6.3.4.10.3 Properties

Name Property Type Data Type Description
Type1 IfcPropertySingleValue IfcLabel

Type of weld seam according to ISO 2553. Note, combined welds are given by two corresponding symbols in the direction of the normal axis of the coordinate system. For example, an X weld is specified by Type1 = 'V' and Type2 = 'V'.

Type2 IfcPropertySingleValue IfcLabel

See Type1.

Surface1 IfcPropertySingleValue IfcLabel

Aspect of weld seam surface, i.e. 'plane', 'curved' or 'hollow'. Combined welds are given by two corresponding symbols analogous to Type1 and Type2.

Surface2 IfcPropertySingleValue IfcLabel

See Surface1.

Process IfcPropertySingleValue IfcInteger

Reference number of the welding process according to ISO 4063, an up to three digits long code

ProcessName IfcPropertySingleValue IfcLabel

Name of the welding process. Alternative to the numeric Process property.

NominalThroatThickness IfcPropertySingleValue IfcPositiveLengthMeasure

Design value of the height of the largest isosceles triangle that can be inscribed in the section of a fillet weld.

WeldWidth IfcPropertySingleValue IfcPositiveLengthMeasure

Required elongated hole width at the faying surface or seam weld width at the faying surface.

WeldDiameter IfcPropertySingleValue IfcPositiveLengthMeasure

Dimension of the required hole diameter at the faying surface, or required spot weld diameter at the faying surface, or required stud diameter.

WeldElementSpacing IfcPropertySingleValue IfcPositiveLengthMeasure

Spacing between weld elements (centre to centre)

WeldElementLength IfcPropertySingleValue IfcPositiveLengthMeasure

Length of each weld element.

NumberOfWeldElements IfcPropertySingleValue IfcCountMeasure

Number of weld elements.

DeepPenetrationThroatThickness IfcPropertySingleValue IfcPositiveLengthMeasure

Nominal throat thickness or effective throat thickness to which a certain amount of fusion penetration is added.

WeldLegLength IfcPropertySingleValue IfcPositiveLengthMeasure

Distance from the actual or projected intersection of the fusion faces and the toe of a fillet weld, measured across the fusion face.

Intermittent IfcPropertySingleValue IfcBoolean

If fillet weld, intermittent or not

Staggered IfcPropertySingleValue IfcBoolean

If intermittent weld, staggered or not
