摘要: The method according to these exemplary embodiments provides welding techniques for impeller blades (60) associated with impellers in centrifugal compressors. According one embodiment, a connection area of the blade has "hammer" - shaped cross sectional (70) which facilitates beam slot surface or body is be connected.
