Welding techniques

WARNING!
Potential hazard that could result in serious injury or loss of life.
• Prolonged exposure to the welding arc can cause blindness and burns.
• Do not perform any welding while standing, kneeling, or lying on the grounded
area. Failure to comply could result in serious injury or loss of life.
Torch travel: The movement of the torch along the weld joint. For a solid weld bead, the
•
welding torch should be moved steadily and at the right speed along the weld joint. Moving
the torch too fast, too slow, or erratically prevents proper fusion or creates a lumpy, uneven
bead.
Travel direction: The direction of the torch moving along the weld joint in relation to the weld
•
puddle. The torch is either pushed into the weld puddle or pulled away from the weld puddle.
For most welding jobs, pull the torch along the weld joint for greater weld puddle visibility

.
• Travel speed: The rate at which the torch is being pushed or pulled along the weld joint. For a
fixed heat setting, if the travel speed is faster, the penetration will be low and the finished
weld bead will be low and narrow. Likewise, if the travel speed is slow, the penetration will be
deep and the finished weld bead will be high and wide.
