METHOD FOR A WELDING PROCESS CONTROL OF NICKEL BASED SUPERALLOY PRODUCTS

摘要

A method for a welding process control of Nickel-based superalloy products, especially for gas turbine components, which method includes generating a welding pattern basing on data relating to the geometry of welded products, the material of welded products and the parameters of the selected welding technology and welding equipment, performing a virtual welding using said welding pattern and assessing the quality of welding joint. According to the invention one can make a conclusion whether the selected welding parameters are appropriate for the given alloy composition, welding technology and geometry of the products to be welded and geometry of welding joint, and subsequent realize the welding process in optimal conditions basing on the welding pattern. The invention will bring substantial economic benefit since the number of expensive trials and rejection of welded products will be significantly reduced or even eliminated.
