• WeldedJoint

Derivated class of Joint with weld definition (see above)

# Python script
from Cwantic.MetaPiping.Core import WeldedJoint

joint1 = WeldedJoint()
...

// Property in metaL's JSON Elements list - inside Beam properties
    ...
    "Element": "Beam",
    "Joint1": {
        "Joint": "WeldedJoint",
        ...
        }
    ...  

The WeldedJoint has the same properties as the Joint plus :
