What this video covers
Fabricating a custom anchor for an expedition vessel requires adding weight to the tip to ensure proper orientation and digging performance.2:50 To achieve this, the crew welds an additional 20mm steel layer to the anchor blade, notching the shank to allow for a deep, multi-pass weld.3:42 They use a 9-inch grinder with a cutoff disc to chamfer the edges, creating a V-groove that allows for full-penetration welds that are later ground flush.3:15 To prevent the thin leading edge from burning away during welding, they use a temporary steel backing plate.17:30 The design includes small gusset plates, or "shoulders," welded to the sides; these act as vanes to force the anchor to tip onto its point if it lands on its side on the seabed.10:52 After completing the structural welds and grinding the surfaces smooth, the crew sends the finished anchor for hot-dip galvanizing.22:14
