Common Classification Parameters

There are a few classification parameters that are common across all the types of weld lines that can be detected by HyperLife Weld Certification.

Weld_Type

This parameter is automatically detected by HL-WC. The supported weld types are T, L, B, O, X and M welds. More information about weld types is available in The Weld Evaluation.

Weld_Category

Preset configurations for the classification parameters.

EvalDist Calculation Method

HL-WC allows two ways to calculate the evaluation distance using an automatic method and a manual method. The automatic method calculates the evaluation distance as a function of weld width and shell thickness of the components connected by the weld line. When using the manual method you can specify the distance in model units and HL-WC will use the value as is.

Resultant Weld Thickness (Ar)

Ar (resulting weld thickness) is user-defined input. Based on this parameter, there is a provision to reduce the stress values that are captured from FE in specific sheets of the connection according to the formula: Stress (corrected) = Stress (current) * Ar / shell thickness. This applies only to the stress normal to the weld and the shear stress. By default the value of Ar is set for the minimum shell thickness and then you can modify the value accordingly.
