Bevel Types for Butt Welding

Bevel Type 10

Bevel type 10 means square butt welding.

Relevant parameter:

• Gap

Bevel Type 11

Bevel type 11 means square butt welding with overlap.

Relevant parameter:

• Gap

Bevel Type 20

This bevel type is a V-joint (without any nose).

Relevant parameter:

• Alpha (α)

• Gap

Bevel Type 30

This bevel type is a Y-joint, i.e. a V-joint with a nose (of fixed height).

Relevant parameter:

• Alpha (α)

• Nose

• Gap

Bevel Type 31

This bevel type is a Y-joint with an angle defined for the nose.

Relevant parameter:

• Alpha (α)

• Alpha 2 (α2)

• Nose

• Gap

Bevel Type 33

This bevel type is a variant of the Y-joint (type 30) where the "V"-shaped opening is replaced by a "U".

Relevant parameter:

• Alpha (α)

• Nose

• Radius

• Gap

Bevel Type 40

This bevel type is a "K" bevel, i.e. open in both directions with a nose. The bevel is symmetric, i.e. the opening angles in both directions are equal and the nose is centered in the middle of the plate.

Relevant parameter:

• Alpha (α)

• Nose

• Gap

Bevel Type 41

This bevel is an asymmetric variant of the bevel type 40. The asymmetry means that the opening angles on both sides of the bevel may be different and that the position of the nose must be defined. This is done as the distance (H) to the lower edge of the nose from the negative side, cf. the figure below.

Relevant parameter:

• Alpha (α)

• Beta (β)

• Nose

• H

• Gap

Bevel Type 42

This bevel type is a variant of the asymmetric K-joint (bevel type 41) where the "V"-shaped opening on both sides is replaced by "U"-shaped openings. The length of the nose and the radius of the "U" may be defined on both sides.

Relevant parameter:

• Alpha (α)

• Beta (β)

• Nose

• Nose Length A

• Nose Length B

• H

• Radius

• Radius B

• Gap

Bevel Type 43

This bevel type is a variant of the asymmetric K-joint (bevel type 41) where the "V"-shaped opening on the positive side is replaced by a "U".

Relevant parameter:

• Alpha (α)

• Beta (β)

• Nose

• H

• Radius

• Gap

Bevel Type 50

This bevel type is an X-bevel, i.e. open in both directions with a sharp knee. The bevel is symmetric, i.e. the opening angles in both directions are equal and the knee is centered in the middle of the plate.

Relevant parameter:

• Alpha (α)

• Gap

Bevel Type 51

This bevel is an asymmetric variant of the bevel type 50. The asymmetry means that the opening angles on both sides of the bevel may be different and that the position of the knee must be defined. This is done as the distance H in the figure below.

Relevant parameter:

• Alpha (α)

• Beta (β)

• Gap
