Welding techniques
1. For a solid weld bead, move the welding
torch steadily and at the right speed
along the weld joint.
Note: Moving the torch too fast, too slow or
erratically prevents proper fusion and/ or
creates a lumpy, uneven bead.
2. Move the torch (1) towards the weld
puddle or away from the weld puddle
(fig Y)
.
Note: For most welding jobs, move the torch
along the weld joint for greater weld puddle
visibility.
Note: For a fixed heat setting, when the speed
is increased, a decrease in penetration and a
narrowing of the finished weld bead will result.
WARNING!
Potential hazard that could result in serious injury or loss of life.
•
Prolonged exposure to the welding arc can cause blindness and burns.
