Electron Beam Welding of Steel Diaphragm for the Power Generation Industry

An oil and gas client in New York commonly asks KTI, Inc. to apply our electron beam welding capabilities to steam turbine diaphragms.

Following customer specifications, we electron beam welded the part photographed using a custom rotary fixture. The part consisted of low carbon/stainless steel materials and had an ultimate height of 4.5" and an outside diameter of 73". The welding requirements included a weld penetration depth of .900" (partial) from each side, at diameters of 44" and 67".

Upon completion, the part was shipped to our customer in New York and installed in a turbine being refurbished. Our expedited delivery resulted in minimal system downtime for the power generation company.
