Hydroweld FS are the industry-standard wet welding electrodes where high-quality underwater welds are required. They are designed to produce high-quality welds underwater, in fresh water or seawater, in all positions, on a range of carbon steels and at a range of depths.
Hydroweld FS can meet or exceed the weld quality requirements of the AWS D3.6 code for underwater welding, Class A, in all positions on pipe and plate for fillet and butt welds, as witnessed by IACS members such as Lloyd's Register, ABS, DNV, Bureau Veritas and RINA. Hydroweld states they are approved by the UK Ministry of Defence for permanent and temporary repairs to naval ships and submarines.
