Shipbuilding and Marine Fabrication
Hull blocks, decks and marine structures are welded to class society rules, in position, often outdoors, and the weld metal has to keep its toughness at sub-zero temperature. Deposition rate decides the schedule, and toughness decides whether the joint passes.
Pain points
What Makes Consumable Selection Hard Here
- Class approval and the paperwork behind it, which is decided by the consumable as much as the procedure
- Low temperature impact toughness in the deposited metal on thick section joints
- Deposition rate in position, where a slow consumable holds up an entire block
- Corrosion behaviour on copper-nickel and aluminium components in seawater service

Shipbuilding and Marine Fabrication Questions
Which AKWELD grades are used in shipbuilding and marine fabrication?
Grades such as E71T-5M, ER5183, ERCuNiAl, E80C-Ni1 are the usual starting point. The exact choice depends on the base metal, the code and the service temperature.
Do you supply the data our inspector will ask for?
Each grade page publishes the classifications and chemical composition, plus mechanical properties where the factory datasheet gives them. Ask us for the test record for a specific batch.
Can you help with consumable selection for a specific project?
Yes. Send the base metal, the welding process, the position, the service temperature and the code, and our technical team will shortlist the grades that match.
What quantities do you supply for project work?
Project quantities are quoted against the schedule you send. Trial quantities are available first so the grade can be qualified on your own procedure.
Working on a Shipbuilding and Marine Fabrication Project?
Send the base metal, the code and the schedule. We will shortlist the grades and send the data your welding engineer needs.
