Hydroweld FS Underwater Welding Electrode Are the industry standard wet welding electrodes where high quality underwater welding is required.  These unique electrodes specifically designed to produce high quality welds underwater, in freshwater or brine/seawater, in all positions and on a range of carbon steels and depths of water.  Their outstanding user friendly properties and wet welding characteristics have made them the electrodes of choice by professional wet welders around the world.

Hydroweld FS are the result of significant research and development into flux formulations, filler metals and supplementary coatings.  This research and subsequent development was specifically aimed at addressing the metallurgical, weldability and practical issues commonly associated with underwater welding so enabling a significant improvement in wet weld quality unattainable by other currently available wet welding electrodes.

Hydroweld FS™ have gained an unrivalled, proven, track record in the field particularly for structural wet welding in all sectors of the industry including the offshore oil and gas, naval/merchant shipping, civil/marine/inshore and nuclear industries.  As a result of their reliability and performance they are generally accepted as the industry standard for wet welding.

Hydroweld FS™ can/have meet or exceed the weld quality requirements of the AWS D3.6 Code for underwater welding, ‘Class A’ weld criterion in all positions on pipe and plate for both fillet and butt welds as has been witnessed by international recognised IACS (international Association of classification Societies) members such as Lloyds Register (LR), American Bureau of Shipping (ABS), Det Norske Veritas (DNV) / Germanisher Lloyd (GL), Bureau Veritas (BV) and Rina.

Hydroweld FS™ wet welds are regularly subjected to unparalleled, intensive testing and on research programmes by independent organisation such as welding institutes, universities, military/naval organisations, commercial diving contractors and other recognised organisations around the world.

Hydroweld FS™ are currently the only wet welding electrodes approved for permanent and/or temporary repairs to naval ships and submarines by the British Ministry of Defence (MoD) and listed in the NATO codification system (NCAGE) KA125, being approved for inclusion after intensive comparability testing against a range of other commercially available wet welding electrodes by the MoD and The Welding Institute (TWI) and subjected to extensive non-destructive and destructive testing.

Hydroweld FS Underwater Welding Electrodes are currently available in 3.2 mm x 350 mm in boxes of 90 electrodes or 4 mm x 350 mm in boxes of 60 electrodes and/or cartons of 5 boxes.
