Welding consumables specifically customized for heat-resistant steels for thermal power fleet components. Oerlikon meets the highest technical demand in complex environment and applications.

Oerlikon provides solutions for thermal power generation applications, in the field of the fabrication and the maintenance. Oerlikon commits to technical  excellence and expertise supported by a dedication to quality, which is  fundamental to Oerlikon success with thermal power designers and fabricators worldwide.

Welding consumables for thermal power generation applications

For over 30 years, Oerlikon has offered the highest quality solutions using the widest range of technical expertise combined with relevant and consistent quality assurance and quality control management.
A special manufacturing programme dedicated to power generation components regarding the formulation and design of Oerlikon welding consumables range has been implemented.


Thus assuring consistently low levels of trace elements as well as a very high level of weld metal . The ISO 9001 Quality System Certificates enable us to manufacture and supply high technical welding products for use in the thermal power generation sector. The Oerlikon “Thermal Power Generation” range conforms to the most technical fossil power industry specifications, including the last generation of ultra-supercritical thermal power fleets. Oerlikon provides a wide range of major players in the field of boilers, tubes and pipes, steam turbine manufacturers, water walls, super heaters, reheaters, headers and cast steel foundries.

Solutions for P91 and P92 creep resistance applications

Material developments such as creep advanced 9%Cr resisting steels for high temperature and high pressure components, still play a big role in the new projects in the field of the super-critical and Ultra-supercritical steam parameters applications.
The T/P91 (9%CrMo) materials are now well recognized and in use worldwide. A specific focus have been engaged some years ago to more advanced grades such as T/P92 and this steel has already been welded in some projects in Europe, USA, Japan and China.
Even though these T/P92 materials are used at high temperature, where toughness is not a matter of concern, it is important that the welded joints show also a good toughness at room temperature, for fabrication and construction steps and for start-up and shut down considerations.
