Editing the Parabuild ISO Weld Dialog

  1. The Arrow is at the point of the mouse pointer and should be placed at the weld position
  2. The Leader will stretch in compliance with the movement of the mouse pointer
  3. The Reference line contains all the weld information for the weld on the near side of the plate being welded
  4. The Weld type is to indicate whether the weld is to be only at the indicated position or all-round - select either from the dialog

 


5.   Shop or Field weld - select either from the dialog

   

6.   Weld size - With the ISO system, the weld size is placed to the left of the weld symbol and is preceded by the letters: (z) / (a) / or (z) - depending on whether the leg length or throat thickness is to be specified. Unless otherwise instructed, it is usually the leg length that is specified, in which case only the (z) box needs to be added. If the throat size is to be specified, only the (a) box needs to be entered.
