Steels used onboard ships and how to perform maintenance welding
Despite many new materials being introduced into shipbuilding, steel is still what most ships are built from and is the most common metal that the welder onboard will encounter during maintenance welding. In below article the different kind of steels found onboard are briefly mentioned followed by application area and type of welding consumable to be used.
