We provide high-quality testing, inspection, and failure analysis to aid practicing engineers. Strain gages are small non-destructive sensors that allow us to measure engineering stress on any structure in real-time. We are the West Coast leader in applied strain gage solutions. Our extensive physical testing capabilities allow us to measure system performance directly.
Load, torque, deflection, fatigue and other testing services are available. Non-destructive testing (NDT) and field assessments of equipment allows us to find cracking, misalignment, corrosion, and wear so they can be addressed before they cause serious damage. Analysis of failures and fractures allow us to determine the cause of failure and propose solutions to prevent future failures.

Services
VGO is located in the heart of Portland, Oregon in the Central Eastside Industrial District. We maintain a 10,000 sq-ft facility which houses our test laboratory, machine shop, field equipment, metallurgical lab, and offices. VGO, Inc. was founded in 1970 as Van Gulik & Associates, Inc., by Joe Van Gulik, P.E.
Strain gages are devices that allow us to measure the actual stresses in a part or structure in real-time in a non-destructive way. This allows us to step aside from the assumptions that are required in engineering calculations and get actual data that shows the real state of stress. Since 1970, VGO has distinguished itself as a leader in applied strain gage technology on the West Coast.
A physical test can often answer engineering questions more quickly and simply than performing additional analysis. There are a number of labs that perform routine, standardized tests, such as tensile tests, Charpy impact tests, and chemical analysis. These firms have dedicated procedures, tooling, and personnel who perform the same test a high number of times.
Industrial clients with large equipment often require inspection for both routine maintenance and for determining the source of production problems. While there are firms that perform commodity NDT services, VGO sets itself apart by pairing engineers with NDT technicians.
This pairing allows the engineering significance of indications to be determined in real-time, closing the loop on which issues require immediate attention, and which can be monitored or disregarded.

Traditional metallurgical failure analysis involves laboratory analysis of a fracture surface and microstructure in order to determine the mode of failure, be it single overload, fatigue, environmental damage, corrosion, SCC, etc. While this is useful, most field failures involve a series of contributing factors which led to the failure, of which the final fracture is only one piece.
