The edges of plates usually need to be prepared before welding, and this preparation is essential for the subsequent welding operation. In some cases, when the plate thickness is less than 5 mm, edge preparation may not be required.
A chamfer is the angle formed between two inclined planes created by the bevels of both plates at the joint, typically ranging from 60° to 70°. It can also be defined as the material removal at the edge of plates or pipes used in the preparation of welded joints to improve weld penetration.
Chamfering or bevelling is used to increase the load-bearing capacity of plate and pipe joints.
CEVISA bevelling machines provide an efficient and precise solution for weld preparation in accordance with DIN EN 29692.
