Tungsten electrode sharpening (beveling and grinding)

The tungsten electrode shape and geometry is an essential parameter in TIG welding that is considered during developing Welding Procedure Specification (WPS).

Tungsten geometry affects the arc starting and shape, and hence, it affects the shape of the weld bead and its penetration.

The angle degree is essential, and it is always recommended to follow the welding machine manufacturer’s suggested angle for optimal use of the welder. If the angle is not specified, you should optimize the tip angle to your particular welding operations.

The most crucial point to remember during grinding for optimum arc stability is to grind the tungsten lengthwise (the axis of the electrode perpendicular to the axis of the grinding wheel).

Lengthwise grinding reduces the tungsten contaminating the weld and creates a pattern on the rod that does not strict the current and maintain arc stability.

The crosswise grinding restricts the welding current; restricting the current may cause the arc to wander and subsequently multiple welding defects.
