Torch angle and manipulation

Backhand welding

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

forehand welding.

•฀ The weld torch is pointed towards the weld

bead.

•฀ 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.

Forehand welding

•฀ The weld torch is pointed away from the weld

bead.

•฀ 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

welds)

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.
