PHYSICAL TESTING provides the testing for the certification of welding procedures and/or welders. In the fabrication of certain structures specific welding techniques have to be developed. These procedures are tested to find out if the end product meets specifications. We test physical properties of various metals and composite structures as well as other materials used in the construction and manufacturing of: Nuclear reactors, wind generators, hydrofoil parts, trucks, cranes, gears, foundry products, cables, mountain climbing gear, ballistic missiles, ferry boats, building materials, crude oil pipelines, power lines, ships and more. We cover a large area, and with the advent of new materials our experience grows almost daily.





 

"Builders of a dam had a problem. As the concrete set, it heated up. This in turn made the concrete shrink which formed cracks. Problem: avoid shrinkage so no cracks will form. In the area where the dam was being constructed there was found a volcanic deposit called Pumicite. We determined that the Pumicite could be calcined to produce a material with pozzolanic properties. When mixed with the cement it reduced shrinkage to acceptable limits, and actually increased the strength. The cost savings realized by this solution was in the millions of dollars."
