Torch angle and manipulation
There are two main techniques of torch orientation when welding cored wires, i.e. backhand, and
• 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.
• 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.
