Proserv have pioneered the development of portable friction stud welding systems, allowing this time proven welding technique to be used in topside zoned areas and in subsea environments using ROV’s. Friction welding is a long established joining process which is utilised in renewables and oil and gas industries.

The Friction Welding Process is a solid-state (no melting of materials) welding process that produces a fine grain forged weld by using the heat generated between a rotating part under an axial load and a fixed substrate. Heat for welding is generated by direct conversion of mechanical energy to thermal energy at the interface of the work pieces without the need for the application of electrical energy or heat from other sources. This delivers a weld connection with superior fatigue life and without compromising the integrity and design life of the parent material and structure. These characteristics have made this technology the perfect choice for attaching anodes onto fatigue driven structures like ship hulls and offshore wind farms.

This technology can also be used in zoned areas where it is commonly utilised for the installation of fire walls and attachment of corrosion sensors on pipelines.
