Assembly drawings should be dimensioned and labeled in a way to allow the welder to assemble and weld all parts together. This means an assembly drawing should show:

  • Plate and beam positions dimensioned to each other.
  • All parts should be dimensioned on visible views. No hidden lines should be dimensioned if possible. Additional views should be added to avoid this.
  • Running dimensioning are preferred by many welders
  • Hole size and position (hole size often only needs adding if it is not 22mm, standard hole size needs to be stated in the notes)
  • Weld type and size (weld size often only needs adding if it differs from the standard weld stated in the notes)
  • All part numbers need to be labeled for each part
  • The finish is stated on each drawing (such as galvanised or primed)
