relation to the weld puddle. The gun is either PUSHED (see Figure 11) into the weld pud- dle or PULLED away from the weld puddle.

centered over the weld joint. This is the easi- est type of bead to make.

PUSHPuddle PULL

Figure 11. Travel Direction

For most welding jobs you will pull the gun along the weld joint to take advan- - tage of the greater weld puddle visibility.

2.TRAVEL SPEED is the rate at which the gun is being pushed or pulled along the weld joint. For a fixed heat setting, the faster the travel speed, the lower the penetration and the lower and narrower the finished weld bead. Likewise, the slower the travel speed, the deeper the penetration and the higher and wider the finished weld bead.

TYPES OF WELD BEADS

The following paragrap_hs discuss the most commonly used weldin_]'beads.

Once you have the gun in position with the wire lined up on the weld joint, lower your helmet, pull the trigger and the arc will start. In a second or two you will notice a weld puddle form and the base of the bead be ginning to build. It is now time to begin to move with the gun. If you are just learning to weld, simply move the gun in a straight line and at a steady speed along the weld joint. Try to achieve a weld with the desired

penetration and a bead that is fairly flat and consistent in width.

As you become more familiar with your new welder and better at laying some simple weld beads, you can begin to try some different weld bead types.

There are two basic types of weld beads, the stringer bead and the weave bead.

1.The STRINGER BEAD (Figure 12) is formed by traveling with the gun in a straight line while keeping the wire and nozzle

2.The WEAVE BEAD (Figure 13) is used when you want to deposit metal over a wider space than would be possible with a stringer bead. It is made by weaving from side to side while moving with the gun. It is best to hesitate momentarily at each side before weaving back the other way.

WELDING POSITIONS

There are four basic welding positions: flat, horizontal, vertical, and overhead.

1.The FLAT POSITION (Figure 14) is the easiest of the welding positions and is most commonly used. It is best if you can weld in the flat position if at all possible as good results are easier to achieve.

2.The HORIZONTAL POSITION (Figure 15) is next in difficulty level. It is performed very much the same as the flat weld except that
