Position, Let the trainer evaluate your work.


INFORMATION SHEET NO. 1.3-1Vertical Welding

There are two basic techniques for performing welds in the vertical position. These two techniques are commonly referred to as vertical up and vertical down. These two techniques can be used to perform welds in the 3G and 3F positions.

The following is a set of instructions for performing vertical up and vertical down welds. For most welders, light metal is easier to weld than heavy metal because it requires less penetration.

Be certain that the metal plate is secured in a vertical position. The use of adjustable locking pliers or C-clamps is recommended to aid in securing the metal in position.

Position the electrode at an angle of 60 to the plate and in the path of the weld. The electrode should be perpendicular to the sides of the plate.

For vertical down welding, begin at the top of the plate with a short arc. If the electrode sticks, stop and increase the amperage. If the electrode burns through the metal, lower the amperage. If the electrode continues to burn through the metal, increase the speed of the electrode movement downward.

When welding vertical up, position the electrode 85 to the plate in the path of the weld. Begin at the bottom of the plate and work up. Use the same procedures if the electrode sticks or burns through the metal.

As you become better at welding in the 3G and 3F positions, begin work on thicker metals. Experiment and increase the amperage accordingly. When welding thick plate, use one or more side-to-side electrode movements.

As with fillet welds, vertical up and vertical down welds will need more than one pass. A root pass should be made, along with a filler and cap pass.

1. READ INFORMATION SHEET NO. 1.4-1 on WELD CARBON STEEL PLATES IN OVERHEAD POSITION (4G)After reading INFORMATION SHEET NO. 1.4-1 proceed to Task Sheet 1.4-1

2. Perform Weld Carbon Steel Plates In Overhead Position

After performing Weld Carbon Steel Plates In Overhead Position, Let the trainer evaluate your work.


INFORMATION SHEET NO. 1.4Overhead Welding

Welding in the 4G or 4F position is the most difficult of the out-of-position welds. The major challenge in this type of welding is controlling the weld puddle. The procedures for performing overhead welds are very similar to the flat position, except that they are far more difficult. It is necessary to pay special attention to the weld puddle and travel speed. You must maintain a short arc as well.

The steps in overhead welding are:

Secure the metal overhead with the use of an adjustable locking pliers or C-clamps.

Find a position that is comfortable for you before starting to weld. Welding in the 4G or 4F position is much more difficult if the welder is uncomfortable from the start.

Adjust the amperage setting and travel speed. The amperage should be set at approximately the same setting as needed during vertical welding (3). Be certain to maintain a very short arc length throughout the entire process.

Weld with a short arc and use a moderately fast rate of travel to prevent sagging and undercutting.

A weaving pattern is recommended for use on heavier metals. This motion must be faster than weaves used for other position welds. Three passes will be needed to complete this weld properly.
