¿Qué cubre este video?
Welding steel doublers onto the deck and hull of a converted fishing trawler provides the necessary structural reinforcement for mounting deployable wing arms.0:02 The process involves cleaning surface rust and primer from the steel, then tacking and perimeter-welding the 150mm-deep doubler plates.1:35 When a gas-shielded welder fails due to a suspected line blockage, switching to flux-core wire allows the work to continue.4:00 To ensure the half-inch thick steel plates sit flush against the deck, the crew uses a lever-and-hook system, supplemented by steel wedges to close gaps where the deck surface is uneven.11:22 The team also grinds down excess material from previous sponson cuts to clear space for the mounting hardware.3:14 Because the final alignment of the wing arms and sliders remains uncertain, the crew pauses the installation of M30 high-tensile threaded rod mounts to avoid premature drilling.15:44 The project now shifts to fabricating sliders to finalize the geometry of the wing deployment mechanism.16:11 Using a lever and wedge system effectively pulls thick steel plate flush against an irregular deck surface.13:32
