Weld Repair

ARGONNE NATIONAL LABORATORY

Is one of several U.S government operated large research facilities. When an ARGONNE program required a multiple number of highly precise titanium workpieces, involving extensive, high-stock removal machining, they specified VSR Technology Group’s VSR-8000 Vibratory Stress Relief System to assure consistent dimensional quality.

VOITH SIEMENS JOB #2

VOITH-SIEMENS is a manufacturer of power generation systems. One of their more recent designs involved the use of both low-carbon and austenitic stainless steels in the construction of a 4-quadrant hydro-turbine bottom ring. The VSR Process was used to prevent distortion occurring during either final machining, or the transport of the disassembled bottom ring to the installation site.

VOITH SIEMENS JOB #1

A manufacturer of hydro-turbine equipment used for power generation received an order to replace 4 tons of cavitated cast steel in 100,000 lb. bottom ring assembly, they chose the vibratory stress relief process to assure stability throughout fabrication and machining. The result was not only an 80% to 90% reduction of distortion at a critical stage in the fabrication process, but also a considerably more stable work piece during final machining.

MIDWEST FORGE (MWF)

Back in 1989 MIDWEST FORGE (MWF) of Cleveland, OH faced a costly decision. One of their larger presses (8000 ton capacity) had broken due to overload. Tooling had been installed and parts processed which required press tonnages 25% beyond the press’s capacity. Within a short time, the press was down. Several cracks had appeared and they were growing.
