weld_shape_teardrop command

Syntax:

weld_shape_teardrop width w case i 

• width w = keyword/value pair; w is pool width measured along y-axis

• case i = keyword/value pair; i takes on allowable values of I or II or III designating one of the following 3 teardrop shapes

Examples:

weld_shape_teardrop width 100.0 case I 

weld_shape_teardrop width 100.0 case II 

weld_shape_teardrop width 100.0 case III 

The three examples above are depicted in the images below. These images illustrate cases I, II and III for a fixed width of 100 sites. Because the width is fixed, each case produces a different pool length. NOTE: due to scaling for this documentation, constant width=100 for each pool shape is not perfectly rendered in images below although they are close.

Description:

Specify size and shape of weld pool at top surface of weld. Shape of pool at root surface (bottom) is controlled by alpha in potts/weld. The aspect ratio length/width for cases I, II, and III are 1.4, 1.8 and 2.2 respectively. If a specific width is desired then that is specified directly in the command and pool length is implied by the aspect ratio. On the other hand, if a specific length desired, then the input width must be calculated by hand using the desired length and aspect ratio.

Restrictions:

This command is only valid when used with potts/weld.
