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.
• Do not perform any welding while standing, kneeling or lying on the grounded
area. Failure to comply could result in electric shock.
• Never strike the arc or start welding without any adequate protection.
• Wear flameproof welding gloves, a heavy long-sleeved shirt, trousers without
cuffs, high-topped shoes, and an ANSI-approved welding helmet.
