DESCRIPTION DWG NO. REV.

1) Where beams, stiffeners, frames, etc., pass through slotted girders, shelves or stringers, there is to be a pair of matched intermittent welds on each side of each such intersection, and the beams, stiffeners and frames are to be efficiently attached to the girders, shelves and stringers.

2) Longitudinal frames are to have 6 inches of double continuous welding at their ends and in way of transverses. Deck longitudinals require

6 inches double continuous welding at ends.

3) The required welding area of end connections of stanchions and diagonals is not to be less than the following:

● Stanchions –75% of the area of the stanchions

● Diagonals – 50% of the area of the diagonal

In determining the weld area provided, the throat dimension of the fillet is to be used.

4) Brackets generally welded 3 inches on 6 inches centers, both sides. Length of fillet weld based on lesser thickness of members joined.

5) Unbracketed shell and bulkhead stiffeners are to have double continuous welds for one-tenth of their length at each end.

6) Fillet welds are defined by Leg Size (w), Length of Fillets (l), and Spacing of Fillets (S) in inches, in accordance with ABS Rules for Building and Classing Steel Vessels for Service on Rivers and Intracoastal Waterways (2021).

7) Steel welds designed to ABS Rules for Building and Classing Steel Vessels for Service on Rivers and Intracoastal Waterways, under which the vessel is to be classed. Aluminum welds designed to ABS Rules for Building and Classing Light Warships, Patrol and High-Speed Naval

Vessels per MVR.

8) Where joints are lapped, welds are to be continuous on both sides with thickness equal to 3/4 the thinner plate thickness.

9) Where beams, stiffeners, frames, girders, etc. terminate, they are to be continuously welded on both sides with thickness equal to 3/4 of the thinner plate thickness.

10) All welding in tanks and voids that boundary the shell shall be double continuous for additional corrosion protection.

11) Detacouple welds to be made in accordance with manufacturer recommendations.

12) Filler matals shall comply with applicable ABS requirements; recommended electrodes are:

● E7108 (SMAW), E71T-/ER70S- series (FCAW-G/GMAW) for mild steel structures

● 308L for 304SS to 304SS and 309L for 304SS to mild steel

● 5183 for 5083 plate butts; 5356 for attachment of 6061 structurals to 5083 plate; 4043 for attchment of 6061 structurals to 6061 structurals
