What this video covers
Fabrication of the expedition trawler’s wings requires precise alignment of 16mm steel hinge plates to ensure structural integrity during operation.5:14 To distribute the load from the hinges into the wing’s internal framework, the process involves welding internal doublers and gussets before capping the wing ends.0:38 Because the 16mm steel plate requires bending to match the wing profile, alignment is achieved by using a 2-inch 316 stainless steel pipe as a guide to ensure the hinge holes remain true.8:13 The fabrication process includes tack-welding the plates, sandblasting the joints to ensure a clean surface for final welding, and planning for diagonal bracing to mitigate tension on the hinge welds.10:15 The design incorporates a gusset between the hinge plate and the wing’s internal strong-back to transfer stress away from the primary welds and into the center of the wing structure.15:07
