Warning :

If your startup code specifies imperial Units("...") , make entries to distance fields on this window in decimal inches, not fractions. Also, do not use hyphens (-). If you enter a fraction using integers, Python truncates the results of the division operation to an integer (examples: 1/8 = 0 ; 5/4 = 1 ). If you enter fractions with decimal points, Python calculates the precise decimal value (examples: 1.0/8.0 = .125 ; 5.0/4.0 = 1.25 ). If you enter a hyphen, Python interprets the hyphen as a minus sign (examples: 1-2 = -1 ; 3-2 = 1 ). See numbers (floating point numbers and integers).

Tips :

To enter a dimension string and convert it to a floating point distance that is properly factored based on the startup code Units("...") , you can use the dim("...") function. See the warning above for an explanation of why the dim() function is needed.

------ General settings ------

Weld size ( obj . Size or obj.size ): A distance that indicates depth of preparation, size or strength of the weld. A distance is a floating point number in mm or inches, depending on the startup code Units(' ... ') . This distance is modeled in 3D as shown below.

Example: Units("feet") are your startup code units, and you want a 3/16 weld. You can make an entry of 0.1875 or dim("3/16") . An entry of 0.1875 results in a line of parametric code that reads: obj.Size = 0.1875 (where obj is the " Object name "). The equivalent entry of dim("3/16") would generate a line of parametric code that reads: obj.Size = dim("3/16") .

Minimum weld length ( obj . Length or obj.length ): The distance that is the minimum length of the weld that is allowed to be generated. A distance is a floating point number in mm or inches, depending on the startup code Units(' ... ') .

" Minimum weld length " is less than the flange thickness.
 " Minimum weld length " is greater than the flange thickness.

When this Python script is Run : If the minimum length entered here is longer than a to-be-welded edge or surface, that edge is not welded (as shown in the example above).

Example: Units("feet") are your startup code units, and you want a 1-3 minimum length. You can make an entry of 15.0 or dim("1-3") . An entry of 15.0 results in a line of parametric code that reads: obj.Length = 15.0 (where obj is the " Object name "). The equivalent entry of dim("1-3") would generate a line of parametric code that reads: obj.Length = dim("1-3") .

Maximum gap ( obj . MaximumGap or obj.max_gap ): The distance that to-be-welded materials must be closer together than. A distance is a floating point number in mm or inches, depending on the startup code Units(' ... ') .

" Maximum gap " is greater than the actual gap.
The actual gap is greater than the " Maximum gap ."

When this Python script is Run : If the maximum gap entered here is greater than the actual gap between the two pieces of material to be welded together, a weld is generated. If the actual gap is greater than the maximum, a weld is not generated.

Example: Units("feet") are your startup code units, and you want a 1/4 inch maximum gap. You can make an entry of 0.25 or dim("1/4") . An entry of 0.25 results in a line of parametric code that reads: obj.MaximumGap = 0.25 (where obj is the " Object name "). The equivalent entry of dim("1/4") would generate a line of parametric code that reads: obj.MaximumGap = dim("1/4") .

Left setback ( obj . LeftSetback or obj.left_setback ): A distance ( floating point number ) in mm or inches, depending on the startup code Units(' ... ') . This setback is the distance that the left end of the weld is to be set back from the edge of the material. 0 (zero) makes the left end of the weld go to the edge of the material that is being welded (the obj.Material in the code).

Example: Units("feet") are your startup code units, and you want a 3/4 inch left setback. You can make an entry of 0.75 or dim("3/4") . An entry of 0.75 results in a line of parametric code that reads: obj.LeftSetback = 0.75 (where obj is the " Object name "). The equivalent entry of dim("3/4") would generate a line of parametric code that reads: obj.LeftSetback = dim("3/4") .

Right setback ( obj . RightSetback or obj.right_setback ): A distance ( floating point number ) in mm or inches, depending on the startup code Units(' ... ') . This setback is the distance that the right end of the weld is to be set back from the edge of the material. 0 (zero) makes the right end of the weld go to the edge of the material that is being welded (the obj.Material in the code).

Example: Units("feet") are your startup code units, and you want a 3/4 inch right setback. You can make an entry of 0.75 or dim("3/4") . An entry of 0.75 results in a line of parametric code that reads: obj.RightSetback = 0.75 (where obj is the " Object name "). The equivalent entry of dim("3/4") would generate a line of parametric code that reads: obj.RightSetback = dim("3/4") .

Finish symbol ( obj . WeldSymbolFinishSymbol or obj.finish_symbol ): A single letter ( 1 character ) to appear on the weld symbol to designate the finishing operation (reference f/F in the illustration below). The choice you make here results in the entry of a string to the parametric code.

Note: If no entry is made here, then a line for finish symbol does not appear in the code.

Example: An entry of g results in a line of parametric code that reads: obj.WeldSymbolFinishSymbol = "g" (where obj is the " Object name ").

Weld-all-around ( obj . WeldAllAround or obj.all_around ): ( "Yes" ) or ( "No" ). The choice you make here results in the entry of a string (' Yes ' or ' No ') to the parametric code.

Weld-all-around
 Weld-all-around

If this box is checked ( ), a continuous weld is generated around every edge of the material, including material radii. The result is a line of parametric code that reads: obj.WeldAllAround = "Yes" (where obj is the " Object name ").

If the box is not checked ( ), weld is not generated on curved surfaces such as the fillet of a rolled shape. The result is a line of parametric code that reads: obj.WeldAllAround = "No" .

Weld inside surfaces ( obj . WeldInside or obj.inside ): ( "Yes" ) or ( "No" ). The choice you make here results in the entry of a string (' Yes ' or ' No ') to the parametric code.

  Weld inside ...
 Weld inside ...

If this box is checked ( ), both the inside and outside surfaces of a HSS round or HSS rectangular section are welded. The result is a line of parametric code that reads: obj.Inside = "Yes" (where obj is the " Object name ").

If the box is not checked ( ), only the outside of the HSS round or HSS rectangular material is welded. The result is a line of parametric code that reads: obj.Inside = "No" .

Field weld ( obj . FieldWeld or obj.field_weld ): ( "Yes" ) or ( "No" ). The choice you make here results in the entry of a string (' Yes ' or ' No ') to the parametric code.

If this box is checked ( ), the materials being welded together should be submaterials of different members. The result is a line of parametric code that reads: obj.FieldWeld = "Yes" (where obj is the " Object name ").

If the box is not checked ( ), the materials being welded should be submaterials of the same member. The result is a line of parametric code that reads: obj.FieldWeld = "No" .

 Stagger weld

If this box is checked ( ), you can enter a " Length " and " Spacing " to set the stagger pattern. The result is a line of parametric code that reads: obj.StaggerDescription = "Yes" (where obj is the " Object name ").

If the box is not checked , ( ), the weld is continuous (not staggered). The result is a line of parametric code that reads: obj.StaggerDescription = "No" .

Length ( obj . StaggerLength or obj.stagger_length ): The distance that is the length of each weld segment in a staggered weld. A distance is a floating point number in mm or inches, depending on the startup code Units(' ... ') .

ln = length

Example: Units("feet") are your startup code units, and you want a 4 1/2 inch stagger length. You can make an entry of 4.5 or dim("4 1/2") . An entry of 4.5 results in a line of parametric code that reads: obj.StaggerLength = 4.5 (where obj is the " Object name "). The equivalent entry of dim("4 1/2") would generate a line of parametric code that reads: obj.StaggerLength = dim("4 1/2") .

Spacing ( obj . StaggerSpacing or obj.stagger_length ): The distance from the beginning of one weld segment to the beginning of the next weld segment in a staggered weld. A distance is a floating point number in mm or inches, depending on the startup code Units(' ... ') .

sp = spacing

Example: Your " Units " are ' Imperial (ft-in frac) ' and you want a 5 1/2 inch spacing. You can make an entry of 5.5 or dim("5 1/2") . An entry of 5.5 results in a line of parametric code that reads: obj.StaggerSpacing = 5.5 (where obj is the " Object name "). The equivalent entry of dim("5 1/2") would generate a line of parametric code that reads: obj.StaggerSpacing = dim("5 1/2") .

Left termination ( obj . LeftTermination or obj.left_termination ): The distance that is the length of the weld segment at the left end of a staggered weld. A distance is a floating point number in mm or inches, depending on the startup code Units(' ... ') .

lt = left termination

Example: Units("feet") are your startup code units, and you want a 5 1/2 inch left termination. You can make an entry of 5.5 or dim("5 1/2") . An entry of 5.5 results in a line of parametric code that reads: obj.LeftTermination = 5.5 (where obj is the " Object name "). The equivalent entry of dim("5 1/2") would generate a line of parametric code that reads: obj.LeftTermination = dim("5 1/2") .

Right termination ( obj . RightTermination or obj.right_termination ): The distance that is the length of the weld segment at the right end of a staggered weld. A distance is a floating point number in mm or inches, depending on the startup code Units(' ... ') .

rt = right termination

Example: Units("feet") are your startup code units, and you want a 5 1/2 inch right termination. You can make an entry of 5.5 or dim("5 1/2") . An entry of 5.5 results in a line of parametric code that reads: obj.RightTermination = 5.5 (where obj is the " Object name "). The equivalent entry of dim("5 1/2") would generate a line of parametric code that reads: obj.RightTermination = dim("5 1/2") .

------ Prequalified weld settings ------

>
See Table 8-2, AISC Thirteenth Edition , p. 8-34 for more information on prequalified welded joints.

Use prequalified weld tail text ( obj . NonPrequalifiedWeld or obj.use_prequalified ): ( "Yes" ) or ( " No" ). The choice you make here results in the entry of a string (' Yes ' or ' No ') to the parametric code.

If this box is checked ( ), the options for " Joint type " " Joint designation " " Process " and " Position " are enabled. You can use these options to enter " Prequalified tail text ."

An entry of 0.25 results in a line of parametric code that reads: obj.RootOpening = 0.25 (where obj is the " Object name "). The equivalent entry of dim("1/4") would generate a line of parametric code that reads: obj.RootOpening = dim("1/4") .

Root face ( obj . RootFace or obj.root_face ): The distance that is labeled "rf" in the illustration below. A distance is a floating point number in mm or inches, depending on the startup code Units(' ... ') .

  rf = root face

Example: Units("feet") are your startup code units, and you want a 1/8 inch root face. You can make an entry of 0.125 or dim("1/8") . An entry of 0.125 results in a line of parametric code that reads: obj.RootFace = 0.125 (where obj is the " Object name ").

------ Supplementary tail text ------
( obj . WeldSymbolTailText or obj.tail_text )

To enter multi-line tail text such as that shown in the example below, press the Enter key where you want a line break.

Tail text entered here :
Tail text on weld symbol :

Example: If you enter multiple lines of tail text like that shown above, the resulting parametric code covers multiple lines as shown below:

obj.TailText = "Near &
Far Side"

------ Contour ------

Contour ( obj . WeldContourDescription or obj.contour ): None or Flush or Convex or Concave .

' None ' results in no contour symbol being included as part of the weld symbol. The result is a line of parametric code that reads: obj.WeldContourDescription = "None"

' Flush ' adds a flat line as the contour symbol to the weld symbol. The resulting parametric code reads: obj.WeldContourDescription = "Flush"

' Concave ' adds a concave line. The resulting parametric code reads: obj.WeldContourDescription = "Concave"

' Convex ' adds a convex line. The resulting parametric code reads: obj.WeldContourDescription = "Convex"
