Slot Width Measurement
Holes or slots in the arrow side member of a joint for plug or slot welding must be indicated by placing the weld symbol on the side of the reference line toward the reader (A, fig. 3-11).
Length, width, spacing, included angle of countersink, orientation, and location of slot welds cannot be shown on the welding symbols. This data must be shown on the drawing or by a detail with a reference to it on the welding symbol, in accordance with location specifications given in paragraph 3-7 (D, fig. Ex: small radius nominal on the slot is.780' and large radius nominal is.995' making the nominal slot width.215'. I can easily measure cylinders on the small and large radii of the slot.
- Bag Limits (per person) BLUE CRAB (F) Recreational crabbing Blue crab info. 5” Carapace Width. 50 Crabs/Day not to exceed 100 Crabs/Vessel/Day. STONE CRAB CLAWS (J) 2 ¾' Propodus Length. UNLAWFUL TO POSSESS from June 15 – August 15 (no possession limit during open season) SPINY LOBSTER (K) 3” Carapace Length (L) 2/Day: HARD.
- Measure the width of a thread in fractions of an inch to get the diameter. Use a ruler or measuring tape to measure from one side of a thread to the other using the nearest fraction of an inch. This diameter for screws in the imperial system is represented by either a gauge number or in fractions of an inch.
Holes or slots in the other side member of a joint shall be indicated by placing the weld symbol on the side of the reference line away from the reader (B, fig. 3-11).
Neither the plug weld symbol nor the slot weld symbol may be used to designate fillet welds in holes.

Plug Weld Dimensions
Dimensions of plug welds must be shown on the same side of the reference line as the weld symbol. The size of a weld must be shown to the left of the weld symbol.
The included angle of countersink of plug welds must be the user’s standard unless otherwise indicated.
The included angle of countersink, when not the user’s standard, must be shown either above or below the weld symbol (A and C, fig. 3-34).
The pitch (center-to-center spacing) of plug welds shall be shown to the right of the weld symbol.

Dimensions, Details and Surface Contour of Plug or Slot Welds
Depth of Filling of Plug and Slot Welds
Depth of filling of plug and slot welds shall be completed unless otherwise indicated. When the depth of filling is less than complete, the depth of filling shall be shown in inches inside the weld symbol (B, fig. 3-34).
Surface Contour of Plug Welds and Slot Welds
Plug welds that are to be welded approximately flush without recourse to any method of finishing must be shown by adding the finish contour symbol to the weld symbol (fig. 3-35).
Plug welds that are to be welded flush by mechanical means must be shown by adding both the flush contour symbol and the user’s standard finish symbol to the weld symbol (fig. 3-36).
Slot Weld Dimensions
Dimensions of slot welds must be shown on the same side of the reference line as the weld symbol (fig. 3-37).
Details of Slot Welds
Length, width, spacing, included angle of countersink, orientation, and location of slot welds cannot be shown on the welding symbols.
