Design of Welded Connection Between Wind Turbine Tower and Baseplate
We designed a welded connection between a wind turbine monopole tower and its supporting baseplate to meet British Standard BS EN 1993-1-9:2005 and Eurocode 3 “Design of Steel Structures”. No suitable weldment configuration was available in Eurocode 3 to meet Detail Category 80 requirements for connecting the pole to the flat base plate. A full

Weld Repair of Mis-Machined Cast Turbine Blades
Turbine blades made from subject castings were in need of weld repairs caused by machining errors. When blades of specific materials are used in hydro-turbine units, they exhibit excellent erosion-corrosion resistance. Because of dimensional control issues, repairs need to be completed without a post-weld heat treatment (PWHT). The purpose of PWHT is to minimize the
