Geometry to be Used for Creating Welds

The following references show you the appropriate geometry you need to select to create a given weld type:
  Two other references described the weld propagation and the symmetrical or double weld:
 

Fillet Weld
 
  Plane Sphere Cylinder Cone Prismatic
Plane Intersection Intersection Intersection and perpendicularity or intersection and parallelism Intersection and perpendicularity Intersection and perpendicularity or intersection and parallelism
Sphere   Intersection Intersection and concentricity Intersection and concentricity Impossible
Cylinder     Intersection and parallelism Intersection and coaxiality Intersection and parallelism
Cone       Intersection and coaxiality Impossible
Prismatic         Impossible
 

Groove
 
Surface to be welded Plane Prismatic
Plane Coincident Impossible
Prismatic   Not available
 
Types of both upper surfaces Plane Cylinder Sphere
Plane Coincident and perpendicular to the surfaces to be welded Impossible Impossible
Cylinder Coincident and axes perpendicular to the surfaces to be welded Impossible
Sphere Not available
 

Square Groove
 
  • The height of both surfaces must be equal and constant.
  • The bottom surfaces must be parallel to upper surfaces.
 

V Groove
 
  • The height of both surfaces must be equal and constant.
 

Bevel Groove
 
  • The height of both surfaces must be equal and constant.
 

Weld Propagation
  A weld can be propagated on the adjacent and tangent surfaces. Furthermore, for a symmetrical or double weld, these surfaces must also respect the symmetrical rules.
 

Symmetrical Weld
  The selected surfaces for a symmetrical or double weld must have a constant offset between them, and their orientation must be opposite.
