Welding consultancy, inspections and procedures
KEMA can assist you in providing engineering solutions for welding and repair problems in power and petrochemical industry
For lifetime extension of an installation partly old ‘used’ parts are to be replaced. In some cases it is attractive apply new developed materials. New and old materials need to be welded, while the materials have different compositions. For decades we have gained experience with different materials and different welding techniques for heavy loaded components. This knowledge is available in KEMA’s materials knowledge database. With this knowledge we can give you the right advice for the most suitable and reliable joints.
We provide welding consultancy, welding inspections, contract research, metallurgical assessments and welding procedures. Our expertise is supported by our welding procedure specifications database and qualified welding engineers. Overlay welding of water walls, welding of advanced creep resistant steels, weld repair of steam drums and gas turbine components are some of the examples where our services resulted in improvements in welding and repair technology and in optimized repair times and costs. We will help to maintain the organization’s reliability and flexibility in spite of reductions in manpower.
