Torch angle and manipulation
• The weld torch is pointed towards the weld
• Backhand welding gives better penetration and
normally produces a slightly more convex weld
bead. The risk for lack of penetration and slag
inclusions is reduced using backhand welding.
• Backhand welding is recommended for use
with rutile flux cored wires when maximum
penetration is required.
There are two main techniques of torch orientation when welding cored wires, i.e. backhand, and
• The weld torch is pointed away from the weld
• Forehand welding gives a smooth weld bead
appearance, but reduces penetration.
• Mostly used for standing fillets and is recommended for welding primed plates.(PB fillet
Recommended torch angle
For both forehand and backhand welding the gun
angle should be 10-20 degrees from the vertical.
Too large an angle can result in poor penetration,
unstable arc, porosity or poor impact toughness.
