# Bevelling

## Bevelling joint edges 

To provide the best penetration for a weld, it is essential to allow space for filler materials to be introduced. One way we can do this is by chamfering the joining ends. In this process, a 45 degree bevel is added to the edge of the stock. 

### Why bevel?

When two opposing chamfered edges are brought together, they create a groove. This allows the filler material deeper penetration in the stock, thus, creates a stronger weld. It is also critical when planning to grind back exposed welds, as it effectively allows the weld to sit 'within' the material, \
rather than 'on top' of it.

### How to bevel

Use the linisher or an angle grinder with a flap disk to bevel the edges of all joining edges.
