Fillet Welding Bevels, General

Fillet welding differs from butt welding in two respects:

1. Normally the fillet welds have no variants, that means, only the basic bevel type is used.

2. Fillet bevel types may be fixed (like butt bevels) but they may also be varying.

Fixed fillet bevel types have constant bevel angles whereas varying bevel types have angles that may vary along the welding trace. The reason for this may be that the connection angle between the elements varies, for example, when a planar member of the internal structure is tightly connected to a shaped shell member.

Important features of the bevel handling are related to the connection angle between the connected elements:

3. AVEVA Marine automatically evaluates the connection angle as it varies along the edge.

4. AVEVA Marine has a facility automatically to pick different bevel types depending on the thickness of the abutting member and/or the connection angle.

5. Depending on the location of the mould plane and details of the cross-section of the bevel the nominal geometry of the abutting plate may have to be modified in a rather complicated way. This may be the case both for bevel types with fixed angles and for bevel types where the bevel varies.

Full details about various aspects of the AVEVA Marine support for the handling of fillet bevels are given in paragraphs below.
