Kelvion Thermal Solutions optimises its welding processes.
Welding quality is fundamental to Kelvion Thermal Solutions, a manufacturer of heat exchangers for industrial applications. Hence the surprise when cracks suddenly appeared on the welds of manifolds made from Incolloy 825; its production experts immediately carried out a thorough investigation to determine the root causes and find solutions. With Cetim’s assistance, they used the 5M approach to examine the possible causes and found an intergranular brittleness at the welds. “In collaboration with Cetim, we then designed a welding procedure, which, through a modification of the bevels on the parts, led to a reduction in the energy required for welding. The result is now perfect again”, stated Olivier Bonin, head of the industrial production, methods and maintenance department.
